Tariff Concession Orders (TCOs): How Australian Importers Legally Pay Zero Duty

Ask a hundred Australian importers whether they checked the TCO register before their last shipment and you will get a lot of blank looks. Most have never heard of it. Yet the register is a public list of goods the government has already agreed should enter Australia duty-free — no free trade agreement required, no certificate of origin, no negotiation. If your goods match a Tariff Concession Order, the 5% general duty rate simply disappears.

Invert the usual question for a moment. Importers spend enormous energy asking “how do I reduce my duty?” — chasing FTA paperwork, arguing classifications, restructuring supply chains. The better question is often “has someone already eliminated this duty, and did I bother to look?” For thousands of tariff lines, the answer to the first half is yes. The answer to the second half, for most importers, is no. That gap is where real money sits.

This guide covers what a TCO actually is, how to search the register and read a concession properly (the wording is decisive, and it bites), how to claim an existing TCO, how to apply for a new one, the revocation risk, and when a TCO beats an FTA. We will put numbers on it too: on a typical AUD 400,000 machinery import, an existing TCO is worth AUD 20,000 — for the cost of a register search and one line on a declaration.

What a Tariff Concession Order Actually Is

A Tariff Concession Order is a legal instrument, administered by the Australian Border Force (ABF), that makes a specifically described good duty-free when imported into Australia. Not reduced duty. Zero.

The logic behind the scheme is refreshingly clean. Tariffs exist to protect local industry: a 5% duty on imported widgets makes Australian-made widgets relatively cheaper, shielding local manufacturers from foreign competition. But what if nobody in Australia makes widgets — or anything substitutable for them? Then the tariff protects no one. It is just a tax on Australian businesses that have no choice but to import. The TCO system exists to remove exactly that dead-weight tax: where no Australian manufacturer produces substitutable goods in the ordinary course of business, a concession can be made and the duty falls away.

That single test — no substitutable Australian-made goods in the ordinary course of business — is the spine of the entire system. It determines whether a new TCO can be granted, and it determines whether an existing one survives. Everything else is mechanics.

A few structural points worth fixing in your head early:

• TCOs attach to goods, not importers. Once a TCO exists, any importer whose goods match it can use it. You do not need to be the applicant. Most TCOs in the register were applied for by someone else years ago, and they sit there available to anyone who checks.
• TCOs are origin-independent. Unlike FTA preferences, a TCO does not care where the goods were made. Germany, India, Brazil, anywhere — if the goods match, the concession applies.
• TCOs are made under a specific tariff classification. Each TCO hangs off a tariff code. Your declared classification must match the TCO’s classification, or the concession cannot be claimed at all — more on this trap later.
• The register is public. Thousands of TCOs are in force at any time, searchable by anyone, for free.

Note what a TCO does not remove: GST is still payable on the import (though most registered businesses claim it back as an input tax credit), and other charges such as import processing charges still apply. The TCO eliminates customs duty — which, at the general rate of 5% of customs value, is usually the number that matters.

Finding an Existing TCO: Searching the Register

The starting point is your tariff classification. Every TCO is made under a specific tariff code, so you cannot search meaningfully until you know — with confidence — how your goods classify. If your classification is shaky, fix that first; a TCO search built on a wrong code will either miss the concession that exists or find one you cannot lawfully use.

With the code in hand, you search the TCO register (published by the ABF) by tariff classification. The search returns every concession in force under that code, each with a TCO number, an operative date, and — critically — a description of the goods covered.

The wording is the whole game

Here is the part that catches people. A TCO does not cover “goods of heading 8479” or “machinery like the applicant’s.” It covers goods matching a precise verbal description, and your goods must match that description exactly. Not approximately. Not in spirit. The words of the concession are decisive, and customs tribunals have spent decades confirming that the description means what it says — no more, no less.

Consider a realistic TCO text, structured the way real ones are:

MACHINES, LABELLING, self-adhesive label, having ALL of the following: (a) label application speed exceeding 200 labels per minute; (b) programmable logic controller; (c) label sensor with automatic web-break detection

Read this the way a customs officer will. The head noun is MACHINES, LABELLING — so the goods must be labelling machines, full stop. The qualifier “self-adhesive label” narrows it: a machine applying glue-applied labels is outside the concession. Then “having ALL of the following” imposes three cumulative conditions. A machine that applies self-adhesive labels at 180 per minute fails condition (a) and gets nothing, even though it is in every commercial sense the same kind of machine. Each condition is a gate; miss one and the concession does not apply.

Some TCOs run the other way and use expansive drafting. You will see descriptions ending in phrases like “including” lists, or conditions framed as “having EITHER of the following,” or the word “other” doing quiet work — as in PUMPS, centrifugal, other than submersible. That “other than” is an exclusion: submersible centrifugal pumps are carved out. Meanwhile a description like PARTS, machine, being ANY of the following followed by a list operates as a menu — matching any single item is enough. The drafting conventions (ALL / ANY / EITHER in capitals, exclusions flagged with “other than” or “excluding”) are consistent, and learning to read them takes twenty minutes that can be worth twenty thousand dollars.

Practical search habits that pay off:

• Search the full code and the neighbouring codes. If your classification is arguable between two headings, check the register under both — partly to find concessions, partly because a TCO under a neighbouring code may hint at where similar goods have been classified before.
• Read every concession under the code, not just the first plausible one. Multiple TCOs often exist under one classification, with different scopes. The third one down may fit when the first does not.
• Match your goods’ actual specifications against each condition in writing. Get the technical datasheet, put it next to the TCO text, and tick each element. If you cannot tick every element of an “ALL of the following” concession with documentary support, do not claim it.
• Check the concession is still in force. The register shows operative and (where relevant) revocation dates. A revoked TCO helps you only for imports before the revocation date.

Using an Existing TCO: The Mechanics of the Claim

Claiming an existing TCO is almost anticlimactic. On the import declaration, against the relevant line, you (or in practice your customs broker) quote a treatment code indicating a tariff concession and cite the TCO number. Duty on that line is calculated at zero. There is no application, no approval letter, no waiting — the concession already exists; you are simply invoking it.

The broker’s role here deserves a frank word. A good broker will proactively check the register for every new product a client imports and will flag candidate TCOs. Many brokers do exactly this. But brokers process high volumes at thin margins, and a register check for a client who has not asked for one is unbilled diligence. It is entirely possible — common, even — for goods with a valid TCO available to be entered at the full 5% for years because nobody looked. The importer assumes the broker checks; the broker assumes the importer would have mentioned it. Do not let the concession fall into that gap. Ask your broker directly: has the TCO register been checked against our tariff classifications, and when?

The classification-must-match trap

One mechanical trap disqualifies otherwise perfect claims: the TCO can only be used if your goods are classified to the same tariff code the TCO is made under.

Suppose a TCO for your exact machine exists under heading 8422, but you and your broker have concluded the machine properly classifies to 8438. You cannot quote the 8422 TCO against an 8438 entry — the system will not marry them, and lawfully they do not marry. Your options are to revisit the classification (perhaps the TCO’s existence under 8422 reflects a considered ABF view of where such goods belong, which is evidence worth weighing), to seek a formal tariff advice from the ABF to settle the classification, or to apply for a new TCO under the classification you believe is correct.

What you must not do is bend the classification to reach the concession. Classifying goods to a code you know is wrong, in order to access a TCO under that code, is a false statement on a customs declaration. The duty saving is not worth the exposure. Classification first, honestly determined; then see which concessions live there.

Applying for a New TCO

If no existing TCO fits, and you import the goods regularly, applying for a new one is a genuine option — and less daunting than most importers assume. The scheme is designed to be used.

The eligibility test

The core criterion: on the day the application is lodged, no Australian manufacturer produces substitutable goods in the ordinary course of business. Unpack the phrases:

• Substitutable goods means Australian-made goods with a use corresponding to a use of the imported goods. It is a use-based test, not an identity test. The local product does not need to be identical, the same quality, or even the same price — if it can be put to a corresponding use, it is substitutable and the TCO fails. This is deliberately broad and it is where most contested applications are fought.
• Ordinary course of business filters out theoretical capability. A local firm that could make the goods if someone asked, or made them once in 2019, is generally not producing them in the ordinary course of business. But a firm that makes them to order as part of its normal activities may well be.

Certain goods are excluded from the TCO system regardless — broadly, foodstuffs, clothing, and passenger motor vehicles sit outside the scheme, reflecting industries where tariff policy is handled differently. If your goods are industrial equipment, components, instruments, or specialised inputs, you are in the scheme’s heartland.

Process and timeline

The sequence runs like this:

1. Lodge the application with the ABF, including a precise proposed description of the goods (you are drafting the very wording future importers will live with — draft it carefully), the tariff classification, and evidence supporting the claim that no substitutable local goods exist.
2. Gazette publication. Valid applications are published, putting Australian industry on notice.
3. Objection window. Local manufacturers have a defined period (50 days from gazettal) to object on the ground that they produce substitutable goods. An objection turns the application into a contest of evidence.
4. Decision. The ABF must decide within the statutory timeframe. In practice, budget roughly 150 days end to end from lodgement to decision.

Two timing features make the economics better than they first appear. First, if granted, a TCO generally operates from the date the application was lodged — so imports made while you waited can have their duty refunded. Lodge, keep importing, and treat the duty paid in the interim as a recoverable deposit rather than a sunk cost. Second, once made, the TCO is public: your competitors can use it too. Some applicants find that galling; the arithmetic rarely supports waiting for someone else to do the work instead.

The evidence burden

The application stands or falls on market research. You are proving a negative — that no substitutable Australian-made goods exist — which means demonstrating you looked properly. Strong applications typically show:

• Searches of Australian manufacturer directories and industry association member lists for firms plausibly making comparable goods;
• Direct enquiries to any candidate local manufacturers, with their responses documented (“we do not manufacture this class of equipment” in writing is gold);
• Technical analysis explaining why superficially similar local products do not have a corresponding use — this is where engineering detail earns its keep;
• Evidence of how the goods are actually procured in the Australian market (if every buyer imports, that itself says something).

Skimping here is the classic false economy. A thin application invites objection and refusal; a thorough one often deters objection entirely, because a local manufacturer reading a well-evidenced gazettal can see the objection would fail.

The Revocation Risk

A TCO is not a permanent entitlement. The premise of every concession is the absence of local manufacture — and premises can stop being true.

If an Australian manufacturer begins producing substitutable goods in the ordinary course of business, they can apply to have the TCO revoked. The ABF assesses the claim on the same substitutability test used at grant. If the revocation succeeds, duty is reinstated going forward: imports entered before the revocation takes effect keep the concession; imports after it pay full duty. Revocation is not retrospective punishment — nobody claws back your past savings — but it can put a 5% hole in your forward costings with limited warning.

The warning that does exist comes through gazette notices. Revocation requests and decisions are published, just as applications are. Which creates a simple operational rule for any importer whose margins lean on a TCO:

• Keep a live list of every TCO number you rely on, with the tariff code and annual duty saving attached to each — so you know what is at stake per concession.
• Monitor gazette notices for revocation activity touching those TCOs or their tariff codes. This is a five-minute periodic check, easily delegated to your broker as a standing instruction.
• Model your landed costs both ways. If a AUD 20,000-a-year saving would break the business case for a product line, you want to know before the revocation notice, not after. Treat the TCO as a probability-weighted saving, not a birthright.

ABF can also revoke a TCO on its own initiative in some circumstances — for instance where the concession was made in error or the goods description has been overtaken by tariff changes. Rare, but another reason the standing gazette check is worth having.

TCOs vs FTAs: Which Tool, When

Australia has free trade agreements covering most major trading partners, and FTA preference is the duty-saving route importers hear about constantly. So where does a TCO fit alongside them?

The first thing to say: you use one or the other on a given line, not both. Duty is either zero via TCO or zero (or reduced) via FTA preference; there is nothing to stack. The question is which claim to make — and sometimes only one is available.

The TCO’s structural advantage is origin-independence. An FTA preference requires the goods to originate in the partner country under that agreement’s rules of origin (RoO), evidenced by origin documentation. A TCO asks only one question: do the goods match the description? Where they were made is irrelevant. That gives the TCO a clear win in three situations:

• No FTA with the origin country. Germany and the wider EU are the headline example for machinery importers — at the time of writing there is no in-force Australia–EU trade agreement, so German, Italian, and Swiss-adjacent equipment pays the general 5% rate unless a TCO covers it. Same story for goods from the UK’s non-covered categories’ edge cases, Taiwan, Brazil, South Africa, and plenty of others. For these origins, the TCO register is effectively the only zero-duty route.
• FTA exists but the goods fail rules of origin. Goods shipped from an FTA partner do not automatically qualify — RoO tests (change of tariff classification, regional value content) trip up goods with heavy third-country inputs. A Chinese-assembled machine full of Japanese and German components may not qualify as Chinese-originating under ChAFTA. If a TCO covers the goods, the origin question evaporates.
• FTA paperwork is not worth the friction. Even where preference is available, it comes with certificates of origin, supplier declarations, and audit exposure if the origin claim is ever tested. A valid TCO makes all of that unnecessary: no certificate, no RoO analysis, no dependence on a supplier’s paperwork discipline. For goods covered by both routes, many brokers will claim the TCO precisely because it is the cleaner instrument.

The FTA wins, conversely, when no TCO matches your goods and none is realistically grantable — most commonly because an Australian manufacturer does make substitutable goods. Consumer products, food, apparel, and generic industrial goods usually live in FTA territory. Specialised capital equipment lives in TCO territory. Many importers need both tools across their catalogue; the mistake is knowing only one exists. For the FTA side of the decision, see our companion guide on Australia’s free trade agreements for importers.

Worked Example 1: German Machinery, Existing TCO, AUD 20,000 Saved

An Adelaide food processor orders a specialised depositing and filling line from a German manufacturer. Numbers:

• Machine price (customs value after adjustments): AUD 400,000
• Origin: Germany — no FTA, so the default duty rate is the general 5%
• Duty at 5%: AUD 20,000
• GST is payable on the value-of-taxable-importation either way and is recoverable as an input credit, so we set it aside; note only that duty itself inflates the GST base slightly, so killing the duty trims the GST cashflow too.

The importer’s broker classifies the machine and, as a matter of routine, searches the TCO register under that code. A concession exists — applied for years earlier by a different importer of similar equipment — describing depositing machines with specifications the German line meets on every element. The broker matches the manufacturer’s datasheet against each condition of the TCO text, confirms the classification on the entry is the code the TCO is made under, and quotes the TCO number on the import declaration.

Result: duty AUD 0 instead of AUD 20,000. Time cost: perhaps an hour of register search and datasheet matching. There was no application, no waiting period, no dependence on German origin paperwork — the concession was sitting in a public register, available to anyone who looked. On a machine this size the saving is 5% of the capital cost, which for many equipment purchases is the difference between the business case clearing its hurdle rate or not.

Run the counterfactual, because it is the common case: the importer who never checks pays the AUD 20,000 without ever knowing it was optional. No error message, no missed-savings alert on the declaration. The system will happily take full duty forever. If you are importing capital equipment, pair this check with our guide to importing machinery to Australia, which covers the classification and compliance groundwork the TCO claim sits on.

Worked Example 2: The Exact-Wording Failure

Now the cautionary mirror image. A Melbourne importer brings in industrial mixing equipment and finds a TCO under the right tariff code describing, in substance: MIXERS, planetary, having a bowl capacity exceeding 150 L. Their machines are high-capacity industrial mixers — surely this is the one. The broker, on the client’s assurance, quotes the TCO.

The problem surfaces in a post-clearance compliance check eighteen months later. The imported machines are spiral mixers, not planetary mixers — a different mixing action, a different variant of the product class. The client had read “MIXERS” and stopped reading; the qualifying word “planetary” did the deciding. The goods do not match the concession’s wording, so the concession never lawfully applied.

The consequences arrive as a bundle:

• Back-duty on every entry that claimed the TCO — 5% of the customs value of eighteen months of shipments, demanded in one assessment;
• Potential penalties for false or misleading statements on the declarations, with the outcome depending heavily on whether the error looks careless or considered, and on whether the importer discovered and disclosed it voluntarily;
• Compliance attention going forward — an importer found claiming concessions loosely can expect their future entries to be looked at harder.

The lesson is not “avoid TCOs” — it is that the wording is the instrument. “Close enough” is a category error: a TCO is not a discount for goods of roughly that kind, it is a precise legal description with a binary outcome. The five-minute fix is the discipline from earlier: datasheet beside concession text, every element ticked with evidence, and where any element is genuinely arguable, get a formal ruling or written advice before claiming rather than after. A voluntary disclosure regime exists for importers who find their own errors, and using it early is dramatically cheaper than being found.

Who Benefits Most From TCOs

The substitutability test shapes exactly who the scheme serves. TCOs cluster where Australian manufacturing is absent — which means specialised, technical, low-volume goods:

• Machinery and capital equipment importers. The deepest seam. Food processing lines, packaging machinery, printing equipment, CNC and machine tools, textile machinery — Australia manufactures little of this, and the register under machinery headings is thick with concessions.
• Specialised and niche equipment. The more specific the goods, the more likely no local substitute exists and the easier a new application is to evidence. Oddly, being niche — a commercial disadvantage — is a TCO advantage.
• Medical and scientific equipment importers. Analytical instruments, laboratory systems, diagnostic and imaging equipment. Many such goods also have concessional treatment through other instruments, but TCOs remain a significant route for the categories that duty still touches.
• Manufacturers importing niche inputs. A local producer whose process depends on an imported specialty component, chemical intermediate, or material with no Australian source is precisely who the scheme was built for — removing a tax on an input nobody local sells.

Conversely, if you import consumer goods, apparel, food, or anything with healthy Australian production, the register will mostly be silent for you and applications will fail the substitutability test. Your duty-reduction toolkit is FTAs and valuation discipline — see our guides on customs valuation in Australia and reducing shipping costs on Australian imports.

Common Mistakes

Never checking the register at all. The number one mistake by an enormous margin, because you cannot lose money more silently than by not claiming a concession you did not know existed. Most importers have simply never heard of TCOs. The fix costs nothing: for every product you import regularly, confirm the tariff classification and search the register under it once, then make it a standing instruction to your broker for every new product line. An hour of checking against years of 5% is one of the most asymmetric bets in importing.

Assuming close-enough wording works. As Worked Example 2 shows, a TCO description is read literally — head noun, qualifiers, every ALL/ANY condition, every “other than” exclusion. If your goods are a variant the words do not cover, the concession does not apply, and claiming it anyway converts a duty saving into back-duty plus penalties. Match datasheet to text element by element, in writing, before the first claim.

Claiming a TCO against the wrong tariff classification. The concession lives under a specific code; your declaration must classify the goods to that code for the TCO to attach. Classification errors therefore fail twice — wrong duty treatment and an invalid concession claim. Settle classification first, honestly, with a formal tariff advice where it is genuinely arguable.

Missing revocation notices. A revoked TCO does not send you a letter. If local manufacture starts and the concession is revoked, your next shipment pays 5% and your costings are wrong until someone notices — often at margin-review time, months later. Keep a register of the TCOs you rely on and have gazette notices monitored as a standing arrangement.

Not applying when no TCO exists. A softer mistake, but real. Importers who find no matching concession often stop there, when their goods — specialised, no local substitute — are strong candidates for a new application. Roughly 150 days, an evidence-gathering exercise, and duty relief that reaches back to the lodgement date: for a recurring import paying five figures of annual duty, the arithmetic usually says apply.

Treating the TCO saving as separate from landed cost. Duty is one line in a bigger equation — freight, insurance, GST cashflow, port and broker charges. A TCO claim should feed into a single landed-cost model so you can see what each product truly costs delivered. Our walkthrough of total landed cost when importing to Australia shows where the duty line sits among the rest.

The Checklist

1. Confirm the tariff classification for each product you import regularly.
2. Search the ABF’s TCO register under each classification (and arguable neighbours).
3. For each candidate TCO, match your goods’ datasheet against every element of the wording — ALL conditions, exclusions, qualifiers.
4. Verify the concession is in force and made under the code you will declare.
5. Instruct your broker to quote the TCO number on the declaration; keep the matching evidence on file.
6. No match? Assess a new application: substitutability research, ~150-day timeline, relief operative from lodgement.
7. Log every TCO you rely on and monitor gazette notices for revocation activity.
8. Re-run the register check whenever a product’s specification or classification changes.

The TCO system is that rare thing in customs: a pure upside instrument, publicly listed, free to use, and ignored mostly because nobody looks. Look.

Frequently Asked Questions

What is a Tariff Concession Order in Australia?

A TCO is a legal instrument administered by the Australian Border Force that makes a specifically described good duty-free on import. It exists where no Australian manufacturer produces substitutable goods in the ordinary course of business — no local industry means no protection rationale, so the tariff is removed. Any importer whose goods match the concession’s wording can use it, regardless of origin country.

How do I find out if a TCO exists for my goods?

Search the ABF’s public TCO register by tariff classification code. Read every concession under your code and match your goods against the wording element by element — the description is decisive, and “close enough” does not qualify. If your goods are a variant the words do not cover, the concession does not apply.

How do I claim an existing TCO on an import?

Quote the TCO number on the import declaration against the relevant line, normally via your customs broker. Your declared tariff classification must be the same code the TCO is made under; keep the technical evidence showing your goods match the concession wording in case of a post-clearance check.

How long does a new TCO application take?

Budget roughly 150 days from lodgement to decision. The application is gazetted, local manufacturers have a 50-day objection window, and the ABF then decides. If granted, the TCO generally operates from the lodgement date, so duty paid on imports during the wait can typically be refunded.

Can a TCO be revoked, and what happens to my imports?

Yes — if an Australian manufacturer starts producing substitutable goods in the ordinary course of business, the TCO can be revoked. Duty is reinstated going forward only: entries before the revocation date keep the concession. Monitor gazette notices for revocation activity on any TCO your costings rely on.

Should I use a TCO or an FTA preference?

One or the other per line — they do not stack. A TCO is origin-independent, so it is the route when no FTA covers your origin (for example EU-made machinery) or when your goods fail rules of origin. Where both are available, the TCO is usually simpler because it removes certificates of origin and RoO analysis entirely.
