A customs hold is not random. It feels that way from the outside — your container is somewhere in Port Botany, it’s been there for five days, demurrage is accruing, and nobody has given you a clear timeline. But the holds that cost Australian importers the most money are almost always traceable to specific, avoidable causes: a wrong HS code on the import declaration, wooden packaging without an ISPM 15 stamp, a declared value that doesn’t match the commercial invoice, or goods that needed a TGA permit that wasn’t obtained before shipment.
Understanding what triggers a hold — and which authority is holding the goods — is the prerequisite for resolving it efficiently and avoiding it in future. Australian imports are subject to two separate regulatory frameworks at the border, administered by two different agencies, each with their own grounds, timelines, and resolution processes.
The Two Authorities: ABF and DAFF
Australian imports at the border are assessed by:
Australian Border Force (ABF) — administers the Customs Act 1901. Responsible for customs duty and GST collection, import declaration accuracy, prohibited imports, and border security. ABF holds are triggered by documentation issues, duty assessment disputes, misclassification, prohibited goods, or risk-targeted examination.
Department of Agriculture, Fisheries and Forestry (DAFF) — administers the Biosecurity Act 2015. Responsible for preventing biosecurity risks — pests, diseases, and invasive species — from entering Australia through imported goods or their packaging. DAFF holds are triggered by biosecurity risk in the goods themselves, non-compliant wooden packaging, or goods in regulated categories (plant products, animal products, organic material).
A single shipment can face holds from both authorities simultaneously — ABF holds on the declaration while DAFF holds on the packaging. Each resolves independently and the goods cannot be released until both clear.
The Most Common Causes of ABF Customs Holds
1. Incorrect or Incomplete Import Declaration
The import declaration (lodged by your customs broker via the Integrated Cargo System) is the primary document ABF reviews. Common errors that trigger a hold:
- Incorrect HS code — causing the wrong duty rate to be applied or triggering classification review
- Missing or incorrect tariff concession — claiming an FTA rate without a valid Certificate of Origin on file
- Incorrect description of goods — description doesn’t match what’s in the container
- Missing required fields — incomplete declaration is rejected and must be corrected before processing
HS code misclassification is particularly consequential. If ABF reclassifies your goods to a higher duty rate, you owe the difference plus potential penalties. If you’ve claimed an FTA 0% rate but the goods don’t qualify (wrong CoO issuing body, CoO issued after loading, goods not meeting Rules of Origin), you owe MFN duty on the entire consignment.
2. Underdeclared Customs Value
Australia uses the CIF (Cost, Insurance, Freight) customs value method. If your import declaration shows a customs value that doesn’t match the commercial invoice, or if the invoice appears artificially low relative to market value, ABF will query it. Common scenarios:
- Invoice in a non-AUD currency with an incorrect conversion rate
- Invoice showing FOB value but freight not included (CIF is required)
- Related-party transactions where the invoice price is below market value
- Proforma invoices used instead of commercial invoices
Value queries typically result in a documentation hold — ABF requests supporting evidence (bank transfers, supplier pricelists, comparable market data). Resolution takes 3–10 business days.
3. Prohibited or Restricted Goods
Certain goods require permits or are prohibited entirely:
- Therapeutic goods (TGA): Medicines, medical devices, and therapeutic products require TGA import permits or ARTG registration before importation. Goods arriving without permits are held and may be seized.
- ACCC product safety: Products subject to Australian mandatory safety standards that don’t comply (electrical goods, children’s products, personal protective equipment) may be held for assessment.
- DFAT-regulated goods: Dual-use goods, defence items, and goods subject to sanctions require DFAT permits.
- Prohibited imports schedule: Under the Customs Act, certain goods are absolutely prohibited — narcotics, certain weapons, child exploitation material, counterfeit currency.
4. Risk Targeting by ABF’s Cargo Targeting Branch
ABF uses data analytics and risk profiling to select consignments for examination. Factors that increase targeting probability include:
- New importer with no declared history
- Goods in high-risk categories (electronics, pharmaceuticals, certain textiles)
- Origin countries flagged for specific risk profiles
- Consignments with inconsistencies between the manifest and the declaration
- Previous compliance issues on the importer’s record
Risk targeting is not fully transparent — ABF does not publish its selection criteria. What is known is that importers with a consistent record of accurate, compliant declarations have lower examination rates over time. Compliance builds a track record; that track record reduces targeting.
The Most Common Causes of DAFF Biosecurity Holds
1. Non-Compliant Wooden Packaging (ISPM 15)
This is the single most common cause of DAFF holds for general cargo. ISPM 15 requires all wooden packaging material — pallets, crates, dunnage, wooden cable spools — to be heat-treated or fumigated and marked with the official ISPM 15 stamp (the wheat sheaf mark with treatment code and country code).
DAFF inspectors check wooden packaging on arrival. If packaging is non-compliant:
- Goods are detained pending treatment
- Treatment options: fumigation (methyl bromide or phosphine) or heat treatment — conducted by DAFF-approved providers at the importer’s cost
- Treatment cost: typically AUD 200–800 per container depending on treatment type and volume
- Re-inspection after treatment: 2–5 business days additional
- Total delay from ISPM 15 non-compliance: 5–12 business days minimum
Prevention: require all Chinese (and other origin) suppliers to use ISPM 15 marked pallets and packaging. Confirm with packing photos before loading. Australia’s biosecurity import conditions apply to the packaging of all goods, not just the goods themselves.
2. Goods with Biosecurity Risk
Certain product categories trigger mandatory DAFF inspection regardless of documentation:
- Plant products for human consumption (seeds, dried herbs, herbal supplements)
- Animal products (leather, wool, animal-derived ingredients)
- Untreated timber and wood products
- Soil and growing media
- Live plants and plant material
For these categories, DAFF BICON (Biosecurity Import Conditions database) specifies the import conditions — permit requirements, treatment requirements, and documentation. Importing without checking BICON first is the most predictable way to generate a DAFF hold.
3. Goods Not Meeting Import Conditions
Even for goods that are legally importable, specific import conditions may require documentation that wasn’t obtained — phytosanitary certificates from the origin country’s national plant protection authority, health certificates for animal products, or treatment certificates. Missing documentation triggers a DAFF hold while the documentation is sourced (if possible) or the goods are refused entry.
What Happens to Your Goods During a Hold
Goods don’t stop costing money during a customs hold. The financial consequences:
- Container demurrage: The shipping line’s free-time period (typically 5–10 days after vessel arrival) continues to count during any hold. Once free time expires, daily demurrage charges apply — AUD 80–200 per day per TEU, escalating on a tiered schedule. On a 14-day hold after free time, this is AUD 1,120–2,800 per container.
- Port storage: The terminal charges daily storage fees for containers in the yard. AUD 30–80 per day per TEU typically.
- Treatment costs (DAFF): Fumigation or heat treatment at the importer’s cost. AUD 200–800 per container.
- Customs broker additional fees: Managing a hold involves additional correspondence, document gathering, and liaison with ABF or DAFF. Brokers charge for this time.
- Downstream costs: Production delays, stockout losses, missed delivery deadlines to customers.
The importer is responsible for all these costs, regardless of whether the hold was caused by the supplier, the freight forwarder, or the customs broker. Responsibility for avoiding holds sits with the party with the most control over the inputs — typically the importer, through their supplier instructions and documentation management.
How to Reduce Hold Risk
The controllable variables that most directly affect hold risk:
| Risk Factor | Control Action |
|---|---|
| Incorrect HS code | Obtain a classification ruling from ABF or a licensed customs broker before first import; review at each new product introduction |
| Customs value understatement | Use the correct CIF value on all declarations; match invoice currency and conversion rates; brief suppliers on Australian invoicing requirements |
| Missing Certificate of Origin for FTA rate | Brief supplier to prepare CoO before loading; confirm CoO is from the correct issuing body (CCPIT/CIQ for China) |
| ISPM 15 non-compliant packaging | Specify ISPM 15 marked pallets in every purchase order; request packing photos confirming stamps before booking the vessel |
| Missing TGA / DAFF permits | Check BICON and TGA requirements before placing any order for regulated goods; obtain permits before shipment |
| Inconsistent invoice vs packing list vs bill of lading | Require all shipping documents to be consistent before accepting them from the supplier; check quantities, descriptions, and values before the vessel loads |
Spend a week sitting with customs brokers in the eastern-state ports and a pattern in delayed shipments becomes hard to ignore. The shipments that get held are not, in the main, the obviously risky ones. The obviously risky ones get pre-screened by experienced brokers who flag the issues before the cargo moves. The shipments that get held are the ones that looked routine on paper and turned out to have a small documentation inconsistency that took several days to resolve — a commercial invoice value that did not match the packing list, a country-of-origin field that conflicted with the certificate, a tariff classification that the import broker had treated as obvious but the ABF officer was unwilling to accept. None of these incidents look serious in isolation. Each individual document review takes hours, not weeks. But the cumulative effect across a portfolio of importers shapes which businesses pay storage fees and which do not. The customs delay statistics published by the regulator do not capture this. The brokers who deal with the consequences daily can describe the pattern in detail. Anyone planning a shipment into Australia would do well to ask their broker for that detail before the cargo leaves origin.
Frequently Asked Questions
Why would Australian customs hold my shipment?
ABF holds: incorrect import declaration, underdeclared value, wrong HS code, prohibited/restricted goods, or risk targeting. DAFF holds: biosecurity risk in the goods or packaging (most commonly ISPM 15 non-compliant wooden packaging), or goods in regulated categories without required documentation.
What happens to my goods during a hold?
Goods sit in the port terminal or bonded warehouse. Container demurrage (AUD 80–200/day per TEU after free time), port storage fees, and any treatment costs accrue at the importer’s expense. Holds do not pause the shipping line’s free-time clock.
How long does a customs examination take?
ABF documentary review: 1–3 business days. Physical examination: 3–7 business days. DAFF inspection: same-day to 10+ days if treatment (fumigation/heat treatment) is required plus re-inspection. Document-related holds are indeterminate — resolved when the documentation issue is fixed.
What is ISPM 15 and why does it cause Australian customs delays?
ISPM 15 is the international standard requiring wooden packaging (pallets, crates) to be heat-treated or fumigated and stamped. DAFF enforces it strictly. Non-compliant packaging triggers a hold for treatment (AUD 200–800 per container) plus re-inspection — adding 5–12 business days minimum.
Can I reduce examination risk?
Yes: correct HS codes, accurate CIF customs values, complete documentation, ISPM 15 compliant packaging on every shipment, and all required permits obtained before shipment. Importers with a consistent compliance record face lower ABF targeting over time.
Avoiding Customs Delays on Australian Imports
Understanding import duty and GST is the foundation for accurate declarations. Australia’s biosecurity import conditions govern what DAFF requires across all product categories — checking BICON before ordering is the most reliable way to avoid biosecurity holds.
