The Australian Border Force (ABF) conducts compliance activity before, at and after the border, and incorrect or misleading import declarations can lead to financial penalties or legal action. Errors in tariff classification or customs value can result in duty and tax adjustments as well as enforcement action. With more than 25 years helping Australian importers navigate customs compliance, Magellan Logistics works alongside businesses to get declarations right from the outset.
This guide covers the most common customs declaration errors Australian importers make, the ABF penalty structure, and the practical steps that help you stay compliant, including when early action can reduce your exposure to customs penalties in Australia.
What Are the Penalties for Incorrect Customs Declarations in Australia?
Most importers assume ABF enforcement is rare. In practice, the ABF actively monitors the accuracy of import declarations through its Compliance Monitoring Program, and the penalty tiers for customs declaration errors are steeper than many businesses realise.
How the ABF Responds to Non-Compliance
The ABF response depends on the legislation, circumstances and seriousness of the non-compliance. Outcomes can include correcting the declaration and paying short-paid duty or tax, an infringement notice, or prosecution in serious cases. These are possible enforcement outcomes rather than a fixed three-tier sequence.
Penalty amounts are calculated using the Commonwealth penalty unit system under Section 4AA of the Crimes Act 1914, as published on the Federal Register of Legislation. The penalty unit value is indexed periodically, so the dollar figure that applies to any given offence depends on the date the offence was committed. Under Section 4B of the Crimes Act 1914, a court can impose a fine on a body corporate of up to five times the maximum that applies to an individual for the same offence, which is why corporate exposure is considerably higher. For the current penalty unit value, refer to the Federal Register of Legislation or speak to a licensed customs broker.
The Five-Year Record-Keeping Requirement
Section 240 of the Customs Act 1901 requires owners of imported goods to retain relevant commercial documents for five years. Those records support later verification of matters such as classification, valuation and duty liability, so accurate record-keeping is essential.
What Mistakes Trigger Customs Declaration Penalties?
Understanding what ABF looks for is the first step in avoiding an incorrect import declaration in Australia.
Tariff Classification and HS Code Errors
Incorrect HS code classification is the most common trigger for customs penalties in Australia. Assigning the wrong HS code can result in a lower duty rate being applied when a higher rate should apply, which ABF treats as under-payment of duty. Importantly, the ABF has stated that penalties may apply for incorrect classification, even where there is no difference in the customs duty paid.
ABF offers tariff advices (advance rulings), which lock in a tariff classification before goods are imported. Requesting a tariff advice is one of the most effective ways to avoid this category of customs declaration error, particularly for high-volume or high-value goods.
Customs Valuation Under-Declaration
Customs value must reflect the full transaction value, including any assists (materials or services provided free of charge), royalties, and adjustments for related-party transactions. Declaring a lower invoice value to reduce duty exposure is a common trigger for formal ABF review.
Does the De Minimis Threshold Protect You?
For most goods valued at AUD$1,000 or less, duties, taxes and charges are generally not collected at the border. Separate low-value-goods GST rules may still require GST to be collected at the point of sale for consumer purchases.
The Alcohol and Tobacco Exception
The de minimis exemption does not apply to alcohol or tobacco. These goods attract duty and tax regardless of their customs value. This exception catches importers who assume the threshold applies universally.
An import processing charge also applies to consignments valued above AUD$1,000. For electronic declarations, the charge increases once the consignment value reaches AUD$10,000 or more, and documentary lodgements attract higher charges again. These charges apply alongside any duties and taxes payable.
Can Voluntary Disclosure Reduce Your Penalty Exposure?
If your business identifies an error in a previously lodged customs declaration, acting before ABF contacts you can materially affect the outcome.
A voluntary disclosure is made through a written error notice that fully, truthfully and voluntarily identifies the affected declaration and the nature of the error. When the statutory conditions are met, it provides protection from the false or misleading statement offences in sections 243T and 243U of the Customs Act 1901. It does not remove liability for short-paid duty or tax, which must still be paid.
This is one of the most effective tools for managing customs penalty exposure, yet few importers are aware it exists. Magellan Logistics’ licensed customs broker team can assess whether voluntary disclosure is appropriate for your situation and help prepare a submission.

Customs Declaration Compliance Checklist for Australian Importers
Use this checklist before lodging every import declaration to reduce your risk of customs declaration errors in Australia:
- Confirm HS code classification using ABF tariff schedules or secure a tariff advice.
- Verify customs value: transaction value plus any assists, royalties, and related-party adjustments.
- Check whether goods are subject to anti-dumping measures, biosecurity restrictions, or prohibited-import conditions.
- Confirm whether the low-value border concession applies, and note the separate point-of-sale GST rules and the tobacco and alcohol exclusions.
- Retain commercial invoice, packing list, bill of lading or air waybill, and any relevant permits for a minimum of five years.
- If an error is discovered post-lodgement, consider voluntary disclosure under ss.243T/243U of the Customs Act 1901 before ABF makes contact.
Note: biosecurity screening by the Department of Agriculture, Fisheries and Forestry (DAFF) operates separately from the ABF customs entry process and carries its own charge regime. For guidance on the lodgement process itself, refer to Magellan’s step-by-step customs entry guide.
