Who must comply with Customs Act 1901 — import declarations + duties?

The applicability test for Customs Act 1901 — import declarations + duties (ABF), computed across 35 industries, 9 business structures and 6 size bands.

Short answer: Only if

Applies only if you import goods into Australia. Whether it applies turns on a fact that no industry, structure or size settles on its own.

What the obligation is

Goods imported >$1,000 require Import Declaration (N10) + duty payment.

Section 71A of the Customs Act 1901 defines an import declaration (the N10) as the communication to the Department of Home Affairs of information about goods intended to be entered for home consumption. It is usually lodged electronically through the Integrated Cargo System, or on the approved paper forms B650 (sea or air cargo) and B374 (international mail), and covers the owner's details and identifier (ABN, ABN/CAC or CCID), transport details, and the customs value built up from invoice, freight, insurance and other costs, expressed in Australian dollars. Generally all imported goods attract customs duty and GST unless an exemption or concession applies, and some goods can be temporarily imported for up to 12 months without duty if conditions are met. An importer unsure whether a statement is accurate can attach an 'amber statement' explaining the uncertainty.

The applicability test

Applies only if you import goods into Australia. Whether it applies turns on a fact that no industry, structure or size settles on its own.

How the regulator frames it: Owners of goods imported into Australia (businesses and individuals) that are to be entered for home consumption by import declaration, and customs brokers lodging declarations on their behalf as agent of the owner.

What triggers it: Importing goods by sea, air or mail that are required to be entered, including goods held in a licensed warehouse being released for home consumption.

Jurisdiction: Commonwealth law, so the test is the same in every state and territory.

Worked examples

Each line is one run of the Rules Mate applicability engine for a single business profile, with the reason the engine gives:

Pty Ltd company in real estate agents with 6–19 employees, turnover $1M–$3M: does not apply. Requires a trigger outside this questionnaire.
Pty Ltd company in medical devices & therapeutic goods with 6–19 employees, turnover $1M–$3M: check whether it applies. applies only if you import goods into Australia.

When you need to check further

The engine shows this obligation as "check whether this applies" when a business has industry: Retail trade / E-commerce & online retail / Manufacturing or industry: Agriculture, forestry & fishing / Medical devices & therapeutic goods. It then applies only if you import goods into Australia. That fact is not something Rules Mate can infer from industry, structure or size.

What you must do, and when

When due: Before the goods can be released from customs control into home consumption; if goods are not entered within the prescribed period, a Collector may move them to a warehouse at the owner's cost and, after a further period, sell or dispose of them (s 72).
Frequency: When a triggering event occurs
Evidence to keep: Lodged import declaration and import entry advice; commercial invoice, freight and insurance documents supporting the customs value; tariff classification and origin evidence for any concession or free trade agreement claim; permits for restricted goods; duty and GST payment records; any amber statement or voluntary error notice lodged to correct a declaration.
Status: Current
Priority: High

Penalty for not complying

Maximum penalty: Making a false or misleading statement in a declaration that reduces duty is a strict liability offence with a fine of up to the greater of 60 penalty units ($21,840) and the duty shortfall (Customs Act 1901 s 243T); where no duty is lost the fine is up to 60 penalty units per false or misleading statement (s 243U). The Act also provides for infringement notices (s 243X), and the offences do not apply where a written error notice is given voluntarily before the person receives a notice under s 214AD.
