Illustration for the guide: HS Codes & Tariff Classification

Key takeaways

  • Your tariff classification decides duty rate, restrictions and FTA eligibility.
  • The first 6 digits are global; Australia extends to 8–10 digits in the Working Tariff.
  • Uncertain? A binding Tariff Advice from the ABF protects you from reassessment.

HS Codes & Tariff Classification

Every product crossing the Australian border is classified under a single code. That code — your tariff classification — decides your duty rate, whether restrictions apply, whether an FTA preference is available, and what statistics are recorded. Getting it wrong means overpaying duty, or worse, underpaying and facing reassessment and penalties.

How HS codes work

The Harmonized System is a global standard maintained by the World Customs Organization:

Digits Meaning Example
First 2 Chapter (broad category) 61 — knitted clothing
First 4 Heading 6109 — T-shirts and singlets
First 6 International subheading 610910 — of cotton
8 digits Australian tariff item adds national duty distinctions
10 digits Full statistical code adds statistical detail for the declaration

The first six digits are identical worldwide; Australia extends to 8–10 digits in the Working Tariff published by the ABF.

How to find your code

  1. Start with the product's material, function and form — classification follows objective characteristics, not marketing names.
  2. Search the Working Tariff on abf.gov.au by keyword or browse chapters.
  3. Read the chapter and section notes — they contain binding inclusion/exclusion rules that frequently override intuition.
  4. Compare candidate headings and apply the General Interpretive Rules (GIRs) in order.
  5. When genuinely uncertain, apply to the ABF for a Tariff Advice — a binding ruling that protects you from later reassessment.

Why the code matters

  • Duty rate: each tariff line carries its own rate — 0%, 5%, or specific rates for textiles, footwear, vehicles, alcohol and tobacco.
  • FTA eligibility: preferential rates under ChAFTA, CPTPP and other agreements are set per tariff line.
  • Restrictions: some codes flag prohibited/restricted goods or permit requirements.
  • GST is unaffected — always 10% of VoTI regardless of classification.

Common classification mistakes

  • Classifying by what the product is called instead of what it is (a "gift set" is usually classified by its components or essential character).
  • Copying the supplier's HS code without checking — the first six digits travel internationally, but the Australian tariff item may differ from the export country's code.
  • Ignoring composite goods rules for kits and sets.
  • Assuming a product that was duty-free last year still is — tariff lines and concession orders change.

Practical tip: ask your supplier for the six-digit HS code on the commercial invoice, then confirm the full Australian tariff item yourself or through your broker before the first shipment.

Frequently asked questions

How do I find the HS code for my product?

Search the Working Tariff on abf.gov.au by keyword, starting from the product's material and function. Read the chapter notes, compare candidate headings, and apply the General Interpretive Rules. For genuinely difficult cases, apply for a binding Tariff Advice from the ABF.

Can I just use the HS code my supplier gives me?

Use it as a starting point only. The first six digits are international, but Australia extends codes to 8–10 digits and your supplier's export code may differ from the correct Australian tariff item — which determines your duty rate and any restrictions.

What happens if I classify goods incorrectly?

If you underpay duty, the ABF can reassess the declaration, recover the shortfall and apply penalties — and audit several years of past entries. Overpaying means money lost unless you claim a refund within the allowed window.
