Know exactly how your goods should be classified, and what Customs duty applies

When the tariff heading is arguable, a formal determination settles it

Tariff classification is rarely black and white. For many products there are two or more competing headings that could apply, and the decision is often open to interpretation. That’s why importers and Customs so often disagree on how goods should be classified, and why the same product can end up dutied differently across an industry.


A Tariff Determination removes that uncertainty. It’s a legal, binding ruling issued in writing by the Commissioner that fixes how your goods are classified and, in turn, the rate of duty you pay. We research the product, build the motivation, and secure the ruling, so you’re operating from certainty instead of assumption.

A determination is only as strong as the case behind it

The ruling you get back depends almost entirely on how well the application is motivated. Two things make the difference: thorough research and understanding of the product, and deep, practical command of the classification rules. Get either wrong and a favourable outcome can just as easily come back negative.

This is exactly where experience earns its keep. We know how Customs approaches classification, what the motivation needs to contain, and how to argue for the heading that’s correct for your goods, so the determination lands in your favour rather than against you.

Why correct classification matters to the business

Correct classification is about a level playing field. You need to know you’re paying the same duty as your competitors on competing products, not more. A determination delivers that by fixing how goods are classified uniformly across the industry.

It also protects you going forward. A ruling secured before you import removes the risk of reclassification, unexpected duties and extra costs landing after the fact, and gives you the cost certainty to price your products accurately from the start.

When to get a determination

A Tariff Determination works in two situations. Most people only know about the first. The second is where the real peace of mind is, and it’s the one that gets overlooked.

After you've imported: settle a classification that's in question

If you’re already bringing goods in and you’re not certain the heading is right, or Customs has raised a query, a determination fixes it in writing. You stop guessing, you stop carrying the risk, and you have a binding ruling to stand on.

Before you import: get certainty in advance (Intended Importation Ruling)

This is the one few importers realise they can use. Before you commit to a product, you can secure a determination on how it will be classified and what duty it will attract, upfront. No nasty surprises after the shipment lands. No reclassification months later. No unexpected duty wrecking your margin. You know your cost before you buy, so you can price with confidence and plan properly.

For anyone bringing in a new product line, this is as close to certainty as importing gets, and it’s remarkable how few businesses know it’s available to them.

Frequently asked questions

A Tariff Determination is a formal decision issued by the Commissioner for Customs and Excise confirming the correct tariff classification of specified goods.

It provides certainty regarding future imports and can be used to support refund claims where goods were previously classified incorrectly.

Yes. You can formally apply for a Tariff Determination, which is a legally binding decision issued by the Commissioner confirming the correct classification of your goods and the duty rate that applies.

It also promotes consistent classification across the industry, so you pay the correct duty, no more and no less.

Every product can only have one correct tariff heading. However, identifying that heading is not always straightforward.

Tariff classification is governed by the General Rules for the Interpretation of the Harmonized System, the wording of the headings, legal notes and the Harmonized System Explanatory Notes.

As a result, different importers may sometimes classify identical or similar goods under different headings until the correct classification is determined.

Yes. Customs may take a different view of the correct tariff classification at any time.

This is why importers should periodically review their classifications, particularly where products have changed, legislation has been amended or new Customs interpretations have developed.

A Tariff Determination is often worthwhile where the classification is uncertain or commercially significant.

It can provide an official decision before importing a new product or settle uncertainty over goods that are already being imported.

It provides an official classification decision by the Commissioner, giving greater certainty regarding future imports and the duty rate that applies.
Classification is based on the Harmonized System, legal notes, explanatory notes and the product’s technical characteristics, not simply the name or description used by the supplier.
You may be able to request that the decision be reconsidered via an Internal Administrative Appeal (IAA), an Alternate Dispute Resolution (ADR), or pursue legal remedies through the High Court. The appropriate route will depend on the circumstances and should be assessed carefully.
