Know with certainty how your goods are classified, and what duty you will pay

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.
