HS codes explained

The code decides the duty rate, which trade agreement applies, whether a surtax reaches you and which permits you need. Everything else follows from getting it right.

What the digits mean

Take 9403.40.00.10, wooden kitchen cabinets, and read it left to right. Each pair of digits narrows the one before it.

The first six digits are the same everywhere. Canada, the United States, China and around two hundred other countries all use the same chapters, headings and subheadings, because they come from the World Customs Organization's Harmonized System. Digits seven onward are each country's own. So your supplier's six-digit code is a genuinely useful starting point, and their eight or ten digit code is not, because it is their country's tariff and not Canada's.

Canada and the United States are different past six digits

Canada calls the eight-digit line a tariff item and adds two more for statistics. The United States calls its schedule the HTS and carries its own eight and ten digit lines with its own rates. The same goods will have the same first six digits in both and different endings.

That is why we keep two separate lookups rather than pretending one answer serves both.

Classification is yours, legally

CBSA puts the responsibility for classification on the importer, not on the tool you used and not on your supplier. A supplier's code is a hint. Getting it wrong is expensive in both directions: too high and you overpay quietly for years, too low and you owe the difference plus interest when it is found.

If the goods are valuable or you will import them repeatedly, an advance ruling from CBSA settles it in writing and binds them. For a one-off shipment, a broker reading the actual goods is usually enough.

How to search well

We band every answer, and we hold the band back when we should. A result marked "strong" means the words you typed are distinctive and were all found. If you type a category word, or a word we have never seen, we will not claim certainty, and we tell you which word stopped us. Being confidently wrong about a tariff code is the failure mode that costs money, so we would rather look unsure.

The chapters, all of them

If you do not know the words to type, start from the chapter.

A search over CBSA's published descriptions, not a customs ruling. Classification is the importer's responsibility. Confirm with a licensed customs broker, or get an advance ruling from CBSA, before you rely on a code.
