HS Code Classification in Canada
Every product entering Canada must be declared under a 10-digit tariff classification. That code — not your product's name — sets the duty rate, decides CUSMA eligibility, and defines your audit exposure.
Classification is the highest-leverage compliance decision an importer makes — and it is made on every single entry. We make it correctly, and we document why.

Applied General Rules of Interpretation, checked rulings, documented reasoning — not keyword search in a lookup tool.

What a Wrong Code Actually Costs
How the 10 digits work — and why U.S. codes fail
The first six digits come from the international Harmonized System, shared worldwide. Canada adds four more to set national duty rates and statistical detail. Copying a U.S. HTS code from your supplier's paperwork fails precisely here: the first six digits may match, but the last four — the ones that set your Canadian duty rate — frequently do not.
Correct classification follows the tariff's General Rules of Interpretation in order — headings and legal notes first, essential character for composite goods, most-specific-description over general — plus a check of current CBSA rulings for your product family.
Too expensive, too cheap — both cost you
Classify into a higher-duty item and you overpay on every shipment, silently, often for years — nobody sends a letter about duties you didn't need to pay.
Classify too low and the exposure reverses: CBSA can reassess up to four years of entries with interest, layer AMPS penalties on top, and a wrong code also invalidates CUSMA claims built on it. Read what a CBSA audit involves before the letter arrives.
For genuinely ambiguous products, a CBSA advance ruling locks the classification in writing before you import — certainty instead of hope. Classification review is built into our brokerage fees.

One Wrong Digit Compounds
A misclassified product doesn't fail once — it fails on every entry: overpaid duty or a four-year reassessment, broken CUSMA claims, missed permits for regulated goods, and AMPS penalties stacked on top.
The fix is a process, not luck: verified codes, documented reasoning, and a database your future entries reuse.
Frequently Asked Questions
My supplier already puts an HS code on the invoice. Isn't that enough?
Treat it as a starting hint, not an answer. Suppliers classify for their own export rules, usually at six digits, and carry no liability for your Canadian entry — you do.
How do I get certainty on a genuinely hard product?
A CBSA advance ruling: a written, binding classification decision issued before you import. It takes preparation and time, but for a high-volume or high-duty product it converts risk into certainty.
We've been using the same codes for years. Is that a problem?
It's a question worth answering deliberately. Products change, tariff notes change, and rulings accumulate. A periodic review either confirms you're fine — or catches an error while it's still cheap.
