Step 1: Is it steel, aluminum or copper (or mostly made of them), a vehicle or vehicle part, or a wood product?
Section 232Section 232 applies instead of the 10%. The rate depends on the exact code and metal content, so we don't put a number on it. Ask a licensed customs broker. If the code is also on a Section 338 list (next step), the 50% is charged in addition to the 232 duty.
The rule, its date and source
Goods under Section 232 tariffs (steel, aluminum and copper articles, cars, light trucks and their parts, wood products, heavier vehicles and parts, semiconductors) do not pay the 10%. They pay their Section 232 rate instead.

Steel, aluminum and copper goods pay Section 232 tariffs: 50% on goods made of those metals, 25% on many derivative goods, 15% on some industrial machinery. The rate depends on the exact code and metal content, so we do not estimate it.

Step 2: Is its 10-digit code on a Section 338 list?
50%It pays 50% on top of the normal duty. We found no CUSMA exemption in the proclamations, so treat it as due even if your product qualifies for CUSMA. Check the exact code: the lists changed in September and change again on October 30, 2026.
The rule, its date and source
A listed set of Canadian products pays 50% (Section 338), on top of other duties. The lists go well beyond alcohol, dairy and cars: some bags, leather goods, paper, wood articles and syrups are on them. We found no CUSMA exemption in the proclamations.

Step 3: Does it qualify for CUSMA, and does the way you ship file the claim?
0%No normal duty and no 10%. Chit Chats, UPS and Purolator say they handle CUSMA claims. For Canada Post, its duty partner says a CUSMA claim removes the normal duty but not the 10% tariff, so it is not 0% there.
The rule, its date and source
Goods that enter duty-free under CUSMA (USMCA) do not pay the 10%. The claim has to be made when the parcel is cleared.

Vendor statementZonos, Canada Post's duty partner, told us in writing on October 29, 2026 that since October 22 a CUSMA claim on a Canada Post shipment under US$2,500 brings the normal duty to 0%, but does not currently remove the 10% Section 301 tariff, and it has no date for that. Its public page was contradicting itself and Zonos says it is being corrected.

Step 4: Everything else made in Canada
+10%The normal US duty for its code plus 10%. Some products, such as candles, bar soap, skin care and make-up, have a normal duty of 0%, so for them the total is 10%.
The rule, its date and source
Most goods made in Canada pay an extra 10% tariff (Section 301) on top of their normal US duty, since July 24, 2026.

Industry notes: where the answer is different
Metal goods
If you sell steel, aluminum or copper, or goods mostly made of them, Section 232 applies instead of the 301 tariff, at a rate set by the code and the metal content. Many finished goods count as “derivative” products.
Steel, aluminum and copper goods pay Section 232 tariffs: 50% on goods made of those metals, 25% on many derivative goods, 15% on some industrial machinery. The rate depends on the exact code and metal content, so we do not estimate it.

Exact words from the source
"I imposed an ad valorem duty of 50 percent on products made of those metals; an ad valorem duty of 25 percent on derivative products that tend to be predominately composed of those metals; and a temporarily-reduced ad valorem duty of 15 percent on a subset of derivative products, namely fixed industrial machinery and power equipment."

(4) wood products ... (7) semiconductor articles"
Goods on the Section 338 lists
The three proclamations are about alcohol, dairy and cars, but their product lists also take in everyday goods. Of the product codes in our duty estimator, these fall in chapters where we saw listed products: leather belts (HTS 4203.30.00.00), bags of man-made fibre (HTS 4202.92.31), maple syrup (HTS 1702.20). That is not a full list.

Food and cosmetics
Food, drinks and cosmetics need data for the FDA or another US agency. Once CBP’s new mail rules apply, that pushes a mailed parcel into formal entry, which costs more and takes a broker.
From CBP's compliance date, a mailed parcel that owes a chapter 99 tariff (like the 10% or the 50%), needs FDA or other agency data (food, cosmetics), or claims CUSMA needs formal entry. For parcels worth US$2,500 or less, CBP's voluntary Entry Type 13 test (running since September 22, 2026) is an optional electronic alternative to formal entry.

CUSMA in brief
The full paperwork, with the nine things a certification must say, is on CUSMA paperwork.
CUSMA needs no special form. A certification of origin in any format works if it has the nine required data elements. One certification can cover identical goods for up to 12 months, and records must be kept 5 years.

How do I find my product’s US tariff code?
Every rule on this page turns on your product’s code, so it’s worth getting right.
The first 6 digits of a product code (the HS code) are the same in every country. The US tariff schedule adds more digits for its own longer codes, which is where the US duty is set.
As of Oct 26, 2026 · Source: Trade Commissioner Service, Step-by-step guide to CUSMA compliance (updated August 28, 2026)
Exact words from the source
"The HS classifies all goods using HS codes that are organized by chapter (2 digits), heading (4 digits) and subheading (6 digits). HS codes are harmonized internationally up to the 6-digit level."
Your product's US duty rate comes from its code in the US tariff schedule (HTS). You can look codes up in the US International Trade Commission's database, but CBP, not you, decides the correct rate. For a firm answer on one product you can ask CBP for a binding ruling.

Exact words from the source
"CBP makes the final determination of what the correct rate of duty is, not the importer. For very specific duty information on a particular item you may request a Binding Ruling"
The US database is at hts.usitc.gov. Search it with words from your product, then read the code’s “General” duty column.
Can I get the 2025 tariffs refunded?
Only the importer of record for an entry, or the customs broker that filed it for them, can ask CBP for a refund of the 2025 IEEPA tariffs.

Our reading, not a rulingOn a parcel, the importer of record was usually whoever cleared it: the courier, consolidator or Canada Post's duty partner when you prepaid, or your customer when they paid at the door. So a refund would go to them first. Ask the company you shipped with whether it claims IEEPA refunds and passes them on.
