Below is every change Upstream has on the record for it, with the rate as published, the date it takes effect, and the notice it came from.

CUSMA-qualifying Canadian mobile industrial and agricultural equipment and residential HVAC are charged on non-US content only, with a 15% floor.

Rate: 25% — on the non-US content, and never less than 15% on the article; a temporary structure through December 31, 2027

For the goods listed in its Annex I-A, Section 232 duty is charged on the full customs value of the article rather than on its metal content alone.

Rate: 50% — on the full customs value; the goods in Annex I-B carry a 25% baseline

The metal-content basis survives for goods classified in chapters 72, 73, 74 and 76. Which annex a specific code sits in decides the basis, and we do not read annex membership for you — that is the code on your invoice against the annex.

Derivative goods outside chapters 72, 73, 74 and 76 that do not contain enough steel, aluminium or copper are not subject to the duty at all.

Rate: no rate set — an exclusion, not a rate; the thresholds are in Annex IV of the proclamation

The IEEPA border duty on Canadian goods — 35% on anything not qualifying for CUSMA — is no longer in effect and is no longer collected.

Rate: no rate set — the order ends the duty; it does not set a rate. Section 232 and Section 301 duties are unaffected.

CBP's entry-filing instruction is CSMS #67834313 of February 22, 2026, which states the duties are not collected for goods entered on or after 12:00 a.m. eastern time on February 24, 2026, and that Section 232 duties are unaffected. We have not found any order reimposing a Canada-specific IEEPA duty since.

Hundreds of goods outside the metal chapters — machinery, appliances, furniture, plastics, base-metal articles — became Section 232 derivative articles, charged on their metal content.

Rate: 50% — on the declared value of the steel or aluminium content

Whether a specific code is on the list is decided by HTS chapter 99, U.S. notes 16 and 19, not by the chapter its goods sit in. Check the code on your customs invoice against that list, or ask your broker. We do not assign codes.

Rates are quoted as published, in the notice's own words. Upstream does not assign HTS codes and does not rule on whether your goods qualify for CUSMA preference — your customs invoice and your broker do that.

CUSMA preference matters here. For the equipment in Annex I-C, a qualifying Canadian good is charged 25% on its non-US content with a 15% floor rather than the flat rate other countries pay — and a derivative good without enough metal content is not charged at all.
