Canadian-made goods entering the United States and U.S.-made goods entering Canada have separate product lists, dates, and duties. A rule in one direction does not apply in the other.
The effective dates listed here have passed. Recheck the linked customs sources for amendments, relief, transition, refunds, or a later end date before filing.
This separation is an editorial interpretation of the existing official-source artifact; it is not a new freshness check.
Official CBP guidance in the local snapshot reports the Section 338 duties as applying to covered Canadian goods entered on or after August 22, 2026.
The United States Surtax Order (2026) applies schedule-specific surtaxes to listed U.S.-origin goods beginning September 8, 2026, or registration if later, subject to its exceptions.
The operative Order assigns rates by Schedules 1, 2, and 3 to listed goods that qualify as U.S.-origin under the marking rules. It is not a blanket Canadian rate: exceptions, remission or relief, and other duty or tax layers require separate review. CBSA Notice 26-23 states that the Order does not cumulate with the Steel Derivative Goods Surtax Order and limits the in-transit exception to goods already in transit under carrier control, with proof required.
Category names are navigation aids only. Exact tariff lines in each annex control.
Specified wine, beer, spirits, and related products in Proclamation 11046 Annex II.
Specified milk, cheese, butter, and other dairy lines in Proclamation 11047 Annex II.
Specified passenger vehicles and auto parts in Proclamation 11048 Annex II.
Specified meat, produce, prepared foods, and related goods.
Specified lumber, paper, plastics, fertilizers, chemicals, and pharmaceuticals.
Specified tools, packaging, cosmetics, jewellery, and other goods.
The original U.S. summary identified energy, potash, goods already subject to Section 232, and certain fish and critical-mineral goods as outside this action. Treat every exclusion as product- and entry-specific; existing steel, aluminum, auto, alcohol, dairy, CUSMA, Section 301, and AD/CVD layers can move separately.
Dates below describe the represented snapshot, not a freshness claim.
| Date | Type | Direction | Record | Status |
|---|---|---|---|---|
| 2026-07-23 | Published | Canada origin → U.S. | Proclamations 11046, 11047, and 11048 with separate Annex II scopes | Original official actions |
| 2026-08-22 12:01 a.m. ET | Amended effective instant | Canada origin → U.S. | Proclamation 11056 plus CBP implementation guidance | Represented as operative for covered entries |
| 2026-09-04 | Order made | U.S. origin → Canada | P.C. 2026-0785 · United States Surtax Order (2026) | Sections 1–2 and Schedules 1–3 define rates, scope, and exceptions |

Record destination, manufacturing facts, importer, and origin basis; shipment country is not enough.
Match the 10-digit classification to the correct operative annex or Canadian tariff item.
Keep ordinary duty, Section 338, Section 301/232, AD/CVD, Canadian surtax, and fees distinct.
Retain the instrument, customs notice, entry date, exclusions, transition terms, and broker confirmation.
The local official-source snapshot includes CBP guidance stating that the additional duties apply to covered Canadian goods entered on or after August 22, 2026. Exact product, annex, origin, entry timing, exclusions, Chapter 99 reporting, and later amendments still require verification.
Proclamation 11056 amended the effective timing of the three original July proclamations. It did not replace their separate product annexes. Canada’s maintained list separately states that counter-tariffs on listed U.S.-origin goods took effect at 12:01 a.m. on September 8, 2026.
No. The original U.S. action said covered goods remained subject regardless of USMCA origin status. CUSMA can affect other layers, so qualification and Section 338 annex coverage remain separate tests.
No. The calculator models represented duties for goods entering the United States. It is not a Canadian tax engine and does not calculate the counter-tariffs on goods entering Canada.
Reference information only—not customs, legal, tax, classification, or filing advice. This editorial revision does not replace the artifact’s separate official-source verification time.
