The additional 50% duty on newly covered Canadian goods does not replace every other charge on an import entry. Trump's October 23 proclamation, published October 30, expressly says the revised duty applies alongside applicable Section 232 duties. CBP's October 29 instructions preserve applicable antidumping and countervailing duties and other taxes, fees, exactions and charges.
A headline rate therefore cannot establish a shipment's total duty bill, much less a shopper's final price. The records identify what can apply; they do not provide the values and classifications needed to price an individual entry. No shipment-level invoice or retail pass-through estimate is established here.
Aircraft treatment has conditions
Annex I, Part B, excludes qualifying civil aircraft and aircraft parts meeting HTSUS General Note 6. CBP describes heading 9903.03.16 as carrying 0% additional duty for qualifying civil-aircraft goods, including engines, parts, components and ground flight simulators. Its description excludes military and unmanned aircraft.
Those conditions matter. The aircraft treatment does not support a claim that any aircraft-related shipment, or any product with an aviation use, automatically avoids the charge.
Chapter 98 is not a universal escape
CBP requires a proper Chapter 98 claim and its agreement for the general exception. The bulletin excludes subchapter XXIII, subheadings 9802.00.40, 9802.00.50 and 9802.00.60, and heading 9802.00.80 from that general exception.
For the three named subheadings, the additional duty applies to the described repairs, alterations or processing value. For heading 9802.00.80, it applies to the assembled article's value less the described U.S. products' cost or value. Those are different bases; treating all of them as a full exemption would misstate the instructions.
The bulletin also addresses foreign-trade zones: affected goods must enter under privileged foreign status unless eligible for domestic status, and the duty applies on consumption entry under the applicable classification. It says the additional duties under headings 9903.03.12 through 9903.03.14 are eligible for drawback.
A category count cannot price an entry
The amendment adds 100 classifications and removes 22. Those counts reveal a change in coverage, not the total amount due from an importer. The value, origin, classification, other duties and valid exceptions determine the next questions.
The practical consequence is a rule change businesses must apply to actual entries. A claim about what a family pays requires evidence beyond a tariff headline.
