Where does the 554-line list come from?

White House Annex II PDFs for proclamations 11046 (alcohol), 11047 (dairy), and 11048 (motor vehicles). Descriptions and ordinary rates are from USITC HTSUS 2026 Revision 16.

Is Canada’s dollar-for-dollar list in TariffScope?

No. The CBSA T2026 file is the ordinary schedule, not retaliation coverage. Extra CA duty stays pending until Finance publishes HS items.

Section 338 tariff list — Canada origin

The list that matters for US inbound extra duty is Annex II, not a keyword blog post. Canada’s matching list is still unpublished.

US extra duty (Canadian origin): 554 8-digit HTS lines, effective 22 August 2026. Filing headings in Chapter 99 include 9903.03.12 (alcohol), 9903.03.13 (dairy), 9903.03.14 (motor-vehicle annex). Rate: 50% additional.

The motor-vehicle annex is the broad one. Alcohol is not only drinks (hockey equipment is cited there). Dairy is not “all dairy” — heading 0406 cheese is not on that annex.

Look up a line in the scanner. Ordinary HTSUS text comes from USITC 2026 Revision 16 (14,957 8-digit index). That schedule is not the 50% list.

Canada inbound (US origin)

Counter-tariffs were announced for about 8 September 2026. Until Finance / CBSA publish the HS items, TariffScope shows pending for extra CA duty and will load the official list the day it exists. The T2026 Access file we ingested is descriptions + MFN/UST — not retaliation.
