These are the additional duties layered on since 2025, above the normal (MFN) baseline — assuming the importer passes the full cost to you, which is the upper bound. The 10% global Section 122 tariff expired at 12:01 a.m. EDT on July 24, 2026 at its 150-day statutory limit, and was replaced the same minute by Section 301 forced-labor duties — 12.5% on most economies, 10% on those with a forced-labor import ban — under the July 23, 2026 presidential memorandum. China's ~35% combined duties and the Section 232 sector tariffs (autos 25%, steel/aluminum/copper 25–50%) were untouched, so most landed costs did not fall. Since July 31, 2026 there is one more layer: a 100% Section 232 duty on patented brand-name medicine and its ingredients, phasing in company by company through September 29, 2026. And since just after midnight ET on August 22, 2026 there is a Canada layer: 50% Section 338 duties on roughly US$20 billion of listed Canadian goods, applying whether or not the product qualifies under USMCA, after the two governments failed to sign the deal Trump had announced four days earlier.

❓ Frequently Asked Questions
Who actually pays tariffs?
The importer of record pays the duty when goods clear US customs. How much of that reaches your receipt varies by product and retailer — this calculator assumes the full duty is passed through to you, which is the upper bound.
What changed on July 24, 2026?
The 10% global tariff (Section 122) hit its 150-day statutory limit and expired at 12:01 a.m. EDT on July 24, 2026. It did not disappear into nothing: a July 23, 2026 presidential memorandum brought Section 301 forced-labor duties into effect the same minute — 12.5% on the 46 economies that have neither banned forced-labor imports nor committed to, and 10% on those that have, covering about 60 economies in all. Sector tariffs on autos, steel, aluminum and copper (Section 232) and China's legacy Section 301 duties were unaffected, so for most importers landed costs did not actually fall.
Is there a 100% tariff on medicine now?
On patented brand-name drugs, yes — in stages. The Section 232 proclamation signed April 2, 2026 sets a 100% duty on patented pharmaceuticals and pharmaceutical ingredients, effective July 31, 2026 for the companies listed in the proclamation's Annex III and September 29, 2026 for everyone else. Generics, biosimilars, US-origin product, orphan drugs, nuclear medicines, plasma-derived therapies, fertility treatments and cell and gene therapies are set at 0%. Japan, the EU, South Korea and Switzerland/Liechtenstein pay 15%; the UK pays 10%. A company with a Commerce-approved onshoring plan pays 20%, and one with both an onshoring plan and a most-favored-nation pricing agreement with HHS pays 0% until January 20, 2029.
Do the 50% Canada tariffs apply to USMCA goods?
Yes, for the products on the list. The Section 338 duties took effect just after midnight ET on Saturday, August 22, 2026, after US-Canada trade talks collapsed the night before, and they apply whether or not the goods qualify under USMCA. Reported coverage is about US$20 billion of Canadian imports (AP, August 22, 2026), with Bloomberg citing a figure nearer US$28 billion — hockey sticks and hockey gear, cement, plywood, liquor and wine, dairy, electrical equipment, machinery, textiles and furniture. Energy, potash, fish, critical minerals and goods already covered by Section 232 are carved out. Prime Minister Mark Carney said Canada will match the duties "dollar for dollar"; the Canadian counter-list had not been published when these rates were verified.
How accurate are these estimates?
They are estimates of the additional duties layered on since 2025, above the normal (MFN) baseline rates that predate them. Exact duties depend on the product's HTS classification, rules of origin, and exemptions. Rates verified August 22, 2026.
