Tariff Impact Checker

Your HTS codes and country of origin against active and announced US trade actions. That currently includes the Section 301 forced-labor tariffs that took effect Jul 24, 2026, and the Section 338 tariffs on Canadian goods scheduled for Aug 19, 2026. You'll see current versus previous duty rates, upcoming effective dates, and any published exclusions that might waive the duty.

Section 301 (Trade Act of 1974) is how the US tariffs goods from countries it says are engaging in unfair trade practices. It's not new, duties on Chinese goods under this authority go back to 2018 and are still active. What changed is scope: after the IEEPA tariffs were struck down earlier in 2026, the administration leaned harder on Section 301, expanding it to roughly 60 trading partners with forced-labor-related tariffs, 10% for countries with a US trade agreement, 12.5% for those without, current as of July 2026. Some of these rates calculate on top of the standard MFN duty rather than adding separately, so how measures interact matters as much as the headline percentage.

Section 232 (Trade Expansion Act of 1962) covers tariffs justified on national security grounds. In practice, that's meant steel, aluminum, copper, automobiles, and the derivative parts that go into them.

Section 338 (Tariff Act of 1930) is an old, rarely invoked authority that lets the president impose duties up to 50% on a country found to discriminate against US trade. It sat unused for decades until Jul 20, 2026, when three proclamations applied a 50% tariff to a wide range of Canadian goods, set to take effect Aug 19, 2026. USMCA/CUSMA-qualifying goods aren't automatically exempt here, whether a code is covered depends on the HTS classification itself, not the certificate of origin. If your country of origin is Canada, we'll flag any codes that appear on the published lists.

Section 122 (Trade Act of 1974) allowed a temporary, economy-wide import surcharge of up to 15%, capped at 150 days unless Congress extended it. It filled the gap after the Supreme Court struck down the IEEPA tariffs, running Feb 24 to Jul 24, 2026, when Section 301 measures took over. It's here for context, it's not a live charge anymore.

Almost every tariff action carves out some exceptions, goods already in transit, donated goods, certain product categories, or in the Canada case, energy, potash, and anything already under Section 232. Where a measure has published exclusions, we list them alongside the HTS headings and sources they came from. Confirming whether one applies to your specific shipment is still worth doing, with your broker, or with our HTS Tariff Lookup tool for the classification piece.

Our trade team updates this as soon as new measures are published. If there's been a major announcement, check back, or just run the tool again.

No. Treat it as a starting point, not a final answer. For anything tied to an actual shipment, talk to one of our trade experts.

It means none of your codes matched anything on our current list. We still show them so you can see they were checked, not just skipped.
