Status: Section 232 tariffs on steel, aluminum and copper were adjusted again in 2026 (most recently in June). Section 301 China tariffs remain in force. Last reviewed June 2026.
The short version
While the IEEPA tariffs were struck down in 2026, the two other major tariff regimes importers deal with — Section 232 and Section 301 — are very much still active. Section 232 on steel, aluminum and copper was modified more than once during 2026, with expanded coverage on some derivatives, revised thresholds, and adjusted rates. Section 301 tariffs on Chinese goods continue under their own framework. If you import metals or China-origin goods, these are the tariffs that still hit your landed cost.
Section 232: steel, aluminum, and copper
Section 232 tariffs are national-security measures on specific metals and a growing list of derivative products. During 2026 the regime was adjusted by presidential proclamation more than once — adjusting rates, revising the thresholds that determine how derivatives are treated, and changing which products are covered. The practical takeaway for importers and brokers: the Section 232 scope is a moving target, so the classification that was correct last quarter may not be correct this quarter. Re-check coverage on metal-containing entries regularly.
Section 301: China-origin goods
Section 301 tariffs apply to goods of Chinese origin across defined product lists. They are separate from both IEEPA and Section 232 and were not affected by the Supreme Court ruling. Section 301 has historically operated with its own exclusion process — a way to request relief for specific products — which is distinct from the IEEPA refund process and follows its own timelines.
How these interact with IEEPA refunds
An entry can carry IEEPA, Section 232, and Section 301 duties at the same time. The 2026 ruling only removes the IEEPA portion. So when you estimate a refund, isolate the IEEPA duty lines and leave the 232 and 301 amounts out of the calculation. For the full breakdown, see which of your tariffs are refundable.
Frequently asked questions
Did the IEEPA ruling change Section 232 or 301?
No. The ruling was specific to IEEPA’s tariff authority. Section 232 and Section 301 rest on different statutes and continue to apply.
How do I keep up with Section 232 changes?
Watch for presidential proclamations and CBP guidance, and re-verify the classification and coverage of metal-containing products periodically. Because the derivative lists and thresholds shifted during 2026, brokers are re-checking affected entries rather than assuming prior treatment still holds.
Can I get relief from Section 301 tariffs?
Section 301 operates with its own product-exclusion mechanism, separate from IEEPA refunds. Whether an exclusion is available depends on the product and the current state of the exclusion process.
