International Emergency Economic Powers Act (50 U.S.C. §§ 1701–1708)
TERMINATED. IEEPA tariffs are not being collected and have not been replaced, per TLR (Clark Buffam, 2026-10-01). Do NOT add IEEPA duties to a current duty estimate. Entries made while IEEPA tariffs were in force may still have refund / liquidation questions: check CBP CSMS.

Per TLR (Clark Buffam, 2026-10-01): IEEPA tariffs are dead and not replaced. The 2025 IEEPA tariff Executive Orders were challenged in court; refund mechanics for past entries depend on CBP liquidation status. Monitor CBP CSMS bulletins for refund guidance.

Section 232 tariffs are additional import duties imposed by the President under the Trade Expansion Act of 1962 when the Department of Commerce determines that certain imports threaten national security. Since 2018, the US has applied 25% tariffs on steel products (HTS chapters 72 and 73) and aluminum products (HTS chapter 76). As of March 2025, the aluminum rate was increased from 10% to 25%, and all country exemptions -- including for USMCA partners Canada and Mexico -- were removed.
Section 301 tariffs are additional duties on Chinese-origin goods imposed under the Trade Act of 1974 in response to findings that China's trade practices are unreasonable or discriminatory. These tariffs cover approximately $370 billion of imports across four tranches (Lists 1 through 4A) at rates ranging from 7.5% to 25%. In 2024-2025, rates on specific product categories were increased further: electric vehicles to 100%, semiconductors and solar cells to 50%, lithium-ion batteries to 25%, and ship-to-shore cranes to 25%.
IEEPA tariffs are additional duties imposed under the International Emergency Economic Powers Act (50 U.S.C. §§ 1701–1708) — typically via Executive Order following a declared national emergency. Unlike Section 232/301, which follow a statutory investigation, IEEPA tariffs can be imposed, amended, or revoked rapidly. Several 2025 IEEPA-based tariff orders have been challenged in the Court of International Trade and the Federal Circuit; importers tracking potential refunds should monitor CBP CSMS bulletins for liquidation guidance, Federal Register notices for EO amendments, and pending court decisions.
Antidumping & countervailing duties (AD/CVD) are case-specific additional duties administered under Title VII of the Tariff Act of 1930. Commerce (ITA) calculates dumping margins and subsidy rates per exporter/producer; USITC determines material injury. Deposit rates vary by case and are adjusted through administrative and sunset reviews.
All four categories are applied on top of the normal Most Favored Nation (MFN) duty rate, and multiple categories can apply to the same entry. For binding classification and duty determinations, consult a licensed customs broker or trade attorney.
