IEEPA HTS Codes: Complete Chapter 99 Reference for Importers

Full list of IEEPA Chapter 99 code families (9903.01.*, 9903.02.*), historical status after the Supreme Court ruling, and how to look up IEEPA codes in the HTS tool.

By Paige W.··Updated March 16, 2026

Quick Answer

The IEEPA Chapter 99 code families are 9903.01.* and 9903.02.*, plus companion headings 9903.96.01-.02. These codes appeared on U.S. import entries during the 2025-2026 IEEPA tariff program. After the Supreme Court ruled IEEPA does not authorize tariffs, CBP ended collection on February 24, 2026. Codes may still appear in the published schedule for historical reference, but date is part of the analysis.

This page is the evergreen code reference for the IEEPA Chapter 99 families that appeared on U.S. import entries during the 2025–2026 IEEPA tariff program.

If you see one of these 9903 numbers on a Form 7501, ACE export, or broker spreadsheet, click the exact code below first. The goal is to get the reader into the HTS tool from the authority page, then back out to the underlying Chapter 1-97 classification and any other overlays on the line.

Background on IEEPA

IEEPA is the International Emergency Economic Powers Act, a statute that gives the president broad powers to regulate economic transactions during a declared national emergency involving an unusual and extraordinary foreign threat.

In 2025, the Trump administration used IEEPA as the claimed authority for multiple import-duty programs, including fentanyl-supply-chain tariffs and reciprocal tariffs. That made IEEPA different from Section 232, 301, or 201: it was being used as an emergency-powers statute rather than a traditional trade-remedy statute. That legal theory was heavily contested and ultimately failed in the Supreme Court, which is why IEEPA code references now have both a historical and a refund/litigation dimension.

Current status

As of March 16, 2026:

  • the Supreme Court has held that IEEPA does not authorize tariffs on imports
  • CBP ended IEEPA duty collection effective February 24, 2026 at 12:00 a.m. ET
  • some IEEPA headings still remain visible in later USITC HTS revisions for historical/reference reasons

That means a code can still appear in the published schedule or on an older entry without being collectible on a later entry date. For IEEPA, date is part of the analysis.

How to use this page with our HTS tool

  1. Click the exact 9903 code shown on the entry.
  2. In the HTS tool, confirm the code family and read the note/reference context.
  3. Then compare it with the underlying Chapter 1-97 HTS number on the same line.
  4. If the entry has more than one Chapter 99 number, review all of them before deciding the authority.

Start with the Chapter 99 code you actually see

If a 7501 or ACE export shows 9903.01.33, 9903.02.41, or another IEEPA code, click that exact code first. Do not start from a news summary or a country headline.

Common confusions

  • IEEPA is not the same thing as Section 122. The replacement Section 122 family is 9903.03.*, not 9903.01.* or 9903.02.*.
  • IEEPA is not the same thing as Section 232, Section 301, or Section 201, even though all of them use Chapter 99.
  • Current schedule presence does not prove current collectibility. For IEEPA, you must use the entry date and the February 24, 2026 CBP cutover.
