Section 201 HTS Codes: Safeguard Tariffs on Washers and Solar Cells

Full list of Section 201 safeguard Chapter 99 codes (9903.45.*), covering large residential washers and solar cells/modules, with product groupings and HTS tool guidance.

By Paige W.··Updated April 11, 2026

Quick Answer

The Section 201 safeguard family is 9903.45.*, covering two product groupings: large residential washers (9903.45.01-.06) and solar cells/modules (9903.45.21-.29). Section 201 is the main U.S. global safeguard authority under 19 U.S.C. 2251, based on USITC injury findings rather than national security or unfair trade practices. A code match alone is not sufficient; timing, product scope, and quota posture all affect whether the safeguard was collectible on a given entry date.

Informational only — not legal advice.

If your entry shows a 9903.45.* code, it belongs to the Section 201 safeguard family — but matching the code is only the first step. Unlike Section 232 or 301, where a code match usually means a duty was owed, Section 201 safeguards are time-limited and quota-governed. A code that was collectible in one quarter may not have been collectible in the next.

The two active product groupings are large residential washers (9903.45.01-.06) and solar cells / modules (9903.45.21-.29).

Background on Section 201

Section 201 is the main U.S. global safeguard authority under 19 U.S.C. 2251. It allows temporary import relief when the USITC finds that increased imports are a substantial cause of serious injury, or threat of serious injury, to a domestic industry.

That makes Section 201 different from 232 and 301. It is not about national security or unfair foreign practices. It is a product-specific remedy built around injury findings, presidential remedy decisions, and — critically — quota administration. Safeguard duties often step down over time, and tariff-rate quotas can change the effective rate within a single period.

Current status

As of April 11, 2026:

  • the live safeguard family is 9903.45.*
  • the two product groupings are large residential washers and solar cells / modules
  • schedule presence alone does not prove the safeguard was collectible on a specific entry date — you must check the entry date against the relevant proclamation chain and quota posture

Section 201 needs a date check

Common confusions

  • Section 201 lives in 9903.45.*, not 9903.03.*.
  • 9903.17.* and 9903.18.* are not shorthand for the washer / solar safeguard family.
  • A live 9903.45.* heading in the schedule does not automatically prove that the safeguard was collectible on the entry date you care about.
