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.
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.
This page is the evergreen code reference for the Section 201 safeguard family.
Section 201 is different from most other authority pages because it is one of the easiest places to make a bad inference from the live schedule alone. The code family is real, but active collection and quota posture can still depend on the product, time period, and proclamation chain.
Background on Section 201
Section 201 is the main U.S. global safeguard authority. 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 safeguard remedy built around injury findings, presidential remedy decisions, and often quota administration. That is also why Section 201 code matching is only the start of the analysis: timing, product scope, and quota posture matter a lot.

9903.45.*heading in the schedule does not automatically prove that the safeguard was collectible on the entry date you care about.
