U.S. Extends Duties on Stainless Pressure Pipe Imports from China
Estimated reading time: 1–3 minutes
On May 28, 2025, the U.S. Department of Commerce announced it will continue its antidumping and countervailing duty orders for circular welded austenitic stainless pressure pipe from China. This decision follows findings by both the Department of Commerce and the U.S. International Trade Commission (ITC).
The Department of Commerce and ITC agreed that removing these duties would likely cause more dumping—when products are sold at less than fair value—and let unfair government subsidies continue. They also found that ending the duties could hurt U.S. companies that make these pipes.
The duties first started in March 2009. Since then, the U.S. government has checked every five years to see if the duties are still needed. This latest check is the third five-year “sunset review” for these orders.
What Is Covered
The orders apply to circular welded austenitic stainless pressure pipe that is up to 14 inches wide. The pipe covered includes products made to meet ASTM A-312 or ASTM A-778 standards or similar standards from other countries. The orders do not cover mechanical tubing, certain boiler or heat exchanger tubes, and special tubing made to other ASTM standards.
Most of these pipes are listed in certain Harmonized Tariff Schedule of the United States (HTSUS) codes. The exact product description controls which items the orders cover.
Next Steps
U.S. Customs and Border Protection will keep collecting the antidumping and countervailing duty deposits on all covered pipe from China at current rates. The official continuation began on May 21, 2025, the same day the ITC shared its final decision.
The Department of Commerce will begin another five-year review of these orders on or before the fifth anniversary of this latest decision.
Rules for Businesses
The notice also reminds parties involved to return or destroy private information they received during this review process, according to federal rules.
This decision and the duties are being continued under U.S. law, following sections 751(c), 751(d)(2), and 777(i) of the Tariff Act of 1930 and related regulations.
The Deputy Assistant Secretary for Enforcement and Compliance, Abdelali Elouaradia, signed the order on May 21, 2025.
