US antidumping duty upheld on Vietnamese stainless steel pressure pipe
The U.S. Department of Commerce has issued final results of its administrative review for welded stainless steel pressure pipe (WSSP) from Vietnam, confirming that Vietnamese exporters continued to sell the product at less than normal value during July 1, 2023–June 30, 2024. This means antidumping duties remain in place on covered imports. Importers and freight forwarders sourcing WSSP from Vietnam must account for these duty rates in landed-cost calculations and customs declarations.

On May 20, 2026, the U.S. Department of Commerce issued final results of its antidumping duty administrative review, confirming ongoing below-market pricing by Vietnamese producers of welded stainless steel pressure pipe (WSSP). The determination covers the period July 1, 2023 through June 30, 2024.
Who is affected
Importers, distributors, and freight forwarders bringing WSSP into the United States from Vietnam must apply antidumping duties to their shipments. Welded stainless steel pressure pipe falls under HS Chapter 73 (Iron and Steel). The "Vietnam-wide entity" designation means the findings apply broadly to Vietnamese producers and exporters unless they secured separate rate determinations in earlier reviews.
"Commerce continues to determine that the Vietnam-wide entity made sales of welded stainless steel pressure pipe from the Socialist Republic of Vietnam at less than normal value (NV) during the period of review (POR) July 1, 2023, through June 30, 2024."
This is an administrative review—a routine annual or periodic reassessment of antidumping margins. Because Commerce found continued dumping, the existing antidumping duty order remains enforceable, and shipments are subject to cash deposits or bonds equal to the current rate.
What normal value means
In antidumping law, "normal value" (NV) is the price at which the product is sold in the exporter's home market or to other third countries. When export prices fall below NV, that gap constitutes dumping. Commerce's finding that Vietnamese WSSP sales remained below normal value justifies continued duties to level the playing field for U.S. domestic producers.
Customs implications
Shippers and customs brokers must:
- Confirm the current antidumping duty rate (stated in the Commerce determination but referenced via the order number in effect).
- File entries with the correct duty liability code.
- Post cash deposits or obtain a bond for the full antidumping amount at time of entry.
- Retain documentation of origin and producer/exporter for potential review in future administrative cycles.
What this means for shippers
Any shipment of welded stainless steel pressure pipe from Vietnam now entering U.S. commerce must clear antidumping duties. Review the specific rate assigned to your Vietnamese exporter and update your landed-cost model accordingly; failure to account for the full duty can blow through margins on delivered price. Confirm your customs broker has the latest duty rate and order number before you clear any container.
