US Imposes Countervailing Duty on Korean Welded Pipe
The U.S. Department of Commerce has determined that producers and exporters of large diameter welded pipe from South Korea received countervailable subsidies during 2023. This final result of a countervailing duty administrative review will impose duties on Korean welded-pipe imports to offset government subsidies deemed to distort fair trade. Shippers and importers sourcing this product from Korea must factor in additional landed costs and comply with duty-assessment requirements.

On May 14, 2026, the U.S. Department of Commerce issued final results of a countervailing duty administrative review, concluding that producers and exporters of large diameter welded pipe from the Republic of Korea received countervailable subsidies during the 2023 review period (January 1–December 31, 2023).
Who Is Affected
This determination applies to manufacturers and exporters of large diameter welded pipe in South Korea. Any U.S. importer purchasing welded pipe from Korean suppliers during or after this review period must expect countervailing duties to be assessed on entry into the United States.
Large diameter welded pipe typically falls under HS Chapter 73 (Iron and Steel Products). The specific tariff classification may vary depending on pipe diameter, wall thickness, grade, and end use, but the countervailing duty applies across the product category as defined in the investigation scope.
Countervailing Duty Assessment
Countervailing duties are designed to offset subsidies granted by a foreign government that distort international trade. The Commerce Department's finding means that Korean producers benefited from government support that artificially reduced their costs, allowing them to compete unfairly against U.S. domestic producers. The final results will establish the duty rates applicable to entries of subject merchandise.
Importers and freight forwarders must monitor the Federal Register and Commerce Department announcements for:
- Specific duty rates assigned to each Korean producer/exporter
- Effective dates for duty collection
- Any continuation of the duty order or further administrative reviews
What this means for shippers
If you import large diameter welded pipe from Korea, recalculate your landed costs immediately to include countervailing duties—your margins are at risk if you've been pricing without this protection. Verify your supplier's producer status and any applicable duty rates on the Commerce Department's trade enforcement database. Review your supply-chain strategy now: absorb the duty, pass it to customers, or diversify sourcing away from Korea. This ruling may remain in effect for years unless the duty order is revoked. /landed-cost
