The US Department of Commerce (USDOC) decided that oil country tubular goods (OCTG) arriving from Thailand are subject to anti-dumping (AD) and countervailing duties (CVD) previously applied to Chinese goods.

The authority determined these items, produced by Thailand’s Boly Pipe Co., Ltd. (Boly Pipe) for Commercial Steel Products LLC (CSP) and JOL Tubular, Inc. (JOL Tubular), use steel billets from China.

This ruling stops the use of Thai manufacturing as a method to avoid existing trade regulations. The investigation into these shipments started on December 31, 2025. Therefore, these imports now face the same penalties as direct Chinese shipments to the US market. The USDOC determined the practice constitutes an evasion of established rules.
