Vietnamese PTMEG Joins the Queue for a Delayed Trade Decision
Published Date: 11/10/2026
Notice
Summary
The U.S. Department of Commerce found that Vietnam is likely selling polytetramethylene ether glycol (PTMEG) in the U.S. for less than fair value, which could mean unfairly low prices. This affects Vietnamese exporters and could lead to extra duties to level the playing field. The final decision is delayed, and provisional measures are extended while the investigation continues through March 2026.
Analyzed Economic Effects
2 provisions identified: 0 benefits, 2 costs, 0 mixed.
36.55% Cash Deposit Required on PTMEG Imports
Beginning with entries entered or withdrawn from warehouse for consumption on or after November 10, 2026, U.S. Customs and Border Protection will require a cash deposit equal to the estimated weighted-average dumping margin of 36.55% for Hyosung Dong Nai Company Limited and for the Vietnam-wide entity on imports of polytetramethylene ether glycol (PTMEG). These suspension-of-liquidation instructions will remain in effect until further notice.
Provisional Measures Extended; Final Delayed
Commerce extended provisional measures for this antidumping investigation from a four-month period to a period not to exceed six months at the request of an exporter, and will postpone the final determination so it will be issued no later than 135 days after the publication date of the preliminary determination. This postponement and extension mean the provisional cash-deposit regime may remain in place longer while the investigation continues.
