Polytetramethylene Ether Glycol — Vietnam — A-552-855

An AD/CVD measure combines two trade-remedy programs: antidumping (AD), which addresses imports sold at less than fair value, and countervailing duties (CVD), which address certain government subsidies benefiting foreign producers or exporters. For a measure based on Polytetramethylene Ether Glycol (PTMEG), the key issue is whether the merchandise matches the official product scope—not simply whether the invoice uses the name “PTMEG.”

The measure typically affects U.S. importers, foreign producers and exporters, and sometimes related parties in the supply chain. If covered merchandise enters the United States, the importer of record may need to provide an additional cash deposit and could later face a final duty assessment. Classification under the Harmonized Tariff Schedule (HTSUS) helps identify entries, but the written scope, product characteristics, country of origin, and applicable producer or exporter information control whether the measure applies. Confirm difficult scope or origin questions with a customs broker or trade-remedy specialist.

What to check

• Read the official scope language and compare it with the product’s chemistry, composition, physical form, specifications, and intended use; do not rely on the product name alone.
• Confirm the country of origin and identify the actual producer and exporter, including any related-party transactions or changes in manufacturing.
• Review the applicable HTSUS provisions as an entry-screening tool, while remembering that an HTSUS number does not by itself decide scope coverage.
• Ask your customs broker to verify the required entry reporting, cash-deposit treatment, and any producer- or exporter-specific instructions before importation.
• Check for scope rulings, exclusions, certifications, or other official instructions that may apply to the exact product and transaction.
