Polyethylene Terephthalate (Pet) Film — South Korea — A-580-807

A measure titled “Polyethylene Terephthalate (PET) Film” is an antidumping and countervailing duty (AD/CVD) trade remedy. Antidumping duties address merchandise that is sold in the United States at less than fair value, while countervailing duties address benefits, or subsidies, provided by a foreign government. The measure generally concerns qualifying PET film, but coverage depends on the legal product description—not just the product name or tariff code.

It typically affects US importers, foreign producers and exporters, and sometimes related parties involved in importing covered merchandise. An importer may owe additional duties beyond ordinary customs duty and must use the correct tariff classification and any required AD/CVD case information. The importer of record is generally responsible for entry accuracy and payment, even when another party handles filing, so product specifications, origin, producer, exporter, and shipment documentation should be reviewed carefully. Borderline classification or scope questions may require a customs broker or trade counsel.

What to check

• Compare the product’s physical characteristics, composition, dimensions, coatings, and intended use with the measure’s official scope language; do not rely on the title alone.
• Confirm the correct Harmonized Tariff Schedule classification, while recognizing that an HTS number is an identification aid and does not by itself decide whether merchandise is covered.
• Identify the actual manufacturer, producer, exporter, country of origin, and any affiliated parties, and check whether the official measure lists company-specific instructions or requirements.
• Ask your customs broker to verify the applicable AD/CVD case information and entry instructions before filing, especially for new suppliers or unusual product configurations.
• Keep purchase orders, commercial invoices, product specifications, origin records, and supplier certifications that support the entry and any scope or duty determination.
