The US has maintained antidumping and countervailing duty orders on certain polyethylene retail carrier bags and related plastic film products from multiple countries. Importers must check the current scope of active orders with the Department of Commerce and CBP before entry, as scope rulings can extend coverage to products that appear superficially different from the named merchandise.

Under the HTS, plastics film and sheet are generally distinguished by thickness: film is typically defined as material not exceeding a specified thickness threshold (often 0.25 mm), while sheet refers to thicker flat forms. The boundary matters because film and sheet may fall under different HTS subheadings with different duty rates, and the polymer type adds a further layer of classification specificity.
