HS Code for Styrene film

Styrene film is classified under HS code 3920.30. This code falls under heading 3920, which includes plates, sheets, film, foil, and strip of plastics that are non-cellular and not reinforced, laminated, supported, or similarly combined with other materials. The classification process involves identifying the polymer type and the physical structure of the plastic. Since the film is made from polymers of styrene and lacks a cellular (foam-like) internal structure, it is directed to subheading 3920.30. This classification excludes products that have been treated with adhesives or those that have been reinforced with fiberglass or metal. The material must be flat and have a consistent thickness to meet the definition of film or sheet under this heading. It is commonly used in packaging, printing, and industrial applications where a clear or rigid styrene-based surface is required.

Products Included

• Non-adhesive polystyrene film
• Rigid styrene sheets
• Biaxially oriented polystyrene (BOPS) film
• Transparent styrene foil
• Non-cellular styrene plastic strips

Common Misclassification

Styrene film is frequently misclassified under HS code 3919.10 or 3919.90 if it has a self-adhesive backing. Heading 3919 specifically takes precedence for adhesive-coated plastics. Another common error is using HS code 3921.11, which is reserved for cellular (foam) plates and sheets made of styrene. If the film is reinforced with a textile or metal layer, it would also move to heading 3921. Additionally, if the film is worked beyond simple surface treatment (e.g., cut into specific shapes other than rectangles), it may be classified as an article of plastic under 3926.

FAQ

What is the HS code for Styrene film?

The HS code for non-cellular, non-reinforced styrene film is 3920.30.

Is polystyrene foam classified under this code?

No, polystyrene foam is a cellular plastic and is classified under HS code 3921.11, not 3920.30.
