HS Code for Cellulose derivative sheets

Cellulose derivative sheets are classified under HS code 3920.79 based on their chemical composition and physical form. According to the General Rules of Interpretation (GRI) 1 and 6, products are classified according to the terms of the headings and subheadings. Heading 3920 covers plates, sheets, film, foil, and strip of plastics that are non-cellular and not reinforced, laminated, or similarly combined with other materials. Within this heading, the subheadings are organized by the specific type of plastic. While 3920.71 covers regenerated cellulose and 3920.73 covers cellulose acetate, the 3920.79 subheading serves as the residual category for other cellulose derivatives. These materials are polymers modified by chemical treatment of cellulose, such as nitration or etherification, resulting in distinct industrial plastics used in various manufacturing sectors. The classification requires that the sheets are not self-adhesive and have not been combined with textiles or other reinforcing layers, which would otherwise move the product to heading 3921. The technical nature of these sheets, being non-cellular and non-reinforced, is the primary driver for their placement in this specific tariff line.

Products Included

• Vulcanized fiber sheets used for electrical insulation
• Cellulose nitrate (celluloid) sheets for decorative items
• Ethylcellulose films for specialized industrial packaging
• Cellulose propionate strips for manufacturing applications
• Non-reinforced methylcellulose sheets

Common Misclassification

These products are frequently confused with HS code 3920.71, which is strictly for regenerated cellulose (cellophane). Another common error is 3920.73, which is reserved for cellulose acetate. If the sheets are reinforced with glass fibers or laminated with other materials, they must be classified under 3921.90. Additionally, if the sheets have a self-adhesive layer, they fall under heading 3919. It is critical to distinguish between the chemical derivative and the physical structure (cellular vs. non-cellular) to avoid incorrect duty payments.

FAQ

What is the HS code for cellulose derivative sheets?

The primary HS code for non-cellular, non-reinforced sheets made of cellulose derivatives (other than acetate or regenerated cellulose) is 3920.79.

How does reinforcement affect the classification of cellulose sheets?

If the cellulose derivative sheet is reinforced, laminated, or supported by other materials, it is excluded from 3920 and classified under heading 3921, which specifically covers other plates and sheets of plastics.
