Sub-classifications

Commodity Code
Description

Overview

This HTS category, 3921, encompasses a broad range of plastic materials presented in the form of plates, sheets, film, foil, and strip. These are essentially flat forms of plastics that are not otherwise specified under more specific headings within Chapter 39. The key distinguishing factor for inclusion here is that the material must be a plastic and take one of these flat configurations. This heading serves as a residual category for such plastic products when they do not fit into more narrowly defined categories based on their specific plastic composition, cellular structure, or intended use.

Unlike sibling categories at the root of the HTS, which focus on live animals, heading 3921 is specifically concerned with manufactured goods derived from plastics. Within Chapter 39 itself, heading 3921 is distinct from earlier headings that might cover plastic powders, granules, or primary forms, as well as those for specific manufactured articles like pipes or containers. The distinction from other headings for plastic sheeting often lies in the absence of a cellular structure (covered by subheadings like 3921.10) or a specific reinforcing material.

The subcategories within 3921 further refine the classification based on specific characteristics. For instance, the "Cellular" subheading is for plastic plates, sheets, film, foil, and strip that have a cellular structure, such as expanded or foamed plastics. The "Other" subheading is a residual for all other non-cellular plastic plates, sheets, film, foil, and strip that do not meet the criteria for specific subheadings. This hierarchical structure allows for precise tariff classification based on whether the plastic material is solid or cellular and its general form.
