3912.11.00.00 - Nonplasticized

This HTS classification, 3912.11.00.00, pertains to cellulose acetates that are specifically nonplasticized. Cellulose acetate is a derivative of cellulose, a natural polymer found in plants, which has undergone chemical modification through acetylation. The key characteristic defining this category is the absence of added plasticizers, which are substances incorporated to increase flexibility and reduce brittleness. Therefore, the products classified here are rigid or semi-rigid forms of cellulose acetate, such as films, sheets, or molding compounds, that have not been treated with these additives.

The primary distinction of this category from its sibling, 3912.12.00.00 (Plasticized cellulose acetates), lies in the presence or absence of plasticizers. While both are cellulose acetates, the latter category encompasses those that have been specifically modified with plasticizers to enhance their pliability and workability for applications requiring a softer or more flexible material. This classification hinges on whether plasticizers have been intentionally added during the manufacturing process.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Classification at this level is determined by the fundamental chemical derivative (cellulose acetate) and its physical state regarding plasticization. Customs officers and traders will rely on product specifications, ingredient lists, and potentially laboratory analysis to confirm the absence of plasticizing agents when classifying goods under 3912.11.00.00. Examples of goods that might fall here include rigid photographic films (before the widespread adoption of polyester) or certain types of clear plastic sheets used in packaging or industrial applications where flexibility is not a primary requirement.
