Vulcanized Fiber Gaskets and Washers

Thin noncellular sheets and strips of vulcanized fiber cut into gasket and washer forms for mechanical seals. Vulcanized fiber's oil and water resistance makes it ideal for automotive and machinery applications. These are plates/sheets of a cellulose derivative, not reinforced or combined.

Cellophane Candy Wrapper Sheets

Pre-printed 0.03 mm cellophane sheets for individual hard candy wrappers. Cellophane is regenerated cellulose, a cellulose derivative, and the printing is subsidiary to the primary packaging use. These are thin noncellular films, not reinforced or combined with other materials.

Cellophane Conservation Archival Film

Acid-free 0.04 mm cellophane for document conservation interleaving sheets. Cellophane is regenerated cellulose, a cellulose derivative, and the film is noncellular and unsupported. These sheets are used to protect documents without chemical interaction.

Cellophane Packaging Film

Thin, transparent cellophane film made from regenerated cellulose, typically 0.02-0.05 mm thick, used for wrapping food products like candies and cigarettes. It falls under this tariff item as a noncellular film of a cellulose derivative, not reinforced or combined with other materials.

Cellophane Tape Backing Film

Clear 0.035 mm regenerated cellulose film serving as backing for transparent adhesive tapes. This is a noncellular, unreinforced sheet of a cellulose derivative, not exceeding 0.076 mm in thickness. The film is not combined with adhesive, which would change classification.

Cellulose Acetate Capacitor Dielectric Film

High-purity 0.01 mm cellulose acetate film for use as dielectric layers in electronic capacitors. Cellulose acetate is a cellulose derivative, and the film is noncellular, unreinforced, and not exceeding 0.076 mm in thickness. The purity meets the 95% polymer content rule for classification.

Vulcanized Fiber Abrasive Backing Sheets

Non-reinforced vulcanized fiber sheets used as backing for bonded abrasives and sanding discs. Vulcanized fiber is a cellulose derivative processed with zinc chloride, giving it exceptional tear strength for high-speed applications. These sheets are in primary plate/sheet form and are not reinforced or combined with other materials.
