4823.90.60.00 - Gaskets, washers and other seals

This classification, HTS Code 4823.90.60.00, pertains to gaskets, washers, and other seals made from paper, paperboard, or cellulose wadding. These items are specifically designed for sealing purposes and are manufactured by cutting these cellulosic materials to size and shape. The emphasis is on their function as barriers to prevent leakage of fluids or gases, or to prevent ingress of contaminants.

Within the broader category of "Other paper, paperboard, cellulose wadding and webs of cellulose fibers, cut to size or shape; other articles of paper pulp, paper, paperboard, cellulose wadding or webs of cellulose fibers," this subheading distinguishes itself by focusing on items that serve a specific sealing function. It is important to note that while these are made from paper-based materials, their primary classification is based on their form and intended use as seals, rather than their general paper or paperboard characteristics.

As a leaf node, HTS Code 4823.90.60.00 does not have further subdivisions. Therefore, classification within this code requires a careful assessment of the product's physical form and its definitive role as a gasket, washer, or other type of seal. Examples could include paper-based crush washers for plumbing, specialized paper gaskets for machinery, or sealing rings cut from cellulose wadding. The material itself, while originating from paper or paperboard, is secondary to its engineered purpose.
