4703.29.00 - Nonconiferous

This HTS classification covers nonconiferous chemical wood pulp that has been produced using the soda or sulfate pulping process, and is not intended for dissolving grades. This means the pulp is derived from hardwood trees and other non-coniferous plant materials, and has undergone chemical treatment to separate the cellulose fibers. The pulp is suitable for various paper and paperboard manufacturing applications, but not for specialized uses like rayon or cellophane production.

This category specifically excludes coniferous wood pulp, which is classified under 4703.21.00. The distinction lies in the botanical origin of the wood used. While both are chemically pulped via the soda or sulfate method, this sub-heading focuses exclusively on pulp originating from deciduous trees or other non-coniferous sources.

Within this nonconiferous category, further distinctions are made based on the degree of bleaching. Subcategories exist for "Semibleached" (4703.29.00.20) and "Bleached" (4703.29.00.40) pulps. Semibleached pulp has undergone partial bleaching to achieve a moderate brightness, while bleached pulp has been treated to achieve a higher degree of whiteness, impacting its suitability for different paper grades and applications requiring specific optical properties.
