4704.11.00.00 - Coniferous

This HTS category, 4704.11.00.00, specifically covers unbleached chemical wood pulp derived from coniferous wood that has been produced using the sulfite pulping process. This process involves breaking down wood chips using sulfite liquors, yielding a pulp primarily used in the manufacturing of paper and paperboard. The key defining characteristic is the source material (coniferous wood) and the specific pulping method employed, resulting in a pulp that has not undergone bleaching.

This classification is distinguished from its sibling category, 4704.19.00.00, which covers nonconiferous wood pulped via the sulfite process. Therefore, the determination between these two categories hinges on the botanical origin of the wood used for the pulp. Coniferous woods include softwoods such as pine, spruce, and fir, whereas nonconiferous woods encompass hardwoods like oak, maple, and birch.

As this is a leaf node within the HTS, there are no further subcategories under 4704.11.00.00. Classification at this level is complete based on the unbleached, sulfite-processed pulp originating from coniferous wood. Importers and exporters should ensure that the documentation accurately reflects the wood source and pulping method to facilitate correct classification and avoid potential customs delays.
