4704.19.00.00 - Nonconiferous

This HTS category, 4704.19.00.00, specifically classifies unbleached chemical wood pulp produced by the sulfite process, but *excluding* dissolving grades. This type of pulp is derived from wood fibers and is intended for further processing into paper, paperboard, and other cellulosic products, but not for the production of regenerated cellulose materials like rayon or cellophane.

The key differentiator for this subcategory is its designation as "Nonconiferous." This means the wood pulp is made from hardwoods such as oak, maple, or birch, as opposed to the "Coniferous" subcategory (4704.11.00.00), which covers pulp derived from softwoods like pine or spruce. The choice of wood species significantly impacts the characteristics and intended end-uses of the pulp.

As this is a leaf node in the HTS classification, there are no further subcategories. Classification within 4704.19.00.00 is determined by the unbleached state, the sulfite pulping method, and the origin of the wood pulp from nonconiferous (hardwood) species. The absence of bleaching indicates that residual lignin and other wood components are still present, which may influence its suitability for certain paper grades requiring higher brightness or purity.
