4703.29.00.20 - Semibleached

This HTS classification covers semibleached chemical wood pulp, specifically soda or sulfate pulp, derived from nonconiferous (hardwood) sources. Semibleaching indicates a degree of whitening, but the pulp has not undergone the full bleaching process to achieve the highest levels of brightness typically associated with fully bleached grades. This material serves as a primary input for various paper and paperboard products, as well as other cellulosic applications where a specific degree of brightness and fiber characteristics are required.

This category is distinguished from its sibling, HTS 4703.29.00.40, which is designated for fully "Bleached" nonconiferous soda or sulfate pulp. The critical difference lies in the extent of the chemical treatment applied to remove lignin and other impurities. Semibleached pulp, while having undergone some whitening, retains a slightly lower brightness and may have residual color compared to its fully bleached counterpart, influencing its suitability for different end-use applications where absolute whiteness is not the primary requirement.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification at this level is determined by the material (chemical wood pulp), the pulping process (soda or sulfate), the degree of bleaching (semibleached), and the wood source (nonconiferous). Careful examination of the product's technical specifications, including its ISO brightness and residual lignin content, will be essential for accurate classification within this specific code.
