4703.21.00.20 - Semibleached

This HTS category, 4703.21.00.20, specifically classifies semibleached chemical wood pulp derived from coniferous trees, produced by either the soda or sulfate pulping process, and not intended for dissolving grades. Semibleaching involves a partial bleaching process, resulting in a pulp that is whiter than unbleached pulp but less so than fully bleached pulp. This intermediate level of whiteness is often suitable for a variety of paper products where high brightness is not the primary requirement.

It is crucial to distinguish this category from its sibling, 4703.21.00.40, which covers *bleached* coniferous chemical wood pulp. The key difference lies in the extent of the bleaching process. Semibleached pulp retains some of the natural color of the wood fibers, whereas bleached pulp undergoes a more intensive treatment to achieve a significantly higher degree of whiteness and brightness. This distinction in processing directly impacts the visual characteristics and end-use applications of the pulp.

As this is a leaf node in the HTS database, there are no further subcategories under this specific code. Therefore, classification at this level relies on accurately identifying the pulp as semibleached, derived from coniferous wood, and produced via the soda or sulfate method, while excluding dissolving grades. Examples of end products that might utilize this type of pulp include certain types of packaging paper, paperboard, and some printing papers where a natural, less bright appearance is acceptable.
