4701.00.00.00 - Mechanical woodpulp

This HTS category, 4701.00.00.00, specifically covers "Mechanical woodpulp." This encompasses pulp derived from wood that has been mechanically processed, typically through grinding or refining processes. The primary purpose of mechanical pulping is to separate wood fibers without significant chemical alteration, resulting in a pulp that retains most of the original wood components, including lignin. This type of pulp is commonly used in the production of paper and paperboard products where brightness and strength are not paramount, such as newsprint, packaging materials, and certain grades of printing paper.

Within the broader HTS framework, this classification is distinguished from other pulp categories by its manufacturing process. Unlike chemical pulps (covered in other headings), mechanical pulp relies on physical force rather than chemical treatment to break down wood into fibers. It also differs from pulps derived from other fibrous cellulosic materials, as the description explicitly specifies "wood." Furthermore, it is distinct from waste and scrap paper or paperboard (Chapter 47), which are recycled materials, and finished paper products (Chapter 48), which are manufactured goods.

As a leaf node, HTS 4701.00.00.00 does not have further subcategories. Classification within this heading is determined by the material being wood pulp produced through mechanical means. Therefore, specific classification considerations would focus on confirming that the pulp's origin is wood and that the production process involved mechanical separation of fibers, without significant chemical intervention that would classify it under a different heading.
