4805.11.00.00 - Semichemical fluting paper

This classification, HTS Code 4805.11.00.00, specifically covers "Semichemical fluting paper." This type of paperboard is a crucial component in the manufacture of corrugated fiberboard, providing the cushioning and structural integrity required for shipping containers and packaging. It is characterized by a manufacturing process that utilizes a combination of mechanical and chemical pulping methods, resulting in a paper with specific strength and flexibility properties essential for its intended use as the fluted layer in corrugated board.

Distinguishing this category from its siblings, 4805.12 (Straw fluting paper) and 4805.19 (Other fluting paper), hinges on the primary cellulosic fiber source and pulping method. Semichemical fluting paper is differentiated by its production from wood pulp (or other fibrous cellulosic materials) processed via a semichemical pulping technique, which imparts distinct physical characteristics compared to papers made solely from straw or other less refined processes. The "semichemical" designation is the key differentiator.

As this is a leaf node within the HTS classification, there are no further subcategories. Therefore, the focus for importers and exporters is on correctly identifying and documenting that the fluting paper in question is produced through a semichemical pulping process, distinguishing it from other fluting paper types based on raw material and manufacturing technique. Correct classification ensures accurate duty assessment and compliance with trade regulations.
