Mechanical Pulps of Non-Wood Fibrous Cellulosic Materials (NESOI)

Common fibers include wheat straw, rice straw, sugarcane bagasse, hemp, flax, and similar agricultural residues processed mechanically rather than chemically. The distinction from bamboo pulp (4706300000) is straightforward — bamboo has its own dedicated subheading, so any mechanically processed non-wood pulp that is not bamboo, cotton linters, or recovered paper falls under 4706910000 as the NESOI (not elsewhere specified or included) category.

Heading 4706 is subdivided partly by processing method: 4706910000 covers mechanically produced non-wood pulps, while chemically produced non-wood pulps (other than cotton linters) fall under 4706920000. Importers must document the pulping process — whether fiber separation was achieved primarily through mechanical refining or through chemical digestion — to ensure correct classification between these two lines.
