Sulfite Chemical Woodpulp, Dissolving Grades from China
Sulfite process chemical woodpulp with ≥88% insoluble fraction and ash ≤0.15%, used in high-purity applications like cellulose derivatives. HTS 4702.00.00 covers this due to strict chapter note criteria for dissolving grades. Commonly sourced from beech or spruce for acetate film production.

Import Tips
• Mandatory ash content certification ≤0.15% for sulfite pulp; test both solubility and ash to meet dual criteria
• Declare production process explicitly on commercial invoice to distinguish from soda/sulfate variants
