Soda Chemical Woodpulp, Dissolving Grades
High-purity soda process chemical woodpulp with an insoluble fraction of 92% or more after caustic soda testing, designed for dissolving in chemical production. It falls under HTS 4702.00.00 as it meets the chapter definition for dissolving grades used in rayon and cellulose acetate manufacturing. This pulp is produced from softwood or hardwood via the soda process without sulfite.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If insoluble fraction <92% for soda pulp
Fails dissolving grade test per Chapter 47 note, classifying as sulfate pulp not for dissolving (e.g., paper-grade).
If mechanically processed rather than chemically
Mechanical woodpulp lacks chemical purity required for 4702, falling under semi-chemical or mechanical pulps.

Import Tips & Compliance
• Verify insoluble fraction ≥92% via lab test in 18% NaOH at 20°C to confirm dissolving grade classification
• Provide mill certificates showing chemical process (soda) and low ash content to avoid reclassification as non-dissolving pulp
