Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for semi-bleached or bleached sulfate pulp not meeting dissolving specs
If insoluble fraction below threshold, it becomes standard chemical pulp for paper, not dissolving applications.
If unbleached and for papermaking end-use
End-use for printing/writing paper shifts from dissolving to coniferous chemical woodpulp under 4703.

Import Tips & Compliance
• Include test reports confirming ≥92% insoluble in 18% NaOH; sulfate pulp must specify softwood vs hardwood origin
• Label shipments clearly as 'dissolving grades' with process details to prevent confusion with paper pulp under 4703
