Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

4703.21.00Lower: 25% vs 35%

If used for paper production rather than dissolving

Pulp not meeting dissolving grade solubility (under 92% insoluble) falls under chemical woodpulp for other uses like papermaking in 4703.

4701.00.00.00Same rate: 35%

If mechanically processed with chemical treatment

Semi-chemical or chemi-mechanical pulps are classified in 4701 based on production method, not purity for dissolving.

4702.00.00.20Same rate: 35%

If sulfite process instead of sulfate/soda

Sulfite dissolving pulps (88%+ solubility, ash ≤0.15%) go under the sulfite subheading within the same dissolving grades heading.

Import Tips & Compliance

Verify solubility test results (92%+ insoluble fraction in 18% NaOH) via lab certification to confirm dissolving grade status and avoid reclassification

Provide detailed chemical analysis reports including alpha cellulose, ash content (<0.15% for sulfite but applicable for quality), and brightness for CBP review
