HS Code for Chemical dissolving pulp

Chemical dissolving pulp is classified under HS code 4702.00. This classification is governed by the specific definitions provided in the Explanatory Notes to Chapter 47. Dissolving grade pulp is a high-purity chemical wood pulp, typically manufactured using the sulfite or sulfate (kraft) process, followed by extensive bleaching and purification. To qualify for this code, the pulp must have a very high alpha-cellulose content, usually exceeding 92% for sulfate pulp and 88% for sulfite pulp. This high purity is necessary because the pulp is intended for chemical conversion into various cellulose derivatives, such as viscose rayon, cellulose acetate, or cellophane, rather than for traditional papermaking. The classification under 4702.00 is distinct from other wood pulps because of its chemical reactivity and low levels of hemicellulose and lignin. According to the Harmonized System's structure, wood pulp intended for the manufacture of paper or paperboard is classified under headings 47.03 or 47.04. Therefore, the end-use and the chemical purity (alpha-cellulose content) are the primary factors in determining the correct classification under 4702.00.

Products Included

• High-alpha cellulose wood pulp
• Viscose grade pulp
• Acetate grade pulp
• Ether grade pulp
• Pulp for the manufacture of cellophane

Common Misclassification

The most common misclassification occurs with HS code 4703 (chemical wood pulp, soda or sulfate, other than dissolving grades) and HS code 4704 (chemical wood pulp, sulfite, other than dissolving grades). The distinction lies entirely in the alpha-cellulose content and the intended application. If the pulp is intended for papermaking and does not meet the high-purity thresholds for dissolving grades, it must be classified in 4703 or 4704. Additionally, cotton linters pulp is classified under 4706.10, even if it is of a dissolving grade, as heading 4702 is strictly reserved for wood-derived pulp.

FAQ

What is the HS code for chemical dissolving pulp?

The HS code for chemical wood pulp of dissolving grades is 4702.00.

How is dissolving pulp distinguished from paper-grade pulp?

Dissolving pulp is distinguished by its high alpha-cellulose content (typically >92%) and its intended use for chemical transformation into fibers or plastics, whereas paper-grade pulp has lower purity and is used for sheet formation.
