HS Code for Coniferous bleached sulphite pulp

The classification of coniferous bleached sulphite pulp under HS code 4704.21 follows the structured hierarchy of the Harmonized System for wood pulp products. Heading 4704 is dedicated to chemical wood pulp produced by the sulphite process, which utilizes an acid bisulphite solution to separate cellulose fibers from the wood structure. This process is chemically distinct from the kraft process found in heading 4703. Subheading 4704.21 is reserved for pulp that has undergone a bleaching or semi-bleaching process and is sourced from coniferous wood species such as spruce, fir, or pine. The bleaching process removes residual lignin and other impurities to achieve a high degree of whiteness and chemical purity. This pulp is often used in specialty applications where high absorbance or specific chemical properties are required, such as in fine writing papers or tissue products. Classification requires verification of the chemical reagents used during pulping; if an alkaline process was used instead of an acid process, the product would be classified under a different heading entirely.

Products Included

• Bleached softwood sulphite pulp
• Semi-bleached spruce sulphite pulp
• Bleached fir sulphite pulp
• Bleached pine sulphite chemical pulp
• Bleached coniferous acid-process pulp

Common Misclassification

This product is often misclassified under HS code 4703.21, which is for bleached coniferous kraft pulp. While both are bleached and coniferous, the chemical process (sulphite vs. sulphate) is the primary differentiator. Another common error is using 4704.11, which is for unbleached coniferous sulphite pulp. If the pulp has been treated to increase brightness, it must be under 4704.21. Finally, 4704.29 is used for bleached sulphite pulp from non-coniferous (hardwood) sources and should not be used for softwood products.
