HS Code for Coniferous kraft pulp

Unbleached coniferous kraft pulp is classified under HS code 4703.11. This classification is determined by the chemical extraction method and the absence of subsequent bleaching treatments. Heading 4703 encompasses chemical wood pulp produced by the soda or sulphate (kraft) process. The term "kraft" refers to the strength of the resulting fibers, which are typically used for heavy-duty packaging materials. Subheading 4703.11 is specific to unbleached pulp derived from coniferous wood, such as pine or spruce. Because the pulp has not been bleached, it retains a natural brown color and a higher lignin content compared to bleached varieties. This makes it ideal for manufacturing kraft paper, linerboard, and corrugated medium where strength is more important than brightness. The classification process involves verifying that the wood source is softwood (coniferous) and that the pulping process was alkaline (sulphate or soda). Under the General Interpretative Rules, the unbleached state is a primary sub-classification factor for chemical wood pulp.

Products Included

• Unbleached softwood kraft pulp (UKP)
• Unbleached pine sulphate pulp
• Unbleached spruce kraft pulp
• Unbleached hemlock sulphate pulp
• Unbleached coniferous soda pulp

Common Misclassification

The most frequent misclassification is with HS code 4703.21, which is for bleached coniferous kraft pulp. Even a slight semi-bleaching treatment requires the product to be moved to the 4703.21 category. Another error is using 4703.19, which is for unbleached kraft pulp from non-coniferous (hardwood) sources. Additionally, if the pulp was produced using the acid sulphite process, it should be classified under 4704.11. Finally, mechanical wood pulp is classified under 4701.00 and should not be confused with chemical kraft pulp.
