HS Code for Unbleached kraft pulp
Unbleached kraft pulp is classified under HS code 4703.11, which specifically covers chemical wood pulp produced using the soda or sulfate process. This classification is restricted to pulp derived from coniferous wood, such as pine, spruce, or fir. The 'unbleached' status indicates that the pulp has not undergone chemical whitening processes, retaining its natural brown color and high lignin content, which contributes to its superior strength. The sulfate process, commonly known as the 'kraft' process (from the German word for strength), involves cooking wood chips in a mixture of sodium hydroxide and sodium sulfide. This process is highly effective at dissolving lignin while preserving the cellulose fibers. HS code 4703.11 excludes 'dissolving grades' of pulp, which are high-purity pulps used for chemical applications rather than papermaking. This pulp is a primary raw material for the production of high-strength paper products like linerboard and sack kraft paper.

Common Misclassification
A frequent misclassification occurs with HS code 4703.19, which is for unbleached chemical wood pulp from non-coniferous (hardwood) sources like eucalyptus or birch. Another common error is 4703.21, which covers coniferous kraft pulp that has been bleached or semi-bleached. Additionally, importers must distinguish this from HS code 4701.00 (mechanical wood pulp) or 4702.00 (chemical wood pulp, dissolving grades). The distinction between coniferous and non-coniferous is a botanical one and is strictly enforced by customs laboratories through fiber analysis.
