HS code for Coniferous bleached kraft pulp: 4703.21
Wood pulp, chemical wood pulp, soda or sulphate, (other than dissolving grades), semi-bleached or bleached, of coniferous wood.
Classification of coniferous bleached kraft pulp under HS 4703.21
Coniferous bleached kraft pulp is classified under HS code 4703.21. This classification is based on three primary criteria: the chemical process used, the botanical origin of the wood, and the treatment of the pulp after extraction. Heading 4703 covers chemical wood pulp produced via the soda or sulphate (kraft) process. The kraft process involves the use of sodium hydroxide and sodium sulphide to dissolve the lignin that binds the cellulose fibers, resulting in a high-strength pulp. Subheading 4703.21 specifically identifies pulp that is semi-bleached or fully bleached and derived from coniferous (softwood) trees like pine, spruce, or fir. Bleaching is a chemical process used to increase the brightness and purity of the pulp, making it suitable for high-quality paper production. According to the Explanatory Notes to Chapter 47, this code excludes dissolving grades of pulp, which have a higher alpha-cellulose content and are classified under 4702.00. The distinction between coniferous and non-coniferous wood is critical, as the fiber length and strength properties differ significantly between the two botanical groups.

Codes often confused with 4703.21
Common mistake. The most common misclassification occurs with HS code 4703.11, which is for unbleached coniferous kraft pulp. If the pulp has undergone any bleaching process, it must move to 4703.21. Another error is using 4703.29, which is for bleached kraft pulp derived from non-coniferous (hardwood) species like eucalyptus or birch. Importers also confuse this with 4704.21, which covers bleached coniferous pulp produced by the sulphite process rather than the kraft (sulphate) process. The chemical reagents used in production are the deciding factor between these codes.
Top exporters and importers of HS 470321 (the code used for coniferous bleached kraft pulp), 2025
In 2025, the largest exporter of HS 470321 (the code used for coniferous bleached kraft pulp) in UN Comtrade data was the United States, with 27% of world exports; the largest importer in UN Comtrade data was China, with 37% of world imports.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

How do I classify Coniferous bleached kraft pulp for customs?
Coniferous bleached kraft pulp is classified under HS code 470321 — Wood pulp; chemical wood pulp, soda or sulphate, (other than dissolving grades), semi-bleached or bleached, of coniferous wood. This is a 6-digit subheading level code.
What is the difference between kraft and sulphite pulp in the HS system?
Kraft pulp (Heading 4703) is produced using an alkaline process (soda or sulphate), while sulphite pulp (Heading 4704) is produced using an acid process. This chemical distinction is fundamental to their classification.
