U.S. imports of unbleached coniferous chemical woodpulp, soda or sulfate (non-dissolving grade) (HS 470311) totaled $11.9M in July 2026, traded with 4 countries.
Unbleached Coniferous Chemical Woodpulp, Soda or Sulfate (Non-Dissolving Grade) imports of $11.9M in July 2026 ran 39% above the year-to-date monthly average of $8.5M.
Last updated: July 2026 dataKraft process dominates the production of unbleached coniferous pulp, yielding the high-tensile-strength brown fiber used in linerboard, kraft paper bags, and corrugated medium — packaging applications where strength matters more than brightness. Canada is the primary supplier to the US, with Chile, Sweden, and Finland also among the leading sources. The single 10-digit line (4703110000) covers all soda and sulfate unbleached coniferous grades, so softwood species mix (spruce, pine, fir) and kappa number are commercial rather than tariff variables.

Kappa number measures residual lignin content in unbleached pulp — a higher kappa indicates more lignin and greater potential for further bleaching or chemical treatment. It is a critical commercial specification affecting strength properties and downstream processing costs, but it has no bearing on HTS classification; all unbleached soda or sulfate coniferous pulp of non-dissolving grade falls under 4703110000 regardless of kappa number.
The decisive factor is alpha-cellulose content and intended end use: dissolving grades are processed to remove hemicelluloses and achieve high cellulose purity for textile or chemical conversion, while unbleached kraft pulp retains hemicelluloses and lignin for strength in paper and packaging applications. Mill certificates specifying grade designation (dissolving vs. paper/packaging grade) and cellulose content are the standard supporting documents for classification.
