HS-4 · Heading

3804 — Residual lyes from the manufacture of wood pulp, whether or not concentrated, desugared or chemically treated, including lignin sulphonates, but excluding tall oil of heading no. 3803

Chapter 38: Miscellaneous chemical products

Plain-language overview

Use HS-4 3804 when importing residual lyes from wood pulp, such as those derived from the pulping process, whether they are concentrated, desugared, or chemically treated. For example, if you are shipping a container of lignin sulphonates, this code will apply.

When choosing between HS-6 lines, note that 380400 covers all residual lyes from wood pulp. If your product includes lignin sulphonates but is not tall oil (which falls under 3803), then this is the correct classification. Be careful not to confuse these with tall oil, as that would lead to incorrect duty assessments.

If your shipment involves a mixture of wood pulp by-products, ensure that it aligns with the definitions under 3804. This heading is specific to the residual lyes and excludes tall oil, which is a common point of confusion. Always verify the composition of your product to avoid misclassification.
