HS Code for Refined tall oil

Refined tall oil is classified under HS code 3803.00. This code is unique because it covers tall oil regardless of whether it is in its crude or refined state. Tall oil, also known as liquid rosin, is a byproduct of the Kraft process used in wood pulp manufacture. During the pulping of coniferous trees, fatty acids and rosin acids are saponified into soluble soaps. These soaps are skimmed off and acidified to produce crude tall oil. Refined tall oil is obtained through the fractional distillation of crude tall oil to separate various components or to improve its purity and color. The classification under 3803.00 is straightforward because the heading specifically names the product. However, the degree of refinement is important for trade statistics and regulatory compliance. If the tall oil is further processed into specific isolated fatty acids with a purity of 90% or more, it may be classified elsewhere, but standard refined tall oil mixtures remain here. The chemical complexity of tall oil, containing a mix of resin acids (like abietic acid) and fatty acids (like oleic and linoleic acid), justifies its placement in Chapter 38 for miscellaneous chemical products rather than Chapter 15 for vegetable oils. The classification is governed by GRI 1, which states that classification is determined by the terms of the headings. Since 3803 specifically mentions tall oil, whether or not refined, it takes precedence over more general chemical or oil headings. Refined tall oil is used extensively in the production of adhesives, rubbers, and lubricants, and its classification ensures it is treated as an industrial chemical rather than a food-grade oil.

Products Included

Common Misclassification

Refined tall oil is often confused with tall oil fatty acids (TOFA) classified under 3823.13, which requires a fatty acid content of 90% or more. It may also be misclassified under 3806.10 (rosin) if the resin acid content is the primary focus. Furthermore, it should not be confused with fixed vegetable oils under heading 1515, as tall oil is a chemical byproduct of wood pulp rather than a direct agricultural oil extraction.

FAQ

What is the HS code for refined tall oil?

The HS code for refined tall oil is 3803.00, which covers tall oil whether or not refined.

Is distilled tall oil classified differently?

No, distilled tall oil remains under HS code 3803.00, as the heading explicitly includes refined versions of the oil.
