3806.10.00 - Rosin and resin acids

HTS code 3806.10.00 covers natural rosin and resin acids, including their primary forms and direct derivatives. Rosin itself is a solid resin obtained from pine trees and other conifers, primarily composed of resin acids like abietic acid. This classification is fundamental for identifying these natural resinous materials before further processing or conversion into salts, esters, or other specific chemical products.

This category is distinguished from its siblings by its focus on the raw or minimally processed state of rosin and resin acids. HTS code 3806.20.00.00, for instance, specifically classifies salts derived from these materials, indicating a chemical transformation. Similarly, 3806.30.00.00 pertains to ester gums, which are produced through the esterification of resin acids, representing a further chemical modification. The "Other" category, 3806.90.00.00, is reserved for resinous products not specifically covered by the preceding headings.

Within HTS code 3806.10.00, two subcategories exist to refine the classification. 3806.10.00.10 identifies "Gum rosin," which is typically collected directly from living trees and has specific characteristics related to its collection method and composition. The remaining "Other" subcategory, 3806.10.00.50, encompasses all other forms of natural rosin and resin acids that do not fall under the definition of gum rosin, ensuring comprehensive coverage of this product group.
