Colophony Gum Rosin
Colophony gum rosin is the natural resin obtained from tapping the oleoresin of pine trees, primarily Pinus palustris species. It is classified under HTS 3806.10.0010 as gum rosin, distinct from wood rosin derived from processed wood stumps.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from wood stumps via extraction
Wood rosin from processed pine stumps falls under the residual 'other' subheading in 3806.10, not pure gum rosin.
If chemically modified (e.g., esterified or disproportionated)
Derivatives like rosin esters or fortified rosin are classified in 3806.20, separate from unmodified gum rosin acids.
If imported as crude oleoresin before distillation
Raw gum turpentine oleoresin (natural tree sap) is under 1301 as lac/gum exudations, prior to rosin separation.

Import Tips & Compliance
• Verify supplier certification that the rosin is from gum exudation (tree tapping), not wood extraction, to confirm HTS 3806.10.0010 classification
• Include chemical analysis or pine species origin documentation to distinguish from tall oil rosin
• Check for ISO 9001 certification on purity (levopimaric acid content) to avoid misclassification as lower-grade resins
