Subheadings
Products classified under HTS 3806.10.00
WW Grade Wood Rosin
WW grade wood rosin is extracted from pine stumps via solvent extraction, yielding high-purity resin acids standardized by color and acid number. It is widely used in printing inks and adhesives. HTS 3806.10.00 covers it as 'rosin and resin acids' regardless of wood extraction method.
Pimaric Acid Crystals
Pimaric acid crystals are a levopimaric resin acid from pine rosin, used in specialty adhesives and as a chiral reagent. Isolated via crystallization. HTS 3806.10.00 includes specific resin acids like pimaric as part of rosin acids.
Color Grade K Rosin
Color grade K rosin is dark-colored gum rosin with high resin acid content, used in tire tackifiers and low-end adhesives. Graded by Gardner scale. Under HTS 3806.10.00 as standard rosin acids.
Gum Rosin
Gum rosin is a natural resin acid derived from the oleoresin of pine trees, primarily consisting of abietic acid and other resin acids. It is obtained by distillation of crude turpentine and processed into solid form. Classified under HTS 3806.10.00 as it directly falls within 'rosin and resin acids' from natural pine sources.
Abietic Acid Powder
Abietic acid powder is the primary resin acid component of rosin, isolated and purified for use in pharmaceuticals and fine chemicals. It constitutes 30-50% of natural rosin. Falls under HTS 3806.10.00 as a specific 'resin acid' from rosin sources.
Tall Oil Rosin
Tall oil rosin is produced from by-products of wood pulping, containing resin acids like pimaric and abietic acids. It is distilled for use in soaps and paper sizing. Classified in HTS 3806.10.00 as 'rosin and resin acids,' distinct from crude tall oil.
Refined Pine Rosin Acids
Refined pine rosin acids are purified extracts from slash pine, with minimized impurities for electronics flux. Acid number typically 165+. HTS 3806.10.00 for refined forms of natural rosin acids.
