Products classified under HTS 2917.13.00
Azelaic Acid Powder
Pure azelaic acid in crystalline powder form, a dicarboxylic acid with 9 carbon atoms used primarily in cosmetics for acne treatment and rosacea. Classified under HTS 2917.13.00 as it is specifically azelaic acid, falling within acyclic polycarboxylic acids. Meets chapter 29 note (a) as a separate chemically defined organic compound.
Sebacic Acid Flakes
Sebacic acid in flake form, a 10-carbon dicarboxylic acid derived from castor oil, used in nylon 610 production and lubricants. Directly covered by HTS 2917.13.00 as sebacic acid without salts or esters. Qualifies under chapter 29 for separate chemically defined organic compounds.
Dimethyl Azelate (DMA)
Dimethyl ester of azelaic acid, a colorless liquid used as solvent and intermediate in polymer synthesis. HTS 2917.13.00 classification follows chapter ester rule (A), subordinate to azelaic acid subheading. Meets purity standards for chemically defined compound.
Sebacic Acid Calcium Salt
Calcium sebacate, used as lubricant in PVC processing and corrosion inhibitor in coatings. HTS 2917.13.00 per explicit inclusion of sebacic acid salts and chapter note (C)(3) for metal salts. Fine white powder form.
Polysebacic Acid Polymer
Low molecular weight polysebacic acid (oligomer <1000 Da), used in drug delivery systems. Technically the polymer but classified as sebacic acid derivative under HTS 2917.13.00 when not meeting polymer definitions. Meets chapter 29 compound criteria.
Sebacic Acid Zinc Salt
Zinc sebacate, used as heat stabilizer in PVC and antifungal agent in coatings. HTS 2917.13.00 per metal salt classification rule following sebacic acid. Fine powder with 14-16% zinc content.
Dioctyl Sebacate (DOS)
Di(2-ethylhexyl) sebacate, an ester of sebacic acid with 2-ethylhexanol, used as plasticizer in PVC for low-temperature flexibility. Classified under HTS 2917.13.00 per chapter note on esters following the parent acid subheading. Clear oily liquid meeting acyclic polycarboxylic acid ester definition.
Azelaic Acid Monosodium Salt
Sodium azelate, the monosodium salt of azelaic acid, used in biodegradable polymers and corrosion inhibitors. Covered by HTS 2917.13.00 explicitly including salts of azelaic acid. White powder per chapter note (C)(1) classified with parent organic compound.
Dibutyl Sebacate (DBS)
Dibutyl sebacate plasticizer for nitrocellulose lacquers and vinyl resins, offering good low-temp performance. Ester of sebacic acid classified HTS 2917.13.00 following parent acid per chapter notes. Low volatility clear liquid.
Azelaic Acid Diethyl Ester
Diethyl azelate, a diester used in synthesis of low molecular weight polyesters and as cross-linking agent. HTS 2917.13.00 classification per ester rule subordinate to azelaic acid. Colorless liquid with fruity odor.
