Products classified under Tariff item 2917.13.00.00
Azelaic Acid Diethyl Ester
Diethyl azelate is a diester of azelaic acid, a colorless liquid with a fruity odor. It is used in the synthesis of low molecular weight polyesters and as a cross-linking agent. Under Chapter 29 Note 5(A), esters of acid-function organic compounds are classified with the parent acid, so this falls under tariff item 2917.13.00.
2917.13.00Azelaic Acid Monosodium Salt
Sodium azelate is the monosodium salt of azelaic acid, a white powder used in biodegradable polymers and corrosion inhibitors. Chapter 29 Note 5(C)(1) classifies inorganic salts of organic compounds with the parent organic compound, placing it under tariff item 2917.13.00.
2917.13.00Azelaic Acid Powder
Azelaic acid in crystalline powder form is a pure dicarboxylic acid with nine carbon atoms, used in cosmetics for acne treatment and rosacea. It is explicitly named in tariff item 2917.13.00, and Chapter 29 Note 1(a) covers separate chemically defined organic compounds.
2917.13.00Bio-Based Sebacic Acid Granules
Bio-based sebacic acid granules are renewable sebacic acid derived from castor oil, granulated for metering in biodegradable polymer production. The bio-origin does not affect classification, and it falls under tariff item 2917.13.00 as sebacic acid.
2917.13.00Dibutyl Sebacate (DBS)
Dibutyl sebacate is an ester of sebacic acid used as a plasticizer for nitrocellulose lacquers and vinyl resins, offering good low-temperature performance. Per Chapter 29 Note 5(A), esters are classified with the parent acid, so this falls under tariff item 2917.13.00.
2917.13.00Dimethyl Azelate (DMA)
Dimethyl azelate is the dimethyl ester of azelaic acid, a colorless liquid used as a solvent and intermediate in polymer synthesis. Chapter 29 Note 5(A) classifies esters with the parent acid, placing it under tariff item 2917.13.00.
2917.13.00Dioctyl Sebacate (DOS)
Dioctyl sebacate, also known as di(2-ethylhexyl) sebacate, is an ester of sebacic acid used as a plasticizer in PVC for low-temperature flexibility. Under Chapter 29 Note 5(A), it is classified with the parent acid, sebacic acid, in tariff item 2917.13.00.
2917.13.00Distilled Sebacic Acid from Castor Oil
Distilled sebacic acid from castor oil is obtained via oxidation and distillation of ricinoleic acid, used in lubricants. It is a separate chemically defined compound, classified under tariff item 2917.13.00 as sebacic acid.
2917.13.00High Purity Sebacic Acid Powder
High purity sebacic acid powder is micronized sebacic acid with purity greater than 99.8%, used in precision applications like hot-melt adhesives. It is explicitly named in tariff item 2917.13.00, and Chapter 29 Note 1(a) covers separate chemically defined organic compounds.
