HS Code for Sebacic acid

Sebacic acid is a naturally occurring dicarboxylic acid with the formula (CH2)8(CO2H)2. Under the Harmonized System, organic chemicals are classified in Chapter 29. Specifically, acyclic polycarboxylic acids, their anhydrides, halides, peroxides, and peroxyacids are grouped under heading 29.17. Sebacic acid, along with azelaic acid, is explicitly named in subheading 2917.13. This classification is based on the chemical structure of the molecule, which consists of a straight carbon chain with two carboxylic acid groups. The code also encompasses the salts and esters of sebacic acid, such as dibutyl sebacate or dimethyl sebacate, which are frequently used as plasticizers or in the production of lubricants and cosmetics. The precise chemical identity of the substance as a saturated acyclic diacid ensures its placement in this specific category, regardless of whether it is derived from castor oil or synthetic sources. This classification is vital for chemical importers and exporters to ensure compliance with environmental and safety regulations, as sebacic acid is a key intermediate in the production of high-performance polymers like Nylon 6,10. The subheading 2917.13 is internationally harmonized, meaning it is recognized globally for this specific chemical compound and its immediate derivatives.

Common Misclassification

Sebacic acid is sometimes misclassified under 2915.90, which covers other saturated acyclic monocarboxylic acids. However, because sebacic acid has two carboxylic groups, it must be in 2917. It may also be confused with 2918.30 (carboxylic acids with aldehyde or ketone functions), but sebacic acid lacks these additional functional groups. Another error is using 3812.20 for plasticizers; while sebacic acid esters are plasticizers, the pure chemical remains in Chapter 29.
