Last updated: August 2026 dataSebacic acid — derived primarily from castor oil — and azelaic acid serve as specialty building blocks for high-performance lubricants, biodegradable plasticizers, and cosmetic-grade actives, giving this heading a notably diverse end-use profile. India and China together dominate US import supply, with India's position reflecting its established castor-oil processing industry. The US schedule distinguishes sebacic acid specifically at 2917130030 from azelaic acid and the broader salts and esters category at 2917130090. Imports from China may be subject to Section 301 tariffs, a material cost consideration for formulators sourcing sebacic acid for industrial lubricant applications.

Both are C9/C10 dicarboxylic acids but differ in carbon chain length and commercial origin: sebacic acid (C10) is predominantly castor-oil derived and classified at 2917130030, while azelaic acid (C9) and the remaining salts and esters fall under 2917130090. The distinction matters because end-use applications — lubricants vs. cosmetic actives vs. plasticizers — and trade-remedy exposure can differ by line.
India is the world's largest producer and exporter of castor oil, the primary feedstock for sebacic acid synthesis. This upstream raw-material advantage gives Indian manufacturers a structural cost edge, making India the top supplier under this heading to the US market.
