U.S. exports of cyclanic, cyclenic, and cycloterpenic polycarboxylic acids and their derivatives (HS 291720) totaled $3.7M in August 2026.
Importers of Cyclanic, Cyclenic, and Cycloterpenic Polycarboxylic Acids and Their Derivatives paid $377K in duties in August 2026, an effective tariff rate of 14.09% of the $2.7M imported — duty actually collected as a share of that value, not the published tariff schedule.
Last updated: August 2026 dataPolycarboxylic acids with alicyclic ring structures — including cyclohexane dicarboxylic acids and their derivatives used as non-phthalate plasticizers and resin intermediates — are consolidated under a single 10-digit line (2917200000) in the US schedule. China and Japan are the leading suppliers, with Germany and India also significant sources, reflecting the global distribution of specialty chemical production for this class. Cyclohexane-1,2-dicarboxylic acid diisononyl ester (DINCH), a prominent phthalate alternative, is a commercially important product in this heading. Imports from China may be subject to Section 301 tariffs.

Yes, several derivatives in this heading — most notably DINCH (cyclohexane-1,2-dicarboxylic acid diisononyl ester) — are commercially positioned as phthalate-free plasticizers for sensitive applications such as medical devices and food-contact materials. However, regulatory status varies by jurisdiction and end-use; importers should verify compliance with FDA, REACH, or other applicable standards for their specific application.
Because all cyclanic, cyclenic, and cycloterpenic polycarboxylic acids and their derivatives share one 10-digit line (2917200000), classification itself is straightforward for pure products. The risk arises when a product could alternatively be classified as an aromatic compound or as a phthalate ester under a more specific heading — in those cases, the specificity rules of GRI 3 apply, and a licensed customs broker should review the chemical structure.
