U.S. imports of adipic acid, its salts and esters (HS 291712) totaled $2.1M in June 2026, traded with 18 countries.
Importers of Adipic Acid, Its Salts and Esters paid $206K in duties in June 2026 — an effective duty rate of 17% on $1.2M in dutiable value, based on actual customs collections rather than the published tariff schedule. Adipic Acid, Its Salts and Esters imports of $2.1M in June 2026 ran 12% below the year-to-date monthly average of $2.4M.
Adipic acid is the dominant precursor for nylon-6,6 production and a key intermediate in polyurethane and plasticizer chemistry, making it a high-volume industrial chemical in the US import schedule. The US tariff schedule divides the heading into three 10-digit lines: pure adipic acid (2917121000), salt and ester plasticizers (2917122000), and other salts and esters excluding plasticizers (2917125000). Canada leads supply, followed by the Netherlands and South Korea, reflecting both proximity and the concentration of global nylon-chain production in those regions. Importers should note that certain adipic acid derivatives may be subject to Section 301 measures depending on origin.

The schedule separates pure adipic acid (2917121000) from salt and ester plasticizers (2917122000) and all other salts and esters not used as plasticizers (2917125000). Correct classification depends on the specific derivative form and its intended end use, so importers should confirm the chemical specification and application with a licensed customs broker.
Imports of certain acyclic polycarboxylic acid derivatives originating from China may be subject to Section 301 tariffs. While Canada and the Netherlands are the leading suppliers under this heading, importers sourcing from China should verify current Section 301 applicability for the specific 10-digit line with a licensed customs broker before entry.
