North American Industry Classification System
U.S. imports of All Other Basic Organic Chemicals (NAICS 325199) totaled $2.8B in August 2026, imported from 125 countries.
Importers of All Other Basic Organic Chemicals paid $263.7M in duties in August 2026, an average duty rate of 10.15% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. All Other Basic Organic Chemicals imports of $2.8B in August 2026 ran 19% above the year-to-date monthly average of $2.3B.
Last updated: August 2026 dataResidual basic organic chemical manufacturing — covering compounds such as organic acids, esters, ethers, aldehydes, ketones, and specialty intermediates not elsewhere classified — is captured at NAICS 325199. These chemicals are critical inputs for agrochemical formulation, flavor and fragrance production, polymer synthesis, and electronic chemicals. The category's diversity means trade flows span a wide range of HTS chapters, and importers frequently encounter classification ambiguity between pure chemical compounds and prepared mixtures. Supply-chain concentration in certain specialty organic intermediates — particularly those sourced from China and India — has prompted risk-management reviews among pharmaceutical and agrochemical manufacturers seeking to qualify alternative suppliers.

Customs brokers typically require a certificate of analysis (CoA) confirming chemical identity and purity, a Safety Data Sheet (SDS), and often a manufacturer's product specification sheet. For chemically defined compounds, the CoA purity level is critical to supporting Chapter 29 classification versus a mixture classification in Chapter 38. Some compounds may also require a TSCA certification.
For intermediates where one or two countries dominate global production capacity, importers should evaluate whether alternative qualified suppliers exist in other regions, the lead time required to qualify a new source against internal specifications, and whether any trade-remedy measures (antidumping, Section 301) create cost asymmetries that could shift sourcing economics rapidly.
