U.S. imports of cyclohexanone and methylcyclohexanones (HS 291422) totaled $20K in June 2026, traded with 5 countries.
Cyclohexanone and Methylcyclohexanones imports of $20K in June 2026 ran 17% above the year-to-date monthly average of $17K.
Cyclohexanone — a primary precursor in nylon-6 and nylon-6,6 production — and its methyl-substituted analogs are split into two dedicated US tariff lines: cyclohexanone (2914221000) and methylcyclohexanones (2914222000). Japan and Taiwan are the leading US import sources for this heading, reflecting the concentration of downstream polyamide and solvent manufacturing in East Asia. Cyclohexanone is also a significant industrial solvent for resins, lacquers, and cellulose esters, making accurate line-level classification important where duty rates differ between the two lines. Importers should confirm the specific compound — cyclohexanone versus a methyl-substituted variant — before filing.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The two lines — 2914221000 for cyclohexanone and 2914222000 for methylcyclohexanones — may carry different duty rates and are tracked separately for trade-remedy and statistical purposes. Cyclohexanone's role as a nylon intermediate gives it distinct commercial significance, justifying its own enumerated line.
A certificate of analysis specifying the CAS number and purity is the most reliable document. Cyclohexanone is CAS 108-94-1; the methylcyclohexanone isomers carry different CAS numbers. CBP may request this documentation to verify the correct 10-digit line.
