Stabilized Acrylonitrile
Acrylonitrile with added stabilizers like hydroquinone to prevent polymerization during storage and transport. Classified under HTS 2926.10.00.00 per Chapter 29 note (f) as the stabilizer is necessary for preservation without changing its primary chemical identity. Used in industrial synthesis of nitrile rubber and ABS resins.

Acrylonitrile Monomer
Pure acrylonitrile (CH2=CHCN) is a colorless liquid unsaturated nitrile-function compound used primarily as a chemical intermediate. It falls under HTS 2926.10.00.00 as it is a separate chemically defined organic compound with a nitrile function. This classification applies to the monomer in its standard commercial form for polymerization and synthesis.
High Purity Acrylonitrile 99.9%
Ultra-pure grade acrylonitrile meeting polymerization specifications with <10 ppm impurities. This chemically defined nitrile-function compound is classified in HTS 2926.10.00.00 for use in specialty acrylic fiber production and pharmaceutical intermediates.
Acrylonitrile Technical Grade
Commercial technical grade acrylonitrile (98-99% purity) containing minimal water and aldehydes. Falls squarely under HTS 2926.10.00.00 as a separate chemically defined compound for bulk plastics manufacturing like SAN copolymers.
MEHQ Inhibited Acrylonitrile
Acrylonitrile inhibited with 4-methoxyphenol (MEHQ) at 30-50 ppm for extended shelf life. Chapter 29 note (f) permits this stabilizer addition, maintaining HTS 2926.10.00.00 classification for transport to polymer plants.
Acrylonitrile for Adiponitrile Production
Specialty acrylonitrile refined for hydrocyanation to adiponitrile (nylon-6,6 precursor). As a pure nitrile-function compound, classified under HTS 2926.10.00.00 despite specific end-use in synthetic fiber chain.
Polymerization-Grade Acrylonitrile
Low-residue acrylonitrile (<50ppb hydrocyanic acid) for direct emulsion/solution polymerization. Meets Chapter 29 definition of separate chemically defined compound, thus HTS 2926.10.00.00 for acrylic fiber and paint production.
