Acrylonitrile for Adiponitrile Production
Acrylonitrile refined specifically for hydrocyanation to adiponitrile, a precursor in nylon-6,6 production. This pure nitrile-function compound meets the definition of a separate chemically defined organic compound under Chapter 29, regardless of its intended end-use in the synthetic fiber chain.
Acrylonitrile Monomer
Pure acrylonitrile monomer (CH2=CHCN), a colorless liquid unsaturated nitrile-function compound used primarily as a chemical intermediate. It is a separate chemically defined organic compound, qualifying under Chapter 29 for tariff item 2926.10.00.
Acrylonitrile Technical Grade
Commercial technical grade acrylonitrile with 98-99% purity, containing minimal water and aldehydes. This separate chemically defined compound is used for bulk plastics manufacturing such as SAN copolymers, and falls under tariff item 2926.10.00.
Acrylonitrile with Anti-Dusting Agent
Liquid acrylonitrile with a trace odoriferous substance added for spill identification, as permitted by Chapter 29 note 1(g). The addition facilitates safety without making the product suitable for a specific use, so it remains under tariff item 2926.10.00.
Bulk Acrylonitrile ISO Tank
Bulk acrylonitrile shipped in 20MT ISO tanks with nitrogen padding, a standard transport form for this chemically defined compound. It is classified under tariff item 2926.10.00 for large-scale resin production, as the nitrogen padding is a safety measure.
Distilled Acrylonitrile 99.5%
Vacuum-distilled acrylonitrile with 99.5% purity and controlled aldehyde content below 20 ppm. This pure nitrile-function compound is used for high-performance ABS and modacrylic fiber manufacture, falling under tariff item 2926.10.00.
