Subheadings
Products classified under Tariff item 2924.19.00
Acetamide
Acetamide is a simple acyclic amide derived from acetic acid, with the chemical formula CH3CONH2. It is used as a solvent, plasticizer, and in organic synthesis. As a separate chemically defined organic compound, it falls under tariff item 2924.19.00 for other acyclic amides.
Acetamide Sodium Salt
Sodium acetamide is the sodium salt of acetamide, used in organic reactions and buffers. Per Chapter 29 note 5(C)(1), inorganic salts of organic compounds are classified with the organic compound, so it falls under tariff item 2924.19.00.
Acrylamide Flake Form Stabilized
Acrylamide in flake form with a polymerization inhibitor (e.g., copper sulfate <0.1%) is a chemically defined acyclic amide. The stabilizer is permitted under Chapter 29 note 1(f) as necessary for transport, so it falls under tariff item 2924.19.00.
Acrylamide Monomer
Acrylamide monomer (CH2=CHCONH2) is a chemically defined acyclic amide used primarily as a monomer in polymerization reactions. It falls under tariff item 2924.19.00 as an other acyclic amide.
Acrylamide with MEHQ Inhibitor
Acrylamide with 30-50 ppm MEHQ (4-methoxyphenol) as a polymerization inhibitor is a chemically defined acyclic amide. The stabilizer is allowed under Chapter 29 note 1(f), so it falls under tariff item 2924.19.00.
Butyramide
Butyramide (C3H7CONH2) is a linear acyclic amide used as an intermediate in pesticide and flavor synthesis. It is a separate chemically defined organic compound, qualifying under tariff item 2924.19.00 for other acyclic amides.
Dimethylacetamide (DMAC)
N,N-Dimethylacetamide (DMAC) is a polar aprotic solvent and amide derivative with the formula CH3CON(CH3)2. It is used in pharmaceuticals and fiber production. As a chemically defined acyclic amide, it falls under tariff item 2924.19.00.
Ethyl Carbamate (Urethane)
Ethyl carbamate, also known as urethane, is an acyclic carbamate ester-amide used historically in medicine and now in research. It is a chemically defined compound, falling under tariff item 2924.19.00 for other acyclic amides and carbamates.
Formamide
