Distilled Ethyldiethanolamine Industrial Grade
Distilled ethyldiethanolamine, a separate chemically defined organic compound, is purified by distillation to industrial grade. It is used primarily as a catalyst in polyurethane foam production, falling under tariff item 2922.17.00 as an amino-alcohol.
Ethyldiethanolamine Color-Coded for Safety
Ethyldiethanolamine with a minimal colouring agent added for safety identification, as permitted by Chapter Note 1(g). The colouring does not alter its use as a general chemical intermediate, so it remains classified under tariff item 2922.17.00.
Ethyldiethanolamine (EDEA)
Ethyldiethanolamine (EDEA), a tertiary amino alcohol with the formula C2H5N(CH2CH2OH)2, is explicitly listed under tariff item 2922.17.00. This clear liquid serves as a chemical intermediate in various industrial applications, including the production of surfactants and corrosion inhibitors.
Ethyldiethanolamine with Stabilizer for Transport
Ethyldiethanolamine with a minimal stabilizer added for preservation during transport, as allowed under Chapter Note 1(f). The stabilizer does not change its classification as the base amino-alcohol compound under tariff item 2922.17.00, and it is used in emulsifier manufacturing.
High-Purity Methyldiethanolamine for Gas Sweetening
Ultra-high purity methyldiethanolamine (>99.5%) is a separate chemically defined organic compound, specifically used for natural gas sweetening to remove acid gases. It falls under tariff item 2922.17.00 as a pure oxygen-function amino-alcohol.
Methyldiethanolamine Aqueous Solution 50% for Safety Transport
A 50% aqueous solution of methyldiethanolamine, prepared solely for safe transport, qualifies under Chapter Note 1(d) and (e). The water solvent does not make the product suitable for a specific use, so it falls under tariff item 2922.17.00, used for pH adjustment in industrial processes.
