Duty Rate (from China)
Products classified under Tariff item 2922.17.00
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.
Methyldiethanolamine (MDEA)
Methyldiethanolamine (MDEA) is a tertiary amino alcohol with the chemical formula CH3N(CH2CH2OH)2, classified under tariff item 2922.17.00 as a specific oxygen-function amino-alcohol. It is a colorless viscous liquid used in gas treatment and as a chemical intermediate.
Methyldiethanolamine with Anticaking Agent
Methyldiethanolamine with an added anticaking agent necessary for preservation, as permitted under Chapter Note 1(f). The additive is minimal and does not affect its use in agricultural chemical formulations, so it remains under tariff item 2922.17.00.
Purified Methyldiethanolamine 99% Technical Grade
Purified methyldiethanolamine (99% min) is a chemically defined tertiary amino alcohol, meeting Chapter Note 1(a) for separate organic compounds. It is used in natural gas purification to remove hydrogen sulfide, falling under tariff item 2922.17.00.
