Products classified under Tariff item 2909.11.00.00
Anhydrous Diethyl Ether
Anhydrous diethyl ether is a water-free form of diethyl ether, a chemically defined acyclic ether. It is commonly used as a solvent in Grignard reactions and other moisture-sensitive chemical syntheses. The anhydrous state is a standard purification method and does not render the product particularly suitable for a specific use, so it remains classified under tariff item 2909.11.00.
2909.11.00Diethyl Ether ACS Reagent Grade
Diethyl ether ACS reagent grade is a high-purity form of diethyl ether meeting American Chemical Society specifications for analytical procedures. It is a chemically defined acyclic ether and the ACS specifications ensure reagent purity without adding substances that would make it particularly suitable for a specific use. Therefore, it falls under tariff item 2909.11.00.
2909.11.00Diethyl Ether Extraction Solvent
Diethyl ether used as an extraction solvent for natural products such as essential oils and alkaloids is a chemically defined acyclic ether. Its use as a general solvent does not make it particularly suitable for a specific use, as it is a standard application of diethyl ether. Thus, it is classified under tariff item 2909.11.00.
2909.11.00Diethyl Ether (Laboratory Grade)
Laboratory grade diethyl ether is a pure, chemically defined acyclic ether used as a solvent in organic chemistry laboratories. It is a volatile, colorless liquid with a characteristic odor and contains no impurities or additives that would render it particularly suitable for a specific use. Therefore, it is classified under tariff item 2909.11.00.
2909.11.00Diethyl Ether Pharmaceutical Intermediate
Diethyl ether used as a pharmaceutical intermediate is a high-purity, chemically defined acyclic ether employed in the synthesis of pharmaceutical active ingredients. It is not excluded by Chapter 29 note 2(e) as it is not an immunological product. The product falls under tariff item 2909.11.00 as it is a chemically defined acyclic ether.
2909.11.00Stabilized Diethyl Ether
Stabilized diethyl ether contains a small amount of BHT (butylated hydroxytoluene) added to prevent peroxide formation during storage and transport. This stabilizer is necessary for preservation and is permitted under Chapter 29 note 1(f). The product remains classified as diethyl ether under tariff item 2909.11.00.
2909.11.00Technical Grade Diethyl Ether
Technical grade diethyl ether with a purity of 95-98% is used for industrial applications such as paint stripping and as a reaction solvent. It is a chemically defined organic compound containing impurities, which is permitted under Chapter 29 note 1(a). The product is classified under tariff item 2909.11.00 as diethyl ether.
