Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If nitrogen function predominates over oxygen
Chapter notes prioritize oxygen functions in 2918, but added nitrogen may shift to 2922 per note 4.
If benzoic acid derivative without glycolic alcohol function
Simplified benzoic esters without additional alcohol group classify under 2916.
If used as pesticide intermediate in formulation
Pesticide goods containing such compounds shift to Chapter 38 if for specific pesticidal use.

Methyl Benzilate
Methyl benzilate is the methyl ester of benzilic acid, a chemically defined aromatic carboxylic acid with alcohol function but without other oxygen function. It falls under HTS 2918.19.1100 as a specific enumerated product in the subcategory for aromatic derivatives. This compound is typically used as an intermediate in pharmaceutical synthesis.
Methyl Diphenylglycolate
Methyl diphenylglycolate, synonymous with methyl benzilate, is a white crystalline powder that is the methyl ester derivative of benzilic acid. Classified under HTS 2918.19.1100 due to its aromatic structure and specific identification in the tariff schedule for benzilic acid methyl ester. Primarily serves as a synthetic intermediate in organic chemistry.
Benzilic Acid Methyl Ester USP Grade
USP-grade benzilic acid methyl ester is a high-purity form of this aromatic compound used in pharmaceutical research and API synthesis. It qualifies for HTS 2918.19.1100 as the specifically named methyl ester of benzilic acid, meeting Chapter 29's criteria for separate chemically defined organic compounds. The USP designation ensures compliance with pharmacopeia standards.
Methyl Benzilate Technical Grade
Technical-grade methyl benzilate contains minor impurities but remains a separate chemically defined compound per Chapter 29 note (a), classifying under HTS 2918.19.1100. Used in industrial organic synthesis for dyes and polymers. The specific naming in the tariff overrides general purity concerns.
