Tetraethyl Lead (TEL) from China

Tetraethyl lead is an aromatic organo-inorganic compound used historically as an antiknock additive in gasoline. It falls under HTS 2931.90.30.00 as a product described in additional U.S. note 3 to section VI, specifically aromatic organo-inorganic compounds with metal-carbon bonds. Classified here due to its organometallic structure containing lead directly linked to carbon.

Import Tips

Verify inclusion in additional U.S. note 3 to section VI and obtain chemical analysis certificates confirming aromatic organo-inorganic classification

Comply with EPA regulations on lead compounds; provide safety data sheets and transport permits for hazardous materials

Avoid misclassification as petroleum additives (Chapter 27); emphasize organometallic structure in documentation
