HS Code for Tetraethyl lead

Tetraethyl lead is classified under HS code 2931.10, which specifically identifies tetramethyl lead and tetraethyl lead within the broader category of organo-inorganic compounds. Organo-inorganic compounds are those in which the molecules contain one or more atoms of a non-metal or metal (such as lead, phosphorus, or arsenic) directly linked to carbon atoms. Tetraethyl lead (TEL) is a classic example of an organometallic compound, consisting of a central lead atom bonded to four ethyl groups. This specific subheading was created due to the historical significance and regulatory requirements surrounding lead-based fuel additives. While the use of TEL has been significantly phased out globally due to environmental and health concerns, it remains a distinct chemical entity for customs purposes. The classification under 2931.10 is reserved for the pure or technically pure compound; if it is mixed with other substances to create a finished anti-knock preparation, it is classified elsewhere. This distinction is crucial for environmental monitoring and the enforcement of international treaties regarding hazardous substances. The compound is highly toxic and requires specialized handling, which is why its specific classification is strictly maintained in the Harmonized System.

Common Misclassification

Tetraethyl lead is often misclassified under 3811.11, which covers anti-knock preparations based on lead compounds. The difference is that 3811.11 is for mixtures/preparations, while 2931.10 is for the pure chemical. It is also sometimes confused with inorganic lead compounds like lead sulfate, which fall under heading 2833.

FAQ

What is the HS code for tetraethyl lead?

The specific HS code for tetraethyl lead as a pure organo-inorganic compound is 2931.10.

Is tetraethyl lead still used in gasoline?
