HS Code for Parathion

Parathion is classified under HS code 2920.11. This classification is determined by its chemical structure as an ester of an inorganic acid. Specifically, parathion is a thiophosphoric ester (phosphorothioate). Heading 2920 covers esters of other inorganic acids of non-metals and their salts. Subheading 2920.11 is specifically designated for Parathion (ISO) and Parathion-methyl (ISO). The classification follows the principle that pure, chemically defined organic compounds are classified in Chapter 29. Even though parathion is a potent insecticide, it is classified here when it is in its technical grade or pure form, rather than as a formulated pesticide product ready for retail sale. The presence of the sulfur atom replacing oxygen in the phosphate group characterizes it as a phosphorothioate, which is a key factor in its specific sub-classification within the 2920 group. This substance is subject to various international trade regulations, such as the Rotterdam Convention, but its HS classification remains strictly tied to its chemical composition under Chapter 29. The classification process involves identifying the functional groups; since it is an ester of thiophosphoric acid, it must fall under 2920. The specific mention of Parathion in the subheading 2920.11 provides a clear, non-ambiguous path for customs declaration, provided the material is not mixed with carriers or surfactants that would transform it into a prepared pesticide.

Products Included

• Technical grade Parathion
• Parathion-methyl (ISO)
• Ethyl parathion (pure)
• Thiophosphoric esters of parathion

Common Misclassification

The most common misclassification is HS code 3808.91, which covers insecticides put up in forms or packings for retail sale. If the parathion is mixed with other ingredients to be used directly as a pesticide, it moves from Chapter 29 to Chapter 38. Another confusion arises with 2920.19, which is for other thiophosphoric esters not specifically named.

FAQ

What is the HS code for Parathion?

The HS code for Parathion is 2920.11.

When should Parathion be classified under Chapter 38?

It should be classified under Chapter 38 (specifically 3808.91) when it is formulated as a finished insecticide product, such as a spray or powder ready for use, rather than a pure chemical.
