HS-4 · Heading
2920 — Esters of other inorganic acids of non-metals (other than of hydrogen halides) and their salts, their halogenated, sulphonated, nitrated or nitrosated derivatives
Chapter 29: Organic chemicals
Plain-language overview
Use HS-4 2920 when importing or exporting esters of inorganic acids of non-metals, such as thiophosphoric esters like parathion or phosphite esters like dimethyl phosphite. For instance, if you're shipping parathion-methyl for agricultural use, this is the code to apply.
When determining the correct HS-6 line under 2920, consider the specific type of ester. For example, 292011 is for thiophosphoric esters including parathion, while 292019 covers other thiophosphoric esters not including parathion. Knowing the exact chemical composition is crucial for correct classification.
If your product is a phosphite ester, you’ll need to choose between lines like 292021 for dimethyl phosphite or 292022 for diethyl phosphite. If your phosphite ester doesn’t fit these descriptions, you may need 292029, which covers other phosphite esters not elsewhere classified.
For esters of other inorganic acids, 292030 is appropriate for substances like endosulfan. If your product doesn’t fall into the previous categories, check 292090, which includes other esters and derivatives not classified under thiophosphoric or phosphite esters.
