HS Code for Isocyanates
Isocyanates are classified under HS code 292910, which resides within Chapter 29 of the Harmonized System, dedicated to organic chemicals. Heading 2929 covers "Other nitrogen-function compounds," and subheading 292910 specifically identifies isocyanates. These are organic compounds containing the isocyanate functional group (-N=C=O). They are highly reactive and serve as essential raw materials in the production of polyurethanes, coatings, and adhesives. Classification here requires the substance to be a separate chemically defined organic compound, whether or not containing impurities. If the isocyanate is part of a prepared mixture or a prepolymer, the classification may shift to other chapters. The precision of 292910 ensures that these specific nitrogen-function chemicals are tracked accurately for trade statistics and regulatory compliance, particularly given their significance in industrial chemistry and safety regulations. Importers must verify the chemical purity and molecular structure to ensure the product does not fall into a broader category of chemical mixtures or finished plastic resins.
Products Included
- Methyl diphenyl diisocyanate (MDI)
- Toluene diisocyanate (TDI)
- Hexamethylene diisocyanate (HDI)
- Isophorone diisocyanate (IPDI)
- Pure organic isocyanate monomers
Common Misclassification
Isocyanates are often misclassified under HS code 390950 if they have already been reacted into polyurethanes. Another common error is using HS code 382499 for chemical mixtures; however, if the product is a chemically defined isocyanate, 292910 takes precedence. Misclassification also occurs with isocyanides (carbylamines), which are distinct from isocyanates.
FAQ
What is the HS code for Isocyanates?
The HS code for isocyanates as separate chemically defined organic compounds is 292910.
Are polyurethane resins classified under this code?
No, polyurethane resins in primary forms are classified under HS code 390950. HS code 292910 is strictly for the isocyanate chemical precursors.
