HS-6 · Subheading
292910
Nitrogen-function compounds; n.e.c. in chapter 29, isocyanates
Heading 2929 — Nitrogen-function compounds, n.e.c. in chapter 29
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 292910 when importing or exporting isocyanates, which are key chemicals in the production of foams, coatings, and adhesives. For example, shipments of toluene diisocyanate (TDI) fall under this code.
This code specifically covers nitrogen-function compounds classified as isocyanates, distinguishing them from other nitrogen compounds like amines or nitriles found in nearby codes. For instance, HS-6 292911 covers carbamates, which are different from isocyanates.
When dealing with isocyanates, it's important to note their hazardous nature and the regulations surrounding their transport. This code applies to various forms, including liquid and solid isocyanates used in industrial applications.
If you're unsure about classification, consider the specific chemical structure and intended use of the product. For example, while HS-6 292910 includes isocyanates, HS-6 292919 covers other nitrogen-function compounds that do not fit this category.

- What types of products are classified under HS-6 292910?
- HS-6 292910 covers isocyanates like toluene diisocyanate, methylene diphenyl diisocyanate, and hexamethylene diisocyanate, used in foams and coatings.
- Are there special regulations for shipping isocyanates?
- Yes, isocyanates are considered hazardous materials, requiring compliance with specific packaging, labeling, and transport regulations.
- How can I determine if my product is an isocyanate?
- Check the chemical structure; if it contains the isocyanate functional group (-N=C=O), it likely falls under HS-6 292910.
- What is the difference between isocyanates and carbamates?
- Isocyanates contain the isocyanate functional group, while carbamates are esters of carbamic acid, classified under a different HS code.
- Can I import isocyanates for manufacturing?
- Yes, but ensure you comply with all safety and regulatory requirements for hazardous materials.
- What packaging is required for shipping isocyanates?
- Isocyanates must be shipped in UN-approved containers, clearly labeled as hazardous materials, and comply with local regulations.
- What are common uses for isocyanates?
- Isocyanates are commonly used in the production of flexible and rigid foams, coatings, adhesives, and sealants.
- How do I classify a new isocyanate product?
- Review the chemical structure and intended use, and consult with a customs broker if needed for accurate classification.
