HTS US: 2929.XX.XXXX
Description
Heading 2929 encompasses chemical compounds that contain nitrogen atoms involved in various functional groups other than amines or nitriles. The primary focus of this heading is on isocyanates and other related nitrogen-containing compounds used extensively in the chemical industry, especially in the manufacture of polyurethanes and specialty chemicals.
These compounds are categorized into two main groups within the heading:
- Isocyanates: Organic compounds containing one or more isocyanate groups (-N=C=O), which are highly reactive intermediates in polymer production.
- Other nitrogen function compounds: Various nitrogen-containing chemical substances that do not fall under isocyanates but feature nitrogen in notable functional groups.
Code Hierarchy
- Section VI: Products of the Chemical or Allied Industries (Chapters 28-38)
- Chapter 29: Organic Chemicals
- Heading 2929: Compounds with other nitrogen function
- US HTS Code (10-digit):
2929.XX.XXXX– The final digits specify the exact compound or mixture.

What is NOT Classified Here?
The heading excludes nitrogen compounds classified in other chapters or headings such as:
- Amines and their derivatives (classified under other headings of Chapter 29).
- Nitriles and their derivatives (covered elsewhere in Chapter 29).
- Pharmaceutical products containing nitrogen compounds, which are classified under Chapter 30.
- Inorganic nitrogen compounds which fall outside organic chemical classifications.
Notes
- Chemical Industry Use: Many of the compounds under this heading serve as critical intermediates in polyurethane production, adhesives, coatings, and elastomers.
- Regulatory Considerations: Importers must ensure compliance with chemical safety regulations such as TSCA (Toxic Substances Control Act) in the U.S. and provide proper documentation regarding chemical composition and use.
- Tariff and Duty Rates: Duty rates vary depending on the exact subheading and compound. Some specialty isocyanates may be subject to specific tariff treatments.
