What are carboxyimide-function compounds?

Carboxyimide-function compounds include substances like saccharin, which are used in various applications including food and pharmaceuticals.

How do I know if my product is classified as an imide or an imine?

Check the chemical structure of your product; imides typically contain a carbonyl group bonded to nitrogen, while imines contain a carbon-nitrogen double bond.

What should I do if my product doesn't fit any HS-6 subheading?

If your product doesn't clearly match any HS-6 subheading, consult with a customs broker for guidance on proper classification.

Are there any restrictions on importing saccharin?

Check local regulations, as some countries may have specific restrictions on the import of saccharin due to health regulations.

Can I use HS-4 2925 for all carboxyimide compounds?

No, you must select the appropriate HS-6 code based on the specific compound you are importing.

HS-4 · Heading

2925 — Carboxyimide-function compounds (including saccharin and its salts) and imine-function compounds

Chapter 29: Organic chemicals

Plain-language overview

Use HS-4 2925 when importing carboxyimide-function compounds, such as saccharin or its salts, and imine-function compounds. For instance, if you're bringing in saccharin for use as a sweetener in food products, this is the correct heading to consider.

When deciding between HS-6 lines, note that 292511 specifically covers saccharin and its salts, while 292512 is reserved for glutethimide, a specific pharmaceutical compound. If your product does not fit these categories, you may need to look at 292519 for other imides.

For imine-function compounds, 292521 includes chlordimeform, a pesticide, while 292529 covers other imines and their salts not specified elsewhere. Make sure to identify the specific compound you're importing to select the appropriate code.
