Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If adipic acid instead of malonic
Different acyclic dicarboxylic acids have specific subheadings within 2917.19.
If carbonic acid derivative
Inorganic carbon compounds exclude from Chapter 29 per exclusion note 2(d).
If when anti-dusting agent exceeds identification limits
Excess additives change from pure compound to chemical mixture per note 29(g).

Import Tips & Compliance
• Use 25kg fiber drums with PE liner to meet UN packaging standards for Hazard Class 8
• Include manufacturing process validation showing no halogenated impurities to avoid derivative classification
• For FCL shipments, ensure proper segregation from bases/ammonia in container
