Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing sulfur directly linked to carbon
Chapter notes exclude sulfur-carbon compounds from 2931; glufosinate's phosphorus-carbon linkage defines its heading.
If insecticidally-formulated despite herbicide use
Pesticide formulations classified by principal use; herbicide glufosinate goes to 3808.93, not insecticides.

Import Tips & Compliance
• Dispersant content must be <5% with proof it's solely for transport/stability to maintain pure compound status
• Fumigation certificates required for bulk powder imports to prevent microbial contamination
• Batch testing for heavy metals mandatory due to phosphorus compound sensitivity
