Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a mixture with solvents for safety/transport
Solutions of chapter 29 compounds in solvents for transport fall under heading 2933 if not constituting normal putting up.
If formulated as a ready-to-use herbicide product
Pesticides in formulations like solutions or suspensions are classified in chapter 38 based on end-use preparation.
If containing an added stabilizer for preservation
Products with stabilizers necessary for transport remain in 2918.99 but may shift subheading if not purely the named acid.

Import Tips & Compliance
• Provide EPA registration documents and purity certificates to verify compliance with pesticide import regulations
• Ensure chemical identity matches exactly with the named compound; impurities over specified limits may shift classification
• Label containers with UN numbers for hazardous material transport and include Material Safety Data Sheets (MSDS)
