Methacrylamide with MEHQ Stabilizer
Methacrylamide stabilized with 100-400 ppm MEHQ (monomethyl ether hydroquinone) to prevent polymerization during storage and transport. The stabilizer is permissible under Chapter 29 note (f) as necessary for preservation, so the product remains classified as pure methacrylamide under 2924.19.00.

Import Tips & Compliance
• Document the stabilizer concentration (100-400 ppm) to show it is within permissible limits for preservation
• Ensure the stabilizer does not alter the product's end-use suitability, as this could affect classification
• Verify that MEHQ is not restricted under Canadian chemical control lists
