Methylamine Stabilized with Ammonia
Methylamine stabilized with ammonia is a solution of methylamine containing ammonia as a stabilizer to prevent corrosion during transport. Under Chapter Note 1(f) of Chapter 29, products of heading 29.21 with an added stabilizer necessary for preservation or transport are classifiable in the chapter. Therefore, this product falls under tariff item 2921.11.00 as methylamine, provided the ammonia does not render it particularly suitable for a specific use.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the ammonia content is significant enough to make it a mixture of amines
A mixture of methylamine and ammonia, if not merely a stabilizer, could be classified under other acyclic monoamines.

Import Tips & Compliance
• The presence of ammonia as a stabilizer must be clearly indicated on the safety data sheet and commercial invoice
• Ensure the stabilizer is only for preservation and not to alter the product's use, as this could affect classification
• Check if the mixture is subject to any Canadian transportation of dangerous goods (TDG) requirements
