Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is ethylenediamine itself, not its salt
Ethylenediamine (the free base) is specifically listed in subheading 2921.21, while its salts fall under the residual subheading 2921.29.
If the product is a formulated mixture containing other additives
Prepared chemical products not elsewhere specified are classified in heading 38.24 when they contain additional components beyond the pure salt.

Import Tips & Compliance
• Provide the CAS number (333-18-6) and purity certificate on shipping documents to facilitate CBSA clearance
• Confirm the salt is not put up in measured doses or for retail sale, which would trigger Section Note 2 reclassification
• Check if the product qualifies for duty relief under the Chemicals and Plastics Duties Remission Order if used in manufacturing
