Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the seal is presented as a part of an air compressor of heading 84.14
Parts of air or vacuum pumps and compressors are classified in heading 84.14 when they are identifiable as such.
If the seal is made of vulcanised rubber other than hard rubber
Rubber seals are excluded from Section XVI and classified in Chapter 40.

Import Tips & Compliance
• Ensure the fluorocarbon elastomer is not classified as vulcanised rubber under Chapter 40, as that would exclude the seal from this heading
• Provide the CBSA with technical specifications showing the seal's mechanical function
• If the seal is for a compressor of heading 84.14, verify whether it is a part of that machine under heading 84.14
