This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the masterbatch contains additional flame retardants or carriers beyond the named ester
Other chemical preparations not elsewhere specified may apply when the product is a multi-component mixture.
If the product is a compounded plastic in primary form with the ester as a minor additive
Polymers in primary forms are classified in Chapter 39 when the plastic is the essential character.

Import Tips & Compliance
• > Clearly state the concentration and chemical identity of the active ingredient on shipping documents to support classification under 3824.92.00
• If the masterbatch is mixed with polymers or other additives, verify whether it remains a chemical preparation or becomes a plastic article
• Check if the product requires registration under Canadian chemical management regulations
