Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If based on synthetic polymers other than rubber
Non-rubber polymer mastics fall under the 'other' subheading within 3214.90.
If asphalt or bituminous content dominates
Chapter notes exclude bituminous mastics, directing them to heading 2715.
If imported as bulk unsaturated rubber resin, not finished putty
Raw unsaturated synthetic rubber polymers classify under Chapter 39 if not compounded into mastics.

Import Tips & Compliance
ā¢ Label products clearly as 'glaziers' putty' to distinguish from general caulks during customs review
ā¢ Provide manufacturer specs confirming rubber base to avoid reclassification to bituminous mastics (excluded by Chapter notes)
ā¢ Check state regulations for VOC limits; non-compliant imports may face detention
