Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If resin binder predominates over graphite
Prepared binders for foundry molds classify under 3824 if non-graphite primary.
If pre-formed into millstones or grinding wheels
Finished abrasive articles shift to Chapter 68.
If petroleum-based binder formulation
Petroleum pitch mixtures classify under Chapter 27.

Import Tips & Compliance
• Include furnace process specifications confirming paste end-use; prevents chemical mixture classification
• Phenol-formaldehyde resin content requires VOC emissions documentation for certain ports
• Test for free crystalline silica <1% to avoid respirable dust hazmat requirements
