Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported with integrated cutting blades
Tool holders with saw blades classify as saw tool parts rather than work holders.
If for engine lathes or similar
Jigs for general precision sawing (non-semiconductor) fall under standard machine tool parts.
If with automated optical alignment
Sensor-integrated positioning jigs classify as measuring or checking appliances.

Import Tips & Compliance
• Include wafer thickness tolerance specs (<1 micron) in invoices to prove semiconductor-specific design
• Obtain advance ruling if jig adaptable to non-semiconductor saws to prevent 8487 reclassification
• Ensure diamond wire compatibility certification for customs verification
