Import Tips

Provide detailed specifications confirming dissipation rate <1W and unmounted status to avoid reclassification as mounted devices

Use ESD-protected packaging and include material safety data sheets for hazardous substances compliance

Verify country of origin documentation as many wafers originate from sensitive supply chains
