Import Tips

• Verify equipment is specifically for semiconductor boule processing to qualify under statistical provisions; provide detailed technical specs and end-use certificates

• Common pitfall: misclassification as general machinery without wafer prep documentation

• Ensure FDA or export control compliance if handling high-purity materials
