Import Tips
• Document linkage to wafer slicing saws per statistical notes to prevent misclassification as general industrial parts
• Use stainless steel or Hastelloy certifications for corrosion resistance in coolant applications
• Avoid common pitfall of missing pressure test reports, required for high-precision import clearance
