Import Tips
• Submit technical drawings showing actuator integration and pressure ratings suitable for semiconductor cleanrooms
• Label with exact material composition (e.g
• 316L stainless steel) to meet corrosion resistance standards
• Watch for undervaluation pitfalls; declare full value including actuator to avoid penalties
