Import Tips
• Verify material composition certification to confirm 'other materials' excluding stainless steel, as alloy content affects classification
• Provide documentation proving use in semiconductor manufacturing to avoid reclassification under Chapter 84 machinery provisions
• Check for pressure ratings and ensure FDA or cleanroom compatibility labels if for ultrapure applications to prevent customs holds
