Import Tips
• Verify classification as semiconductor manufacturing equipment via statistical note (a)(i) with detailed technical specs and end-use certificates
• Include material composition (e.g
• high-temperature alloys) and OEM compatibility docs to avoid reclassification as general machinery parts
