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
