Import Tips
• Provide end-use certification showing semiconductor application to qualify for potential duty relief programs
• Documentation must include wetted materials (e.g
• PFA-lined) and particle generation specs
• Avoid misclassification as wafer prep equipment (8486); confirm primary function is pumping
