Import Tips
• Verify compatibility with cleanroom standards (ISO 14644) and provide manufacturer specs confirming use in heat exchange units; obtain end-user certificates for semiconductor machinery to avoid reclassification
• Common pitfall: inadequate documentation of non-domestic use leading to duty disputes
