Import Tips
• Provide pressure class markings and ASME B16.5 compliance docs to match exact statistical reporting
• Declare nominal pipe size (NPS) accurately to avoid undervaluation penalties
• Watch for country-of-origin rules; many stainless flanges face additional tariffs from EU or Asian origins
