Import Tips
• Include thread specification (e.g
• NPT, BSP) and pressure ratings in commercial invoice to confirm classification
• Test for dezincification resistance if for potable water; common pitfall is failing US EPA lead leaching rules
• Bundle with installation instructions but declare as individual fittings, not sets, to avoid parts/set reclassification
