Import Tips
• Include ASTM A179 certification and hydrostatic test results to prove suitability for superheaters
• Measure and declare precise OD; tubes approaching 38.1mm risk reclassification to higher diameter subheadings
• Avoid bulk packaging misdeclared as raw material; specify finished tube form for correct heading
