Import Tips

Provide ASTM A53/A106 or equivalent structural grade certifications with impact testing if required

Clearly mark as 'structural pipe' vs pressure pipe on documentation to guide proper end-use classification

Bundle in standard lifts with protective end caps to prevent damage affecting wall thickness specs
