Import Tips

Include FRA loading guides and sound level test data; noise regulations vary by import destination

Verify tank pressure test certificates (typically 7 psi) as proof of leak-tight construction

Use specialized heavy-lift flatbed containers; declare gross weight accurately for bridge toll compliance
