Import Tips & Compliance
• Verify the casting material is nonmalleable cast iron via metallurgical certification to avoid reclassification under malleable iron codes
• Include engineering drawings and installation specs in documentation to prove it's a catch basin, not a generic container
• Check local building codes for size and load ratings, as undersized imports may face customs holds for safety compliance
