Import Tips
• Provide foundry certification confirming nonmalleable composition to distinguish from gray or ductile iron variants
• Declare exact inner diameter and wall thickness as these affect pressure class ratings required by plumbing codes
• Ensure packaging prevents damage during transit, as cast iron is brittle; use wooden crates for bulk shipments
