Import Tips
• Provide foundry certifications proving cast iron composition to distinguish from ductile iron under other subheadings
• Label with pressure class (e.g
• Class 125) to aid customs in verifying 'other' fitting status
• Avoid bulk packaging without individual specs to prevent misclassification as parts
