Import Tips
• Provide detailed specs showing hub-spigot compatibility with cast-iron soil pipe per industry standards like CISPI 301
• Ensure country-of-origin markings are cast into the fitting to meet US customs permanence requirements
• Avoid bulk packaging mislabeled for other uses, as it could lead to reclassification under general fittings headings
