Import Tips & Compliance
• Verify compliance with ASTM C878 standards for load ratings and ensure markings for traffic or non-traffic use
• Provide engineering certifications and material test reports (MTRs) to confirm plastic composition meets subheading polymer rules
• Avoid misclassification as general construction plates; specify manhole end-use in entry documentation
