Import Tips & Compliance
• Provide engineering drawings showing round head and square neck to distinguish from hex bolts and support classification
• Confirm imperial/metric equivalence (1/4" = 6.35mm >6mm) with caliper measurements to prevent diameter disputes
• Include proof of same-shipment entry for bolt/nut sets; mismatched shipments risk duty reassessment
