Import Tips
• Reference the exact ASTM F3125 spec in invoices and provide proof of Grade A325 equivalence to prior A325
• Use HTSUS ruling requests for new F3125 markings to confirm classification
• Avoid common pitfall of declaring as 'hex bolts' without structural notation, risking reclassification
