Import Tips
• Aerospace alloys require enhanced documentation like FAA-equivalent certifications; prepare for additional CBP scrutiny
• Verify slab flatness and surface condition in manifests—excessive processing may reclassify as semi-finished
• Use precise weight declarations; overweight shipments often face valuation disputes
