Import Tips & Compliance
• Provide detailed manufacturing process documentation proving the item is a casting (e.g
• investment or sand casting) rather than wrought or forged
• Include material test reports (MTRs) confirming titanium alloy composition per Chapter 81 notes (less than 99% titanium but predominant)
• Avoid misclassification as unfinished forgings; common pitfall is lacking evidence of casting method
