Import Tips
• Include NIST-traceable material test reports for advanced composites to satisfy customs engineering review
• Verify ITAR exemption status; aircraft turbine parts often require export license equivalents for import
• Avoid misdeclaration as 'industrial turbine part' which shifts to 8411.99.10 and different duties
