Import Tips
• Include material test reports (MTRs) detailing precipitation hardening alloy composition to prevent classification as carbon steel
• Document that tubing is not finished for retail sale to avoid set/packaging provisions
• Specify end-use as industrial instrumentation to differentiate from mechanical tubing
