Import Tips

• Verify API 5ST certification and provide mill test reports (MTRs) confirming chemical composition and mechanical properties for stainless steel

• Ensure tubing meets 'of a kind used in drilling' criteria with end connections suitable for oilfield use; misclassification as general pipe common pitfall

• Include hydrostatic test certificates and dimensional compliance docs to avoid customs delays
