Import Tips

• Verify alloy steel composition meets 'other alloy steel' criteria via mill test certificates; ensure API 5CT certification for L-80 grade

• Common pitfall: misclassifying as carbon steel if chromium exceeds thresholds

• Provide end-use declaration for drilling to avoid anti-dumping scrutiny
