Import Tips

Label shipments clearly as 'oil well casing with couplings' to match HTS 'imported with coupling' requirement

Provide collapse and burst test data in documentation; critical for proving drilling-grade quality

Check for anti-dumping duties on certain steel origins; file scope rulings if applicable
