Import Tips
• Q125 requires special high-collapse testing; provide collapse test data in technical file to support classification
• Measure OD precisely—10-3/4 inch is 273.05 mm nominal, must stay within 215.9-285.8 mm band
• Label as 'casing, tubing, or drill pipe' per statistical note; avoid generic 'steel pipe' descriptions
