Import Tips
• Provide NACE MR0175 compliance for sour service if used in refining; documentation prevents reclassification
• Specify OD/ID tolerances in invoices; precision cold-drawing distinguishes from hot-rolled
• Watch for Section 232 tariffs on steel; heat-resisting alloys often qualify for exclusions
