Import Tips
• Provide detailed chemical composition analysis proving nonalloy steel (carbon content limits) to distinguish from alloy grades
• Include threading specifications (e.g
• BTC or EUE) in invoices, as they confirm drilling-specific design
• Avoid common pitfalls like classifying based on weight per meter alone; focus on OD and seamless nature
