Import Tips
• Include detailed grade specs (e.g
• P-110 yield strength) and API monogram to substantiate drilling-specific use
• Measure and document actual OD precisely; customs may inspect physically for >406.4mm compliance
• Avoid pitfalls by not mixing with production tubing; clear invoices specifying 'casing for drilling'
