Import Tips
• Include NACE MR0175/ISO 15156 certification for sour service to support classification and safety compliance
• Provide joint length and weight specs; heavy wall variants must still meet drill pipe criteria
• Avoid common pitfall of importing with plastic caps—declare as pipe, not packaged goods
