Import Tips
• Include chemical composition analysis proving stainless steel alloy status per ASTM A312 or API 5DP
• Document tool joint specifications; mismatch can lead to classification as plain tubing under 7304.41
• Avoid bulk packaging confusion—declare as individual lengths to prevent set classification errors
