Import Tips & Compliance
• Include technical specs showing threaded drill connections and hollow bore for air/fluid flow
• Avoid common pitfall of classifying as oilfield tubing (7306) without drilling end-use proof
• Label with alloy content; high-strength steel per note (a) may affect quotas or duties
