Import Tips
• Include detailed dimensional specs (OD, wall thickness, weight) and material certs in entry docs to confirm casing classification
• Watch for common pitfalls like incorrect grade labeling leading to duty recalculation; stainless must have min 10.5% chromium
• For HPHT wells, provide pressure test records to support P110 rating during customs valuation
