Import Tips & Compliance
• Include purchase orders or contracts specifying 'line pipe for oil/gas pipelines' to support classification over general tubes
• Conduct hydrostatic test certification; U.S. customs often audits pressure ratings for pipeline suitability
• Avoid bulk packaging confusion—declare wall thickness and yield strength to distinguish from structural tubes
