Import Tips & Compliance
• Document the vacuum melting process and the resulting purity levels in the technical data sheet, as this supports classification under 7202.93.00
• Ensure the product is in a primary form (e.g
• lumps) and not further worked into articles
• If the product is imported for a specific end-use (e.g
• pipeline steel), include a letter of intent from the end-user to facilitate customs clearance
