Import Tips & Compliance
• Verify material composition (e.g
• alloy steel) and machining tolerances via certified engineering drawings to confirm classification as gearbox parts
• Include detailed assembly diagrams showing integration with gears to avoid reclassification as general shafts under 8483.10
• Ensure origin certificates for steel components to leverage preferential duty rates under trade agreements
