Import Tips
• Provide OEM engineering drawings showing ag/hort mounting compatibility to support classification
• Ensure crankshaft specs match importer's machinery; mismatches lead to end-use verification delays
• Declare exact kW rating precisely; rounding errors trigger audits under power threshold rules
