Import Tips
• Submit spline profile drawings and hob specifications to prove gear family classification
• Label as 'gear cutting' not 'spline milling' to prevent reclassification; include DIN/AGMA standards reference
• Watch for undervaluation penalties; provide comparable sales data for used/refurbished units
