Import Tips
• Submit detailed technical datasheets proving power rating and piston engine type during customs entry
• For marine use, prepare IMO Tier compliance docs; common pitfall is classifying as aircraft engine
• Avoid bulk shipments without individual serial numbers to prevent valuation disputes
