Import Tips
• Document steering mechanism integration to prove propulsion function over simple fluid conveyance
• Obtain material test reports for seawater resistance, as customs may inspect for marine-grade alloys
• Avoid bulk packaging; ship with assembly instructions to maintain 'engine part' status vs. generic fittings
