Import Tips
• Include operating manuals showing automatic regulation mode to distinguish from manual regulators
• Label as 'automatic manostat' on commercial invoice; avoid generic 'pressure regulator' to prevent 8481 reclassification
• Check for FCC compliance if incorporating electronic controls for U.S. entry
