Import Tips
• Provide evidence of mechanical recording mechanism (drum/pen system) to distinguish from digital non-recording barometers
• Include charts or photos of recording output in import docs to support classification over general pressure gauges
• Check for restrictions if containing mercury components, requiring EPA declarations
