Import Tips
• Demonstrate humidity recording via charts or digital output logs to avoid reclassification as non-recording hygrometers
• Specify sensor type (hair/capacity) in invoices; capacitive types may face electronics scrutiny
• For wireless models, include FCC compliance docs for radio frequency components
