Import Tips
• Verify sound pressure level (SPL) certification to confirm classification as signaling apparatus, not musical instruments
• Include safety compliance docs like UL or CE for industrial use to avoid reclassification
• Check for piezo vs air-powered to distinguish from simpler buzzers under 8531.80.10
