Drop-N-Tell® 25G Shock Indicators are self-adhesive impact detection devices calibrated to activate at exactly 25G of force. Once triggered, the indicator cannot be reset, creating a tamper-evident visual record that confirms whether a package experienced a qualifying impact event during transit. This non-resettable design ensures that activation evidence cannot be manipulated between shipment and delivery.

The 25G threshold is appropriate for moderately resilient goods that still require impact accountability — products firm enough to tolerate minor handling stress but valuable enough to warrant documented protection. Common applications include electronics distribution, medical device shipping, industrial equipment transit, and any supply chain where impact liability documentation supports claims processing or carrier accountability.

Each indicator features a self-stick backing for direct application to the package exterior and includes warning labels with receiver instructions, eliminating the need for separate documentation inserts. Drop-N-Tell® indicators are available in six G-force ranges to match varying product fragility levels. Cases contain 25 indicators and ship via parcel carrier.
