When should a shipping paper be retained by a shipper?

The requirement for a shipper to retain shipping papers for three years from the date of shipment is based on regulations established to ensure proper record-keeping for hazardous materials. This retention period allows for adequate tracking and safety oversight of shipments containing hazardous materials, providing a reference for investigations, audits, and compliance checks.

Keeping records for three years is considered a standard timeframe that balances accountability with operational efficiency, ensuring that information is available if needed before it is deemed no longer relevant for safety and liability purposes. This timeframe is aligned with the key provisions in hazardous materials regulations that aim to maintain safety and compliance in shipping practices.
