3-6.4 Drop-and-Pick Trailer Retrieval

Once the unload process is complete, mailers must retrieve their trailer(s) within 1 business day. A shipper’s repeated failure to remove empty trailers in a timely manner will result in cancellation of D&P privileges and could also result in demurrage charges. The Postal Service is not responsible for any demurrage or detention charges incurred by anyone participating in the D&P appointment program.
