Seal Requirements

New Seal Requirement Effective - Mid 2023

In order to reduce industry thefts, Union Pacific will require theft-deterrent or barrier seals (minimum 1/8 cable or bolt seal) on intermodal shipments beginning in mid 2023. This requirement is to provide the highest level of protection from unauthorized entry into intermodal containers or trailers during all levels of logistic transportation from the shipper. The required seals are designed to prevent entry to the intermodal container or trailer with ordinary seal removal techniques, such as bolt cutters. The minimum seal requirement of 1/8 cable or bolt seal will add another layer of theft protection along with delaying and preventing easy access to shipments during transport.

Union Pacific's policy on seal requirements can be found in Intermodal Terms & Conditions, Section F. In order to be properly sealed, a seal must be placed through the hasp furthest to the left on the right door. If the hasp in this location is inoperable, it is permissible to utilize the right hasp on the right door. Any container or trailer not sealed in accordance with these requirements may be rejected.

Theft-Deterrent Barrier Seals

Theft-Deterrent or Barrier seals provide the highest level of protection from unauthorized entry into intermodal containers or trailers. These seals are designed to prevent entry to the container with ordinary seal removal techniques, such as bolt cutters. Union Pacific recommends the use of a Theft-Deterrent or Barrier seal on all high-value loads.

Security Seals (Bolt Seal and Cable Seals)

Security seals are constructed of metal or metal-clad cable, and are designed to provide minimal resistance to unauthorized entry into the container. These seals typically require bolt cutter for removal.

Indicative Seals (Tin or Plastic Seals)

Indicative seals are only used to indicate whether or not a container has been opened. This type of seal does not provide any protection from unauthorized entry into the container. Indicative seals should only be used on loads that don’t require protection from theft, or contamination.
