Summary of Operations
Interagency Mail offers express mail pickup and delivery by providing effective and efficient customer service to State of South Carolina government entities. We serve more than 600 agencies throughout the state with overnight or next day delivery of interagency mail, packages and bulk items. In addition, we ship time-sensitive materials such as payrolls, laboratory samples, medicines, library books and other unique packages which other mail carriers will not handle.
Rates are calculated by weight and reflect a substantial cost savings as compared with express mail rates of the United States Postal Service, UPS, Federal Express and other carriers.
Our current rates are:
First Class: $1.96/lb
Bulk Class: $0.44/lb
Laboratory Class: $1.77/lb
Other Class (Library Books, packages): $0.85/lb
In addition, there is a minimum shipping fee of $30/month for all active shipping sites. This only comes into effect if a site ships less than $30 of mail in a month.
