TransGuardian was founded in 2005 by Jim Moseley, an expert in high-value shipping programs with decades of experience developing international solutions for some of the world’s largest logistics companies.

In August 2018, TransGuardian’s business operations were acquired by Jewelers Mutual Group to further develop its JM Shipping Solution™ platform. The entire TransGuardian team has joined Jewelers Mutual and, in addition to Jim, directors Madlene Moseley and Randy Miller will provide operational and technical expertise, respectively.

Together, the combined team looks to deliver additional enhancements in the future while providing the same great service today.

In addition to offering the same superior technology and logistics expertise prior to the acquisition, service centers continue to operate in the New York and Los Angeles Diamond Districts.

The platform remains completely free to use, does not require any quotas, and is open to everyone.
