FMS Third-Party Transfers
When FMS equipment reaches industry
A step-by-step method for non-US companies that repair, integrate or hold equipment their government bought through Foreign Military Sales — the consent the government must obtain, and the company’s part. A government-to-government channel, distinct from DCS licences and agreements.
What this guide settles
- FMS is a government-to-government channel: the State Department authorizes third-party transfers of FMS-origin items through PM/RSAT; DDTC handles items bought commercially
- Under the LOA, a company that repairs, integrates or stores the equipment is a third party — “agent” means freight forwarder only — unless it is a prime contractor identified in the LOA and contracted by the US Government
- The purchasing government submits the request; where a private-entity request is required, the company signs assurances and its government provides the COPE layer
- Other uses and disposal need consent too; FMS items moved to the CCL can still need it; a DCS TAA never authorizes possession of FMS hardware
