A Mechanic is informed by his Chief Inspector the certification paperwork was incorrect for the Receiving Inspection documentation on their CRJ-700 Horizontal Stabilizer Trim Actuator (HSTA) from a foreign repair vendor.

Narrative

Jun/08 I received a Horizontal Stabilizer Trim Actuator into the carrier part tracking system. On Dec/08 I was informed by Chief Inspector that the certification paperwork was incorrect. Efforts are ongoing to get the proper certification documents from the vendor. Manufacturer in ZZZ is carrier's approved vendor. However; manufacturer in ZZZ does not do the repair; they send the item to manufacturer in ZZZ! After the repair is done; the item is returned to ZZZ. The item is then sent to the end user. On arrival at ZZZ the item is entered into the system by the receiving clerk. The item is then received the carrier part tracking system by the Receiving Inspector. I entered the required data into carrier part tracking system using the 8130 issued by manufacturer in ZZZ1. I did not realize that manufacturer was working under 2 addresses. The document issued by manufacturer in ZZZ had the certificate of conformity statement X'ed out and the 'Maintenance Release Issued' checked 'No.' Working with the belief that I had a 'Valid' 8130; I certified the part and released it for issue. The part was subsequently installed on Aircraft X.
