UID identification is recognized as a preferred standard for tracking products and parts. Based upon an item-unique identification code, or nameplate, these UID nameplates possess unique features that help to identify and track a variety of products, parts, and supplies from acquisition throughout their entire lifetime. All suppliers to the U.S. Department of Defense are required to undergo a UID registration process. This UID registry is essential not only for product traceability, but also for cost effective business management and consumer safety.

An approved supplier, or manufacturer, must pass certain requirements prior to receiving approval for UID registration. MIL-STD-130 regulates the specifications of this identification standard. According to these specifications, each product should be marked with UID labels. MIL-STD-130 covers all compliance details needed for the registry and identification marking.

Approved methods of UID marking

All products are directly marked or affixed to a UID affiliated approved tag. As for direct marking processes, programmable stylus indenting, inkjet printing, and laser etching are the most common choices. Products that include separate nameplates and tags must follow MIL STD 130 specifications. UID specifications regarding nameplates are summarized below:

• Both metals and non-metallic materials are approved for UID nameplates. Aluminum and stainless steel are the most recommended substrate materials for UID nameplates. Polyester labels can be used as non-metallic nameplates.

• Nameplates are to be affixed on the product with a strong adhesive. The labels must last for the entire lifetime of a product. As such, nameplates have to undergo a variety of chemical and environmental tests. Tags can be used if a product has less space to incorporate a nameplate. In that case, the tags have to provide the necessary information.

• Some approved marking processes include; laser marking, programmable indent marking, industrial inkjet printing, embossing, indenting, stamping, tagging, and labeling.

• MIL STD 130 states the importance of UID verification. In this process the printed data is checked for compliance. Vision verification equipment and barcode readers are used to scan and verify the accuracy of the printed data. Apart from MIL STD 130, the encoded data must follow specifications as contained in ISO15415 and AS9132.

• During the UID registry process, a supplier must provide company details, product type specifications, the net weight of the product, product value, and various other data. Human readable information should be provided as detailed in MIL STD 130 specified nomenclature.
