What is MIL-STD-130? Specifications, Markings and Requirements for Military Standard 130

In the complex world of military logistics and supply chain management, precision and accountability are paramount. At the heart of these operations lies MIL-STD-130, a critical military standard that governs how items are identified and tracked throughout their lifecycle.

This standard, officially titled “Identification Marking of U.S. Military Property,” is more than just a set of rules—it’s a comprehensive system designed to enhance efficiency, reduce errors, and improve overall asset management for the Department of Defense (DoD).

MIL-STD-130 applies to a wide range of military property, from small components to large equipment, and impacts everyone involved in the defense supply chain, from manufacturers and suppliers to logistics personnel and end-users.

By establishing uniform methods for marking items with unique identifiers, including both human-readable information and machine-readable data, MIL-STD-130 enables seamless maintenance, accountability and tracking of military assets.

What is MIL-STD-130?

Military Standard 130 (MIL-STD-130) contains a detailed set of requirements and specifications for identification marking of U.S. military property. The standard practice involved in MIL-STD-130 has undergone some revisions, including MIL-STD-130N, which was released in December 2007 and MIL-STD-130N w/ Change 1, which was released in November 2012.

MIL-STD-130 is just one of several standards developed by the United States Government to guide individuals and organizations both within and outside of the Department of Defense (DoD) through uniform engineering and technical requirements for military-unique or modified commercial processes, procedures, practices, and methods.

As per the MIL-STD-130N w/ Change 1 Foreword, the DoD “continues to provide evolving clarification, increased insight, guidance, and marking criteria regarding implementation of machine-readable information (MRI) for identification marking of U.S. military property and automatic data capture. MRI provides a valuable tool for life-cycle asset management from acquisition through manufacture to distribution and final disposition.

However, the use of MRI may not be suitable or adequate for every identification marking need. The application of free text item identification marking in combination with or in lieu of MRI is still necessary for many end users of the identified item.”

The foreword also states, “As with product designers, simply stating that items produced under a contract shall be marked per MIL-STD-130 is not sufficient. They must clearly state what identification marking is required, to include the specific item unique identification (IUID) provisions as applicable, and that development of specific item marking requirements be based on the criteria provided in this standard.”

Other military compliance standards include requirements such as MIL-STD-129.

MIL-STD-130 and UID

So, what does MIL-STD-130 mean for you? It’s important to know that there are complex item marking requirements involved in complying with MIL-STD-130, and that it can be daunting for military prime contractors and their subcontractors to understand all of them.

A particular type of marking within MIL-STD-130 is Item Unique Identification (IUID), commonly referred to as UID (unique identifier) which when specified requires all military contractors to place specific markings on their equipment. The government calls for unique and specific numbers to be assigned to government-owned and government-purchased tangible equipment, in accordance with established rules and guidelines as set forth by MIL-STD-130.

The UID compliant marking must be applied to the asset or directly marked on the asset for its lifecycle. The number associated with the UID marking is the unique item identifier, or UII, which is designed to be globally unique.

UID tags will satisfy a wide range of applications, from tactical applications with zero-reflection requirements, to applications requiring extreme sand and gravel resistance. Camcode provides mark engineering services, durable label design and manufacturing services to ensure compliance with MIL-STD-130 regulations, and offers UID registration. 

Camcode is one of the few companies that also offers on-site marking installation services for hassle-free UID compliance.

4 Key Components of MIL-STD-130

MIL-STD-130 specifies several critical elements that must be included in item identification marking. Understanding these components is essential for proper implementation:

1. Unique Item Identifier (UII)

The UII is the cornerstone of MIL-STD-130 marking. It’s a globally unique and unambiguous identifier that remains constant throughout an item’s lifecycle. The UII typically consists of:

• Enterprise Identifier (usually a CAGE code)
• Serial number
• Part number or batch/lot number

2. Data Matrix Symbol

A 2D barcode is required to encode the UII and other essential information. This Data Matrix symbol must:

• Be machine-readable
• Meet specific quality standards (minimum “B” grade in verification)
• Remain readable throughout the item’s lifecycle

3. Human-Readable Information

Alongside the Data Matrix, human-readable text must be included. This typically contains:

• Item name or part number
• Serial number
• Enterprise Identifier
• Original design activity identification

4. Permanent Marking Method

The standard requires that markings be permanent and durable. Acceptable methods include:

• Laser engraving
• Dot peen marking
• Chemical etching
• Durable labels (for specific applications)

The chosen method must withstand environmental conditions and cleaning procedures without degradation.

Compliance and Verification

Ensuring compliance with MIL-STD-130 is crucial for contractors and suppliers working with the Department of Defense. The standard requires rigorous verification processes to confirm the accuracy and integrity of identification markings. Here are key aspects of compliance and verification:

Verification Process

All UID labels and markings must undergo a verification process to ensure they meet the required standards.

This process includes:

1. Checking the data content for accuracy and completeness
2. Verifying the quality of the 2D Data Matrix barcode
3. Ensuring the human-readable information matches the encoded data

Barcode Quality Requirements

The 2D Data Matrix barcode must meet specific quality criteria

• Achieve at least a “B” grade in verification tests
• Be permanent and durable
• Withstand environmental conditions and cleaning procedures
• Remain readable throughout the item’s lifecycle

Verification Tools

Specialized equipment is necessary for proper verification.

• Verifiers: These tools are essential for checking both the data content and the quality of the 2D Data Matrix barcode. They provide a comprehensive analysis of the marking.
• Scanners: While useful for reading the data, scanners cannot verify the quality of the barcode and are not sufficient for full compliance checks.

Documentation and Record-Keeping

Maintaining accurate records is a critical part of compliance.

• Keep detailed logs of verification results
• Archive compliance reports for potential audits
• Ensure all documentation is readily available for DCMA inspections

Regular Inspections

To maintain ongoing compliance:

• Conduct periodic audits of marking elements
• Perform regular quality checks on newly produced labels or markings
• Stay updated on any changes or updates to the MIL-STD-130 requirements

Data Management

Effective data management is crucial for MIL-STD-130 compliance.

• Create and maintain accurate item data
• Use a centralized data management system
• Ensure data is accessible and secure
• Follow established standards and protocols for data sharing with the DoD

By adhering to these compliance and verification practices, contractors and suppliers can ensure their products meet the stringent requirements of MIL-STD-130, avoiding potential rejections or delays in the supply chain.

MIL-STD-130 and UID

So, what does MIL-STD-130 mean for you? It’s important to know that there are complex item marking requirements involved in complying with MIL-STD-130, and that it can be daunting for military prime contractors and their subcontractors to understand all of them.
