Identification Marking of U.S. Military Property (Item Unique Identification / IUID)
Mandates Item Unique Identification (IUID) marking for all tangible military property delivered to the U.S. DoD under DFARS 252.211-7003. Requires permanent 2D DataMatrix ECC 200 barcodes encoded using ISO/IEC 15434 syntax with human-readable text.
Labels must achieve a minimum verification grade of 1.5 (C) or higher under ISO/IEC 15415. Markings must survive extreme defense environments including salt spray (MIL-STD-810), blowing sand, JP-8 jet fuel immersion, hydraulic fluids, and thermal shock from -55°C to 150°C for the complete operational lifecycle of the weapon system or vehicle.
MIL-STD-130 (IUID) vs. MIL-STD-129 (Military Logistics)
MIL-STD-130 governs permanent Item Unique Identification (IUID) affixed directly to tangible defense property over its entire operational lifecycle. MIL-STD-129 governs the exterior markings on shipping boxes, unit packs, and intermediate shipping containers used during military transit.
MIL-STD-130 / DFARS Pre-Audit Inspector Verification Checklist
Review these 5 critical inspection points before the Authority Having Jurisdiction (AHJ) or field auditor inspects the installation:
ISO/IEC 15434 Syntax Verification
Verify the 2D DataMatrix barcode encodes valid ISO 15434 syntax with Envelope Header `[)>*06<GS>`, Application Identifiers (17V CAGE, 1P Part#, S Serial#), and End-of-Transmission `<RS><EOT>`.
Construct #1 vs. Construct #2 Selection
Confirm whether Construct 1 (CAGE + Serial, unique across enterprise) or Construct 2 (CAGE + Original Part# + Serial, unique within part) is required by the DoD contract.
AIM DPM / ISO 15415 Grade Verification
Ensure the 2D DataMatrix achieves a minimum verification Grade B (3.0) or Grade A (4.0) for cell contrast, axial non-uniformity, and modulation under standard 660nm lighting.
Human-Readable Information (HRI)
Verify that CAGE code, Part Number, and Serial Number are printed in human-readable alphanumeric text adjacent to the 2D DataMatrix for manual verification.
Substrate & Defense Life Survivability
Inspect rating plate material against Skydrol, salt fog (ASTM B117), and weapon clean solvents (Brady B-423, B-428, or B-483A with R6000HF ribbon).

MIL-STD-130 / DFARS Frequently Asked Compliance Questions
What DoD items require MIL-STD-130 IUID marking?
Under DFARS 252.211-7003, IUID marking is mandatory for: (1) All DoD property acquisitions with a unit acquisition cost of $5,000 or more; (2) Mission-essential, serially managed, or sensitive items regardless of cost; (3) Sub-assemblies and components embedded within end-items; and (4) Items for which the requiring activity determines UID is necessary for lifecycle tracking.
What is the difference between MIL-STD-130 Construct 1 and Construct 2?
Construct 1 encodes Enterprise Identifier (CAGE code) and a unique Serial Number that is never duplicated across the enterprise. Construct 2 encodes Enterprise Identifier (CAGE code), Original Part Number, and Serial Number (unique within that part number). Construct 2 is the most widely used format in defense contracting.
What 2D barcode format is required by MIL-STD-130?
MIL-STD-130 requires an ISO/IEC 16022 2D DataMatrix (ECC 200) barcode formatted with ISO/IEC 15434 syntax using Data Format 06 (`[)>*06...`). Standard QR codes and linear 1D barcodes do not satisfy military IUID requirements.
What label material meets MIL-STD-130 for harsh military environments?
Brady B-428 matte silver metallized polyester and B-483A high-tack polyester printed with R6000HF pure resin ribbon are engineered to withstand Skydrol aviation fluid, salt spray fog (ASTM B117), weapon cleaning solvents, and extreme outdoor weather for 10+ years.
