What is Mil-Spec packaging?

"A United States defense standard, often called a military standard, "MIL-STD", "MIL-SPEC", or (informally) MilSpecs, is used to help achieve standardization objectives by the U.S. Department of Defense." Defined by wikipedia


Sounds official and a little complicated. So we went ahead and created a Cliffsnotes™ version. The following information represents a pared down description of the many elaborate explanations you'll likely find online. 

MilSpec in simple terms is military specifications used to describe the physical and/or operational characteristics of a product, says the Government Accountability Office (GAO). In even simpler terms, the Department of Defense (DOD) defines MilSpec as “military performance specification,” period.

The objective of Mil-Spec is to ensure that items and products meet specific requirements:

  • Total cost of ownership (TCO)
  • Reliability
  • Logistic systems compatibility
  • Manufacturing requirements
  • Testing standards
  • Other defense-related objectives

The GAO notes that mil-spec helps:

  • Protect against contractor fraud
  • Promote greater opportunities for competition among contractors
  • Provide products that can perform in extreme conditions
  • Ensure inter-operability between products

Military Specification + Packaging & Shipping

In addition to the DOD, defense standards are utilized by many non-governmental agencies, this includes packaging and shipping. In the world of packaging and shipping, the physical and/or operational characteristics of a shipment may include, but are not limited to:

  • Bar codin6g
  • Cleaning and drying procedures
  • Cushioning, wrapping, and barrier materials
  • Outer shipping containers
  • Packing levels
  • Preservation methods
  • Preservative materials to be utilized/applied
  • Quantity per unit pack and intermediate pack
  • RFID (radio-frequency identification)

Companies that require or prefer mil-spec packaging for their domestic or international shipments have a variety of options to choose from including:

  • Custom Wood Crates
  • Shipping Containers
  • Heavy Duty Wood Boxes
  • Part Specific Boxes
  • Light Duty Boxes

Many Mil-Specs cover federal requirements for shipping crates, boxes and containers used for domestic and overseas shipping of various products, materials, and supplies.

So, if you’re in the business of requiring Mil-Spec packaging, you’ll likely encounter the following specifications: PPP-B-601, PPP-B-621, MIL-DTL-197K, ASTM-D-6251, ASTM-D-6256, MIL-B-2427, MIL-DTL-2845, ASTM-D-6039, MIL-C-104, and ASTM-D-7478.
