How to Identify NAVSEA Standard Items
Identification of NAVSEA standard items involves understanding their coding and labeling systems.
NSN (National Stock Number)
Most NAVSEA standard items are assigned an NSN, a 13-digit number used internationally to identify standardized material items.
Format: 1234-00-567-8901
- The first four digits denote the Federal Supply Class (FSC).
- The next two digits often specify the country of origin or specific classification.
- The remaining digits are unique item identifiers.
Navy Item Control Numbers (NICN)
Some items are tracked via NICN, which provides detailed control information for inventory purposes.
Labels and Markings
Standard items usually feature markings indicating compliance with NAVSEA standards, including:
- NSN or part number
- Manufacturer's code
- Quality assurance markings
- Date of manufacture

Procurement and Supply Chain for NAVSEA Standard Items
Efficient procurement of NAVSEA standard items is vital for maintaining naval operations without delays.
Authorized Vendors and Suppliers
Only qualified vendors approved by NAVSEA or the Defense Logistics Agency (DLA) can supply standard items. Vendors must adhere to strict quality assurance protocols.
Ordering Process
- Identification of the required item via NSN or part number.
- Submission of purchase requests through approved channels.
- Verification of vendor qualification and certification.
- Delivery and inspection of the items upon receipt.
Inventory Management
Naval vessels and facilities maintain robust inventory systems to track standard items, ensuring availability and reducing downtime.

Maintenance and Replacement of NAVSEA Standard Items
Proper maintenance of standard items ensures long service life, safety, and operational effectiveness.
Inspection and Testing
Regular inspections identify wear, corrosion, or damage. Testing ensures components meet performance standards before reuse.
Replacement Guidelines
- Follow the manufacturer's or NAVSEA's replacement schedules.
- Use approved standard items to replace worn or damaged components.
- Document all replacements for maintenance records.
Obsolescence Handling
When certain standard items become obsolete, NAVSEA issues updates, and suppliers develop replacements that meet or exceed previous specifications.

Importance of Compliance and Standards
Adherence to NAVSEA standard items' specifications is mandatory for all contractors and maintenance personnel to ensure interoperability and safety.
Relevant Standards and Specifications
- MIL-SPEC (Military Specifications)
- NAVSEA Drawing and Technical Standards
- ASTM and ISO standards for materials and testing
Consequences of Non-Compliance
- Increased risk of system failure
- Safety hazards
- Increased maintenance costs
- Potential legal and contractual repercussions
