NSN NATO Stock Number + Defense Procurement Protective Case B2B Guide

NATO Stock Number (NSN) is the 13-digit standardized item identification system used by NATO + allied nations (US, UK, Germany, France, Italy, Canada, Australia, etc.) for defense procurement. Below is the 2026 B2B procurement guide covering NSN structure (FSC + NIIN), CAGE code registration, MIL-STD-130 marking, MIL-STD-129 marking + labels, AC/135 cataloging, and protective case correlation.

NSN + NATO物品番号システム

NSN (NATO Stock Number) is the 13-digit standardized item identification number. Used for procurement of parts, equipment, + supplies across NATO + allied nations.

NSN structure: 13 digits total. First 4 digits = Federal Supply Class (FSC) code. Last 9 digits = National Item Identification Number (NIIN). Example: 8115-01-234-5678 (FSC 8115, NIIN 01-234-5678).

FSC (Federal Supply Class): 4-digit code classifying items by supply category. Example FSC codes: 8115 (boxes, cartons, crates), 6230 (electric portable + handheld lighting), 5305 (screws), 1005 (guns through 30mm), 2540 (vehicular furniture).

NIIN (National Item Identification Number): 9-digit unique identifier within an FSC. Structure: 2-digit NATO country code (e.g., 01 = USA, 99 = UK, 02 = Canada) + 7-digit sequential number. NIIN uniquely identifies each part.

NATO Stock Number assignment: Each NATO nation assigns NSN for items manufactured in their country. USA = National Stock Number (NSN) + NATO Stock Number (NSN). Other countries = National Codification Bureau (NCB). NCBs submit new NSNs to NATO Maintenance and Supply Agency (NAMSA).

NSN catalogue (AC/135): NATO Allied Committee 135 (AC/135) maintains NATO Codification System + Allied Supply Chain Group. AC/135 cataloguing rules per ACodP-1 (Allied Codification Publication). Items with NSN catalogued per AC/135 are part of NATO integrated supply chain.

CAGE (Commercial and Government Entity) code: 5-character alphanumeric code identifying suppliers to US/DoD + NATO. Used in NSN records to identify manufacturer. USA = Cage + NCAGE. NATO = Cage + NCAGE.

CAGE registration: Free via CAGE.gov (USA) or NCS (NATO Codification System). Required for suppliers to US DoD + NATO. Self-service registration with validation.

NSN lookup: USA = NSN via FEDLOG (DoD logistics database). NATO = NSN via NAMSA. Public NSN lookup via ISO Group (isogroup.com), parttarget.com, iso-group.com. Free + paid lookup tools available.

Defense Logistics Agency (DLA): USA defense logistics agency managing NSN cataloguing + procurement. DLA contracts for items + manages MIL-STD packaging specifications.

NSN assignment process: (1) Identify FSC. (2) Verify item not already NSN. (3) Submit Item Data via CAGE code. (4) NCB assigns NIIN. (5) Issue NSN = FSC + NIIN. (6) Publish in national + NATO catalogues.

NSN + protective case: Protective case manufacturer assigns NSN when product meets military/defense specification. Customer (DoD, NATO, defense contractor) orders using NSN. Case must comply with MIL-STD packaging + marking requirements.

Defense customer identification: DoD = US Department of Defense. NATO = North Atlantic Treaty Organization. Allied nations = UK MoD, German BAAINBw, French DGA, Italian MoD, Canadian DND, Australian Defence, Japanese MoD.

B2B relevance: For B2B manufacturers exporting to defense customers, NSN assignment + CAGE code registration required for procurement. Items without NSN can be procured via Part Number (PN) but NSN enables NATO supply chain integration.

B2B recommendation: For 2026 B2B orders targeting defense customers, target NSN-assigned + CAGE-coded protective case with MIL-STD-130 + MIL-STD-129 marking, AC/135 cataloguing, IP67 + MIL-STD-810G compliance, FOB Shenzhen/Ningbo/EXW delivery 30-45 days.

MIL-STD-130 + MIL-STD-129 + MIL-STD-2073
