Browse and source aerospace and defense components using exact 9-digit National Item Identification Numbers (NIIN), including in-stock numbers like 01-417-4215, 17-104-2027, 27-036-9172, 37-514-8102, and 41-001-6331. Every part in our NIIN catalog is cross-referenced for accurate fitment and traceable back to its manufacturer.
A NIIN is the 9-digit identifier at the core of the NATO Codification System. The first two digits are the National Codification Bureau (NCB) code 00 or 01 for U.S.-issued items followed by a 7-digit item sequence. Paired with a 4-digit Federal Supply Class, a NIIN forms the complete 13-digit NSN, so if you're working from a supply category rather than an exact number, that's the faster starting point.
Our NIIN inventory spans airframe structures, avionics hardware, and turbine components for commercial and civil aviation, alongside tactical vehicle, naval, and military aircraft parts sourced to applicable defense standards. AOG support is built in, with expedited sourcing and cross-referencing to reduce downtime when a part is needed immediately.
Once you've confirmed the NIIN you need, request pricing through our Instant RFQ form, catalog RFQ button, live chat, or phone, most quotes are returned within 15 minutes during business hours, with AOG support available 24/7/365.
