NSCC2 (NATO supply classification code)

NSCC2 stands for NATO supply classification code. NATO's glossary of acronyms and abbreviations (AAP-15) lists the term under that expansion, and it identifies the code used to classify an item of supply within NATO's supply-classification system. The entry is published in the NATO glossary of acronyms and abbreviations.

In NATO's current explanatory materials, the same element is written NSC, short for NATO Supply Classification Code. The NSC is the four-digit "Group and Class" portion of a NATO Stock Number (NSN). It sorts an item into a supply group and class, with NATO giving examples such as generators and aircraft engines. Both names point to the same classification function inside the NATO Codification System.

What the four-digit NSC identifies

NATO's NATO Codification System booklet describes the NSC as the first component of an NSN. It has four digits and is also called the Group and Class. The code does not name one specific part. It places the item in a category of supply, so that items of a similar kind sit together in the same group and class.

Where the NSC sits inside a NATO Stock Number

An NSN has three parts, according to the same NATO booklet:

• the NSC, a four-digit code for group and class
• a two-digit Nation Code
• a seven-digit Item Identification Number

The Nation Code and the Item Identification Number together form the NIIN. The NSC therefore comes first and describes the category, while the NIIN identifies the individual item within the codification record. Reading an NSN from left to right gives the classification first, then the country of the codifying bureau, then the item itself.

The NATO Codification System behind the code

NATO describes the NATO Codification System (NCS) in its NCS fact sheet as a system for consistently naming, describing, classifying, and uniquely identifying equipment, components, and military-system parts. Classification is one of those four functions, and the NSC is the code that carries it. Because the system is shared among participating nations, an item classified under one nation's codification process carries the same structure as items codified elsewhere.

Canada's place in NATO codification

NATO's historical NATO Logistics Handbook identifies Canada's National Codification Bureau code as 21. In an NSN, that two-digit value is the Nation Code position. Canada's participation in NATO codification is the reason Canadian-codified items carry that identifier alongside the NSC and the Item Identification Number.

What NSCC2 means for a supplier bidding on Canadian public contracts

Department of National Defence opportunities are published on CanadaBuys, so defence-related suppliers will find them there. If a solicitation identifies goods by NATO Stock Number, the first four digits are the NSC, the group and class of the item. Knowing that structure helps a bid team read an NSN correctly and confirm that the item described matches the category being requested.

The term NSCC2 itself is a NATO glossary abbreviation. In explanatory material and in NSN references, expect to see it written as NSC. Check each solicitation's requirements for how items must be identified, and follow the instructions in the tender documents.
