NCB1 (national codification bureau)

NCB1 is the abbreviation NATO uses for national codification bureau. The bureau is responsible for national codification and acts as its country's point of contact with the NATO Codification System (NCS). NATO's official glossary of acronyms and abbreviations lists the entry as "NCB1 - national codification bureau" and gives the French equivalent as BNC, "bureau national de codification" (AAP-15 glossary).

The term belongs to NATO's logistics and codification vocabulary. The NCS gives member and partner nations a common method for classifying and identifying supply items, including the assignment and maintenance of NATO Stock Numbers (NSNs). The national codification bureau is the organization that applies that method inside its own country (NATO Codification System booklet).

What a national codification bureau does in the NATO Codification System

A national codification bureau is the central national contact for having items codified. NATO describes the bureau as responsible for the day-to-day operation of the NCS within its country, on behalf of the national defence force and industry. It codifies items manufactured in its country, whether those items are intended for national defence forces or for international customers (NATO Codification System booklet).

Bureaux provide codification services to national military organizations, foreign defence organizations and industry using the NCS. NATO also states that the individual bureaux are the sole agencies for codification matters within the NCS framework (NCS fact sheet). In practice, this means codification questions are directed to the bureau and not to NATO itself.

How NCB1 is written: notation and the French equivalent

NATO's codification publications also use NCB as the abbreviation for National Codification Bureau. The "1" in NCB1 is part of NATO's terminology notation. It distinguishes the glossary entry from the abbreviation written simply as NCB. Both refer to the same type of organization.

• English: national codification bureau (NCB1 in the NATO glossary, NCB in codification publications)
• French: bureau national de codification (BNC)

Readers who meet "NCB" in a codification document and "NCB1" in a glossary can treat them as the same concept. NATO also maintains an official terminology database, NATOTerm, for checking how terms are defined and used (NATOTerm).

ACodP-1 and the responsibilities of bureaux, users and contractors

The rules that govern the NCS are set out in NATO's Allied Codification Publication ACodP-1. The publication defines the responsibilities of national codification bureaux, users and contractors. Each participating nation implements the publication's rules through its own bureau, and each bureau is responsible for applying and harmonizing those rules nationally (ACodP-1).

This structure explains why the bureau sits at the centre of codification work. NATO sets a common standard, and the national bureau is the body that carries it out for defence authorities and for industry in that country. NATO also offers e-learning material on the codification system for those who need a closer look at the process (NATO codification e-learning).

What NCB1 means for a supplier bidding on Canadian public contracts

NCB1 is a NATO term, and it points to the national body that handles item codification. If a solicitation for defence or supply work refers to codification, NATO Stock Numbers or the NCS, the national codification bureau is the central national contact for having items codified, and NATO states that bureaux provide codification services to industry.

The specific obligations on a supplier come from the solicitation itself. Bid teams should read the tender documents and any referenced clauses to see what codification information is required and when. Understanding the bureau's role helps a team ask the right questions about item identification before a bid is submitted.
