National Competitive Bidding (NCB)

National Competitive Bidding (NCB) is the domestically advertised procurement method that multilateral development banks permit for smaller contracts where international suppliers are unlikely to compete, advertised through national channels and conducted in the local language and currency.

What is National Competitive Bidding?

NCB is the lighter counterpart to icb. When a contract financed by a development bank is too small to attract foreign bidders, or when the goods and works are readily available locally, the borrower may advertise nationally rather than internationally. The procedures still follow the bank's core principles, economy, efficiency, transparency, and equal treatment, but the notice runs in the country's official gazette or national procurement portal, documents are in the national language, and prices are quoted in local currency. Eligible foreign firms are usually still allowed to bid if they wish, but the process is not engineered to draw them in. As with ICB, larger NCB contracts may use prequalification and require bid-security, and the opening document is typically an ifb.

The threshold between NCB and ICB is set per country and per bank, based on contract value and the realistic prospect of international competition.

Why NCB matters for bidders

For domestic suppliers in a borrowing country, NCB contracts are often the most accessible entry point into development-bank-financed work, because they run in the local language, currency, and procurement culture you already know. For international firms, NCB is a signal worth reading: it usually means smaller value and a domestically tilted field, so the win comes from local presence, a local partner, or a competitive local cost base rather than global scale. Either way, monitoring national procurement portals as well as the bank notice boards matters, because NCB opportunities may never appear on the international feeds that carry ICB.

FAQ

Can foreign firms bid on NCB contracts?

Usually yes, eligible foreign firms are typically allowed to participate, but NCB is advertised domestically and structured around local bidders, so it is not designed to attract international competition.

What decides whether a contract is NCB or ICB?

The contract value and the likelihood of international interest, measured against thresholds set by the financing bank for that country, determine whether a contract is advertised nationally or internationally.

What language and currency are used in NCB?

NCB is normally conducted in the country's official language and local currency, unlike ICB, which uses an international working language and a hard currency.
