Domestic Preference

Domestic preference is a price adjustment that multilateral development bank procurement rules permit a borrowing country to apply when evaluating bids, giving locally produced goods or domestic contractors an advantage over international competitors equivalent to a stated percentage of the evaluated bid price, without requiring international bidders to be disqualified.

What is Domestic Preference?

Under World Bank procurement regulations and similar frameworks at other MDBs, a borrowing country may apply a domestic preference margin when evaluating bids for goods manufactured in the country or for works contracts where domestic contractors compete. For goods, a preference of up to 15 percent is commonly permitted: when comparing a domestically manufactured good against an imported equivalent, the evaluator adds 15 percent to the customs-inclusive cost of the imported good before comparing it with the domestic price. For works contracts, a similar margin may be applied to the evaluated cost of bids from domestic firms. If the domestic bid is still higher after applying the preference margin, the international bid wins; if the domestic bid falls within the margin, the domestic supplier wins even though its headline price is higher.

Domestic preference applies only under international competitive bidding, where domestic and international suppliers compete in the same pool. It is not the same as national competitive bidding, which is a separate method that restricts the pool to domestic firms entirely. The specific margin and the goods and works categories to which it applies are set out in the bidding documents.

Why Domestic Preference matters for bidders

For international firms, domestic preference means that winning a bid in a country that applies the margin requires a price lead large enough to absorb it. An international supplier quoting against a domestic manufacturer must price its offer more than 15 percent below the domestic price on a customs-duty-inclusive basis to win the evaluation. Failing to account for this margin in competitive analysis leads to bids that are technically compliant but lose on evaluation. For domestic firms and joint ventures, understanding whether a project applies domestic preference can be the difference between being competitive and being priced out by lower-cost international suppliers, making it worth checking the bidding documents carefully before deciding whether to bid alone or in a joint venture.

Example

A World Bank-financed power generation project in Nigeria invited bids for transformers under international competitive bidding. Nigeria's implementing agency applied a 15 percent domestic preference margin for locally manufactured goods. A Nigerian manufacturer quoted USD 4.2 million. A Chinese manufacturer quoted USD 3.8 million CIF Lagos, with import duties bringing the landed cost to USD 4.0 million. After applying the 15 percent preference, the evaluator compared USD 4.2 million against USD 4.6 million (4.0 million plus 15 percent), and the Nigerian manufacturer won even though its headline price was higher.

Frequently Asked Questions

Does every MDB project apply domestic preference?

No. The application of domestic preference is optional and must be explicitly stated in the bidding documents. Many projects do not apply it, particularly where the domestic manufacturing base is limited or where the financing institution has not approved its use for the specific loan.

Does domestic preference exclude international bidders?

No. Domestic preference is a price adjustment applied during evaluation, not a disqualification rule. International firms remain eligible to bid and win; they simply need a larger price advantage to overcome the margin applied in favour of domestic suppliers.

Is domestic preference the same as local content requirements?

No. Domestic preference is an evaluation tool applied at bid assessment. Local content requirements (such as Aramco's IKTVA programme or ADNOC's In-Country Value programme) are ongoing contractual obligations that require the winning supplier to source a proportion of its inputs locally throughout contract execution. Both can apply to the same project but operate at different stages.
