Sector Classification (MDB)

Sector Classification is the system that multilateral development banks use to assign one or more sector labels to every project they finance, indicating which part of the economy the project addresses. These labels appear in project databases and procurement plans and are the primary filter suppliers use when scanning MDB pipelines for relevant opportunities.

What is Sector Classification?

Each MDB maintains its own sector taxonomy, though many are broadly similar and inspired by ISIC-derived categories. The World Bank, for example, classifies projects under major sectors such as Agriculture, Education, Energy, Health, Transport, Water, and Information and Communications Technology, and within each sector there are sub-sector codes for greater precision. ADB and AfDB use comparable sector lists. These sector labels are attached to the project as a whole at the time of board approval and appear in the project's publicly available documentation, including the project appraisal document and the procurement-plan.

Sector classification is distinct from theme-classification, which labels a project by the cross-cutting development themes it addresses (such as gender, climate, governance) rather than the industry sector. Both dimensions appear in MDB project records and can be searched simultaneously. The sector label is the better predictor of what goods, works, and services will be procured, while the theme label signals which safeguard or policy frameworks apply.

Why Sector Classification matters for bidders

A supplier specialising in water infrastructure, renewable energy, or health systems uses sector classification as the first filter when scanning MDB project pipelines for future business. By knowing which sectors are receiving new loan approvals, a firm can anticipate procurement opportunities 12 to 24 months in advance and prepare the relevant qualifications, local partnerships, and expressions of interest before specific tenders are published. Sector-level analysis of award data also reveals which competitors dominate a given sector and at what contract values, informing go/no-go decisions.

FAQ

Does each MDB use the same sector codes?

No. Each bank maintains its own sector taxonomy, though there is significant overlap. The World Bank, ADB, and AfDB all use broadly similar categories derived from international standards such as ISIC, but the specific code values and sub-sector breakdowns differ between institutions.

Is sector classification the same as a NAICS or UNSPSC code?

No. MDB sector classification is an internal project-level label applied by the bank. NAICS and UNSPSC are independent coding standards used in supplier registration and tender notices. MDB sector labels are not directly mapped to NAICS or UNSPSC, though a supplier can manually align its own sector classification to these external standards.

Where can I find the sector classification for a specific MDB project?

MDB project databases are publicly searchable. The World Bank Project database, ADB Projects page, and AfDB project portal all allow filtering by sector. Each project record displays the assigned sector label and links to related procurement notices.
