CPC (Central Product Classification)

The Central Product Classification (CPC) is the United Nations system for classifying all tangible and intangible products, covering goods, services, and assets, in a unified hierarchy that links directly to industry-activity codes and to customs classification, giving international procurement a common reference for defining what is being bought.

What is CPC?

CPC organises every product into sections, divisions, groups, classes, and subclasses. Goods subclasses cross-reference hs-codes-harmonised-system chapters to maintain consistency with customs data, while service subclasses link to isic-international-standard-industrial-classification activity classes to connect what is sold with the industry that produces it. This cross-linking is why CPC is the backbone of international trade-in-services statistics and General Agreement on Trade in Services (GATS) schedules: countries describe their service-sector commitments using CPC codes. In procurement, CPC appears in World Trade Organization Government Procurement Agreement (GPA) coverage schedules, where each party lists the services it opens to international competition using CPC references, making it the gateway code for understanding which service categories are legally open to foreign suppliers.

Unlike unspsc, which is optimised for purchasing systems, or cpv-common-procurement-vocabulary, which is designed for EU contract notices, CPC is a statistical and treaty-level reference rather than a day-to-day tender filter.

Why CPC matters for bidders

Suppliers bidding on services contracts in markets covered by the WTO GPA will encounter CPC references in the coverage annexes that define which services are open to international competition. Knowing your CPC subclass lets you verify whether your service category is covered by the GPA in a given country, which in turn determines whether you have WTO-backed rights to participate on equal terms with domestic firms. For firms entering new markets, cross-referencing their offering against the CPC codes in a country's GPA schedule is a quick eligibility check before investing in qualification or local partnerships.

FAQ

How does CPC differ from UNSPSC?

UNSPSC is a purchasing classification used by procurement systems to route tender notices to registered suppliers; CPC is a statistical and treaty-level classification used to define service-sector commitments in trade agreements and international statistics.

How many levels does CPC have?

CPC uses five levels: section (one digit), division (two digits), group (three digits), class (four digits), and subclass (five digits), with the most specific subclass typically cited in trade schedules.

Which version of CPC is current?

CPC Version 2.1 is the current release maintained by the UN Statistics Division. Some WTO schedules still reference Version 1.0 or 1.1 because coverage commitments were made under earlier versions; checking the treaty annex confirms which version applies.
