What is ETIM, explained

What is ETIM in one sentence?  It’s the European Technical Information Model, an international classification standard that gives electrical, HVAC, plumbing and construction businesses a shared way to describe technical products. Two trading partners using ETIM can exchange product data without arguing whether a circuit breaker should be called a "miniature circuit breaker" or an "MCB". This explainer covers what ETIM is, what problem it solves, how the structure works, and why distributors in technical verticals rely on it.

What ETIM stands for

ETIM stands for European Technical Information Model. It is a classification standard for technical products, governed by ETIM International, an independent body with member organisations in more than 20 countries. The standard started in the Netherlands in the 1990s, when electrical wholesalers needed a common way to describe the products they all sold. It has since expanded into HVAC, sanitary, building automation, tools and several adjacent verticals.

The "European" in the name is now historical. ETIM is used in Australia, Canada, the United States, South Africa and across most of Europe. Local-language versions exist, with the underlying class and feature IDs the same everywhere, so a translated value in Swedish points to the same attribute as the English original.

What problem ETIM solves

Before ETIM, every distributor classified products in their own way. A junction box might sit under "Enclosures, outdoor" at one wholesaler and "Boxes, plastic" at another. A manufacturer with 500 distributor customers maintained, in effect, 500 catalogues. Updates to a single product had to be applied 500 times, in 500 different schemas.

The result was painful for everyone in the chain. Buyers comparing products across distributors had no way to filter on the same technical attribute. Procurement teams had to translate between supplier and internal codes. Cross-border trade, the entire point of a European standard, added another layer of language and classification mismatch on top.

ETIM removes that overhead by publishing a single agreed model. Every participant uses the same class IDs, the same feature IDs, and the same allowed value lists. A miniature circuit breaker is class EC000049 wherever you are, with the same features attached. Whether it is sold as "Leitungsschutzschalter" or "MCB", the underlying structure is identical.

How ETIM works

ETIM has four building blocks worth knowing:

Product classes are categories of similar products. Each class has a unique ID, for example EC000049 for a miniature circuit breaker. Classes cover technical products specifically, so a class exists for "Cable, low voltage power" but not for "T-shirt". The standard contains thousands of active classes, with new ones added in each major version.

Features are the attributes attached to a class. Each class has its own set of features that matter for that product type. A miniature circuit breaker has features like rated current, number of poles, tripping characteristic and breaking capacity. A pipe fitting has features like material, nominal diameter and connection type. Features are shared across classes where it makes sense, so "material" on a pipe and "material" on a bracket reference the same feature ID.

Feature values are the allowed values for a feature. Some features take numeric values with units, like rated current at 16 A, 20 A or 25 A. Others use enumerated lists, like material values of brass, copper, steel or aluminium. The values are also IDs, not free text, so a value translated into Polish points to the same canonical value as the English one.

The class hierarchy groups related classes into broader categories. EC covers electrical, EH covers HVAC, EM covers building automation, and so on. Inside each major group, related classes sit together, which makes it easier for a category manager to find the right class without searching the whole tree.

ETIM in the wider ecosystem

ETIM does not exist on its own. A few adjacent standards travel with it:

ETIM MC (Modelling Classes) extends classification with geometry data for BIM workflows. Architects and contractors using building information modelling tools need to place a product into a 3D model, so MC adds dimensional and geometric attributes on top of the standard ETIM class.

ETIM IXF is the data exchange format published by ETIM International. It is a defined XML schema for transferring classified product data between systems.

BMEcat is the most widely used delivery format for ETIM-classified data. It is a separate XML standard for product catalogues, with extensions that carry ETIM classes and features inline.

ETIM also complements rather than replaces other classification standards. GS1 focuses on identification, the GTIN barcode, and supply-chain data. UNSPSC is a higher-level commodity classification used in procurement and spend analysis. ETIM operates at the technical attribute layer. A product can carry a GTIN, a UNSPSC code and an ETIM class without conflict.

Who uses ETIM

ETIM started in electrical wholesale, which is still the largest user community. Wholesalers and distributors in this sector have spent two decades building data exchange around the standard, and most large electrical manufacturers maintain ETIM-classified product data as a default.

The standard has expanded into adjacent verticals where catalogues are large, technical and cross-border. HVAC distributors use ETIM for heating, ventilation and cooling components. Sanitary and plumbing wholesalers use it for taps, valves, pipework and fittings. Construction materials distributors use it for the technical end of the catalogue, particularly for products that need BIM data.

Manufacturers selling into these verticals classify their products in ETIM to make it easier for distributor customers to onboard the catalogue. Without ETIM, the manufacturer is back to maintaining a separate format per buyer.

ETIM’s structure in practice

A concrete example helps. Take a miniature circuit breaker, the kind found in residential consumer units.

The product gets classified into ETIM class EC000049, miniature circuit breaker. That class has a defined set of features. A category manager filling in the data captures values for:

• Rated current: 16 A
• Number of poles: 1
• Tripping characteristic: B
• Breaking capacity: 6 kA
• Type of mounting: DIN rail

Each value is an ETIM-defined value ID, not free text. A search engine sitting on top of this data can now offer faceted filtering on rated current, breaking capacity and tripping characteristic without any per-product configuration. A procurement system can pull a comparable specification across three manufacturers without normalising attribute names.

If the same product is sold in a country where the local distributor uses ETIM 9 instead of ETIM 8, the class and feature IDs are typically the same, though new features may exist in the newer version. Mapping between versions is covered in the ETIM 8 vs ETIM 9 comparison.

The ETIM journey

ETIM is governed by ETIM International, with national member organisations contributing to the model. New classes and features are proposed through the national chapters, debated, and rolled into major releases.

Major versions are published periodically. ETIM 7 was the working version through the late 2010s. ETIM 8 brought a significant set of new classes and broader vertical coverage. ETIM 9 is the current major version, with further class additions and refinements aligned with BIM and sustainability requirements.

Countries adopt new versions on their own timelines. A distributor on ETIM 8 trading with a supplier on ETIM 9 needs to manage a mapping layer between the two. This is the most common reason ETIM migrations turn into a project rather than a routine upgrade.

For teams planning an ETIM rollout from scratch, the basics of how to implement ETIM cover the standard sequence: catalogue audit, class mapping, feature population, validation, and integration with downstream systems. The ETIM data mapping software you pick will determine how much of this is manual and how much is automated, particularly for the class mapping and feature extraction steps where AI tooling now plays a significant role.

Key takeaways

• ETIM is an international classification standard for technical products, used by electrical, HVAC, plumbing and construction distributors.
• It provides a shared model of classes, features and feature values so trading partners can exchange product data without translating between private taxonomies.
• The surrounding ecosystem includes ETIM MC for BIM geometry, ETIM IXF as an exchange format, and BMEcat as the most common delivery container.
• Major versions, ETIM 7, 8 and 9, are released by ETIM International, with countries adopting on their own timelines.
• ETIM complements rather than replaces GS1 (identification) and UNSPSC (commodity classification). A product can carry all three.

Where to go next

If you’re working with ETIM data, the bottleneck is rarely understanding the standard. It’s the time it takes to classify catalogues, extract feature values from supplier documents, and keep mappings current across versions. ETIM data mapping software addresses that work directly, particularly for distributors managing tens of thousands of SKUs across multiple supplier feeds.
