eCl@ss

While both are classification standards, eCl@ss is a horizontal, cross-industry standard covering almost all product groups, whereas ETIM is a vertical standard specifically focused on the electro-technical, HVAC, and construction sectors. eCl@ss uses a 4-level hierarchy, while ETIM uses a flatter structure focused on technical features for wholesalers.

eCl@ss ensures that product data is interoperable between different systems like ERP, PIM, and e-shops. It allows B2B buyers to search for products using standardized technical attributes, which is essential for automated procurement and reducing manual errors in complex industrial supply chains.

Implementing eCl@ss in a PIM system begins by mapping your internal product categories to the standard four-level eCl@ss hierarchy. Once categorized, you must assign the relevant properties and values defined by the standard to each product record. This structured mapping allows for automated data exports that are compatible with the ERP and procurement systems of your international B2B customers.

Adopting eCl@ss allows manufacturers to speak a universal technical language that is recognized globally by industrial marketplaces and procurement software. It significantly reduces the manual effort required for data exchange and minimizes errors in technical specifications. By using standardized properties, manufacturers improve their product findability and ensure their data is ready for Industry 4.0 applications.

While eCl@ss is cross-industry, it is particularly beneficial for sectors with complex technical requirements such as mechanical engineering, automotive, medical technology, and construction. These industries rely on precise property descriptions like voltage, dimensions, or material composition to ensure component compatibility. Companies operating in highly regulated or international markets find it essential for maintaining data consistency across different regions.

Yes, eCl@ss is specifically designed to facilitate automated electronic data interchange (EDI) and digital procurement between business partners. Since every product class and property has a unique, language-neutral ID, procurement systems can automatically match supplier catalogs with buyer requirements. This automation eliminates manual data entry, speeds up the purchasing cycle, and reduces the risk of ordering incorrect technical parts.

The code uses a hierarchical four-level structure to organize products. The first two digits signify the Segment (e.g., Engineering). The next two are the Main Group (e.g., Fastening). The third pair is the Subgroup (e.g., Screw), and the final two identify the Product Class. This granularity ensures that every item is categorized specifically enough for procurement systems to recognize it instantly, regardless of the language used by the supplier or buyer.

eCl@ss operates on a paid licensing model managed by the eCl@ss Association. Users typically choose between a 'Basic' license for individual versions or a 'Pro' license that provides access to all versions and languages. While there is an upfront cost, the investment pays for itself by eliminating the need for custom mapping between different customer systems and reducing manual data entry errors in international trade and industrial procurement.

This task usually falls to Master Data Managers or Technical Product Managers who understand the physical specifications of the items. In larger industrial firms, a dedicated Data Steward oversees the mapping process to ensure consistency. These individuals work closely with the IT department to ensure the codes are correctly exported from the PIM or ERP system into the electronic catalogs sent to B2B customers and marketplaces.

The most common alternatives are UNSPSC, which is widely used in North America for procurement, and ETIM, which focuses specifically on the electro-technical and construction sectors. While UNSPSC is flatter and more focused on spend analysis, eCl@ss provides much deeper technical attributes. Some companies also use GPC (Global Product Classification) within the GS1 framework, though it is more prevalent in retail and consumer goods than in heavy industry.

A frequent mistake is mapping products only to the category level while ignoring the 'Properties' or 'Values.' Without these attributes, like thread size or voltage, the classification loses its technical utility for automated engineering. Another error is failing to plan for version updates; since the standard evolves, using a static mapping that doesn't account for new releases will eventually lead to data rejection by modern B2B procurement platforms.

You should use official 'Release Notes' and 'Transaction Files' provided by the association to track changes between versions. Best practice involves maintaining a mapping table that links your internal SKUs to specific eCl@ss versions. When a new version is released, use automated delta files to identify which of your categories have been moved, renamed, or split, allowing you to update your PIM system without manual re-classification of the entire catalog.
