Electrical wholesale leads the way on ETIM, eCl@ss and BMEcat — yet classification alone never becomes a product page. Where the standard ends, and how a PIM for retailers closes the content gap.
Few trades have their product data house in as good an order as electrical wholesale. While a fashion retailer is still fighting variant Excels and a furniture dealer is manually re-keying PDF catalogs, the electrical world has had mature, machine-readable classification standards for years. ETIM, eCl@ss and BMEcat are the envy of every other industry.
And yet the same electrical wholesaler opens their online shop and finds it full of bare feature tables, half-empty descriptions and product pages no end customer would call helpful. The classification is there. The content isn't. This guide explains why — and where a PIM built for retailers takes over from the standard.
Product data in electrical wholesale is technical, deeply attributed data that industry standards classify very well — but classification alone is not customer-ready content. The electrical trade got its standards right early, and they do real work:
In practice you receive a BMEcat file full of ETIM-classified articles from a big manufacturer, and the technical backbone of your catalog is handled. If you want the deeper breakdown, we wrote a dedicated piece on what GDSN, ETIM and eCl@ss actually are.
Here is the trap the electrical trade falls into precisely because its classification is so good: teams assume that once the ETIM features are in, the product is done. It isn't. An attribute list answers "what is this," not "why should I buy it."
A fully ETIM-classified luminaire might carry 40 clean features — lumens, colour temperature, IP rating, beam angle — and still have:
This is the content gap. Classification is a solved problem; sales content is not. Turning standardized features into readable, differentiated copy is manual work — exactly the kind of task AI enrichment is built to automate.
The ETIM story assumes every supplier plays along. For the big listed manufacturers they do. But most electrical dealers also carry a long tail of accessory brands, niche manufacturers and own-brand products — and those rarely deliver ETIM at all. Instead you get an Excel export, a PDF datasheet, or a feed with attribute names that match nothing in your structure.
So the dealer ends up with two catalogs in one: a pristine ETIM-classified core, and a messy, unclassified longtail that someone has to key in by hand. That mixed reality — clean standard plus standard-less remainder — is the actual daily problem, and it's the same pattern we describe for every trade in the multi-brand retailer overview. The fix is to consolidate and normalize data from multiple suppliers into one structure, whatever format it arrived in.
The same data pattern — strong classification, weak content, a longtail without ETIM — repeats across every part of the assortment:
Productbay is built to sit exactly where ETIM stops. The job is the same three steps that apply across every trade:
Crucially, Productbay does not replace your classification — it complements it. Clean ETIM stays clean; the standard-less longtail gets classified; and every article, standardized or not, gets the sales content the feature list never carried. Productbay is built for specialist retailers running multi-supplier, multi-channel catalogs, and for the electronics side of the business the dedicated PIM for electronics retailers page goes deeper.
What the industry standard delivers — and where a PIM takes over:
| Layer | ETIM/eCl@ss delivers | What Productbay adds |
|---|---|---|
| Classification | machine-readable attributes, product groups | already there — Productbay imports ETIM/BMEcat directly |
| Sales content | — | AI writes customer-ready copy from the attributes |
| Suppliers without ETIM | — | import Excel/PDF and map onto the structure |
| Channels | — | sync to shop and marketplace feeds |
You may already have clean ETIM classification for your core brands — but the longtail and the sales content are still manual. See in 30 minutes how Productbay ingests BMEcat, classifies the rest and writes customer-ready content.
