Why ETIM Classification Matters for Electrical and HVAC Catalogs
Picture this. You’re a catalog manager staring at twelve tabs of spreadsheets, PDFs, and supplier portals. One vendor lists voltage as 230 V, another as 0.23 kV, a third says “230VAC” in the title and nowhere else. Half your new SKUs include specs in German and Italian. You’re trying to map everything to ETIM, one feature at a time, across thousands of products while distributors ping you about missing attributes and rejected imports. ETIM classification is required.
You translate, guess, normalize, and rework. Then you do it again for the next distributor with slightly different expectations. That’s the grind of manual ETIM mapping in electrical and HVAC catalogs.
Now imagine a different flow. You drop your data and documents into a system like Classifast.com. It detects languages, normalizes units, and suggests the right ETIM class with the features most likely to apply. It flags anything uncertain so you only review edge cases. Then it validates against the ETIM model and exports clean, structured data to your PIM or ERP.
That is the promise of automation: higher accuracy, real scale, and a lot less labor.
Across ETIM use cases, teams have reported major wins when they standardize product data. One manufacturer scenario reported up to a 70% reduction in time to onboard new products to distributor systems, and technical attribute errors that “virtually disappear” once standardized fields are in place. Another real-world case described task turnaround times shifting from hours to minutes after aligning product data for ETIM-focused distribution workflows. Consistent structure reduces chaos, and automation reduces grind.
A day in the life: manual mapping pain you might recognize
You gather datasheets from five suppliers. One calls the product a “socket outlet with switch”, one says “Schuko Steckdose mit Schalter”, one just says “SO-SW”. You spend ten minutes per SKU searching for the right ETIM class in the viewer, only to find the set of features is close but not perfect. Then the units don’t match—millimeters vs inches, Celsius vs Fahrenheit.
Multiply that by a launch of 1,200 SKUs. That’s weeks of repetitive work and a long tail of rework as partners reject inconsistent fields.
The business case for standardization
ETIM classification gives everyone a shared language for technical data. Manufacturers can supply one structured spec set. Distributors can import without retyping. And your e-commerce team can build precise filters that actually help customers find the right part instead of scrolling for an hour.
Understanding ETIM: The Foundation of Product Data Standardization
What is ETIM classification?
ETIM classification is a standardized, multilingual way to describe technical products using predefined product classes with a fixed set of features, allowed values, and measurement units. It enables manufacturers and distributors to exchange consistent product data across systems and markets.
Inside the ETIM model: entities, identifiers, and multilingual design
ETIM is a product data model with clear building blocks:
- Product Groups: High-level buckets for managing related classes.
- Product Classes (EC): The heart of ETIM. Each class represents a specific product type and comes with a defined list of features.
- Features (EF): Technical characteristics that describe products in the class (alphanumeric, numeric, range, or logic).
- Values (EV): Predefined choices used with alphanumeric features.
- Units (EU): Standardized measurement units used with numeric and range features.
- Synonyms: Extra search terms per language linked to a class.
All these objects use language-independent identifiers. The codes like EC, EF, EV, and EU do not change by language. Labels and synonyms, on the other hand, are language-dependent, so the same class can be displayed with local naming without breaking system-to-system exchange.
ETIM vs UNSPSC vs eCl@ss vs GS1
| Standard | Primary Focus | Best Use Cases |
|---|---|---|
| ETIM | Technical attributes for electro-technical and HVAC | Technical catalogs, e-commerce filters |
| UNSPSC | Spend categorization and procurement | Procurement analytics, high-level categorization |
| eCl@ss | Cross-industry classification with properties | Industrial MDM, engineering catalogs |
| GS1 GPC | Retail product classification | Retail supply chain, barcoding ecosystems |
The Complete ETIM Classification Process
- Prepare: Consolidate product sources (ERP, supplier feeds, PDFs). Detect language for titles and documents, resolve duplicates, and normalize basic units.
- Map: Assign each SKU to the correct ETIM product class. Extract attributes from descriptions and align them to the class’s features (EC, EF, EV, EU).
- Validate: Check each record against ETIM constraints. Are required features populated? Are you using official EU unit codes?
- Export: Produce a structured file (CSV, BMECat, or API payload) for your PIM/ERP.
- Publish and syndicate: Push to e-commerce, marketplaces, and distributors.
- Review and improve: Track exceptions and rework to tighten your extraction rules.
Automating ETIM Classification: How Classifast Delivers Accuracy and Efficiency
Whether you build in-house or use a specialized platform, effective automation follows a clear conveyor: ingest, parse, classify, validate, export.
Classifast is a high-performance web application designed specifically for this task. Built with FastAPI and modern web technologies, it provides instant classification for industry standards like ETIM, UNSPSC, NAICS, ISIC, and HS codes. By using advanced semantic search, Classifast understands the technical context of your product descriptions, moving beyond simple keyword matching to deliver fast, intelligent categorization.
How the Classifast Pipeline works:
- Ingest & Parse: The system reads your CSVs or PDFs, detects languages, and runs OCR to pull out structured attributes.
- Extract and Normalize: Attributes are mapped to ETIM features (EF) by meaning. Numeric values are automatically converted to ETIM units (EU).
- Semantic Classification: The engine proposes the top matching ETIM classes (EC) with confidence scores. High-confidence matches can be auto-assigned, while edge cases are routed to a human reviewer.
- Validation & Export: Every SKU is checked against ETIM version constraints before being exported as a PIM-ready file.
Best Practices and Common Pitfalls
Prepare high-quality data upfront
- Inventory SKUs: Define canonical IDs before you begin.
- Unit Dictionary: Map all supplier abbreviations to ETIM EU codes immediately.
- Clean Titles: Ensure titles include differentiating specs like voltage or range.
Troubleshooting Common Issues
- Ambiguous Descriptions: If Classifast gives a low-confidence score, enrich the title with more technical specs.
- Mixed Units: Enforce normalization to ETIM EU codes at the start of the pipeline to prevent numeric feature rejection.
- Version Mismatch: Treat ETIM versions like software releases; regression-test affected classes before a bulk update.
Frequently Asked Questions
Q: What is ETIM, and why does it matter?
A: ETIM is a standardized, multilingual way to describe technical products. It ensures that a “socket” in one system is exactly the same “socket” in another, regardless of language.
Q: How does Classifast help with ETIM?
A: Classifast uses semantic search to instantly find the correct ETIM codes for your text inputs. It automates the unit normalization and feature extraction that normally takes hours.
Q: How do I handle multilingual catalogs?
A: Anchor your records on language-independent codes (EC, EF, EV, EU). You can then display local labels in your PIM while the underlying data remains globally compatible.
Conclusion: Taking the Next Step Toward Modern Catalog Excellence
ETIM gives you the structure; automation via Classifast.com gives you the speed. By moving from manual mapping to a semantic search-driven workflow, you can reduce onboarding cycles by up to 70% and virtually eliminate technical attribute errors.
Start with a pilot of your top 20 classes. Let the model do the heavy lifting of unit normalization and class selection, so your team can focus on the high-value edge cases.
