The directories that actually matter
| Source | Coverage | Contact quality | Cost | Best for |
|---|---|---|---|---|
| VDMA member directory | Machinery & plant engineering | High - membership implies a real, established operating company | Free to search | Capital equipment, machine builders |
| Trade fair exhibitor lists | Sector-specific, current | Highest - named staff with roles | Free | Finding the person, not the company |
| Wer liefert was / Europages (Visable) | Very broad B2B | Medium - self-submitted | Free tier plus paid | Initial discovery and long lists |
| Kompass | Broad, international | Medium | Free tier plus paid | Cross-border comparison |
| Industrystock | Components and niche industrial | Medium | Free | Hard-to-classify parts |
| Handelsregister | All registered companies | Legal data only, no sales contacts | Small per-document fee | Verification, never discovery |
| Chamber of commerce (IHK) | Regional | High, but regionally limited | Free / low | Regional clusters |
| Germany Trade & Invest | Official trade promotion | High | Free | Market entry and introductions |
Turning a listing into a real contact
A directory entry is a lead, not a contact. The gap between the two is where most sourcing projects stall.
Find the Impressum, not the contact form
German commercial websites are legally required to publish an Impressum carrying the registered address, register number and managing directors. It is the most accurate page on any German company's site, and it usually reveals a direct email domain pattern.
Target the function, not the inbox
Enquiries to info@ routinely go unanswered. Address the Vertrieb (sales) or, for technical products, the Anwendungstechnik (application engineering) function. Where a named export manager exists, use the name.
Write the enquiry the way a German engineer reads it
Lead with the technical specification, the quantity and the required delivery date. Company introductions belong at the end. A vague "please send your catalogue and best price" is the single most common reason a German manufacturer does not reply.
Send it in German where you can
Response rates to German-language enquiries are materially higher, particularly at Mittelstand companies under roughly 200 employees. Even a short German covering paragraph above an English specification changes the outcome.
Verify before you disclose
Before sending drawings, volumes or pricing, confirm the company in the Handelsregister and check the Bundesanzeiger filing history. Our GmbH verification guide covers the exact sequence.
What a usable supplier record should contain
If you are building your own database rather than renting one, these are the fields that determine whether it is still useful in two years:
| Field | Why |
|---|---|
| Registered name + HRB/HRA number + court | The only stable identifier. Trading names change; register numbers do not |
| Named contact, role, direct line | Generic inboxes decay fastest |
| Capability in your terms | "5-axis, up to 1,200 mm, Inconel" beats "precision machining" |
| Certifications held and expiry dates | ISO 9001, IATF 16949, AS9100, PED, ATEX as relevant |
| Minimum order value and typical lead time | Eliminates mismatched suppliers before the RFQ round |
| Date last verified | Any record older than 18 months should be re-checked before use |
A realistic sourcing sequence
- Define the part or machine precisely - material, tolerance, volume, certification, delivery date.
- Build a long list of 20-40 candidates from VDMA plus the relevant trade fair exhibitor directory.
- Filter to 8-12 on capability fit and size match. A €40,000 order at a €400 million manufacturer will not get attention.
- Verify each in the Handelsregister and Bundesanzeiger; drop anything with filing gaps.
- Send a specification-led RFQ to the remaining shortlist, in German where possible.
- Expect 40-60% to respond within two weeks. Non-response is usually a capacity signal, not rudeness.
- Compare quotes on total landed cost and documentation scope, not unit price - see our guide on evaluating German supplier quotes.

Frequently asked questions
What is the best database of German industrial suppliers?
There is no single complete database. VDMA member directories are the most reliable for machinery and plant engineering because membership implies a verified operating company. Wer liefert was (now part of Visable/Europages) has the broadest coverage. Industrystock and Kompass are useful for niche components. For legal verification of any listing, use the official Handelsregister at handelsregister.de.
Are free German supplier directories reliable?
Partially. Free directories are reliable for discovering that a company exists and roughly what it makes. They are unreliable for current contact details, capability claims and company status - listings are often years stale and are usually self-submitted. Treat any free directory as a lead source, then verify independently before you send an RFQ.
How do I get direct contact details for a German manufacturer?
Start with the company's own Impressum page, which German law requires to carry a real address and named managing directors. For the right person rather than the general inbox, trade fair exhibitor lists give named staff with roles, and VDMA member profiles often name a technical contact. A German-language enquiry to the Vertrieb (sales) address consistently outperforms an English enquiry to info@.
Should I pay for a German supplier database?
Paid databases are worth it when you need structured filtering - by capability, certification, size or region - across hundreds of candidates. They are not worth it for a single sourcing project with a clear product definition, where three hours of trade fair exhibitor lists and VDMA directories will find the same shortlist for free.
