Do You Have UL, CE or RoHS? An Honest Answer

No. We do not hold UL, CE, RoHS, FCC or NEMA certificates for the enclosure you are asking about.

We hold ISO 9000 for our quality system and CCC for the products where Chinese regulation requires it. Beyond that, the answer is no – and we would rather write that in the first email than lose an order quietly later.

A factory that answers “yes, we have CE” before it has seen your drawing has probably not understood the question. Here is why, and here is what a factory can legitimately give you instead.

Why the certificate usually belongs to the brand, not the factory

Compliance marks attach to a product as placed on the market, and the party placing it on the market is normally the brand or the importer – not the company that folded the sheet metal.

• CE marking is, for most directives, a manufacturer’s self-declaration. The manufacturer compiles a technical file, carries out a conformity assessment – often internal – and signs a Declaration of Conformity. Where a directive requires a Notified Body, that body assesses the product, but the declaration is still issued by the manufacturer. In an OEM arrangement, that manufacturer is you, not us.
• UL is a product safety certification issued by a Nationally Recognized Testing Laboratory. The applicant is normally the brand owner or importer, and the listing covers a specific product construction. A factory cannot lend you its listing for a product it did not submit.
• RoHS sits inside the CE framework as a substance restriction directive. The correct term is “RoHS compliant”, not “RoHS certified” – there is no certificate to hold. What exists is a declaration plus supporting test data on the materials used.
• NEMA ratings, such as NEMA 4 or 4X, describe an enclosure’s environmental performance. They are a rating claimed by the manufacturer against a standard, tested to prove it – again attached to the product, not to the workshop that made the box.

None of this is a technicality. If a supplier hands you a CE certificate with their own company name on it and your product is not in its scope, the document protects nobody.

What a factory can legitimately provide

This is the list worth asking for, because every item on it is real evidence rather than a logo:

Document	What it proves	Who issues it
Mill certificate / material test report	The steel or aluminium is the grade specified, with chemistry and mechanicals	The metal mill
Coating thickness and adhesion report	The plating or powder coat meets the specified thickness	Factory QC, or a third-party lab
Salt spray test report	The finish survived a stated number of hours under stated conditions	Third-party lab
First article inspection report	Critical dimensions measured against your drawing	Factory QC, countersigned by you if you wish
Dimensional and cosmetic inspection record	Batch-level conformance, with sample size stated	Factory QC
Third-party inspection report	An independent inspector checked the goods before shipment	SGS, BV, TUV, Intertek – your choice

Two notes on that table. First, a mill certificate is only as good as the traceability behind it – ask whether the heat number on the certificate matches the material in your parts. Second, third-party inspection is normally arranged and paid for by the buyer, and we support it: the inspector comes to the factory, we open the cartons, and we do not choose the inspector.

If you need UL or CE on the finished product

There is a path, and it starts before the design is finished rather than after the goods are made.

1. Design review against the standard. Creepage and clearance, earthing, insulation, flammability of plastics, temperature rise. The cheapest time to fix these is on a drawing.
2. Component selection. Power supplies, switches, terminals, wiring and fans usually need to be already certified for the target market. A certified box built from uncertified components does not pass.
3. Sample submission and testing. You submit to the laboratory for your market – UL Solutions, TUV, Intertek, SGS and others. Lead time is measured in weeks and cost in thousands, and neither is a factory decision.
4. Technical file and declaration. You assemble the file and sign the declaration, or your authorised representative does.

Our role in that sequence is step 1 and the manufacturing discipline behind step 3: building to the construction the laboratory approved, and not quietly substituting a component or a gauge afterwards. That last point is where OEM compliance actually fails – not at testing, but at the second production run.

Four red flags when a supplier says yes

• “CE certificate” as a JPEG in the first email. It is usually an EMC or LVD test report for one component, not a product certificate. Ask for the declaration and check its scope.
• The applicant name is not your brand. If the certificate names the supplier or an unrelated company, the listing does not cover your product.
• “RoHS certified”. There is no such certificate. Anyone using the phrase is either being loose or hoping you will not notice.
• “We can pass any test.” Nobody can promise a test result before testing. What a factory can promise is to build to the approved construction and to tell you when your design will not pass.

What we will not do

We will not print a CE or UL mark on a product that has not been certified for it, we will not lend you a certificate issued to another product, and we will not describe ISO 9000 as if it were a product safety approval. ISO 9000 says our process is controlled. It says nothing about whether your enclosure is safe for a 230 V mains feed, and any supplier who blurs those two is selling you a document rather than a product.

What this means practically

If your market needs CE, UL or FCC, plan for it as a programme cost with a timeline, and choose a factory that will build consistently to the approved design. If your product does not fall under those regimes – many industrial and furniture components do not – then the documentation that matters is dimensional, material and finish evidence, and that we can supply in full.

Our quality and certification page lists exactly what we hold and what we do not, without asterisks. The FAQ answers the same question in shorter form. And if you want to test us, send the question you were afraid to ask a supplier – we will answer it the same way we answered this one.
