Temu EU now rejecting battery certifications from non-approved labs – what’s the deal?

Got a rejection on a battery report upload: “The certification body is no longer accepted. Certificates from this institution will not be processed.”

Is this happening to others? Does Temu EU now only accept certifications from a specific list of approved labs?

Also a few questions for anyone who’s dealt with this:

Can one battery certificate cover multiple products? If they use the same battery, can I use the same report across different listings?

For products with built‑in batteries – do I need to disassemble the product and show the battery in the photos? Do they actually check that the battery info matches the certificate?

Appreciate any insights!

Can one battery certificate cover multiple products?
It depends. If the products use exactly the same battery (same brand, model, capacity, voltage), you can usually use one certificate for all of them. Color variations are fine. But if the battery capacity or size is different, you need separate certifications.
One trick: some labs will list multiple product models on the same certificate if they’re part of a series. Check with your lab – they might be able to issue one report covering several similar products.

This matches what our compliance guy told us too. Same battery spec is usually fine, but once the capacity changes even a bit, the lab wanted a separate file. The part about listing multiple models on one certificate is useful, I didnt know they’d do that for a series.

So if its just a color change on the same battery, Temu should accept the same cert?

Yes, color alone should not matter if the battery and model are identical. We had one listing in black and white on the same paperwork and it passed fine.

Built‑in batteries – do you need to disassemble?
Yes, you generally need to show the battery in your photos. The platform wants to see:

The battery label (clear photo showing model, capacity, voltage, CE mark)
The connection to the product (welding points, connectors, etc.)

Basically, they need proof that the battery in your product is exactly what’s listed in the certificate. If the certificate says one battery model and your photos show something different, they’ll reject it.

That makes sense, but it’s kind of annoying if the battery is fully enclosed. I had a similar issue with a power bank listing and they wanted teardown photos even though the product wasn’t meant to be opened. Did they actually accept close-up shots of the label through the casing, or was a full disassembly required in your case?

Cost estimate
I had to re‑test a product recently. Battery certification (UN38.3 + IEC 62133) from an approved lab cost me about €400–500. The full CE (EMC + LVD + RoHS) was another €600–700. It’s not cheap.
If you have multiple products that use the same battery, try to get the battery cert first and then see if the lab can issue product‑specific reports based on that. Some labs will do a “family model” approach to save costs.

That price range actually helps a lot. I was expecting the battery cert to be the expensive part, but the full CE package being another 600–700 explains why people keep trying to reuse reports. The family model idea is useful too — did the lab require the products to be basically identical, or just same battery and similar design?

The approved lab list is in the seller center under Compliance Center → Accredited Labs. It’s not a huge list – maybe 15‑20 labs globally. If your lab isn’t on there, you’ll have to re‑test.
One thing to watch: even if the lab was on the list before, they sometimes remove labs. So a certificate that worked six months ago might get rejected now. Always check before you assume.

That explains why people keep getting blindsided by rejections. I assumed once a lab was approved it stayed approved, but if they are pulling labs off the list then a cert can basically expire overnight. Do you know if Temu gives any warning when a lab gets removed, or do sellers just find out after the upload fails?

Maya24 Sep 12

Heads up: if they catch a mismatch, the penalties can be serious. I’ve seen sellers get fined for this – not just listing removal. One seller I know had a product that was selling well, they flagged a battery mismatch, and they got hit with a fine based on sales volume. Cost them thousands.
Make sure your product photos match your certificate exactly. If you’re using a battery from a different manufacturer than what’s on the certificate, get it updated before uploading.

That part about the fine based on sales volume is wild. I knew they could pull listings, but I didnt realize they were actually charging sellers like that. Makes the certificate/photo mismatch sound way riskier than people think. Do you know if they were able to fix it after updating the certificate, or was the penalty already locked in?
