I have a contractor onsite that is installing couplings from a manufacturer with no UL listing & only the EC stamp. I would like them to submit to the AHJ for approval he says there is no need.

Actually there is a need,

344.6 Listing Requirements.
RMC, factory elbows and couplings, and associated fittings shall be listed.

With that said, how are you determining that they are not listed?

There is no UL or accepted NRTL on the box & the couplings possess an EC stamp. Upon writing an email to the Mfg. Co., the reply was these items are "built to UL specs".

The EC is for "European commission" I believe the items are made in China.

I'd say you have good reason to reject them based on 344.6

I'd say he's got evidence to reject them but good reason hasn't been proven yet. Is the area c1d1? If not I'd like to hear some reasoning behind taking the time to pursue this trivial matter

No, good reason has been proven per the article mentioned, is a really necessary, not IMO but it is the code. If you have time why not submit a proposal to remove the listing requirement for a future code cycle.

Haha good one. Seeing as how that wouldn't financially benefit anyone on the cmp I think I'll save myself the effort and complain about it here

So, it will remain a code violation and enforceable.

BTW, I would prefer to buy American made anyways.

This seems like it would require incredible attention to detail, on an item as insignificant as a conduit coupling, relative to the total scope of the project. How likely is it that an inspector would notice the difference on a conduit coupling, that is still built to the same specs as most UL listed conduit couplings?

Plus, it very well could be that when you install a UL listed coupling, that the UL marking is out of view by pure luck, and major surgery to rework for showing the marking. If the inspector challenges you on this, even when you did install a UL listed fitting, what is your best course of action?

Show him the box they came in or an identical looking coupling with the mark visible?

As GoldDigger says, the listing information will be on the packaging or the manufacturer can provide it, this is covered in the UL White Book.

"Built to UL specs" does not mean UL listed It just means that the company thinks they meet. UL listing involves testing and manufacturing oversight (checking process and perhaps samples in an ongoing process) by UL.
 
there are other listing labs besides UL.

The codes doesn't say they have to be UL listed, just listed.

CE sounds more like they are built to some standard, other than being independently tested, but I'm not 100% sure CE wouldn't count as a listing.
