I once received what I now call "6C" cable: Cheap Chinese Crap Counterfeit Communications Cable. Fake ETL, ROHS and UL stickers. ofc, I didnt notice any of this at first, my first tip off was the rabbit-pull boxes (2 of them) getting a horrible jam after about 25' of payout. So I open the boxes and find a 50 pack of "RJ-45" (8p8c) plugs and the cheapest, most garbage jack crimping tool I've ever seen, in each box, along with a datacom circuit tester and remote. :?
I check the order, nope, I didnt order those items.
I Google the cable mfg and part #s, and the results were ugly. They were also fake CMR, having failed a flame spread test. ALL of the markings were fake/fraudulent.
This was back in 2008 when scrap copper prices were pretty high. I took both boxes to a local (around the corner) scrapyard, and my assistant and I ate lunch with the proceeds. After lunch, I called the contractor for whom we were working and had a not-so friendly conversation with him, for ordering garbage cable and setting us back yet another day on that project.
*The datacom testers were actually pretty cool to have since, inexplicably, they had factory BNC connections in addition to the 8p8c. Were useful in testing continuity in siamese cable.
