U.S. export controls bar those chips from China.\n\nLava spotted them through Nvidia's own DCGM Exporter, software that data center operators install to monitor server health and performance. It is meant for internal use, but it can often be reached from outside the data center network, and it does not always require a password. Lava cannot say where in China Telecom's network the chips are, and how they got there is unknown.\n\nNvidia did not deny the finding. A spokesperson said court cases have shown diversion of controlled products to be under one half of one percent, set against tens of millions of GPUs in service in approved countries. The spokesperson called smuggling a nonfactor.\n\nThat statistic deserves a closer look. It describes cases that reached court, which only counts chips someone caught. The B300 sighting came from an exposed monitoring tool, not from an enforcement action. Nvidia has said it is building a tool to locate its chips, but it has not shipped.\n\nThe pattern is not new. In 2025, Chinese companies reportedly smuggled $1 billion worth of Nvidia chips in three months, mostly B200s, while distributors were already preparing for the B300. The B300 offers 50% more memory and FP4 compute than the B200, per Nvidia. In August 2026, nine people were indicted in Taiwan over illegal B300 exports, and Supermicro said it had fired several employees after an internal smuggling investigation. One route ran through a Taiwanese server trading firm that held whitelisted buyer status.\n\nThat last detail undercuts the whitelist model. Rules that rely on approved buyers promising not to resell are only as strong as the least careful buyer. Thirty-two chips will not shift China's AI capacity on their own. They do show that the newest hardware reached China within roughly a year of shipping.","[\"nvidia\",\"export-controls\",\"china\",\"gpu-smuggling\"]","2026-10-23T12:26:23.000Z","2026-10-23T13:36:06.285Z","2026-10-23T13:36:08.686Z","published",null,[],"policy",[26,27,28,29],"nvidia","export-controls","china","gpu-smuggling",[31],{"name":32,"url":33},"Tom's Hardware","https:\u002F\u002Fwww.tomshardware.com\u002Ftech-industry\u002Fdata-centers\u002Fillegal-nvidia-blackwell-ultra-b300-gpus-found-inside-state-owned-china-telecoms-network-nvidia-says-chip-smuggling-a-drop-in-the-bucket-insists-smuggling-remains-a-nonfactor",0,{"sections":36},[37,42,47,51,56,61,66,71,76,81,86,91,96,101],{"name":38,"slug":39,"count":40,"latest_published_at":41},"AI","ai",7072,"2026-10-23T14:18:39.000Z",{"name":43,"slug":44,"count":45,"latest_published_at":46},"Security","security",1060,"2026-10-23T11:00:00.000Z",{"name":48,"slug":24,"count":49,"latest_published_at":50},"Policy",578,"2026-10-23T14:47:41.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Deals","deals",569,"2026-10-23T14:43:38.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Hardware","hardware",291,"2026-10-23T13:30:00.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Consumer Tech","consumer-tech",290,"2026-10-23T08:23:42.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Science","science",216,"2026-10-22T22:12:19.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Startups","startups",147,"2026-10-23T12:44:27.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Software","software",142,"2026-10-23T00:09:58.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Dev Tools","dev-tools",122,"2026-10-21T16:00:00.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"General","general",100,"2026-10-23T13:36:50.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"Gaming","gaming",88,"2026-10-22T22:25:33.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"Reviews","reviews",38,"2026-10-20T12:00:00.000Z",{"name":102,"slug":103,"count":104,"latest_published_at":105},"How-To","how-to",8,"2026-10-05T09:00:00.000Z"]
