Buying NVIDIA H100 / H200 hardware from China: rules, risks and how to do it right
Buying H100-class hardware from a Chinese supplier is legitimate for most of the world, provided your paperwork is clean. Here is what the export rules say, why the stock exists at all, and the verification steps that separate a good deal from an expensive lesson.
What the US export rules restrict
The US Export Administration Regulations control shipments of advanced accelerators into China and a list of other restricted countries, that is the direction the headlines are about. Buying H100 or H200 hardware from a Chinese supplier for delivery to Germany, the United States or Kenya is a different transaction. The controlled event, if there was one, happened upstream in a supply chain we did not run; your import is an ordinary customs entry for computer hardware, filed by your broker or forwarder like any other.
Different does not mean paperwork-free. The buyer still needs a clean chain: a commercial invoice that names the real goods, correct HS classification, and a destination that is not sanctioned. We screen every order against denied-party lists, and we do not ship to sanctioned destinations. Russia, Belarus, Iran, North Korea, Syria and Cuba are off the table. If an order looks like a re-export to one of those, we decline it; the margin on one deal is not worth an enforcement case.
One caveat we owe you: none of this is legal advice. For edge cases, military or dual-use end users, planned re-exports, anything your own counsel hesitates over, bring in a trade lawyer before money moves, not after.
Why this stock exists in China at all
A reasonable buyer asks the question. It comes down to allocation cycles. Hyperscalers and large AI labs book accelerator allocations quarters ahead; projects get resized or cancelled after the hardware is committed, and the surplus flows into secondary channels. Add OEM overstock, system builders who ordered against forecasts that did not materialise, and you get a steady supply of PCIe H100 NVL cards and SXM modules moving through legitimate trading channels, and Shenzhen and Hangzhou are where those channels surface.
That liquidity is exactly why the market also attracts fraud, which is the honest half of the story and gets its own section.
Gray-market risks, and how to protect yourself
The failure modes are specific. Counterfeit or relabeled cards, a lesser GPU reflashed and reshelled to present as an H100, are the crudest. Subtler are genuine cards whose serials fail NVIDIA's verification because they were reported stolen or double-sold. And even a fully genuine card usually arrives with no warranty entitlement, because enterprise coverage was registered to the original purchaser. Every one of these has a defence, and we run all of them on every GPU order:
- Serial verification against vendor records before anything ships, a serial that does not check out kills the deal.
- Physical inspection: the card comes out of the shroud, and PCB, memory and markings are checked against reference units.
- Burn-in with GPU stress tests as part of our standard 24–72 hour cycle, sustained load, thermals and memory tests, not a five-minute demo.
- Photos and video of your exact units, serials visible, before the balance is due.
- Staged, escrow-friendly payment, you are never asked to pay in full against a promise.
The buying path, step by step
A GPU order runs the same rhythm as any of our builds, with the verification evidence doing the heavy lifting in the middle. You send the target configuration and we quote; a proforma invoice fixes the spec, Incoterm and bank details; a deposit starts sourcing and assembly. Then comes the part that matters: serial checks, inspection photos and burn-in results delivered to you before the balance is due. You pay the remainder only after reviewing the evidence, and the goods hand over EXW Hangzhou.
From that handover, freight is your side of the border. Every GPU server flies. If you have a forwarder, EXW is clean. If you do not, we help you appoint one who delivers DAP or DDP to any country in 1–2 weeks door to door and advances the import duties on an itemised invoice. To be explicit, because this trips people up: we do not deliver DDP ourselves, and a seller in China who claims to be your customs broker in Germany deserves your suspicion.
If H100 doesn't fit the budget
The H100 is not the answer to every workload, and at current pricing it should not be the default. H200 NVL is worth a hard look even against cheaper H100 stock, 141GB of faster HBM3e per card means fewer cards for a memory-bound job, which can invert the apparent price gap. For inference, an L40S serves most production models at a fraction of the cost, and the RTX PRO 6000 with 96GB of GDDR7 covers high-VRAM inference and workstation duty. And a well-tested second-hand A100 remains one of the best value-per-dollar training parts on the market, we burn those in and warranty them like everything else.

Frequently asked questions
Is it legal to buy an H100 from China?
For delivery to a non-sanctioned destination, yes, the US restrictions target shipments into China and certain other countries, not purchases from a Chinese seller to Germany, the US or Kenya. You still need proper paperwork: we prepare the export documents, and your forwarder or customs broker files the import entry. We screen every order against denied-party lists and refuse sanctioned destinations. For unusual end users or re-export plans, consult a trade lawyer, this is not legal advice.
How do I know the cards are genuine?
You see the evidence before your balance is due: serial numbers verified against vendor records, physical inspection of the actual cards, sustained GPU stress testing during burn-in, and photos and video of your exact units with serials visible. A card that fails any check does not ship.
Do H100s bought this way keep the NVIDIA warranty?
Usually not. Enterprise warranty entitlement is registered to the original purchaser and in most cases does not transfer through secondary channels. Your warranty is with the seller, in our case 1 year with cross-border advance-replacement RMA, which in practice is what keeps a production cluster running.
Which countries can you NOT ship to?
We do not ship to sanctioned destinations: Russia, Belarus, Iran, North Korea, Syria and Cuba. We also screen every buyer against denied-party lists and decline orders that look like re-exports to those destinations, whatever the nominal delivery address.
