DC-GPU Trading Rules & Compliance

These rules govern the DC-GPU spot market — what may be listed, who pays what, and how disputes are settled.

Spot only

Every listing must be physical stock available for inspection or shipment within 7 days. Futures, in-transit goods, pre-orders and paper positions are not accepted.

TKX does not hold your money

TKX is a broker, not a payment institution. Funds move directly between the buyer's and seller's corporate accounts or through their banks. TKX verifies payment evidence, inspection records and SN manifests, and rules on disputes. Any page or person claiming TKX will custody your payment is not TKX.

Human review, every listing

Listings, requests and quotes are reviewed by a person before publication. False stock, empty quotes and manipulative bids cost the account its posting rights.

SN is the record of title

Serial numbers are the sole hardware identity of record. Buyers must record an unbroken unboxing or on-site inspection video. Where delivered SNs do not match the manifest, arbitration favours the buyer.

Inspection window

Buyers have 72 hours from arrival or on-site handover to accept or raise a dispute. Silence past the window counts as acceptance.

Evidence ranking in arbitration

SN match, then unboxing or on-site video, then the written listing or quote, then platform chat records, then benchmark screenshots.

Fee schedule

Paid by the buyer, on top of the goods payment: below CNY 10m — 1.20%; CNY 10m to 50m — 0.90%; CNY 50m and above — 0.60%. Long-term contracted buyers may be configured down to a 0.40% floor. The fee covers source verification, evidence retention and dispute arbitration.

Export-controlled models

TKX reads H100, H200, B300, B200, A100, A800, H800, L40S and high-end consumer cards as carrying US export-control classifications. Being on a control list is not a trading ban: TKX is a global marketplace and applies no default restriction to these models. The restriction attaches to the flow, not the model — where a transaction is destined for a restricted jurisdiction, TKX publishes price information and forwards inquiries only: no escrow, no brokerage fee, and no representation that TKX organises supply. Export licensing, customs and end-use compliance rest with the transacting parties. This reading of public rules is unverified by counsel and is not legal advice. TKX does not verify the ultimate destination or end use of any transaction; parties must satisfy themselves that their trade complies with all applicable export-control rules.
