Reglas de negociación y cumplimiento
Estas reglas rigen el mercado spot de GPU de centro de datos: qué se puede publicar, quién paga qué y cómo se resuelven las disputas.
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.
| Tamaño de la operación | Tasa |
|---|---|
| <1000万 | 1.20% |
| 1000万–5000万 | 0.90% |
| ≥5000万 | 0.60% |

Export-controlled models
TKX considera que H100, H200, B300, B200, A100, A800, H800, L40S y las tarjetas de consumo de gama alta llevan clasificaciones de control de exportación de EE. UU. Estar en una lista de control no es una prohibición de comercio: TKX es un mercado global y no aplica restricciones por defecto a estos modelos. La restricción se adhiere al flujo, no al modelo: cuando una operación se dirige a una jurisdicción restringida, TKX solo publica precios y traslada consultas: sin garantía, sin comisión y sin afirmar que TKX organiza el suministro. La licencia de exportación, la aduana y el uso final corresponden a las partes. Esta lectura de reglas públicas no ha sido verificada por abogados y no constituye asesoramiento legal. TKX no verifica el destino final ni el uso final de ninguna operación; las partes deben asegurarse por sí mismas de que su transacción cumple todas las normas de control de exportaciones aplicables.
