Règles de négociation et conformité

Ces règles régissent le marché spot des GPU de datacenter : ce qui peut être listé, qui paie quoi, et comment les litiges sont tranchés.

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 considère que les H100, H200, B300, B200, A100, A800, H800, L40S et cartes grand public haut de gamme portent des classifications de contrôle des exportations américaines. Figurer sur une liste de contrôle n'est pas une interdiction de commerce : TKX est une place de marché mondiale et n'applique aucune restriction par défaut à ces modèles. La restriction s'attache au flux, pas au modèle — lorsqu'une transaction vise une juridiction sous restriction, TKX se limite aux prix et à la transmission des demandes : sans garantie, sans commission, et sans prétendre organiser l'approvisionnement. Licence d'exportation, douane et usage final incombent aux parties. Cette lecture des règles publiques n'est pas vérifiée par un avocat et ne constitue pas un avis juridique. TKX ne vérifie ni la destination finale ni l'usage final des transactions ; il appartient aux parties de s'assurer que leur opération respecte toutes les règles de contrôle des exportations applicables.

Traded on the market, but not the focus of this board — they sit last in the ordering and never enter the TKX-SPI index. This board is about mainstream data-center AI accelerators.
