• Pricing: The benchmark price is based on tungsten concentrates containing 50% WO₃. For 40% < WO₃ ≤ 50%, the price decreases by RMB 100/mt in metal content for each 1% decrease in grade. For 50% < WO₃, the price increases by RMB 100/mt in metal content for each 1% increase in grade. If the grade does not meet the specified levels, the percentage grade will be rounded to two decimal places, and proportional pricing will be applied to the decimal portion. Other elements will not be settled.
(IX) This tungsten concentrate sale adopts a payment-before-delivery model. The buyer shall pay the purchase price to Kafang Branch before the goods are provided. Within five working days after the contract is signed, the buyer must pay 20% of the estimated total purchase value as a deposit; otherwise, it will be considered a forfeiture, and the bid bond will not be refunded. In principle, the value of tungsten concentrates supplied by Kafang Branch shall not exceed the amount already paid by the buyer. If the value of the supplied tungsten concentrates exceeds the amount paid by the buyer due to grade fluctuations, the buyer shall make up the shortfall within seven working days so that Kafang Branch can issue a VAT invoice to the buyer. If the buyer fails to purchase the tungsten concentrates according to the agreed quantity during the supply and marketing process, the deposit will not be refunded. The deposit will be automatically converted into payment for the goods during the buyer's final procurement.
(X) Weight determination and measurement will be conducted at Yunnan Tin Kafang Branch. The weight determination, measurement, and moisture testing of mine products shall be based on the results from Yunnan Tin Kafang Branch. Delivery is deemed complete once weight determination and measurement are finished and confirmed on-site by both parties. The sampling and preparation of mine product samples must be carried out under the witness and supervision of personnel from both parties. After processing, the samples will be divided into four portions: one each for Party A and Party B, one arbitration sample kept at Kafang Branch, and one sent by both parties to a mutually recognized, qualified testing institution in Gejiu for assay, which will serve as the basis for settlement. The assay costs shall be borne by the buyer. If there is a dispute over the detection data, both parties may submit to arbitration. The arbitration institution shall be a testing institution with testing qualifications that is different from the original sample testing institution and recognized by both parties. If the deviation between the arbitration result and the original result is within ±0.5% (including ±0.5%), settlement shall be based on the original data; if beyond this error range, settlement shall be based on the arbitration result.
(11) The buyer's estimated total purchase amount (the total purchase amount includes the deposit) must be fully transferred into the account of Yunnan Tin Co., Ltd. Kafang Branch within thirty working days after the contract is signed. Subsequently, the buyer shall pick up goods in batches from the warehouse of Yunnan Tin Co., Ltd.

If the buyer fails to pay in full as agreed or fails to handle the goods in a timely manner, and the contract performance period is exceeded, Yunnan Tin Co., Ltd.
