Section II Standard Warehouse Receipt Delivery

The Measures for Standard Warehouse Receipt Management of Dalian Commodity Exchange shall apply to the generation, circulation and deregistration of the standard warehouse receipts, if not provided in the Detailed Rules.

A Member shall pay the notice of intent to deliver earnest money to the Exchange as per the standard of CNY thirty (30) per ton when it handles the notice of intent to deliver.

The owner which has fully completed the notice of intent to deliver shall, three (3) calendar days prior to loading the commodities in the warehouse, notify the designated delivery warehouse of the vehicle or vessel number, products, quantity, arrival time and other information, and the designated delivery warehouse shall reasonably arrange for receipt and loading-in of the commodities.

The designated delivery warehouse shall engage a quality inspection agency designated by the Exchange to carry out the quality inspection of the commodities to be loaded in the warehouse.

The owner shall notify, three (3) calendar days prior to the loading-in the warehouse, to the designated delivery warehouse the method of delivery, the quantity of delivery, the date of delivery, and whether to apply for the test of equilibrium moisture. The designated delivery warehouse shall notify, after its receipt of the owner's notice of loading-in the warehouse, to the designated quality inspection agency the aforesaid information which shall be clearly described in the quality inspection agreement. In addition, the quality inspection agreement shall provide for, among other things, the day and night operation fees, the method that the designated delivery warehouse notifies the designated quality inspection agency of the coke loaded in the warehouse, the quantity of inspection, the time of issuing the inspection report, and the liability arising out of or in connection with the incurred losses for any reason attributable to the designated quality inspection agency's failure to timely appear at the site. The inspection fees shall be borne by the owner and shall be forwarded by the designated delivery warehouse. If the owner does not apply for the test of equilibrium moisture, it shall be treated that the equilibrium moisture is >1%.

The sampling of the coke shall be carried out in the coke flows at the time of being loaded in and stacked in the warehouse.

The minimum quantity of the samplings shall be three thousand (3,000) tons, and any samplings less than three thousand (3,000) tons shall be deemed to be of three thousand (3,000) tons for the charge calculation purpose.

The receiving and consigning weights of coke shall be subject to the weighting by the designated delivery warehouse through measurement of wagon balance or rail weighbridge. The designated delivery warehouse shall, on the basis of the total moisture test result of the coke issued by the quality inspection agency designated by the Exchange and subject to the provisions of the Coke Delivery Quality Standard of Dalian Commodity Exchange ("DCE") (F/DCE J003-2024), calculate the weight which shall be the basis for issuing a warehouse receipt.

The quality inspection agency designated by the Exchange shall, after its completion of the quality inspection of the coke loaded in the warehouse, issue one (1) original and three (3) duplicate inspection reports; and the original shall be submitted to the designated delivery warehouse and two (2) of the duplicates shall be respectively submitted to the Exchange and the owner.

The designated delivery warehouse shall carry out, subject to the applicable provisions of the Exchange, inspection of the quality and other relevant materials and certificates of the coke which has been loaded in the warehouse.

The deregistration of the standard warehouse receipt shall be carried out against the standard warehouse receipts of the coke prior to the last trading day of each March.

When the coke is loaded out of the storage warehouse, the owner which holds the Notice to Load Out or load-out password shall contact the designated delivery warehouse for the loading-out matters three (3) calendar days prior to the actual pickup date, and shall pick up the commodities at the designated delivery warehouse within ten (10) working days (inclusive of the tenth working day) after the deregistration of the standard warehouse receipt.

Upon the coke being loaded out of the warehouse, the designated delivery warehouse shall issue to the owner the actual test result of total moisture tested by the designated delivery warehouse and produce the quality inspection report upon registration of the warehouse receipt.

The designated delivery warehouse shall calculate, on the basis of the actual test result of total moisture and the Coke Delivery Quality Standards of Dalian Commodity Exchange (F/DCE J003-2024), the weight to be loaded out of the warehouse and then have the sufficient weight loaded out.

The designated delivery warehouse may settle the quality premiums and discounts with the clients on the basis of the quality inspection report upon registration of the warehouse receipt. If the quality inspection report upon registration of the warehouse receipt does not stipulate the test result of equilibrium moisture, it shall be treated that the equilibrium moisture is >1%.

The two parties may also negotiate to draw and keep the samples and, in case of no objection from the buyer or seller to the quality of the coke within fifteen (15) calendar days after being loaded out of the warehouse, settle the quality premiums and discounts on the basis of the quality inspection report upon registration of the warehouse receipt, or otherwise on the basis of the sampling inspection results in case of any objection from the buyer and/or seller to the quality of the coke. In case there is any difference between the sampling inspection result and the inspection result upon registration of the warehouse receipt but within the error margin stipulated in the national standard and other relevant standards, the quality inspection report upon registration of the warehouse receipt shall prevail.

The owner who has a dispute with respect to the actual total moisture test result by the designated delivery warehouse shall entrust the designated quality inspection agencies to have the inspection carried out on site, and the inspection result shall be the weight measurement basis of being loaded out of the warehouse. The designated quality inspection agency shall be negotiated and determined by the owner and the designated delivery warehouse. If the negotiation fails, the Exchange shall designate the quality inspection agency. The inspection fee shall be borne by the owner.

In case the coke has not been loaded out of the warehouse, the owner shall firstly negotiate with the warehouse if there is any dispute about the quality inspection result of the coke. If the negotiation fails, the owner shall file a written application for re-inspection to the Exchange within ten (10) working days from the date of deregistration of the standard warehouse receipts. The application for re-inspection shall indicate the name of the warehouse, stack location, quantity, quality index and other information of the commodities to be re-inspected, leave the contact information and be affixed with the official seal of the owner. The owner shall be deemed to have no objection over quality of the loaded-out commodities if it does not file application in the prescribed manner within the prescribed period. The re-inspection shall be carried out by the designated quality inspection agency entrusted by the Exchange. The re-inspection fees shall be advanced by the owner.

The owner may choose either of the following two methods to have sampling and reserved sample carried out:

to continue the loading-out, and designate a quality inspection agency to have the sampling and reserved sample carried out in the coke flows; or

without loading-out, to designate a quality inspection agency to have the sampling carried out through shifting the stack or otherwise.

Both parties shall take the sampling inspection result as the basis for dispute settlement, and in case there is any difference between such sampling inspection result and the inspection result upon registration of the warehouse receipt but within the error margin stipulated in the national standard and other relevant standards, the sampling inspection result shall be deemed to be consistent with the inspection result presented by the designated delivery warehouse and inspection result upon registration of the warehouse receipt shall be used as the basis for dispute settlement.

Related fees and expenses (including, but not limited to, the inspection charges and the travel expenses) and the loss incurred thereby shall be borne by the owner in case the inspection result of the sample is consistent with the inspection result presented by the designated delivery warehouse, and otherwise, borne by the designated delivery warehouse.

When the coke is loaded out of the factory warehouse, the owner shall pick up the commodities at the factory warehouse within four (4) calendar days (inclusive of the fourth calendar day) following the deregistration day of the standard warehouse receipt (exclusive of the deregistration day). The factory warehouse shall commence consignment within four (4) calendar days (inclusive of the fourth calendar day) following the deregistration day of the standard warehouse receipt (exclusive of the deregistration day).

The factory warehouse shall consign the commodities in accordance with the loading-in quality standard under the contract, and shall provide the original quality inspection report issued by the factory to the owner, and the report shall be used as the basis of settlement of the quality premiums and discounts. If the quality inspection report does not stipulate the test result of equilibrium moisture, it shall be treated that the equilibrium moisture is >1%.

When the coke is loaded out of the factory warehouse, the factory warehouse shall carry out the sampling under the owner's supervision, and the samplings shall be sealed after being confirmed by both parties and shall be preserved for thirty (30) calendar days following the consignment day.

If the owner has any objection over the quality of the commodities to be loaded out of the factory warehouse, it shall firstly negotiate with the factory warehouse for settlement. If the negotiation fails, the owner shall, within ten (10) working days following the consignment day, file in writing an application for re-inspection. Such application shall indicate the name of the factory warehouse, stack location (if any), quantity, the quality index of the commodities to be re-inspected, leave the contact information and be affixed with the official seal of the owner. If no application is filed in the prescribed manner within the prescribed period, it will be deemed that the owner has no objection over the quality of the commodities that are being loaded out of the factory warehouse. The Exchange shall entrust a designated quality inspection agency to carry out the re-inspection over the reserved samples, and the sampling inspection result shall be the basis for any dispute settlement. In case there is any difference between such sampling inspection result and the inspection result presented by the factory warehouse but within the error margin stipulated in the national standard and other relevant standards, the sampling inspection result shall be deemed to be consistent with the inspection result presented by the factory warehouse and shall be used as the basis for dispute settlement. The re-inspection costs shall be advanced by the owner. If the inspection result of the sample is in conformity with the inspection result presented by the factory warehouse, the relevant fees (including but not limited to the inspection fees, traveling expenses) as well as any losses incurred thereby shall be borne by the owner; if not, relevant fees (including but not limited to the inspection fees, traveling expenses) as well as any losses incurred thereby shall be borne by the factory warehouse.

Where the factory warehouse consigns commodities to the owner at a speed no higher than the daily consignment speed but the owner fails to pick up the commodities due to its transportation capability or any other reason attributable to the owner, the owner shall pay to the factory warehouse the late fee as per the quantity of the commodities which shall be, but fail to be, picked up. The late fee is determined as follows:

from the starting date of goods pick-up (inclusive of the pick-up day), for each day, the amount of late fee on the then-current day shall be figured out by multiplying the quantity of the goods which shall be picked up but fail to be picked up on the then-current day by the corresponding amount of late fee; and

to the completion date of goods pick-up (exclusive of the pick-up day), the total amount of late fee which the owner shall pay to the factory warehouse shall be figured out on the basis of totaling the daily amount of late fee.

The standard amount of late fee shall be CNY 2/Ton*Day.

If the pick-up is carried out after expiry of the pick-up period (exclusive of the then-current day) and within nineteen (19) calendar days (inclusive of the then-current day) following the deregistration of the standard warehouse receipt (exclusive of the deregistration day), the owner shall pay the late fee to the factory warehouse, and the factory warehouse shall assume the liability related to the commodity quality, consignment time and consignment speed pursuant to the futures standards, unless all the futures commodities have been consigned.

The late fee shall be determined according to the following method:

from the date of expiration of pick-up period (inclusive of the expiration day), for each day, the amount of late fee on the then-current day shall be figured out by multiplying the quantity of the goods which shall be picked up but fail to be picked up on the then-current day by the corresponding amount of late fee; and

to the completion date of pick-up (exclusive of the pick-up day), the total amount of late fee which the owner shall pay to the factory warehouse shall be figured out on the basis of totaling the daily amount of late fee.

The standard amount of late fee shall be CNY 2/Ton*Day.

If the owner picks up the commodities at the factory warehouse after nineteen (19) calendar days (exclusive of the then-current day) following the date of deregistration of the standard warehouse receipt (exclusive of the deregistration day), the owner shall pay the late fee to the factory warehouse as calculated in the following formula, and the factory warehouse shall assume no liability related to the commodity quality, consignment time and consignment speed under the futures standards.

Amount of late fee = CNY 2/Ton*Day × Quantity of all the commodities × 19 Days

Where the factory warehouse fails to consign commodities according to the required daily consignment speed but timely completes the consignment of all the commodities, the factory warehouse shall compensate the owner.

Amount of compensation of the products = One-off delivery settlement price of the last delivery month of such commodity × Quantity of the commodities which shall be, but fail to be, consigned according to the required daily load out speed × 5%

Where the factory warehouse fails to timely complete the consignment of all the commodities, the factory warehouse shall, in addition to the compensation provided in Article 38 of the Detailed Rules, compensate the owner, the amount of such compensation for products = One-off delivery settlement price of the last delivery month of such commodity × Quantity of the commodities which shall be, but fail to be, consigned according to the total quantity of the commodities × 5%, the following procedures shall apply to such failure:

the Exchange shall supply to the owner the physical commodities of the same quality and quantity of other factory warehouses or locations and bear all the costs and expenses arising out of or in connection with the adjustment of the delivery site and the delayed consignment; or

where the Exchange fails to supply the above commodities, the Exchange shall refund to the owner the payment of the commodities and compensate the owner.

Amount of refunded payment of commodities and compensation = One-off delivery settlement price of the last delivery month of such commodity × Quantity of the commodities which shall be, but fail to be, consigned according to the total quantity of the commodities × 120%

In the event of any violation by the factory warehouse described in Article 38 or 39 of the Detailed Rules, the compensation shall firstly be paid to the owner by the factory warehouse. Where the factory warehouse fails to pay such compensation or the amount of compensation is insufficient, shall be handled by the Exchange subject to the applicable provisions of the Measures for Standard Warehouse Receipt Management of Dalian Commodity Exchange.

Chapter IV Supplementary Provisions

Any violation of the Detailed Rules shall be handled by the Exchange subject to the applicable provisions of the Measures against Rule Violations of Dalian Commodity Exchange and other rules.

The Exchange reserves the right to interpret the Detailed Rules.

The Detailed Rules shall come into force on July 1, 2019.

The document applies to metallurgical coke.

2. Cited rules and standards

The contents of the following documents constitute indispensable provisions of the Document through normative references within the text. For dated referenced documents, only the version corresponding to that date shall be applied to the Document; for undated referenced documents, the latest versions (including all the amendments) shall be applied to the Document.

GB/T 1997 Coke-sampling and Preparation of Samples

GB/T 2001 Coke-Determination of Proximate Analysis

3. Summary of the Method

After coke reaches saturated water absorption, it is dried at a temperature of (60±5) °C under standard atmospheric pressure for 4 hours. A specified mass of the dried coke sample is then weighed and dried to constant mass in an air stream at a temperature of (175±5) °C. The equilibrium moisture is calculated based on the mass loss of the sample after drying.

4. Experimental Instruments, Equipment, and Materials

4.1 Drying Oven

Equipped with automatic temperature control and blast device, capable of maintaining temperatures within the range of (60±5) °C and (175±5) °C, featuring gas inlet/outlet ports and sufficient ventilation volume, and capable of performing air exchange at least 5 times per hour

4.2 Industrial Balance

Sensitivity: 0.1 g

4.3 Shallow Tray

Made of heat-resistant and corrosion-resistant materials such as enamel, stainless steel, galvanized iron, or aluminum , with capacity capable of holding 500g of the sample, and the load per unit area not exceeding 1g/cm³

5. Experimental Procedures for Equilibrium Moisture

5.1 Collect a coke sample of no less than 5kg pursuant to the specifications in GB/T 1997. Immerse the entire coke in water and let it stand for 24 hours. Take out the coke and drain for 1 minute through a wire mesh basket.

5.2 Place the drained sample into a shallow tray and transfer to a drying oven that is pre-blasted and preheated to (60±5) °C. Dry the sample under air-blast condition for 4 hours.

5.3 Take out the dried coke sample and prepare a test sample of less than 13 mm pursuant to the specifications in GB/T 1997. Quickly weigh (500±10) g (accurate to 0.1 g) of the 13 mm sample in a pre-dried and weighed shallow tray and spread it evenly in the shallow tray.

5.4 Place the shallow tray containing the sample in a drying oven that has been pre-blasted and preheated to (175±5)°C. Dry the sample under air-blast condition for 1 hour.

5.5 Remove the tray, cool for 5 minutes, and weigh the sample accurate to 0.1 g.

5.6 Conduct inspection drying for 10 minutes each time until the difference in mass between two consecutive samples does not exceed 1g or the mass increases. Use the final mass for calculation. If there is a weight increase, the mass before the weight increase shall be used as the basis for calculation.

6. Calculation Results

6.1 Equilibrium moisture shall be calculated using formula (1):

·····················(1)

Where:

Mf means the equilibrium moisture of the coke, %;

m means the mass of the sample, in grams (g);

m1 means the mass of the sample after drying, in grams (g).

6.2 The test result shall be the arithmetic mean of the two test results.

6.3 Precision: The repeatability and reproducibility of equilibrium moisture determination shall not exceed the values specified in Table 1.

Table 1

Mass fraction of the equilibrium moisture /%（Mf）	moisture scope/%	repeatability /%	reproducibility /%
