Section III FOT Delivery
Article 39 The maximum deliverable amount every day on each designated FOT delivery site shall be specified by the Exchange (detailed in the List of Delivery Warehouses and FOT Delivery Sites Designated for Blockboard of Dalian Commodity Exchange as Annex 2 attached hereto).
Article 40 The blockboard used for the FOT delivery by the seller shall be the blockboard provided by the designated FOT delivery site corresponding to the seller's delivery application. At the time of the FOT delivery, the seller may entrust the FOT delivery site on behalf of the seller, to perform the delivery obligation of blockboard and other related obligations. If the designated FOT delivery site fails to perform such obligations or perform such obligations in violation of relevant provisions, the seller shall bear the corresponding liabilities.
Article 41 The buyer shall confirm the basic material and paper impregnated thermosetting resins of the delivery goods within two (2) calendar days after the matching day (exclusive of the matching day). Each lot of the delivery goods shall have the same basic material and one or two kinds of paper impregnated thermosetting resins. Where the buyer chooses two kinds, the number of each kind shall be two hundred (200) or three hundred (300) sheets. The optional basic material and paper impregnated thermosetting resins shall be subject to the Exchange's announcement. If changes occur, the designated FOT delivery site shall notify the Exchange before the market close on the fifth (5) trading day of each April, August, December, and the Exchange shall announce such changes by the seventh (7) trading day of that month.

The seller shall provide the delivery goods based on the basic material and paper impregnated thermosetting resins the buyer chooses. In the case of failure to confirm the choice in time by the buyer, the seller may decide in its discretion the basic material and paper impregnated thermosetting resins of the delivery goods within the range announced by the Exchange.
Article 42 After confirming the choice of the basic material and paper impregnated thermosetting resins, the buyer shall negotiate with the seller on the handover day of goods (i.e., the FOT delivery date) in advance. The FOT delivery date shall not be later than the seventeenth (17) calendar day following the matching day (exclusive of the matching day), except for the case where the buyer and the seller agree to handle the handover of goods on their own according to Article 50 of this Detailed Rules.
Article 43 The seller shall load the goods to the buyer's transportation vehicle within the FOT delivery date.

If the goods have not started to be loaded to the buyer's transportation vehicles at 13:30 on the FOT delivery date for the reason of the buyer, the seller may store the goods at the designated FOT delivery site.

When the goods are loaded to the buyer's transportation vehicles or stored at the designated FOT delivery site for the reason of the buyer, it shall be deemed that the delivery is completed and the goods ownership is transferred. The handling fee incurred shall be borne by the seller; and all expenses (including but not limited to handling fee and demurrage charge) incurred consequently shall be borne by the buyer.
Article 44 The designated quality inspection agency shall arrive on site at the time required by the Exchange, record truthfully the arrival of the buyer's transportation vehicles and other relevant circumstances, and report them to the Exchange before the market close on the next trading day immediately following the FOT delivery date.

Upon pick-up thereof, the buyer must provide to the designated FOT delivery site the pick-up person's identity card, the certification issued by his or her employer recognized by the Exchange and the Notice to Load Out or load-out password.
Article 45 If the buyer fails to pick up the goods on time, the designated FOT delivery site shall not undertake any liability for changes in quality and quantity of the goods caused for reasons not attributable to its fault. The buyer shall pay the demurrage charge to the designated FOT delivery site based on the actual number of storage days (including the FOT delivery date and pickup date). The fee standard shall be separately published by the Exchange, unless otherwise agreed by the buyer and the designated FOT delivery site.
Article 46 If the buyer has no objection over the quality of the goods handed over, the buyer shall, prior to 11:30 a.m. on the fifteenth (15) trading day following the handover day, confirm the quality and quantity of the goods through the Member. If the buyer fails to do so, it shall be deemed that it has no objection to the quality and quantity of the goods. The Exchange shall refund the seller Member's delivery margin and make eighty percent (80%) of the payments for goods to the seller Member after the market close on the fifteenth (15) trading day following the handover day, and the remaining payments shall be fully settled after the seller Member provides the VAT special invoice.
Article 47 If the buyer has any objection over the quality of the goods handed over, it shall firstly negotiate with the seller. If the negotiation fails, where the buyer has objection over the appearance quality, specification and dimension, physical and chemical properties or formaldehyde emission, the designated quality inspection agency shall carry out the sampling inspection; where the buyer has objection over the kind of basic material, the designated quality inspection agency shall carry out the inspection to all disputed goods. The inspection result shall be the basis for any dispute settlement. The re-inspection costs shall be advanced by the buyer. If the re-inspection result is consistent with the result determined by the seller, the relevant fees (including but not limited to the inspection fees, traveling expenses, storage fees, stack shifting costs) and sampling loss incurred thereby shall be borne by the buyer. Otherwise, the relevant fees (including but not limited to the inspection fees, traveling expenses, storage fees, stack shifting costs) and sampling loss incurred thereby shall be borne by the seller.

If the re-inspection result is consistent with the delivery quality standards, the buyer shall pick up the goods normally, and the seller and the buyer will settle the differences of quality discounts and premiums according to re-inspection result. The Exchange shall refund the seller Member's delivery margin and make eighty percent (80%) of the payments for goods to the seller Member, and settle the remaining payments after the seller Member provides the VAT special invoice according to the following specified time:

in the case of the objection only involving the appearance quality, specification, dimension and the kind of basic material, the specified time shall be after the market close on the fifteenth (15) trading day following the handover day;

in the case of the objection only involving the physical and chemical properties, the specified time shall be after the market close on the twenty-second (22) trading day following the handover day;

in the case of the objection only involving the formaldehyde emission, the specified time shall be after the market close on the thirty-seventh (37) trading day following the handover day;

in the case of the objections involving several items of the quality, the longest period of time provided for the objection shall prevail.

In the case that re-inspection result is inconsistent with the delivery quality standards, the delivery shall be terminated and handled as the FOT delivery default.
Article 48 The seller Member shall provide the VAT special invoice corresponding to the actual delivery goods to the buyer Member within seven (7) trading days after the Exchange makes eighty percent (80%) of the goods payments.
Article 49 FOT delivery default shall mean that, within the stipulated time, the buyer fails to fully make the payments or the seller fails to fully deliver the blockboard conforming to the futures delivery quality standard at the stipulated place.

In case the buyer commits a delivery default, the Exchange shall notify the seller Member after settlement on the handover day, a punitive penalty shall be imposed by the Exchange against the buyer of twenty percent (20%) of the contract value of the defaulted portions calculated at the delivery settlement price on the matching day, which shall be paid to the seller; and the delivery shall terminate. Contract quantity of the buyer's delivery default shall be calculated as per the following formula:

Contract quantity of the buyer's delivery default (Lot) = [the payments which should have been paid (CNY) - the payments which have been paid (CNY)] ÷ [the delivery settlement price (CNY/Sheet) × (1-20%) + the premiums/discounts of designated FOT delivery sites (CNY/Sheet)] ÷ the trading unit (Sheet/Lot).

In case the seller commits a delivery default, the Exchange shall notify the buyer Member within the specified time according to Article 47 Paragraph 2 of the Detailed Rules, and a punitive penalty shall be imposed by the Exchange against the seller of twenty percent (20%) of the contract value of the default portions calculated at the delivery settlement price on the matching day, which shall be paid to the buyer; and the buyer's payments shall be released, and the delivery shall terminate.

Contract quantity for the portions insufficiently delivered by the seller (Lot) = [number of the goods which should have been delivered (Sheet) – number of the goods delivered (Sheet)] ÷ trading unit (Sheet/Lot).

The default quantity shall be calculated in "Lot" and rounded up to the nearest integer.
Article 50 The buyer and the seller may negotiate to handle the receipt and disbursement of the payments and handover of the goods for the FOT delivery by themselves, the specific processes shall be subject to the applicable provisions of the Detailed Rules and the Measures for Delivery Management of Dalian Commodity Exchange. If the buyer and the seller negotiate to handle the handover of the goods by themselves, but the receipt and disbursement of the payments are handled through the Exchange, the buyer Member shall supplement the full payments for goods before the market close on the handover day, and the Exchange shall transfer all the payments for goods and refund the delivery margins to the seller Member after the market close on the fifteenth (15) trading day following the handover day.
