3 Requirements

3.1 White sugar for futures trading is divided into Grade I and Grade II * * according to the technical requirements.

3.2 Sensory index:

3.2.1 The grain size should be uniform and not less than 81% in the following range:

-coarse grain: 1.81～2.51mm;

—— large grain: 1.63～1.61mm;

—— medium particle: 1.45～1.25mm;

-small grain: 1.28～1.81mm

-fine particle: 1.14 ~ 1.45 mm.

3.2.2 The crystal grain or its aqueous solution tastes sweet and has no peculiar smell.

3.2.3 Dry, loose, white and shiny, with no obvious black spots.

3.3 The physical and chemical indexes of white granulated sugar for futures trading are shown in Table 1

Table 1. The project indexes are sugar content of primary and secondary cane,% ≥ 99.6 99.5 reducing sugar,% ≤ 1.11 1.15 conductance ash,% ≤ 1.11 1.13 loss on drying and% ≤ 1.17 1.11 color value. IU ≤ 151 241 turbidity, MAU ≤ 161 221 insoluble in water impurities, mg/kg≤ 41 61 3.4 Hygienic requirements

The indicators of sulfur dioxide, arsenic, lead, copper, total number of colonies, coliforms, pathogenic bacteria and mites in white sugar shall be implemented according to GB13114, and the yeast (CFU/g) shall be ≤ 25.

4 inspection methods

4.1 sensory items

inspection shall be carried out according to GB317.

4.2 physical and chemical items

inspection shall be carried out in accordance with the provisions of GB317. The turbidity of the white sugar sample = X1-X2, where x1 is the attenuation index of the solution before filtration, and MAU and x2 are the color index of the sugar solution after microporous membrane filtration, MAU. The unit of turbidity of white sugar sample is milliattenuation unit (MAU), and the calculation result is an integer. The difference between the two measurements should not exceed 11% of its average value.

4.3 sulfur dioxide, arsenic, lead and copper

shall be inspected according to the provisions of GB/T5119.55.

4.4 the total number of colonies, coliforms, pathogenic bacteria, yeasts and molds

are tested according to GB/T4789.1, GB/T4789.2, GB/T4789.3, GB/T4789.4, GB/T4789.5, GB/T4789.11 and GB/t.

4.5 mites

The inspection shall be conducted according to the provisions of GB317.

5 inspection rules

The delivery inspection of white sugar futures shall be carried out according to GB317 delivery inspection, and all the items are required by physical and chemical indicators.

6 signs, labels, packaging, storage and transportation

6.1 signs, labels

The label of white sugar for futures delivery shall comply with the provisions of GB7718 and shall contain the following contents:

a) product name;

b) level;

c) net content (kg or g);

d) the legally registered name and address of the packaging or distribution unit;

e) product standard number;

f) production date.

6.2 packaging

6.2.1 packaging bag

The white sugar for futures delivery must be packaged in packaging bags that meet the hygiene standards, and there should be solid outer packaging bags (such as woven bags).

6.2.2 packaging measurement

the white sugar for futures delivery shall be packaged in a single piece of 51kg, and the negative deviation of the net content of the single piece shall not exceed 111g, and the average deviation of the batch shall be greater than or equal to zero.

6.3 for each batch of white sugar delivered in the future, the manufacturer shall attach a product certificate and a description of transportation and storage conditions.

6.4 storage and transportation

when the white sugar for futures delivery is put into storage, the sugar transport tools must be clean and dry, and it is strictly forbidden to transport white sugar mixed with harmful, toxic, odorous and other easily polluted items. When transported by ship, there should be a cushion under the sugar pile to prevent it from getting wet. Trading place

The details of the white sugar futures contract are basically as follows: the contract unit is 1,111 tons, the on-site margin is 6%, the price increase or decrease is limited to 4% of the settlement price of the previous day, and the standard product for delivery is first-class white sugar (including cane sugar and beet sugar).

The price of white sugar fluctuates greatly, and the trading volume is large. It is a relatively successful futures contract in the international market. After a long period of research and demonstration, Zhengshang Institute believes that white sugar futures trading should be active. In addition, in the setting of delivery warehouses, we are also going to set up a number of delivery warehouses in the south to facilitate production and marketing enterprises and strengthen circulation. As for the impact of sugar futures on wheat futures, I think we should look at it from two aspects: first, wheat futures need a period of time to cultivate, especially as a large variety, and whether it can attract a large amount of hot money in the short term cannot be the only measure. Secondly, if sugar futures are successfully traded, it will definitely weaken the position of wheat futures contracts in the short term, but in the long run, they are not the same variety after all, and it is not impossible for them to develop together.
