The delivery place of PVC is mainly limited to South China and Central China. Guangdong Province is the main warehouse in South China, Guangzhou and Foshan are the main warehouses, and Ningbo, Shanghai, Hangzhou, Changzhou and Suzhou are the main delivery warehouses. Guangdong accounts for about 27% of the total consumption, and these four provinces and cities account for about 50% of the total consumption. The price of the whole Guangdong Plastic Exchange is very recognized by everyone in the spot market, and the plastic index is very wide. The price in Guangdong is representative. We also use GS model (econometric statistics) to analyze and find that the prices in Guangdong and South China actually dominate the national price and have a leading influence on the markets in East China and North China.

The standard PVC product is SG5-type first-class product, and its quality standard conforms to the national standard "Suspension Universal PVC Resin (GB/T 576 1-2006)". Superior products are allowed to be delivered as substitutes, and there is no grade premium between superior products and first-class products. SG5 is the most common type of PVC, and SG5 is the national standard, which is mainly applicable to calcium carbide process. 50% of the domestic market uses calcium carbide machines, but in fact, we don't distinguish between ethylene materials and calcium carbide machines in the whole process, and ethylene materials can still be delivered. It does not distinguish between ethylene and calcium carbide. If it is imported and there is no recommended brand, the quality can fully meet our delivery requirements. It also needs to be inspected by a quality inspection agency of CCIC and SCS, and it can only be delivered after passing the inspection.
