According to the Commodity Market Analysis System of Shengyi Society, the focus of the domestic PTA spot market has shifted downwards in June. As of June 6th, the average price of PTA in the East China region was 4903 yuan/ton, a decrease of 1.26% from the beginning of the month.
The geopolitical dispute continues, and OPEC+eight major oil producing countries have agreed to increase their daily oil production by 411000 barrels in July, with the increase not exceeding expectations and crude oil showing a strong trend. As of June 5th, the settlement price of the July WTI crude oil futures contract in the United States was $63.37 per barrel, and the settlement price of the August Brent crude oil futures contract was $65.34 per barrel.
However, the supply and demand margin of PTA itself has narrowed, and maintenance facilities have been restarted one after another. The utilization rate of PTA production capacity has exceeded 82%, and domestic supply continues to increase.
The negative impact of downstream polyester production reduction is gradually being realized, and the demand side is showing a sluggish performance. Affected by the off-season in the terminal textile market, factories reduced production and went on holiday during the Dragon Boat Festival, and the resumption of work after the holiday fell short of expectations, resulting in a continuous decline in weaving load. At present, the level of terminal orders is average, and consumption growth is slow.
Business analysts believe that there are many external instability factors, the international oil price trend lacks sustainability, PX spot prices are tight, and it is expected to remain strong in the short term, with cost support still acceptable. As the off-season deepens and domestic and foreign trade orders perform poorly, there is an expectation of weakened supply and demand, resulting in a continued weakness in PTA prices in the short term.

However, the demand for phthalic anhydride did not grow well, and phthalic anhydride enterprises resumed production, with the operating rate of phthalic anhydride enterprises increasing to about 70%. Downstream demand for plasticizers rebounded, and the increase in supply and demand did not meet expectations, resulting in a continuous decline in phthalic anhydride prices.
Supply side: resumption of work and increase in supply
The phthalic anhydride plant has resumed operation, and the capacity utilization rate of the domestic phthalic anhydride industry has increased to about 70%. The capacity utilization rate of the naphthalene phthalic anhydride industry has remained stable; The utilization rate of production capacity in the domestic phthalic anhydride industry has been improved, and the supply of phthalic anhydride has increased.
Demand side: DOP market hits bottom and rebounds
According to the Commodity Market Analysis System of Shengyi Society, as of May 30th, the DOP price was 8250.83 yuan/ton, a decrease followed by an increase of 1.27% compared to the DOP price of 8147.50 yuan/ton on May 1st; Compared with the DOP price of 7850 yuan/ton on May 11th, it rebounded and rose by 5.11%. In early May, DOP prices continued the downward trend of April and fluctuated downwards. Starting from mid May, with the easing of tariffs and the expected increase in demand for plasticizers, the price of plasticizers hit the bottom and rebounded. In addition, the price of raw material isooctanol first fell and then rose, the price of phthalic anhydride fluctuated and fell, the cost of plasticizers first fell and then rose, and the price of plasticizers hit the bottom and rebounded.
Future forecast
According to the data analyst of Shengyi Society’s phthalic anhydride products, on the supply side, phthalic anhydride manufacturers have increased their production, resulting in an increase in phthalic anhydride supply; In terms of demand, during the economic and trade negotiations between China and the United States, it is expected that the plasticizer market will rebound, and the demand for phthalic anhydride will increase. However, the demand recovery is not as expected, and the support for phthalic anhydride demand is insufficient. In the future, with strong supply and weak demand, it is expected that the price of phthalic anhydride will remain weak and stabilize.

The price of isooctanol first fell and then rose in May
According to the Commodity Market Analysis System of Shengyi Society, as of May 29th, the price of isooctanol was 7533.33 yuan/ton, a decrease followed by an increase of 0.67% compared to the price of 7483.33 yuan/ton on May 1st; Compared to May 12th, the price of isooctanol fluctuated and rose by 4.87% to 7183.33 yuan/ton.

According to the monitoring of the commodity market analysis system of Shengyi Society, the 1 # tin ingot market in East China fell and rose this week (5.26-5.30), with an average market price of 264520 yuan/ton at the beginning of the week and 251610 yuan/ton at the end of the week, a decrease of 4.88%.
On the supply side, the overall supply situation of major tin ore supply areas such as Yunnan is becoming tight. As a result, some smelting enterprises may take measures to suspend production and maintenance in the future to cope with the shortage of raw materials. In terms of the market, there has been a particularly strong reaction to rumors that resuming production in the Wa region requires payment of relevant fees. At present, only a few enterprises have completed the payment procedures for mining certificates, and most enterprises are still adopting a wait-and-see attitude. Most top mining traders have not taken any action. In addition, the current review measures at the China Myanmar border are relatively strict, and the entry procedures for large equipment and related mining personnel are cumbersome and complex, which further affects the resumption of production in the Wa region and prevents it from meeting market expectations.
On the demand side, the trading activity in the spot market has significantly increased recently. After the tin price experienced a sharp decline, some companies seized the opportunity to launch procurement actions. With the further decline in prices, the purchasing willingness of downstream and end enterprises has significantly increased, and they have made essential purchases according to actual needs and appropriately replenished inventory.
comprehensive analysis
In the downstream application field of tin, the market performance of tinplate and tin chemical industry is relatively average, while the increase in demand mainly comes from the largest proportion of tin solder materials. However, there are still hidden concerns on the demand side, that is, in the context of global trade conflicts, the global economic growth rate is facing the risk of decline, which brings great uncertainty to the demand for tin. Although the resumption of production in the mining sector and trade conflicts between major countries have had a negative impact on tin prices, the strong performance of the current actual demand side and the shortage of tin ore supply can still provide some support for tin prices.
