According to the Commodity Market Analysis System of Shengyi Society, as of the 29th, the price of ethyl acetate was 5453.33 yuan/ton, a decrease of 16.67 yuan/ton or 0.30% compared to the price of 5470.00 yuan/ton on June 23rd. The supplier’s inventory level is still acceptable, downstream demand is average, market transactions are weak, and the quotation for ethyl acetate has been adjusted downward.

The utilization rate of domestic ethyl acetate production capacity has been reduced, and the inventory of enterprises is not under pressure, with strong quotations as the main factor. The enthusiasm of downstream market entry is not high, and the market trading atmosphere is weak. Some enterprises have poor shipments, coupled with the weak operation of acetic acid on the raw material side, the cost support is average, and the shipment of ethyl acetate in the market is hindered, causing the price center of ethyl acetate to shift downward.
Looking at the future, there is a supply-demand game in the ethyl acetate market, and manufacturers have a strong intention to ship. However, downstream purchasing is poor, and the pressure on ethyl ester enterprises to ship still exists. At the same time, the raw material market is bearish, and the cost support is insufficient. It is expected that the price of ethyl acetate will be weak in the later stage, and specific attention will be paid to changes in supplier equipment and downstream follow-up.

According to the Commodity Market Analysis System of Shengyi Society, the domestic aggregated MDI market showed weak performance in June and continued to decline. From June 1st to 30th, the domestic market price of aggregated MDI increased from 16333 yuan/ton to 15500 yuan/ton, with a monthly price drop of 5.1% and a year-on-year price drop of 12.66%.

In early June, Wanhua began maintenance on June 5th, and the Shanghai BASF and Huntsman units were restarting. The factory has a strong willingness to raise prices, but there is no significant increase in demand. Downstream entry into the market is cautious, and there is a strong wait-and-see atmosphere. The aggregated MDI market has begun to decline.
In mid to late June, the market supply remained stable, downstream demand was off-season, orders were low, and large factories in the north resumed operations, but the support for the market was limited. Without obvious positive guidance, the price of aggregated MDI continued to decline.
On the supply side, Shanghai Huntsman will restart production of 350000 tons in June. BASF’s 250000 ton plant in Shanghai will restart in June. Wanhua Fujian plant started shutdown maintenance on June 5th, with a duration of about 45 days. Large factories in the north will start reducing production in mid June.
On the cost side, the raw material pure benzene: In June, the pure benzene market fluctuated greatly with the trend of crude oil, and the price at the end of the month increased compared to the beginning of the month. On June 13th, tensions escalated in the Middle East, with oil prices reaching a two month high and pure benzene catching up significantly. On that day, the price of pure benzene rose by around 250-350 yuan/ton. On June 23rd, crude oil prices plummeted and pure benzene began to decline. On June 1st, the average price of pure benzene was 5735 yuan/ton, and on June 30th, the average price was 5984 yuan/ton, with a monthly increase of 4.05%.
On the demand side, the downstream is in a low season of demand, and the high price of aggregated MDI is not smooth. Although there is some support from the supply side, it is greatly affected by the constraints of the demand side.
In the future market forecast, the current MDI market supply side has a moderate willingness to raise prices, while the demand side maintains rigid procurement. Under the supply-demand game, it is expected that the short-term aggregated MDI market will operate in a narrow range.

According to the monitoring of the commodity market analysis system of Shengyi Society, the price of activated carbon at the beginning of the month was 12333 yuan/ton, and at the end of the month it was 12533/ton, with a price increase of 1.62%.

Domestic activated carbon manufacturers have seen some price increases this month, but most have remained stable. The ex factory price of coconut shell activated carbon for water purification is between 10000-13500 yuan/ton. The demand for coconut shell activated carbon in traditional fields such as water treatment and air purification continues to grow, and the market supply is tight. Industry insiders are mostly optimistic about the future market.
Internationally, 95% of coconut shell carbonization materials rely on imports. Southeast Asia, as the main source of coconut shells worldwide, will encounter multiple natural disasters in 2024: Thailand will experience a reduction in coconut production due to drought and pest infestations, and some production areas in Indonesia will be affected by abnormal rainfall at the end of the rainy season, resulting in a decrease in coconut shell collection efficiency and supporting price increases.
Prediction: The supply of activated carbon in the domestic and international markets is tight, and it is expected that the price of activated carbon will mainly fluctuate with a strong trend in the short term.

The equipment operating load of plasticizer enterprises increased slightly, and the demand support for phthalic anhydride increased. Supply has decreased and demand has rebounded, leading to an increase in phthalic anhydride prices.
Reduced supply of phthalic anhydride cost support
This week, the price of ortho benzene is temporarily stable. Sinopec’s ortho benzene quotation is 6900 yuan/ton, and the price is temporarily stable. The price of industrial naphthalene has fluctuated and risen, while the cost support of phthalic anhydride still exists. This week, the maintenance of phthalic anhydride equipment is still ongoing, and the operating rate of enterprises remains stable at a low level. The operating rate of the domestic phthalic anhydride industry has dropped to about 6.5%, and the supply of phthalic anhydride has decreased. The cost support supply has decreased, and the price increase of phthalic anhydride this week has provided significant support.
Demand side: DOP prices stop rising and fall back
