VI. Recent Spot Market Dynamics in China
Supply side: The overall operating rate of phthalic anhydride plants in China is low. Plants of companies such as Tongling Chemical and Panjin Reid have just resumed operations, and Changzhou Xinyang is operating at only about 50% capacity. Most manufacturers have low inventory levels, with some limiting sales and prioritizing their own use, leading to a tight supply of spot goods.
