Recently, the hydrochloric acid market in Jiangxi was stable in a narrow range. Steady utilization rate of local chlor-alkali plants contributed to sufficient HCL output. In addition to the self-use by those hydrochloric acid producers, some commodities are mainly supplied to local metallurgy, sewage treatment and other industries. The supply of hydrochloric acid in the province mainly comes from chlor-alkali enterprises with the market allocation mainly based on demand. The supply and marketing relationship was adjusted synchronously. In late May, with stable availability of the goods from factories, the market supply and demand changed little. As the supply of by-product hydrochloric acid was sufficient, the focus of market transaction was not high. The sales volume went up as the synthetic hydrochloric acid market went stable. Under such circumstance, the price remained at the previous level.
