From the buying desk

Concentrated HCl ships at 30 to 36% w/w in HDPE drums, IBCs, or rubber-lined ISO tanks. The fumes generate hydrogen chloride gas; ventilation at the receiver site is non-trivial. Common Chinese export sources are Shandong (chlor-alkali by-product) and Jiangsu.

Import Card

Before you order hydrochloric acid from China, see its register listing, the duty, anti dumping cases and a supplier check on one card, each with its source and date.

Typical Chinese supplier geography

Major Chinese capacity sits in Shandong, Jiangsu, Hebei. Coastal producers (Shandong, Jiangsu, Zhejiang) typically dominate export volume because of port access; inland producers (Inner Mongolia, Xinjiang, Shaanxi) compete on raw-material cost but add inland-rail or trucking cost to reach the coast.
