From the buying desk

Concentrated 98% ships in T14-construction stainless-steel ISO tanks; T11 mild-steel tanks corrode within hours and destroy the cargo. Battery-grade specs are roughly 10x tighter on metals than technical-grade. See the sulfuric acid hub for full grade matrix and routing economics.

Import Card

Before you order sulfuric 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 Yunnan, Hunan, Inner Mongolia, Shandong. 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.
