All China Leather Exhibition focuses on the upstream choices that turn hides and skins into usable leather. Raw materials, wet blue, semi-finished and finished leather sit within a broader offer of tanning chemicals, machinery and production components. This is not simply a finished-shoe or leather-goods buying fair: a tannery selecting process inputs has different questions from a manufacturer comparing leather for footwear, furniture or accessories. The trade flow is also two-way, connecting Chinese suppliers and buyers with international tanneries and material businesses serving China. Buyers should define the processing stage, finish and intended use before comparing samples, while keeping material purchasing separate from equipment selection and any technical validation needed for the production process.
