What is GOST 28422-89?

The standard governs the leather itself, not the finished boot. It groups requirements into chemical properties (including moisture content, chromium oxide content and solvent-extractable substances), tensile strength, the stress at which the grain surface cracks, elongation at a given stress, and the finish's resistance to repeated flexing. Each is a physical test on the material, so leather either passes or it does not — there is no paperwork route around it.

This is why GOST decides who gets the order. A Russian or CIS military programme specifies the leather standard up front, and a factory that has not worked to it will often only discover during sampling that its leather cannot reach the required values. At that point the buyer has lost weeks and is back to sourcing.

It happened on a programme we now run. A Russian buyer took our quote, found a cheaper factory, and placed the sample development there — that factory could not meet the GOST 28422-89 leather-testing requirements or match the construction, and the buyer came back to us and asked us to build strictly to the spec. About a month of sampling later they placed their first order.

DOING manufactures military boots to GOST 28422-89 leather requirements, and will sample repeatedly against the standard until the material passes rather than proposing a substitute that "should be fine". If you are sourcing to a GOST specification, send us the standard and the spec — we will tell you honestly whether we can hit it.
