Introduction
It should be noted that raw hides, bovine hides and calfskins are natural products. As a result,
companies trading in these products do not have control over all their properties. All links in the chain
should ensure that the best possible quality of the natural product skin is maintained. For this purpose,
controls should take place in the respective stages, the results of which are then brought to the
attention of the preceding stage, so that they can work on improving the quality there.
This document is intended to avoid disagreements between parties. It is the result of discussions with
representatives of agriculture, slaughterhouses, hides and skins processors and tanneries.
prEN 18199:2025 addresses essential requirements of traceability of hides and skins.
1 Scope
This document specifies the following for raw bovine hides and skins intended for use throughout the
leather manufacturing supply chain:
— Terms and definitions;
— Requirements for the presentation of raw hides and skins.
It is applicable to fresh and salted bovine hides and skins.
It outlines the opening cut and trim of hides and skins and the types of defects typically associated with
this raw material.
NOTE 1 Opening cut and trim vary from country to country.
It shows which parts of hides and skins can be used for leather production and which factors influence
the quality of hides and skins.
Furthermore, it gives recommendations on precautions to be taken for transport, preservation, loading
and unloading.
NOTE 2 For commercial agreements between the buyer and the supplier of hides and skins, operators use the
INTERNATIONAL CONTRACT No. 6 – HIDES and SKINS as drawn up by the International Council of Hides, Skins
and Leather Traders Associations (ICHSLTA) and the International Council of Tanners (ICT) [1].

preservation
treatment to protect hide and skin from rotting after flaying until further processing in the
tannery, by cooling or by salting
3.6.1
cooling
temperature reduction to significantly reduce bacterial activity and avoid preservation defects
3.6.2
fresh hides and skins
hides and skins, chilled to a temperature of less than 7 °C, but not below 0,3 °C
Note 1 to entry: The temperature of less than 7 °C, but not below 0,3 °C is to avoid salting.
Note 2 to entry: Temperature not below 0,3 °C prevents hides and skins, or parts of them, from freezing during the
chilling process.
