Main Standards for Leather

Leather is a key sector in Botswana and the BITC has identified as a potential export to the EU. In these pages you will learn the key issues on how to export leather to the EU.

At the international level, standards on leather are developed by the International Organisation for Standardisation (ISO) and the International Union of Leather Technologists and Chemists Societies (IULTCS). As the world’s leading developer of international standards, ISO standards specify the requirements for state-of-the-art products, services, processes, materials and systems, and for conformity assessment, managerial and organisational practice. They are designed to be implemented worldwide. The fact that many members of ISO are part of the governmental structure of their respective countries, while others relate uniquely to the private sector, allows ISO to act as a bridging organisation where consensus can be reached on solutions that meet both the requirements of business and the broader needs of society, especially those of consumers. The IULTCS not only provides a forum for the scientific debate on the leather industry worldwide, but also formulates relevant test methods to leather manufacture and leather usage.

The IULTCS test methods (IUC: IULTCS chemical test methods, IUF: IULTCS fastness test methods, and IUP: IULTCS physical test methods) are recognised by the ISO and indeed, many of them are adopted by the ISO as international standards.

Tips:

The European Committee for Standardisation (Comité Européen de Normalisation, CEN) establishes voluntary technical standards for the promotion of free trade, the safety of workers and consumers, interoperability of networks, environmental protection, exploitation of research and development programmes, and public procurement. European Standards (ENs) are produced by all interested parties through a transparent, open and consensus based process. They are a key component of the EU internal market, with a crucial role in facilitating trade both inside and outside Europe. They codify available best practices and are usually state-of-the-art.

CEN has adopted many of the IULTCS methods in parallel agreement with the ISO, which are mandatory in EU Member States. Consequently, the work of the IULTCS commissions has led to leather test methods that are now adopted as international, European and national standards.

Technical Standards

Leather products can be very different and have diverse purposes. Therefore different standards apply. Please visit the ISO and CEN/CENELEC website and search for the ISO or EU standards applying to your product:

Check also the Botswana Certification Bodies at BOBS as they can help you to get certified on ISO and EU standards.

Tips:

Check also the updated list of published ENs, as elaborated by the CEN and, when appropriate, also adopted by the ISO. They concern leather and its specificities, such as physical tests for the determination of certain values, the use of chemicals, or its resistance to abrasion:
