Arkei Leather SA from Argentina writes that the internationally recognised definition of leather as the International Standard Organisation (ISO) is: 𝐇𝐢𝐝𝐞 𝐨𝐫 𝐒𝐤𝐢𝐧 𝐰𝐢𝐭𝐡 𝐢𝐭𝐬 𝐨𝐫𝐢𝐠𝐢𝐧𝐚𝐥 𝐟𝐢𝐛𝐫𝐨𝐮𝐬 𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 𝐦𝐨𝐫𝐞 𝐨𝐫 𝐥𝐞𝐬𝐬 𝐢𝐧𝐭𝐚𝐜𝐭, 𝐭𝐚𝐧𝐧𝐞𝐝 𝐭𝐨 𝐛𝐞 𝐢𝐦𝐩𝐮𝐭𝐫𝐞𝐬𝐜𝐢𝐛𝐥𝐞, 𝐰𝐡𝐞𝐫𝐞 𝐭𝐡𝐞 𝐡𝐚𝐢𝐫 𝐨𝐫 𝐰𝐨𝐨𝐥 𝐦𝐚𝐲 𝐨𝐫 𝐦𝐚𝐲 𝐧𝐨𝐭 𝐡𝐚𝐯𝐞 𝐛𝐞𝐞𝐧 𝐫𝐞𝐦𝐨𝐯𝐞𝐝. To be clear to consumers about the origin and benefits of the materials used to make the product they are buying, the term Leather should only be used for materials that meet this definition an in some countries it is illegal to use the word ‘leather’ to describe anyting that does not.
