About the notation of "leather"

Definition of "leather"

A new JIS standard (JIS 6541:2024) was established on March 21, 2024. As a result, the use of the terms "leather" and "leather" to name artificial materials other than artificial leather, synthetic leather, and recycled leather fiber composites will no longer comply with the JIS standard.

In order to prevent misunderstandings and confusion among consumers, SYRINX has decided to comply with JIS standards in the future. Specifically, we will no longer use terms such as "vegan leather" or "mushroom leather," and will gradually change them to terms such as "artificial leather" and "leather alternative material made from mushrooms," and will add explanations as necessary.

Although the JIS standard is a voluntary industry standard and has no legal force, there is a growing movement in Europe and other regions to limit the use of the terms "leather" to natural leather derived from animals (European unified standard EN15987, international standard ISO15115).
In Italy these regulations have been codified into law and any violations will be penalised.

As a brand that deals with both leather and leather alternatives, we understand the viewpoints of both parties, while at the same time aiming to contribute to creating a transparent environment that avoids misunderstandings among consumers.

Classification of "leather" and "leather substitutes"

Leather and leather alternatives are classified into the following three categories defined by the JIS standard, and further into category 4, which is not included in the JIS standard.

1. Leather

Animal skins that have been tanned to prevent decay.

2. Artificial leather/synthetic leather

A substitute for leather that uses synthetic resins such as polyurethane and polyvinyl chloride on the surface. This includes not only petroleum-based materials, but also those that have partly replaced with plant-based materials.

Examples: apple skin, cactus skin, leather substitutes made from mushrooms containing synthetic resins

3. Leather fiber regenerated composite (commonly known as recycled leather*)

A leather substitute material made from more than 50% crushed leather processed into sheets.

*The term " recycled leather " does not conform to JIS regulations.

4. Sustainable materials other than 1 to 3

A sustainable alternative to leather that does not contain synthetic resins and has a low environmental impact.

Examples: MYCL (Japanese mushroom-based leather alternative) , MuSkin (Italian mushroom-based leather alternative), Amadou (Romanian traditional mushroom-based leather alternative )
