When sourcing, it is critical to distinguish between Full-Grain Leather, Top-Grain Leather, and Split Leather. Full-grain leather is the highest quality, retaining the natural hide texture and offering the best durability and breathability. Top-grain leather is more common in high-end B2B transactions as it is sanded to remove imperfections, making it more uniform for mass production. Always request a Material Analysis Report to ensure the product is not 'bonded leather' or 'PU leather' if your requirement is for genuine animal hide.
