As a leading supplier for Seat Cover Leather Wholesale in the global auto aftermarket, WINIW specializes in bulk supply of high-performance, seat cover-specific leather—catering to B-end partners including seat cover manufacturers, 4S customization chains, fleet upgrade suppliers, and small-batch custom brands. Backed by 25+ years of automotive leather expertise, a 100,000+㎡ ISO 16949 & OEKO-TEX® dual-certified production base, and 8 automated tanning lines, we solve wholesale pain points: “high minimum orders, inconsistent leather adaptability, and slow bulk delivery.”
Our wholesale leather lineup is tailored to seat cover production with targeted advantages:
- Full-Grain Genuine Leather (Premium Grade): Selected top 8% of cowhide (retains natural grain for luxury texture), optimized for seat cover sewing—uniform thickness (0.9-1.1mm, no needle breakage during curved stitching) and high tear strength (≥35N/5cm). Passes 120,000+ friction tests (ISO 12947) to resist daily scratches, and features eco-friendly waterproof coating (water contact angle >115°) that wipes clean spills in 20 seconds. Ideal for high-end seat covers (luxury cars, vintage restorations), available in 50㎡+ bulk orders with color matching to Pantone/vehicle interiors.
- Nappa Soft Leather (Comfort Series): Softened via 15-stage tanning (touch hardness ≤32 Shore A) for seating comfort, with 35% elongation to fit bucket seats or lumbar support curves without cracking. Passes 800+ hours of UV aging tests (ASTM G154) to avoid fading, and is lightweight (300g/㎡) for easy cutting. Popular for family car seat covers, offered in 20+ classic colors with 30㎡+ minimum orders.
- Eco-Friendly PU Leather (Cost-Effective Bulk): Contains 35% recycled polyester (RCS-certified), low-VOC emissions (≤0.3mg/m³, EU REACH compliant), and fire-retardant properties (FMVSS 302). With 80,000+ friction tests and 5-year no-peeling guarantee, it’s perfect for mass-market seat covers (commercial fleets, budget cars). Available in 100㎡+ bulk rolls (1.4m width) to reduce cutting waste, with tiered discounts for 500㎡+ orders.
