If you’re building a custom clothing brand, finding the right denim manufacturer in China can make or break your success. China remains the top sourcing destination in 2025—not just because of pricing, but because of its massive fabric supply chain, skilled workers, and scalable production capabilities.
But not every factory can handle custom designs, flexible MOQs, and fast turnarounds. That’s why we’ve put together this list of the 10 leading Chinese denim manufacturers trusted by serious B2B buyers. Whether you’re launching a new streetwear brand or expanding your collection, these suppliers are known for consistency, customization, and quality.
The 10 Denim Manufacturers in China
1. Valtin Apparel – Guangzhou, China
Valtin Apparel, based in Guangzhou, China, is a rising name in customized denim manufacturing, serving as a strategic production partner for fashion brands and private label businesses worldwide. While the company manufactures across a wide range of apparel categories, it has developed a strong reputation for its flexible, high-quality denim production services tailored to startups, boutique labels, and established fashion houses alike.
With five dedicated production lines, Valtin Apparel combines hands-on craftsmanship with modern garment-making technology to deliver consistent results—whether for small-batch streetwear labels or larger volume seasonal drops. The company offers complete OEM and private label services, including custom fits, sustainable fabric options, embroidery, digital printing, and advanced washing techniques such as enzyme washes, vintage fades, and eco-friendly ozone treatments.
Why Valtin Apparel Stands Out:
- Strong specialization in custom denim garments: jeans, jackets, and denim sets
- Flexible MOQ of 200 pcs across 4 sizes—ideal for emerging brands

2. ASPOP – Shandong, China
Founded in 2008, ASPOP (Shandong Haisebao Garment Group Co., Ltd.) is a vertically integrated denim apparel company with over 1,000 employees. While rooted in manufacturing, ASPOP’s strength lies in its trade + production model, which positions it as a specialized supplier for fashion-forward, small-batch denim collections. The company runs a design and marketing center in Los Angeles, allowing it to stay in tune with international trends and support clients with timely product development.
With 20 advanced digital denim production lines, ASPOP serves well-known brands such as NEXT (UK), GAP, BANANA REPUBLIC, A.E.O, and Lee. Their model is particularly appealing to global buyers looking for flexible order sizes, on-trend styling, and a reliable supply chain partner with a strong foothold in both China and international fashion markets.
Why ASPOP Stands Out:
- Over 1,000 employees with strong trade + manufacturing integration
- Specializes in small-batch, fashion-driven denim production
- Design and marketing center located in Los Angeles

With facilities for dyeing, weaving, finishing, wastewater treatment, and power generation, it operates one of the most complete denim production chains in Central China.
With over 625 employees and 480 looms, Discovery Denim combines scale with a deep commitment to sustainability. It holds a wide range of certifications, including ISO quality systems, OEKO-TEX, GRS, BCI, and REPREVE.

The company has long-term partnerships with iconic names such as Levi’s, Calvin Klein, GAP, American Eagle, Lee, Diesel, Tommy Hilfiger, Dickies, MUJI, NEXT, and C&A. It is deeply committed to sustainability, holding top-tier certifications like Oeko-Tex Standard 100, ZDHC, SA8000, and ISO14001.

While considered a younger player in the traditional textile space, Prosperity stands out for its bold and creative fabric innovations—like moisturizing denim, heat-generating denim, and pet-friendly denim.

Rather than functioning as a basic sewing facility, WILKINS positions itself as a creative production partner, helping fashion brands bring unique concepts to life with reliable craftsmanship.
With flexible MOQs starting at 500 pcs per style (and in some cases as low as 300 pcs), they’re ideal for new brands testing fresh ideas or running limited collections. Backed by an experienced workforce and detailed quality processes, WILKINS ensures each garment meets high standards—both in look and feel.
