China produces over 50% of the world's garments. For fashion brands looking to manufacture custom clothing, finding the right factory can mean the difference between a thriving product line and a costly failure. This guide walks you through every step of the vetting process — with practical tips you can use today.
1. Define Your Requirements Before You Search
Most brands waste time contacting the wrong factories because they haven't clarified their own needs. Answer these questions first:
- Product category: T-shirts, activewear, outerwear, or dresses? Different factories specialize.
- MOQ tolerance: Can you commit to 50 pcs, 500 pcs, or 5,000 pcs per style?
- Fabric requirements: Standard cotton, organic/GOTS-certified, or performance technical fabrics?
- Branding needs: Woven labels, hang tags, custom packaging, or poly bags only?
- Timeline: Do you need samples in 1 week or can you wait 3 weeks?
Pro tip: factories in Guangdong excel at fast fashion and activewear. Zhejiang factories often specialize in woven garments and outerwear. Knowing this narrows your search immediately.
2. Where to Find Clothing Manufacturers
Online Directories (Free)
- Alibaba.com — largest directory, but quality varies widely; filter for "Gold Supplier" + 3+ years
- Made-in-China.com — more factory-direct, less trading company noise
- Global Sources — strong for verified manufacturers, higher entry barrier
- 1688.com — Chinese domestic platform; cheaper but language barrier; use with an agent
Trade Shows (High Trust)
- Canton Fair (Guangzhou, April & October) — meet factories in person
- Intertextile Shanghai — fabric focus, but many manufacturers exhibit
- Global Sources Exhibitions (Hong Kong) — pre-vetted exhibitors
Referrals (Highest Conversion)
The best factories rarely advertise. Ask other brand owners in Facebook groups (Apparel Entrepreneurs, Fashion Brand Network) or LinkedIn. A warm introduction beats 100 cold emails.
3. The Factory Vetting Checklist
Before sending money or designs, verify these 8 criteria:
Business License & Registration
Request a copy of their business license. Cross-check the registered capital — legitimate factories typically have RMB 1M+.
Factory Audit Report
Ask for BSCI, SEDEX, or ISO 9001 audit reports. If they claim certification, verify the certificate number on the issuing body's website.
Production Capacity
How many units per month? How many production lines? A factory claiming 500K/month but showing 2 lines is suspicious.
Client References
Ask for 2-3 brand references. Contact them directly — not through the factory.
Sample Quality
Order a sample before committing to bulk. Evaluate stitching, fabric hand-feel, color accuracy, and construction.
Communication Speed
Do they reply within 24 hours? Slow pre-sales communication predicts slow production updates.
Payment Terms
Never pay 100% upfront. Standard terms: 30% deposit, 70% before shipment (or 70% against B/L copy).
Quality Control Process
Do they offer inline QC, pre-shipment inspection, and AQL sampling? Ask for a sample QC report.
4. Red Flags — Walk Away If You See These
- Refuses to provide a business license or factory address
- Quotes 50% below market rate (usually bait-and-switch or sub-contracting)
- Demands 100% payment before production
- Cannot produce a sample within 2 weeks
- No quality inspection process mentioned
- Only communicates via WhatsApp — no formal email or contract
5. Protecting Your Designs
Intellectual property theft is a real concern. Protect yourself:
- Sign an NDA before sharing tech packs or designs
- Watermark all sample images sent during negotiation
- Split production across 2+ factories for sensitive designs
- Register your trademark in China (CNIPA) before production
- Use unique fabric combinations that are hard to reverse-engineer
6. First Order Best Practices
Your first order sets the tone for the entire relationship:
Start Small
Order the minimum MOQ for your first run. Use it to evaluate quality, communication, and timeliness before scaling.
Document Everything
Keep records of all tech packs, sample approvals, email agreements, and QC reports. Disputes are resolved with documentation.
Inspect Before Shipping
Either hire a third-party inspection company (SGS, Intertek, BV) or request the factory's AQL inspection report with photos.
Build the Relationship
Chinese business culture values guanxi (relationship). Video calls, factory visits, and consistent communication build trust that translates to better service.
