Denim is a town business in China
Global denim supply runs through three Pearl River Delta towns, and each has a different specialty. This guide explains Xintang, Dayong and Jun’an, when to buy from wash houses, and how denim OEM programs are priced.
Factory and stall contacts: Soudangkou directory.
The 3 denim towns
1. Xintang (Guangzhou) — the denim capital

The world’s densest denim cluster: weaving, cutting, sewing and washing within one town. Hundreds of factories produce for export brands; jeans OEM from ~300 pieces per style with custom washes.
2. Dayong (Zhongshan) — mid-to-premium jeans
Known for heavier fabrics and complex washes; the belt behind many European premium labels. Slightly higher MOQs, better finishing.
3. Jun’an (Foshan) — value denim
Cost-competitive basics and big-volume programs; strong for US discount retail programs.
4. The wash houses — where denim is actually “made”
Garment washing (stonewash, enzyme, distressed) is a separate craft here. Serious buyers pick the wash house themselves — it decides 70% of the final look.
5. Guangzhou fabric markets — the material layer
Zhongda Fabric Market stocks denim rolls from every weight; buying fabric directly unlocks smaller OEM runs.
6. 1688 & trade shows — shortlist online
Most Xintang factories list online; verify capacity by video call before sampling.
How denim OEM pricing works
- Fabric weight drives cost: 10oz vs 14oz can double fabric cost — specify in writing.
- Wash complexity is the second driver: hand-sanded details add per-piece labor; get wash cards approved before bulk.
- Sampling loop: expect 2–3 rounds (fit sample → wash sample → pre-production).
- Compliance: azo-free dyes are export-standard; request test reports for EU/US.
