- Quality assurance — check if the factory supports third-party testing (SGS, Intertek) and certification for your market (EAC, etc.)
- Export experience — prefer factories with extensive export experience and knowledge of your target market's compliance requirements
- Communication — response speed and communication quality directly impact the partnership experience
China's underwear manufacturing advantages include a complete supply chain, abundant capacity, and high flexibility. Whether you're launching a new D2C brand or purchasing millions of units annually, you can find a matching factory partner.
