Yes. Many startups successfully manufacture in China by choosing the right suppliers and preparing professional product specifications.
A typical project takes between 45 and 90 days, including product development, sampling, production, inspection, and shipping.
Most clothing manufacturers require minimum order quantities, although some factories offer lower MOQs for startups. For example, in sourcingyuan’s supply chain some factory only ask 50pcs to start up with customized design and private label.
