Frequently Asked Questions (FAQs)

How do I find reliable manufacturing companies in China?
You can find reliable manufacturers by searching on trusted platforms like Alibaba, Made-in-China, and Global Sources. Look for Gold Supplier or Verified badges, read customer reviews, and ask for references from previous clients to ensure credibility.

What should I check before choosing a Chinese factory?
Always verify the factory’s business license, certifications (like ISO), and production capabilities. Request samples to assess product quality and consider conducting a factory audit, either in person or via a third-party inspection agency.

Is it better to work with a manufacturer or a trading company?
Working directly with a manufacturer can offer better pricing and control over production, while a trading company may provide more product options and easier communication. Your choice depends on your specific needs and experience level.

How do I negotiate terms with a Chinese manufacturer?
Be clear about your product requirements, order quantities, and deadlines. Compare quotes from several suppliers and don’t be afraid to negotiate price, minimum order quantity, and payment terms. Build a relationship based on mutual trust and respect.

How can I protect my intellectual property when dealing with Chinese factories?
Sign a Non-Disclosure Agreement (NDA) and Non-Compete Agreement before sharing product details. Register your trademarks in China and limit the amount of sensitive information you share until trust is established. Consider using multiple suppliers for different components.
