Aug. 21 | Nuno Castro | Yiwu, China.
Hi everyone,
My name is Nuno Castro. I’m Colombian-Portuguese and have spent most of my life here in China.
Today was another productive day working with my Brazilian client here in Yiwu.

He asked me to help identify factories for him to visit over the next few days, as well as arrange samples from different manufacturers.
The goal was to source samples from 10 different factories, including motorcycle exhausts and mufflers, cosmetic parts, and fiberglass needle mats.

I spent approximately five hours researching suppliers, gathering information, and verifying that the factories were actually producing the products our client was looking for.
This is an important part of the sourcing process because finding a supplier is only the first step — making sure you are dealing with the right factory can make a huge difference when it comes to quality, pricing, communication, and long-term cooperation.
After completing the factory verification, I spent another two hours communicating with the client, confirming the sample requirements, finalizing the orders, and processing the payments with the factories.

One thing I was reminded of today is that every client comes with a different level of knowledge, experience, and understanding of the sourcing process.
Some clients know exactly what they want, while others may need more guidance when it comes to choosing suppliers, understanding MOQs, evaluating factories, or deciding which products are worth testing.
That is where our role becomes especially important.

Every client has different needs and goals, and our responsibility is to do everything we can to help them achieve them.
