No, all Alibaba suppliers do not offer Trade Assurance payments. Trade Assurance payments are provided by some suppliers only. So, make sure about the Chinese suppliers before writing money directly. Alibaba has set several parameters to ensure that only trusted, and reliable suppliers can participate in the Trade Assurance program. These parameters are based on the experience, reputation, product quality, quantity of the products they can sell, and the number of transactions they have had in the past.
