❗ Important Reminder

Many top-ranked factories on B2B platforms do not publish an official public “top 10 ranking”. Rankings on third-party blogs are usually marketing content. It is highly recommended to shortlist 3–5 factories, send RFQ with your drawing, compare sample quality, unit price, MOQ, lead time and export terms.
