Manufacturer rankings
Rankings are sorted by Factory Score — a transparency metric measuring publicly verifiable data completeness. We do not rank by any measure we cannot source, and we never claim a manufacturer is “the best”. Paid placements are labelled separately and do not affect these orders.

Why rankings here look different
Most “top manufacturer” lists are either paid placements or scraped from platform search results. This directory only ranks by data that can be checked: whether a company's own website describes manufacturing operations, whether it publishes export markets, whether its certifications can be traced to a source, and how recently the profile was verified.
A consequence is that our scores skew lower than a typical marketing site. That is intentional — it reflects what is actually verifiable, not what is claimed. Read the full methodology for the eight scoring components and their weights.
