About

lanthanides.io is an open price reference for rare earth elements and strategic metals, built and maintained by an independent researcher. Every price is tied to a specific seller, date, quantity, and verification status.

The site covers 31 elements across four categories: light rare earths, heavy rare earths, strategic metals, and semiconductor metals. Prices come from retail distributors, industrial wholesalers, and commodity benchmarks, normalised to USD per kilogram. Tools such as the price gauge are computed directly from those records.

Rare earth pricing is fragmented and paywalled. Commodity benchmarks sit behind expensive subscriptions, retail prices vary by orders of magnitude with form, purity, and quantity, and Chinese regulatory developments are poorly tracked in English-language sources.

Procurement analysts, researchers, and supply chain professionals need a single reference point that is open about where its numbers come from and what it does not know.

Reference prices are assembled from source-cited observations, and anyone who has seen a current price can add one. The quickest way is the Add a price form in the header: under a minute, no account. A maintainer checks every submission before it enters the open dataset.
