Metals & critical minerals knowledge
Practical guidance for buyers, sellers and intermediaries defining technical, commercial and responsible-sourcing requirements.
Practical guidance for buyers and suppliers defining metals and critical-mineral transactions.
Define the material before discussing a counterparty
Metals and critical minerals cannot be assessed reliably from a broad commodity name alone. Element, compound, concentrate or finished form, grade, purity, particle size, assay basis and processing stage can determine whether a material is technically suitable and commercially comparable.
The articles below address the information buyers, sellers and authorised representatives should clarify before approaching the market. They also explain why origin, processing history, end use, packaging, inspection and traceability may be central to a proposed transaction.

A metals buyer should identify the legal entity, exact material, acceptable technical range, quantity, destination, intended application where relevant and required delivery period. A supplier should state its relationship to the material, origin, processing location, current location, realistic volume and available analysis.
REVDICO acts as an independent commodity broker. The presence of a material on the website is not evidence of stock or allocation; actual availability and suitability must be established for the specific opportunity.

Traceability, authority and lawful trade
Material origin, extraction and processing locations, beneficial ownership, seller authority, destination and end use can affect both commercial acceptance and legal review. A country appearing in a regional section does not clear an individual transaction.
Assay reports, certificates and warehouse records should relate to the material being discussed and should be verified at an appropriate stage. REVDICO does not support concealed origin, misleading analysis, disguised ownership or circumvention of applicable restrictions.
Information needed for a metals enquiry
Identify the metal, element, compound or concentrate precisely. State grade, purity, physical form, assay or technical specification, quantity, origin or acceptable origin, current location, destination, delivery basis and timing. If end use affects technical suitability or trade controls, provide the relevant context.
Suppliers should distinguish typical analysis from lot-specific results and clarify whether they are producers, owners, authorised sellers or representatives. Buyers should describe acceptable tolerances, inspection expectations and receiving capability so that materially different products are not compared as though they were interchangeable.
Move from technical definition to commercial assessment
Use the material pages to check which technical details matter, and the regional pages to consider origin, processing, logistics and documentation. Once grade, form, volume and geography are clear, the metals enquiry form provides the quickest route to an initial commercial review.
Present a specific metals requirement
Send the material, grade or purity, form, quantity, origin, destination, timing and available technical documents. REVDICO can then determine whether the proposition is sufficiently defined for further discussion.
