Source hierarchy
We prioritise official statistical agencies, intergovernmental research and company releases, filings and product information. Source dates and reporting bases accompany material claims. Company descriptions remain attributed company statements, rather than independently validated performance.
Facts, forecasts and proposals
A historical production figure is different from guidance, a scenario or a development option. Forecast balances depend on their scope, horizon and stock assumptions. Company project dates remain conditional. Our proposed platform applications are identified as possibilities, not corporate commitments.
Working models
The four tools are deterministic JavaScript models. Formulas and units appear on each page. They use visitor-entered assumptions and contain no live price, technical database, AI inference, trading access or production connection. Default values are illustrative and are not calibrated to a buyer’s operation.
Review and correction
Sources were checked on 8 November 2026. This is not an automatically refreshed dataset. Latest dated announcements should take precedence over older static descriptions where they conflict. If an important source changes, record the revision and recheck dependent analysis.
Use of the content
Use this material to organise further research and professional questions. It does not establish a supplier recommendation, a commodity trade, regulatory compliance, an engineering design, a project valuation or investment advice. The ecosystem is selective, not a ranked procurement list.
