# indumás

> indumás is the public catalog of Argentine suppliers to oil and gas, mining, energy, agro and industry: verified manufacturers, machine shops, distributors and technical services in the 24 provinces, with their certifications. Free to search. The site is in Argentine Spanish.

## What it has

- Every company's page: what it does, addresses, certifications, categories, products and the organizations it belongs to. Its contacts (phones, WhatsApp, emails, website, social profiles) are on the page behind «Ver contacto», a click for a person, never in the HTML or the MCP server.
- Trust is labelled: "CUIT verificado" means indumás confirmed the company's tax ID; a certification is "Verificada en su registro" (checked against the certifier's registry), "Con certificado" (a certificate document was found) or "Declarada en su sitio" (only stated by the company).
- Organizations: chambers, clusters, industrial parks, unions and public bodies, and the events they run (exhibitions, fairs, business rounds, meetings), each with its participating companies by edition. Their contacts are behind «Ver contacto» on their page too.
- Paid placement is always labelled "Patrocinado" and never changes the order of results.
