Contact MatQuo

We'd genuinely like to hear from you.

Get in touch to:

• Report a data or calculation error — spotted a figure that looks wrong, or a mislabelled source? Tell us and we'll check it.
• Suggest a material or calculator — a material, tool, country, tariff view or chart you'd like us to add.
• Ask about methodology or data sources — how a number is calculated, or where it comes from.
• Report a technical issue — something not working on the site.
• Make a privacy request — see the Privacy Policy for details.
• Report broken links or data-source issues — a dead link or a feed that looks off.

MatQuo is a public-data information and calculator project. It does not sell, source, broker, distribute, or arrange transactions in industrial materials, and does not provide procurement, sourcing, brokerage, or materials-trading services.

We're a small independent project, so we can't promise instant replies, but we read every message and aim to respond within a few business days.

For privacy-related requests, see our Privacy Policy. For the terms that govern use of the site, see our Terms of Use.
