ThomasNet is a directory of suppliers. For suppliers that have agreed to post their catalogs within ThomasNet, this catalog collection can surface their prices, though many suppliers, especially for larger quantities ask you to contact them to request a quote.

This publicly-available directory of chemicals includes links out to vendor sites. Small quantity pricing usually is available on the vendor sites, though bulk quantities often require contacting the vendor for an estimate.

This trade magazine includes reports on individual chemicals, including pricing for a specified geographic region, at the back of every issue. The July 19th 2019 issue has many of their Chemical Profiles compiled in that special issue. Normally only a couple chemicals and regions are included per issue, so it sometimes takes some digging to find exactly the chemical you want. Searching for your chemical's name AND (price OR pricing) can help, but you may still need to convert currencies and estimate based on pricing outside the United States. Access via ProQuest includes pdfs of the pages, including graphs, while graphs are not included in the EBSCOhost version.

Annual reports on the mineral industry with estimates of bulk price for a variety of minerals. The entire report can be downloaded, or you can view just the report for a specific mineral. For some minerals, prices will be included in the table of information about them; for others, it will be in the text. Use the search feature (e.g. Ctrl-F) to find price in the document.

The commodity data search allows for graphing the change in the price of classes of chemicals relative to a base year. If you can only find a price from several years ago, this graph could be used to help you estimate what the current price would be.
