Here are some starting places to look for chemical prices and business/industry information, with more resources on our chemical prices guide.
Some of these are databases where you can find prices of chemicals and materials (though not always bulk pricing) and larger full-text databases of trade and news publications where you may find articles about chemicals, companies, and industries. For the full-text searching, you may want to add words like price, costs, economic, and/or outlook to your search.
