Step 1: Search for company names

This database lists certificates issued by coal mining companies, coal retailers and wholesalers, and companies that produced coke from coal.

Industries such as utilities, oil, and pipelines, and petroleum coke producers are considered "off-topic ".

Suggestions when searching

Do NOT use articles such as 'the,' 'of,' 'and,' or similar words in other languages. They are ignored.
Find results much faster and avoid spelling errors by entering word fragments. For example, enter "nor amer oil" instead of "North American Coal & Oil Company".
Word fragments are A-L-W-A-Y-S better than whole words.
The order of words does not matter.
Punctuation is NOT necessary.
