My question assumed that MMC's middlings are used as thermal coal in China. There are a couple of data points here showing Chinese thermal coal price per ton above $30 USD.
Assuming that MMC had to truck the 0.4 mT of middlings they sold in the first six months of 2017 to the border, we still don't have a good explanation as to why their average selling price (ASP) was less than $15/ton.
While I appreciate that the company is more focused on transporting their primary HCC product, their financial results indicate that they still managed to sell a little bit of middlings.
Transportation costs are irrelevant to this discussion because I wasn't asking about the gross margin on middlings. I was asking why selling prices (the ratio of gross middlings revenues and unit volume sold) were so low.
