NEW YORK (TheStreet) -- Shares of Cliffs Natural Resources (CLF - Get Report) were falling 11.9% to $7.02 Thursday following reports that China will reinstate import tariffs on coal imports.

The Chinese Finance Ministry will impose a tariff of up to 6% on coal imports, including 3% on anthracite and coking coal, on Oct. 15, according to Bloomberg. The country previously suspended similar tariffs in 2007 and reintroduced a tax on brown coal in August 2013.

The tariffs are reportedly aimed at helping Chinese miners, 70% of which are unprofitable, according to Bloomberg.

TheStreet Ratings team rates CLIFFS NATURAL RESOURCES INC as a Sell with a ratings score of D+. TheStreet Ratings Team has this to say about their recommendation:

"We rate CLIFFS NATURAL RESOURCES INC (CLF) a SELL. This is driven by several weaknesses, which we believe should have a greater impact than any strengths, and could make it more difficult for investors to achieve positive results compared to most of the stocks we cover. The company's weaknesses can be seen in multiple areas, such as its generally disappointing historical performance in the stock itself, unimpressive growth in net income, poor profit margins, weak operating cash flow and generally high debt management risk."

Highlights from the analysis by TheStreet Ratings Team goes as follows:

  • Despite any intermediate fluctuations, we have only bad news to report on this stock's performance over the last year: it has tumbled by 53.38%, worse than the S&P 500's performance. Consistent with the plunge in the stock price, the company's earnings per share are down 101.21% compared to the year-earlier quarter. Despite the heavy decline in its share price, this stock is still more expensive (when compared to its current earnings) than most other companies in its industry.
  • The company, on the basis of change in net income from the same quarter one year ago, has significantly underperformed when compared to that of the S&P 500 and the Metals & Mining industry. The net income has significantly decreased by 92.5% when compared to the same quarter one year ago, falling from $146.00 million to $10.90 million.
  • The gross profit margin for CLIFFS NATURAL RESOURCES INC is rather low; currently it is at 21.56%. It has decreased from the same quarter the previous year. Along with this, the net profit margin of 0.99% significantly trails the industry average.
  • Net operating cash flow has significantly decreased to -$41.90 million or 110.11% when compared to the same quarter last year. In addition, when comparing to the industry average, the firm's growth rate is much lower.
  • CLF's debt-to-equity ratio of 0.61 is somewhat low overall, but it is high when compared to the industry average, implying that the management of the debt levels should be evaluated further. Despite the fact that CLF's debt-to-equity ratio is mixed in its results, the company's quick ratio of 0.57 is low and demonstrates weak liquidity.
