CDSOA [Abstract]
Continued Dumping And Subsidy Offset Act [Text Block]	Note 19 - Continued Dumping and Subsidy Offset Act (CDSOA) The U.S. Continued Dumping and Subsidy Offset Act ("CDSOA") provides for distribution of monies collected by U.S. Customs and Border Protection ("U.S. Customs") on entries of merchandise subject to antidumping orders that entered the U.S. prior to October 1, 2007, to qualifying domestic producers where the domestic producers have continued to invest in their technology, equipment and people. During the third quarter of 2016, the Company recognized CDSOA expense of $0.2 million. During the first nine months of 2016, the Company recognized pretax CDSOA income, net of related expenses of $53.6 million. In September 2002, the World Trade Organization ruled that CDSOA payments are not consistent with international trade rules. In February 2006, U.S. legislation was enacted that ended CDSOA distributions for imports covered by antidumping duty orders entering the United States after September 30, 2007. Instead, any such antidumping duties collected would remain with the U.S. Treasury. CDSOA has been the subject of significant litigation since 2002, and U.S. Customs has withheld CDSOA distributions in recent years while litigation was ongoing. In recent months, much of the CDSOA litigation that involves antidumping orders where Timken is a qualifying domestic producer has concluded. As a result, the Company was notified by letters dated March 25, 2016, and June 24, 2016 that funds were being distributed to the Company. On April 1, 2016, and July 1, 2016, the Company received CDSOA distributions of $48.1 million and $6.3 million, respectively, in the aggregate, representing funds that would have been distributed to the Company at the end of calendar years 2011 through 2015. While some of the challenges to CDSOA have been resolved, others are still in litigation. Since there continue to be legal challenges to CDSOA, U.S. Customs has advised all affected domestic producers that it is possible that CDSOA distributions could be subject to clawback. Management of the Company believes that the likelihood of any clawback is remote.

Note 19 - Continued Dumping and Subsidy Offset Act (CDSOA)

The U.S. Continued Dumping and Subsidy Offset Act ("CDSOA") provides for distribution of monies collected by U.S. Customs and Border Protection ("U.S. Customs") on entries of merchandise subject to antidumping orders that entered the U.S. prior to October 1, 2007, to qualifying domestic producers where the domestic producers have continued to invest in their technology, equipment and people. During the third quarter of 2016, the Company recognized CDSOA expense of $0.2 million. During the first nine months of 2016, the Company recognized pretax CDSOA income, net of related expenses of $53.6 million.

In September 2002, the World Trade Organization ruled that CDSOA payments are not consistent with international trade rules. In February 2006, U.S. legislation was enacted that ended CDSOA distributions for imports covered by antidumping duty orders entering the United States after September 30, 2007. Instead, any such antidumping duties collected would remain with the U.S. Treasury.

CDSOA has been the subject of significant litigation since 2002, and U.S. Customs has withheld CDSOA distributions in recent years while litigation was ongoing. In recent months, much of the CDSOA litigation that involves antidumping orders where Timken is a qualifying domestic producer has concluded.

As a result, the Company was notified by letters dated March 25, 2016, and June 24, 2016 that funds were being distributed to the Company. On April 1, 2016, and July 1, 2016, the Company received CDSOA distributions of $48.1 million and $6.3 million, respectively, in the aggregate, representing funds that would have been distributed to the Company at the end of calendar years 2011 through 2015.

While some of the challenges to CDSOA have been resolved, others are still in litigation. Since there continue to be legal challenges to CDSOA, U.S. Customs has advised all affected domestic producers that it is possible that CDSOA distributions could be subject to clawback. Management of the Company believes that the likelihood of any clawback is remote.
