CDSOA [Abstract]
Continued Dumping And Subsidy Offset Act [Text Block]	Note 17 - Continued Dumping and Subsidy Offset Act (CDSOA) 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 first three months of 2016, the Company recognized pretax CDSOA income, net of related expenses, of $47.7 million. In September 2002, the World Trade Organization (WTO) ruled that CDSOA payments are not consistent with international trade rules. In February 2006, U.S. legislation was enacted that ended CDSOA distributions for dumped 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 that funds were being distributed to the Company. On April 1, 2016, the Company received CDSOA distributions of $48.1 million in the aggregate, representing funds that would have been distributed to Timken at the end of calendar years 2011 through 2015. At March 31, 2016, the Company recorded a sundry receivable of $48.1 million, which was included in other current assets on the Consolidated Balance Sheet. 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 17 - Continued Dumping and Subsidy Offset Act (CDSOA)

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 first three months of 2016, the Company recognized pretax CDSOA income, net of related expenses, of $47.7 million.

In September 2002, the World Trade Organization (WTO) ruled that CDSOA payments are not consistent with international trade rules. In February 2006, U.S. legislation was enacted that ended CDSOA distributions for dumped 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.
