If the inquiry finds that the minerals might have come from one of the countries, the company must investigate the source and file a report to the SEC. The report also must be posted on companies' websites.
For the oil and natural gas payments, companies must file reports to the SEC no later than 150 days after the end of their fiscal year. The requirement starts for fiscal years ending after Sept. 30, 2013.
The oil industry's biggest lobbying group argued that the requirement could put U.S. companies at a competitive disadvantage and hurt the U.S. economy. The rule will give foreign oil companies access to confidential information about their U.S. competitors, John Felmy, chief economist of the American Petroleum Institute, said in a statement.
Paredes and SEC Chairman Mary Schapiro excused themselves from voting on that rule to avoid potential conflicts of interest.
