Apple in a statement said today Chinese "high school students were made to work illegally overtime making the iPhone X by its supplierFoxconn violating local labour laws.
"We've confirmed the students worked voluntarily, were compensated and provided benefits, but they should not have been allowed to work overtime," Apple said in a statement.
The Financial Times in a report had said nearly 3,000 high school students were made to work for eleven hours a day in China's Zhengzhou city by iPhone's main Asian supplier Foxconn.
"When we found that some students were allowed to work overtime, we took prompt action. A team of specialists is on site at the facility working with the management on systems to ensure the appropriate standards are adhered to," Apple said.
The Financial Times in its report said the students from Zhengzhou Urban Rail Transit School were made to work to "log work experience required for graduation".
The report said the students, aged between 17-19, were being forced by their school to participate in the "internship".
Apple's statement said that the company had sent staff to the site to address the violations.
"Our policies do not allow interns to work more than 40 hours per week on programme-related assignments. Unfortunately, there have been a number of cases where portions of our campuses have not adhered to this policy," Foxconn said in a statement, adding that the interns accounted for a small part of the workforce.
Apple and Foxconn have been accused of poor labour practices in the past, five years ago Apple had said it had reduced the number of underage workers from its supply chain.
Zhengzhou, capital of China's Henan province is a major industrial town which hosts several technology companies.
