FCPA fine

On 17 May 2011, Tenaris agreed to pay the US Department of Justice US$8.9 million in the first ever deferred prosecution agreement with the Securities and Exchange Commission.

A settlement was reached after Tenaris voluntarily disclosed details of illicit payments made to officials of an Uzbek state-controlled oil firm which were not properly recorded in the company's financial statements.

According to the Department of Justice, Tenaris paid bribes through local agents to obtain competitor’s bid information, which it used to submit revised bids in order to secure tenders.

An official at the Department of Justice said: "The company's immediate self-reporting, thorough internal investigation, full cooperation with SEC staff, enhanced anti-corruption procedures and enhanced training made it an appropriate candidate for the Enforcement Division's first Deferred Prosecution Agreement."

Violence in Mexico

On 24 December 2013, over 100 disgruntled ex-employees of Tenaris Tamsa in Veracruz stormed the facilities and were attacked with sticks, pipes and stones by supporters of the worker's union, "Sindicato Union y Progreso", or SNUP. These workers had been dismissed by the company in 2012 for their violence after attempting to elect a new union leader, Jose Carlos Guevara Moreno, "El Profe." Pascual Lagunes Ochoa, a convicted fellon who as of April 2016 remains as the union leader of SNUP, and often attends and speaks at public events. The ex-employees are currently in a legal battle against the company, having been denied their severance.
