Customs notified Spin Master that they had detained the shipment of counterfeit Zero Gravity vehicles, valued at $30,000, because they appeared confusingly similar to the Zero Gravity Micro.
The counterfeit cars had been manufactured in China and were on route to retailers in the US.
The counterfeit RC cars will now be destroyed. In recent years, Spin Master has made strenuous efforts in its anti-counterfeiting campaign.
"Enforcing our intellectual property rights and fighting against counterfeits coming into the United States is a drain on our time, money and resources," said Christopher Harrs, General Counsel for Spin Master.
"To be able to have Customs recognize counterfeits at ports of entry and take action is a huge benefit to us as creators of original product and as a result, a great benefit to our industry as a whole."
Anton Rabie, CEO of Spin Master added: "We feel it is important, not just for our company, but also for our legitimate importers, distributors and the public that we raise awareness of this problem. As creators of original product, we are constantly facing illegal knock-offs being purchased from China by retailers in North America because the knock-offs are cheaper.
"The product may look the same but invariably they have cut safety corners to bring down the cost. Spin Master will continue to work diligently with Customs and Border protection organizations throughout the world to enforce our intellectual property rights against counterfeiters."
