OAKLAND — Federal prosecutors have placed their crosshairs on an international company based in Hayward, for allegedly selling iPhone accessories with forged Apple logos on them.

On Monday, the U.S. Attorney’s Office filed charges of trafficking counterfeit goods and covering or obscuring a required mark of importation against the company Bizslink LLC and its owner, Sean Tang, of Boston. The trafficking charge carries a maximum penalty of five years in federal prison and a fine of $500,000, while the second charge, a misdemeanor, carries a maximum one-year term.

Federal authorities describe Bizslink as an import business that sold electronics, car parts and Apple products, including iPhone accessories like protector shells and screen covers.

Phone calls and emails to the company seeking comment were not immediately returned.

Charging documents allege that the business, and Tang, “knowingly used the counterfeit iPhone mark, the counterfeit Apple mark and the counterfeit Apple logo on and in connection” with iPhone products.

The company’s website says it has offices in Hayward, the United Kingdom, as well as Shenzhen and Shanghai, China. A section of the site boasts it pays “particular attention to product quality control.”

“We will only continue a working relationship with the supplier as long as their products are of high quality,” the site reads. “Our purchase department will personally sample and examine products before each shipment.”
