DuPont secures ITC consent order banning Dawnsens’ Tyvek®-related imports for 10 years, reinforcing intellectual property protection and fair competition globally.
DuPont has confirmed that Dawnsens New-Materials Co. (commonly referred to as “Dangs”) has voluntarily agreed to a consent order issued by the U.S. International Trade Commission (ITC). Under the terms of this order, Dangs is prohibited from importing or selling in the United States any of the accused flashspun nonwoven materials or products incorporating those materials for a period of ten years. This development brings closure to DuPont’s ongoing litigation against the company at the ITC, which stemmed from allegations of trade secret misappropriation connected to DuPont’s proprietary Tyvek® technology.
The ITC, an independent and bipartisan U.S. government agency, is tasked with examining cases in which imported goods are suspected of harming domestic industries or violating intellectual property rights. In October 2024, DuPont formally requested that the ITC investigate Dangs, citing claims of both trade secret theft and trademark infringement relating to Tyvek® products. Along with its petition, DuPont sought an exclusion order that would prevent the entry of infringing materials into the U.S.
Speaking on the outcome, David Domnisch, Vice President and General Manager of DuPont™ Tyvek®, emphasized the company’s long-standing dedication to innovation and quality. “For decades, DuPont has been committed to delivering breakthrough technologies and trusted products. This is why our customers rely on genuine Tyvek® solutions for their most critical applications,” Domnisch said. He added that DuPont welcomed Dangs’ decision to accept the consent order and reaffirmed the company’s pledge to safeguard its intellectual property. “We will continue to protect our rights vigorously and pursue fair competition, not only in the U.S. but also across international markets,” he concluded.
The consent order is enforceable immediately and will be upheld by both the ITC and the U.S. Customs and Border Protection agency. These authorities will ensure that no prohibited materials or products from Dangs enter the U.S. market during the duration of the ban.
This outcome also affects other legal disputes involving Dangs. Multiple related cases have now been resolved through similar voluntary consent orders, effectively terminating litigation for those parties. However, the ITC investigation has not concluded entirely, as proceedings continue against several remaining respondents.
The ruling marks a significant milestone in DuPont’s broader effort to defend the integrity of its Tyvek® brand and its proprietary manufacturing processes. Tyvek® is widely known for its unique balance of durability, breathability, and protection, and is used in diverse applications such as medical packaging, protective apparel, and building construction. By securing the exclusion of unauthorized imports, DuPont reinforces its strategy of protecting customer trust, ensuring product authenticity, and preserving the competitive landscape within the global specialty materials market.
