If imitation is the sincerest form of flattery, then InstaTrim owner Greg Amundson wishes his business wasn't so admired.
Over a decade, his made-in-Minnesota sealant grew to more than $3 million in sales last year.
But this year, sales are down by 35%.
Amundson and his lawyer attribute the abrupt decline to patent-infringing counterfeiters, mostly Chinese, who have launched about 30 similar products over the last several months on Amazon.com. InstaTrim had been relying on the e-commerce platform for about 80% of its sales.
"It's amazing how fast the counterfeiters are eroding our sales with look-alike, copycat products," Amundson said last week. "If you search Amazon for 'flex-trim' and 'caulk strip,' we used to show up on the first page, above the fold with InstaTrim products.
"Now you see all the copycat products that completely populate the first page, pushing us down. Fair competition is fair. But not the way they are doing it."
Amundson, a former homebuilder who exited during the housing collapse in 2008, spent years building Scandia-based InstaTrim from idea to cash-flowing growth company.
Amazon has long been criticized as an easy place for counterfeiters to knock off everything from soaps, baby formula, clothing, accessories and toys to auto and aircraft parts.
