Selling on Amazon or Walmart can be a great business — but one of the biggest challenges for new and experienced sellers alike is sourcing authentic, legal, and profitable products from reliable U.S. wholesalers.
In this article, we’ll explain how to resell wholesale products legally and safely, and how Contarmarket helps thousands of resellers overcome the most common roadblocks.
Is It Legal to Resell Products Without Brand Authorization?
Yes — in the U.S., the First Sale Doctrine allows resellers to buy and resell genuine products without needing brand authorization, as long as the products are:
• Lawfully acquired
• Not materially altered
• Not misrepresented
That means if you purchase original products from a trusted U.S. wholesaler like Contarmarket, you can legally resell them on Amazon, Walmart, eBay, or your own website
What You Need to Resell on Amazon or Walmart
While you don’t need brand approval in most cases, platforms like Amazon often ask for:
• A commercial invoice from a U.S. distributor
• Proof that the product is authentic and comes from a verifiable source
• No marketing or promotional material included in the shipment
Contarmarket provides all of that:
• Invoices sent by email after each order
• Products shipped without any pricing or marketing materials
• Blind shipping available upon request
