Yes, you can potentially use wholesale suppliers from the UK to ungate categories like Grocery and Beauty on Amazon.com, as long as the invoices meet Amazon’s requirements. Ensure that the invoices are from reputable suppliers, clearly show the product details, quantities, and your company name and address, and include the supplier’s contact information. Additionally, the products must comply with US regulations and standards, such as FDA compliance for Beauty and food safety for Grocery. It’s advisable to confirm the eligibility of your UK suppliers for ungating on Amazon.com beforehand to avoid delays or rejections.
