Amazon is introducing a new category on its marketplace for electronics accessories, into which many existing products will fall, and from early next year sellers will be charged a higher fee.

Currently merchants selling items which are listed under 'Camera and Photo' pay an eight per cent commission charge, but from next January these will be listed under 'Electronics and Accessories', a category which will attract a 15 per cent fee.

The news was broken to sellers on Wednesday, in an email which said the change was intended to improve "customer experience" by making it easier to discover similar products to that being searched for.

But one seller who wrote in to the eCommerceBytes.com blog claimed that many sellers might try to wrongly categorise their goods deliberately "to either get in a category with a lower Amazon referral fee, or to create a listing in a restricted category.

"The new fees may lead to more intentional mis-categorisation of products in order to avoid higher fees," he added.

Current electronic accessories product listings will be migrated to the new category automatically when it comes into effect on January 15 2013.
