We are the manufacturer & brand owner for all our products on Amazon. For some unknown reason, one of our products has a duplicate ASIN. This means when trying to create an inbound FBA shipment with this item, we are unable to. The platform blocks the item being sent due to a duplicated EAN.

I tried to use the merge ASIN tool but this did not work, so against my better judgement i reached out to seller support. They have (unsurprisingly) refused to merge the ASIN's because "the listing has been owned by retail contribution" (whatever that means!)

This is a very unhelpful response, given this is an item we manufacture and hold brand registry for. If they refuse to merge the very obviously identical ASINs then we will simply no longer sell the item on Amazon.

So - because someone in seller support wants to close their ticket as soon as possible, rather than help their customer, Amazon will lose approx £50k per year in sales this item generates. We will of course continue to sell the item on competing platforms.

I'd be grateful if a mod could assist with this, case ID: 11382142082
