I have been dealing with this issue over a year now. I have spoken to over 50+ seller support specialist and multiple leadership team supervisors and nobody can will see this issue through.

My ex best selling ASIN is a automotive air filter. It is a genuine Automotive airfilter direct from the manufactuter. I typically send in 50+ units at a time to FBA packed together in a box. The packaging is direct from the manufactuer and involves zero prep. The items stack perfectly and take alot of misuse to actually become damaged. The item is not perishiable and also does not expire. Over the last 14 months Amazon will receive my shipments in and within 48 hours of being checked in all 50+ units become unsellable then are deemed defective. Originally I labled my own products and thought the issue had something to do with my labeling. I have created a new GS1, I have closed and opened new listings. I even changed over to Amazon's labeling service then again switched it over to Manufactuer labeling where I continued to have the same issue no matter what detail in the process changed. No matter what I changed everything would still turn to defective.

I have shipped 50+ units, twice to three times a month for the last 14 months. Every shipment (25+ shipments) the exact same situation happens.

When I reach out to Amazon I continue to get the same generic canned responses with no accountability or insight.

Gerneric response's

Response 1. Due to there not being any stock in the warehouse to investigate we are unable to investigate this situation. Ofcourse, there is no stock to investigate on the shelf. It never makes it to the shelf Its all deemed defective....SMH

Response 2. There are several reasons that items become defective....Perishiable's, expired products, damaged in the warehouse, product details, blah blah blah.. none of these apply.

Another small detail that I find odd is typically Amazon codes defective products to one of thier single letter codes that describe the issue. Example K, A, C

In all of the shipments they have never coded it. I find this very odd and so does each Manager that looks into this mentions this detail.

I am now over a year into this issue and over 100 hours of phone and emails going back and fourth with zero progress. Reading through other sellers struggles that are similar it is typically always label related. Being that its a manufactuer labeled product really kills any thesis that this is something on my side but I am willing to try anything at this point.

At this point my best selling ASIN is now my worst selling ASIN and I am several thousand dollars in the hole with Amazon fees, shipping fees, processing fees and the fact it can take 6 months to get defective products returned. Any suggestions, tips, tricks or insight is welcomed. I am desperate to get this solved and get my life back on track
