A single mislabeled ASIN can trigger an account-level investigation. If Amazon receives inventory with the wrong FNSKU, that unit gets linked to another seller's listing — or worse, it gets flagged as commingled inventory and you lose the Buy Box while Seller Performance reviews your account. We've seen sellers get restricted over labeling errors that were completely preventable.
At HM Prep, every FNSKU label is printed in-house using thermal printers that produce clean, scannable barcodes. Our team applies each label per Amazon's placement guidelines — covering any existing manufacturer barcodes — and then scans every single unit with a handheld reader to confirm the FNSKU matches the shipment plan. If something doesn't scan right, it gets flagged and re-done before it leaves our facility.
We also handle suffocation warning labels for poly-bagged items, expiration date labels for consumables and supplements, and cover-up labels when manufacturer barcodes need to be hidden. If your supplier shipped product with UPC barcodes and you need FNSKU coverage, we take care of it — no ambiguity, no guesswork.
