Trying to sell on Amazon for 5 months – CPSIA attribute can’t even be set!

I’ve been trying to get ONE product listed on Amazon for 5 months now. It’s a plush backpack under my own brand. Fully tested, certified, and cleared in the US and Europe.
All documents are submitted, including the CPC and lab reports (costing thousands). Still, Amazon rejects the listing.

Why?

Because they keep asking me to update the CPSIA attribute.

Here’s the joke:
The “CPSIA warning” field doesn’t even exist when editing the listing.
It’s not shown in the UI, and uploading a flat file doesn’t help either — Amazon just keeps replying with the same automated message asking for a CPSIA warning attribute that I cannot physically set.

And it’s even more frustrating because:

• My product doesn’t have small parts.
• It’s not for kids under 3.
• There is no choking hazard.
• The product is set for Teens (13+).
• The correct value should be “No warning applicable”, but THERE’S NO WAY TO SET IT!

Meanwhile, I see cheap, unbranded, obviously non-compliant Chinese products listed and selling without issues — no documentation, no problems. But my tested, compliant, legitimate product? Blocked for months.

Amazon, what are we supposed to do?
