Introducing three mandatory ASIN attributes, effective October 26, 2021


To provide a better shopping experience for our customers, effective October 26, 2021, we’re introducing the following three mandatory attributes for listings created one at a time or in bulk.

  • Net Content: A new attribute set for eight Product Types (PTs)
  • Item Form: A previously optional attribute that will become mandatory for 86 PTs
  • Number of Items: A previously optional attribute that will become mandatory for 154 PTs

With these changes, all ASINs for select PTs must have these attributes populated when you submit new ASINs or update existing ASINs. Failure to populate these mandatory attributes will prevent any new selection creation in the relevant PTs after October 21, 2021. Note that this will not de-list any selection that you have listed before October 21, 2021. However, to provide a seamless shopping experience for customers, we strongly recommend that you update this information on existing listings. If you have ASINs in your inventory in any of the select PTs that don’t have an 'Item Form' or 'Number of Items' value, you may begin updating these attributes now.

Additionally, we are adjusting the allowed values for the Unit Count Type attribute for 138 PTs. For more information, see Net Content, Item Form, and Number of Items attributes details page.


What does this motherlode of proprietary jargon even mean?

If changes like these were rolled out with plain-English explanations, it might reduce the hundreds if not thousands of Seller Support cases they are sure to generate.


Did you click on the link for a more wordy version?


PT = Product Type… just in case you skimmed and were confused like I was. I mean, I’m still hella confused…


You can just check this link for the list of the Product Types

If you don’t like checking links, expand the (stupidly long) list below



It was translated from Chinese to English. Since Amazon is heavily investing in them coming on the platform, to list their products at manufacturer price.

They now write their jargon first in Chinese, then translate in english.

The bots don’t speak english, hence the translation doesn’t make any sense.


What’s next amazon… we might need to go to customers homes to clean and cook for them to make it a awesome customer experience :thinking:



Is this an expansion of this: or seperate?


None of this affects categories in which I sell, BUT

WHY are we rolling out changes like this in the build up to fourth quarter? Seems like a lot of busy work to lay on sellers who are already up to their ears in holiday prep.


Sounds like its for new listing, not existing.

When i saw the notice, i tried to make sense of it, but its like reading the Bridge column in the newspaper. The words are in English, but when put together, dont convey something that means anything.

My first thought is that this must apply to stuff like shampoo, and when i saw the list, was pretty much correct.


my brain is not real linear when it comes to reading forms I read this and laughed at myself thinking this was a horizontal list at first and not a bunch of vertical data



This is yet another reason to suppress listings with no fix. I have had 15-20% of our listings suppressed for supposedly missing information that I can neither add nor fix. We have constantly contacted SS as well as asking for the capture team to discuss how we can get the listings unsupressed. Never got a reply from them. But darned if I dont keep getting applications to send my inventory to FBA…


Sooooo unnecessary busywork. Got it.


Is this a partially-decoded Rosetta Stone?


This list of affected product types is at section 7 of this page.


Well we know (as of writing this) 41 of the 2300 managed to find the like button, but not the blue words.


In Summary: More reasons to give nonsensical product suppressions or even product removals.


I think both. As soon as you try to update an existing listing it will force you to make this change with an updated template.


Since JB semi-retired, TPTB have showed a disturbing tendency to increase metrics, invent new statistics/attributes and rule sellers lives in every niggling way possible. They seems to feel the more complicated the better.

Especially find @aisglic’s comment disturbing. No wonder some of the list in question made absolutely no sense!!


I like this change. You SHOULD be listing your Count, Weight, Volume as part of an accurate product description.

This change is probably to try to address some shady sellers trying to scam or deceive sellers as to what they will be getting… like a half empty tube of toothpaste maybe?
