Tools & Home Improvement category available in Feeds API is missing in SP-API Product Type definitions

[coderpang]

Hi team,

We found an inconsistency between the legacy Feeds API and the SP-API product definition endpoints.

🧩 Background

In the legacy Feeds API, we could successfully use the category Tools & Home Improvement when submitting feeds (e.g., product uploads).

However, when using the SP-API Search / Product Type definition endpoints (such as /definitions/2020-09-01/productTypes or the newer searchDefinitionsProductTypes), there is no corresponding ProductType that matches the semantic meaning of Tools & Home Improvement.

❓ Issue

• The category name Tools & Home Improvement appears in legacy API usage and in Amazon Seller Central UI.
• But in the SP-API product type definitions, there is no top-level ProductType entry with that name or equivalent.
• It makes it difficult to determine what ProductType developers should use when they want to list under Tools & Home Improvement—especially for items that clearly belong to that category.

🔍 Example

A developer might expect to find something like:

"TOOLS_AND_HOME_IMPROVEMENT"

or multiple ProductTypes clearly grouped under Tools & Home Improvement semantics.

But instead, the available ProductTypes from the SP-API definitions do not include this, and relevant tooling docs/examples don’t address this gap.

❗ Impact

• API clients cannot reliably map listings that were previously categorized as Tools & Home Improvement via Feeds API to an SP-API ProductType.
• It increases developer confusion and complicates integration workflows, especially for category-specific tooling or validation.

📌 Questions

1. Is there a reason why Tools & Home Improvement is not present in the SP-API product types?
2. Should developers instead map to multiple lower-level ProductTypes (e.g., tools, hardware, electrical, etc.)?
3. If so, is there official guidance or a canonical mapping for Feeds categories → SP-API ProductTypes?

Thank you for your help!
