How to Fix Error 100325: Multi-Marketplace Listing Submission Failures
Error 100325 blocks bulk uploads when a multi‑marketplace spreadsheet is used for stores that require a single‑store template (e.g., Japan, Saudi Arabia) or contains unsupported characters. In a test case, a 5,000‑SKU upload to Amazon.ca, MX and UK stopped at 2,300 rows due to this error.
Overview
Sellers attempting to upload product listings with Amazon’s multi‑marketplace spreadsheet sometimes encounter error 100325, which stops the file from being accepted. The issue appears when a marketplace demands a single‑store template or when Amazon’s automatic translation engine cannot handle the supplied content. Resolving the error is essential for keeping international launch schedules on track.
Key Points
- Store‑specific templates required — Marketplaces such as Japan or Saudi Arabia only accept uploads that match their dedicated single‑store spreadsheet; using a combined file will trigger the error.
- Translation engine failure — If Amazon’s built‑in translator cannot convert a title or description into the target language, the submission is rejected with error 100325.
- Problematic characters cause rejections — Hidden HTML tags, bullet symbols, or non‑standard punctuation embedded in product fields disrupt the validation process.
- Re‑upload after correction — Once the offending content is removed and the proper template is used, sellers must submit the file again to clear the block.
- Impact grows with catalog size — Large inventories amplify the time spent fixing formatting, making early detection of template mismatches critical.
How to Resolve Error 100325
- Identify the target marketplace — Determine which Amazon store you are trying to list in; for example, a seller adding a new line to the German marketplace must verify that Germany supports multi‑store uploads.
- Download the correct single‑store template — From Seller Central, pull the spreadsheet that is labeled specifically for that marketplace (e.g., “Amazon.de Product Template”). Using the German template instead of a combined file prevents the system from rejecting the upload.
- Clean product content — Open the spreadsheet and scan every column for characters such as “&”, “%”, or HTML snippets like
<br>; replace them with plain text or remove them entirely. For instance, change “100 % cotton” to “100 percent cotton”.
Analysis & Recommendations
Why This Matters
A blocked upload delays international launches and forces sellers to manually split files and clean data, wasting time especially for large catalogs. For example, 2,300 rows were rejected before the issue was fixed, extending the rollout by days.
Key Takeaways
- Japan, Saudi Arabia and similar marketplaces only accept dedicated single‑store templates; using a combined file triggers error 100325.
- Hidden HTML tags, bullet symbols, and characters like “&”, “%”, “<br>” cause validation failures.
- In a real scenario, a 5,000‑SKU upload to Canada, Mexico and the UK halted at 2,300 rows because Canada requires a separate template and the file c...
