How to Fix Error 100609: Cost Increase Request Rejected in Seller Central
Error 100609 occurs when a seller's cost increase request exceeds Amazon's allowable thresholds for their product category. Sellers can resolve it by verifying their input for errors and resubmitting with a more moderate cost adjustment.
Overview
Amazon sellers who manage their product pricing through Seller Central may encounter Error 100609 when submitting a cost increase request. This error indicates that the proposed price adjustment has been flagged as too high relative to Amazon's internal thresholds for the product category. Understanding why this rejection occurs and how to address it can help sellers avoid delays in updating their pricing.
Key Points / What Sellers Need to Know
- Cost increases have category-specific limits — Amazon enforces maximum allowable percentage increases that vary by product category and store, and exceeding these limits will trigger an automatic rejection.
- Historical pricing data matters — Amazon compares your proposed cost against historical cost data and market benchmarks, so sudden large jumps are more likely to be flagged.
- Data entry errors can trigger the block — The system is designed to catch unusually large increases that may result from typos, incorrect currency conversions, or other input mistakes.
- Resubmission is straightforward — Once you adjust your cost amount to fall within acceptable ranges, you can resubmit through the same process without needing to open a support case.
Why This Error Occurs
Error 100609 is triggered when Amazon's automated pricing review system determines that a seller's proposed cost increase falls outside the acceptable range for their product category. There are several scenarios that can cause this. The most common is simply proposing an increase that exceeds the maximum percentage threshold Amazon has set for similar products in your store or category. Another frequent cause is a significant deviation from the item's current cost — for example, attempting to double or triple the cost in a single adjustment. Amazon's system also cross-references proposed costs against market benchmarks and historical pricing data for comparable items, so an increase that looks out of step with broader market trends may also be rejected. Finally, the system is built to flag unusually large jumps as potential data entry errors, serving as a safeguard before any major cost change is approved.

Key Takeaways
- Amazon enforces category-specific limits on how much you can increase product costs in a single request
- Common causes include data entry errors, wrong currency codes, and exceeding percentage thresholds
- Resubmitting with a lower, more moderate cost amount typically resolves the issue immediately
- Consider implementing large cost increases in smaller incremental steps over time
Recommended Actions
- →Double-check your currency code and cost amount for typos or conversion errors before resubmitting
- →Research competitor pricing in your category to ensure your proposed cost falls within a reasonable market range
- →If your costs have risen significantly, plan to adjust pricing in gradual increments rather than a single large increase
