Overview

Amazon sellers who adjust product costs in Seller Central sometimes encounter Error 100607. The error appears when Amazon’s pricing engine judges a submitted cost change as exceeding market‑acceptable limits, and it can halt a seller’s ability to update prices until the issue is resolved.

Key Points

• Price‑threshold validation — Amazon automatically compares each cost update against current market data; a 23 % increase on a $12.99 item may be blocked if it falls outside the platform’s acceptable range.
• Competitive‑price check — The system benchmarks the proposed price against the average of the three lowest competing offers; a price that is 40 % higher than that benchmark often triggers the error.
• Historical‑price conflict — If a product’s price has remained within a $2‑wide band for the past 30 days, a sudden jump to a new price outside that band is likely to be rejected.
• Rapid‑submission detection — Submitting three separate price‑increase requests within a 15‑minute window can flag the account, even when each individual increase is modest (e.g., two 5 % hikes).
• Preference for incremental changes — Amazon’s algorithm favors step‑wise adjustments; splitting a 15 % increase into three 5 % updates over three weeks typically passes validation.
• Category‑specific limits — Certain high‑turnover categories such as “Home & Kitchen” have tighter thresholds (often 10 % max per change) compared with “Industrial Supplies,” where larger swings are tolerated.

How Error 100607 Works

1. Submission review — When a seller uploads a new cost, Amazon’s pricing engine pulls real‑time data from the product’s category, recent sales, and competitor listings. Example: A seller tries to raise the cost of a Bluetooth speaker from $29.99 to $38.99; the engine fetches the three lowest competing prices, which average $31.50.
2. Threshold comparison — The engine calculates the percentage difference between the proposed price and the market benchmark. If the gap exceeds the pre‑set threshold for that category, the request is flagged.
