Amazon's December 2025 updates brought critical changes for FBA sellers, from extended holiday cutoffs to peak fees lingering until Jan 14, 2026, and USPS proof-of-shipment shifts hitting FBM hard. Don't miss the extended returns through Jan 31—brace for Q1 cash flow hits and inventory risks like auto-liquidations.​​

Key Dates

Dec 23, 2025: Final FBA/Seller-Fulfilled Prime cutoff for holiday delivery.​

Dec 24, 2025: USPS postmark rules tighten, switch to pickup scans for FBM proof.​

Jan 14, 2026: Peak fees end; recalculate margins immediately.​

Jan 31, 2026: Holiday returns deadline.​

Hidden Traps

Liquidation/donation defaults can wipe out aged stock without warning—review settings now. Bundling enforcement is stricter; undocumented kits risk suppression and forced disposal. DSP keyword targeting shines for mid-funnel ads but demands tight ROAS monitoring to avoid budget burns.​

Action Plan

Sweep dispositions: Remove, reprice, or liquidate aged inventory in 48-72 hours.​

Harden FBM proofs: Mandate carrier scans over drop-off slips.​

Audit bundles: Fix packaging/LOA gaps or pause listings.​

Amazon October 2025 Seller Updates: What You Need to Know

October shook up the Amazon selling game with crucial changes across advertising, fulfillment, compliance, and AI tools. Here’s the gist:

Advertising shifts: New advanced bidding tools and Amazon Marketing Cloud inside Ads console enable smarter targeting but also tougher competition and rising costs.

Virtual Multipacks: Amazon’s new feature lets sellers create multipacks without repackaging, boosting cart size and margin potential.

FBA fee changes: Weight-based pricing and peak season fees hit heavier items harder. Returns fees target high-return categories.

Compliance ramps up: Stricter origin and bundling rules mean faster suspensions for non-compliance.

AI-powered analytics: New Seller Assistant tools bring actionable insights and automation to optimize pricing, inventory, and ads.

Supply chain risks: Tariff threats and sourcing flexibility have never been more critical.
