Understanding Amazon.com USA FBA Fee Logistics Tiers

USA FBA Size & Weight Categories

In the USA marketplace (**Amazon.com**), products are classified into precise size categories including **Small Standard** and **Large Standard** tiers. Bids are computed using dead weight in ounces (oz) and shipping dimensions.

Make sure to keep your dead packaging size as small as possible. Slipping into a higher Large Standard tier can raise fulfillment shipping expenses by over **$1.20 per package**, destroying margins on low-price items.

Reverse Logistics on US Markets

Amazon USA buyers are accustomed to extremely fast, hassle-free returns. Standard return processing on cosmetic or apparel items usually charges the seller a **Return processing fee** matching the outward shipping cost.

Additionally, many returned goods are classified as customer-damaged or unfulfillable, forcing complete cost write-offs. Use this USD-based model to ensure you have enough buffer to accommodate a **6% to 12%** return rate safely.
