What shipping options do I have for Amazon FBA?
Two main inbound shipping options: FBA Small Parcel (individual boxes, per-pound rates): Use for smaller shipments or when you need faster transit. Typical carriers: UPS, FedEx, USPS. FBA LTL (Less than Truckload): For larger shipments on pallets, often more cost-effective for 200+ lbs. You can also use Amazon's合作 carrier program for discounted rates. Choose based on: shipment size, urgency, and cost.
How does dimensional weight affect my shipping costs?
Carriers calculate shipping based on the greater of actual weight or dimensional weight (size). Dimensional weight = (Length × Width × Height) / 139 (for domestic US). A 12x12x12 box weighs 5 lbs but has 12.4 dimensional weight, so you'd be charged for 13 lbs. This is why optimizing packaging size dramatically reduces costs. Amazon charges fulfillment fees based on the greater of unit weight or dimensional weight after accounting for packaging.
What are the main Amazon FBA fulfillment fees?
FBA fulfillment fees (per unit, based on size tier): Standard size (under 1 lb): $3.22-3.48. Standard size (1-2 lbs): $3.48-4.24. Standard size (2-3 lbs): $4.24-5.00. Oversize items: $8.13+. Additional fees: Storage (January-September: $0.78/cubic foot, October-December: $2.40), Removal/disposal fees ($0.50-1.50/unit), Returns processing (15% of item price).
How do I calculate my total FBA shipping cost per unit?
Total FBA cost per unit = Inbound Shipping Cost + FBA Fulfillment Fee + Storage (if applicable). Inbound shipping to Amazon: Calculate cost from supplier to Amazon warehouse. Fulfillment fee: Based on size/weight. Storage: Average days in stock × daily rate. For example: $500 shipment of 100 units from China to Amazon warehouse ($5/unit) + $3.48 fulfillment fee + $0.05 storage = $8.53/unit FBA cost before product cost.
What's the difference between FBA and FBM for shipping?
FBA (Fulfilled by Amazon): You ship inventory to Amazon, they handle storage, picking, packing, shipping, and customer service. Cost = Inbound shipping + FBA fees + Storage. FBM (Fulfilled by Merchant): You ship directly to customer from your warehouse/ supplier. Cost = Shipping from supplier + Your packing + Shipping to customer. FBA is typically 20-30% more expensive but saves significant time and provides Prime eligibility. Calculate both to decide which works for your margins.
