AGL and FBA prep solve different parts of the shipment
Amazon Global Logistics is a transport and logistics service; China-based FBA prep is work performed on the inventory before it reaches Amazon. They are not direct substitutes. A seller can use a prep provider and then an AGL route, or combine another transport provider with the same prepared goods.
Amazon's global logistics information describes origin services, cross-border movement, customs clearance, and delivery to Amazon facilities within the offered scope. Check the current route and quotation. A transport booking should not be assumed to include every unit inspection, labeling, or packaging task.
Map the handoffs before asking which is cheaper
List the work from factory release to Amazon receiving: collection, consolidation, inspection, prep, carton data, export handling, main transport, import entry, and final delivery. Assign an owner and price basis to each stage.
Mark where goods change custody and where digital records change. If the prep provider finishes packing before the final shipment destination is confirmed, agree how labels and carton information will be updated without losing control of the goods.
Separate upstream product-compliance decisions from logistics execution. Neither a transport booking nor a warehouse's ability to attach labels establishes market eligibility, importer authority, or battery transport compliance.
Compare quotations for the same physical shipment
Use the actual number of units and cartons, packed measurements, weight, origin, destination, and service. A price per cubic metre alone is insufficient when minimums, chargeable weight, origin fees, or destination charges differ.
Ask each provider to identify included services, exclusions, and exception charges. Keep freight, prep labor, materials, storage, customs-related amounts, and final delivery visible. A quote that includes customs coordination may still exclude duties or a required bond.
Compare timing using the same starting and ending events. Factory-ready date, carrier departure, destination arrival, and saleable Amazon receiving are different milestones. Do not combine one provider's port-to-port estimate with another's door-to-door total. Record the event definitions beside each quoted period.
Keep prep ownership explicit under the current rules
US FBA stopped Amazon-side prep and item labeling from January 1, 2026. Amazon's developer announcement explicitly includes inventory routed through AGL, AWD, SEND, and the Supply Chain Portal. An AGL shipment therefore does not restore the old US prep service.
Arrange required work with the factory, seller, or a qualified prep provider before dispatch. Confirm the target marketplace's barcode and product-specific requirements. Other markets need their own current verification rather than inheriting the US date.
Check the completed package after all materials and labels are applied. Record counts and box contents for the transport handover. If a later consolidator repacks goods, confirm how it preserves the approved configuration and updates the records.
Evaluate control and recovery as well as ordinary cost
Ask how each arrangement handles a short receipt, a mislabeled SKU, delayed documentation, a missed collection, and a receiving discrepancy. Identify which party investigates and what evidence it needs. Multiple providers can work well when these boundaries are clear.
A single-provider arrangement can reduce coordination, but the seller still needs access to records and a clear scope. A combined arrangement can offer specialized prep or consolidation, while adding a handoff that must be managed. Neither structure is inherently superior for every shipment.
Pilot a representative batch and reconcile the actual charges, milestones, and received quantities. Use the result to update the next quote comparison. The decision is which combination of transport, preparation, and evidence supports the product at a defensible total cost, rather than whether an AGL label or a prep-center label sounds more comprehensive.
