There is no way to know before you get quotes, and be suspicious of anyone who says otherwise. Amazon markets GWD as up to 45% cheaper than US AWD, but that is a comparison against US warehousing rather than a Chinese warehouse, and 'up to' is a ceiling rather than a rate. It implies a GWD range of roughly $9.30 to $16.95 per cubic meter per month, which overlaps the usual China 3PL band of about $5 to $15. Expect storage to be a wash within a few hundred dollars per run and decide on capability instead.
Andrew Erickson is the founder of Inventory Hero. He has spent years working with Amazon FBA sellers on demand forecasting, restock planning, and the cash flow side of running a private-label brand. Inventory Hero exists because every spreadsheet-based inventory system he tried eventually broke — usually right before Q4.
Store excluded categories such as Consumer Electronics, battery-powered goods, and high-value items; ship to any channel or country rather than only Amazon's network; do custom prep, kitting, relabeling, and inspection; and let you pull inventory back out or redirect it. GWD is reported to run a bonded flow into Amazon, where units are committed once the export declaration is filed, though Amazon has not published that rule publicly.
When is Amazon GWD the better choice?
When effectively all of a SKU's volume ends up in Amazon US, the category is on Amazon's allow list, and demand is steady enough to tolerate a multi-week replenishment leg. In that case you get automatic replenishment into FBA, one vendor instead of two, and reported eligibility for the fee waivers Amazon ties to replenishing through its own upstream nodes.
Can you use both GWD and a China 3PL?
Yes, and split routing is common. Send the allow-listed, Amazon-only SKUs through GWD to get the automatic replenishment and fee relief, and keep the excluded categories, multichannel SKUs, and anything needing custom prep at a 3PL. The cost is two origin relationships to manage and an inventory picture that has to roll both up.
Amazon GWD versus a China 3PL is not really a price comparison, because neither side's rate is knowable before you request a quote. Both store your inventory at manufacturing origin, and their plausible storage ranges overlap heavily. The actual split is what happens on the way out: GWD is a bonded, one-way flow committed to Amazon's network, while a 3PL can ship your units to any channel, any country, or back to the factory. The short version: if every unit ends up in Amazon US and the category qualifies, take GWD; anything else, buy the optionality.

The row that decides most cases is the second one. If a meaningful share of your catalog is Consumer Electronics, battery-powered, or high-value, GWD will simply refuse it, and the comparison ends before it starts. Check your catalog against GWD eligibility before you spend time modeling costs.
Model both as the same four-part shell, then fill in your own quotes:
Origin cost = (storage rate x cubic meters x months) + inbound handling + outbound handling + freight and customs to FBA
GWD. Storage is priced per cubic meter per month. On top sit per-carton processing on the way in and out, an export declaration charge per inbound shipment plus a per-carton outbound charge, and AGL transportation billed separately. Amazon does not publish the AGL rate card, so you cannot complete this model until you have onboarded and quoted a lane, which is itself a point against it during evaluation.2
China 3PL. Storage is also per cubic meter per month, commonly quoted around $5 to $15 for longer-dwell contract storage, with short-dwell shared-warehouse day rates running higher, and often a free period of one to four weeks bundled with a consolidation service.3 Handling in and out is per carton or per CBM, and your freight forwarder quotes the ocean leg and customs entry competitively.
Those directional 3PL numbers move with city, contract term, and dwell time, so treat them as a sanity check on a quote rather than a budget.
CBM
Cubic meter, the volume unit origin warehouses and ocean freight price against. One cubic meter equals 35.31 cubic feet, which is why an unconverted comparison against Amazon's per-cubic-foot US rates is misleading.
Because neither side's number is knowable in advance, and the honest arithmetic says so.
On the GWD side, Amazon publishes no per-cubic-meter rate. What it publishes is a comparative claim: storage up to 45% below US AWD. Work that against the AWD base rate for the East, Southeast, and South Central regions ($0.48 per cubic foot, or about $16.95 per cubic meter) and the sound inference is a range, roughly $9.30 to $16.95 per cubic meter per month, not a point.4 "Up to" is a ceiling. Any article quoting you a single confident GWD rate has quietly turned a best case into an expected value.
On the 3PL side you have a market band of roughly $5 to $15 for contract storage, which is real but wide, and which you collapse to one number the moment you request a quote.
Put those together honestly and the conclusion is not "GWD costs about the same as a 3PL," which would be an unfalsifiable claim dressed up as a finding, given that almost any number lands inside a $5 to $15 band. The conclusion is narrower and more useful: on a run of this size, storage is a few hundred dollars either way, the ranges overlap heavily, and handling plus freight will swing the total more than storage does. That is enough to stop treating cost as the deciding input, without pretending to a precision nobody has.
To size it for your own catalog: take a run of 3,000 units at 0.35 cubic feet each, which is 29.7 cubic meters, held four months. Four months of storage is roughly $1,100 to $2,000 on the GWD range and roughly $600 to $1,800 across the 3PL band. Those overlap almost entirely. Meanwhile a single ocean container quote moves by more than that spread between one forwarder and the next. Run your own volume through the CBM calculator to get the cubic meters, then price both shells with real quotes rather than with either of these ranges.
Three things, and they are structural rather than fixable:
The exit is one-way. GWD operates in a bonded setup, so once the export declaration is filed on a unit it cannot move back into China.2 No rerouting to a domestic Chinese channel, no sending it back to the factory for rework or repackaging. If a batch has a labeling problem discovered after declaration, your options narrow to fixing it in the US.
The catalog gets split anyway. Unless your entire range is allow-listed, some SKUs cannot use GWD, and you end up managing a second origin relationship for them. At that point one of GWD's main advantages, having a single vendor, is already gone.
Timing control costs you the waivers. The fee relief Amazon attaches to GWD replenishment is tied to the automatic mode, where Amazon decides quantity and timing.5 Keeping manual control generally forgoes it. A 3PL never had waivers to offer, so it never presents you that trade.
Two things, and both are real work rather than real money:
You own the replenishment. Every shipment into FBA is yours to book, document, and track, and you are the one watching FBA cover to decide when to move units. GWD's automatic mode removes that job entirely. For a lean operator running dozens of SKUs, that labor is not trivial.
You lose the fee waivers and the integration. No relief on aged or low-inventory-level charges, no inventory visibility inside Seller Central, and reconciliation between your 3PL's system and your FBA balance becomes a recurring task rather than a non-issue.
Both are the same trade AWD versus a 3PL presents domestically, shifted upstream by an ocean. If you have already made that call for US-side buffering, your answer here is probably consistent with it.
One line: choose GWD when effectively all of a SKU's units end up in Amazon US, the category is allow-listed, and demand is steady enough to survive a multi-week replenishment leg. Choose a China 3PL the moment any of those three fails.
Concretely, lean GWD when:
Amazon US is the whole business for that SKU, or close to it.
The catalog clears the category, size, and weight gates cleanly.
You want fewer vendors and are happy to hand Amazon the replenishment timing.
Aged-inventory or low-inventory-level charges are already costing you enough that the waivers matter.
Lean 3PL when:
You sell off Amazon in any serious way, including your own site, Walmart, TikTok Shop, or wholesale.
Part of the catalog is excluded, especially electronics and anything with a lithium cell.
You need inspection, kitting, relabeling, or repacking at origin, which is common on a first production run with a new supplier.
You want the ability to redirect or hold inventory as conditions change, including tariff timing.
You are still building trust with a supplier and want a third party physically checking goods before they cross an ocean.
Most sellers who evaluate this end up splitting rather than picking. The allow-listed, Amazon-only SKUs go through GWD for the automatic replenishment and fee relief. The excluded categories, the multichannel SKUs, and anything needing prep stay with a 3PL.
That works, with one condition: your inventory picture has to roll both up. Two origin nodes plus in-transit plus AWD plus FBA is five places a unit can be, and a restock decision made on the FBA number alone will be wrong in both directions. The rule for counting them, which applies to either route, is in Amazon GWD explained: origin stock goes in your total position and your cash, never in your days of supply.
Amazon GWD and a China 3PL both solve the same problem, holding a full production run near the factory instead of importing all of it at once, at storage rates close enough that price rarely decides. GWD buys integration, automatic FBA replenishment, and fee waivers, at the cost of a category allow list and a bonded flow you cannot reverse. A 3PL buys optionality, any category, any channel, any destination, plus prep and inspection, at the cost of running the replenishment yourself.

Directional China origin warehousing rates, commonly about $5 to $15 per cubic meter per month for longer-dwell contract storage, with short-dwell shared-warehouse day rates running higher (roughly $1 to $1.25 per cubic meter per day after a free period) and free periods of roughly one to four weeks often bundled with consolidation services. Compiled 2026-08-07 from published China 3PL and consolidator rate guides including China Top Freight ("China Warehouse Costs: Storage and Logistics", chinatopfreight.com), Top China Freight ("Warehouse in China Cost: Complete Guide", topchinafreight.com), Tonlexing ("China Warehouse Storage Fees", tonlexing.com), and Epic Sourcing ("China 3PL Warehousing and Fulfillment: The Complete Guide", epicsourcing.co). These are third-party market rates that vary by city, contract term, dwell time, and services, not published Amazon fees. Treat the band as a sanity check on a quote, not as a budget, and note that a band this wide cannot by itself establish where any specific program's rate sits.
Amazon Warehousing and Distribution base monthly storage, $0.48 per cubic foot in the East, Southeast, and South Central regions, effective January 15, 2026. At 35.31 cubic feet per cubic meter that is about $16.95 per cubic meter, so a 45% reduction implies roughly $9 per cubic meter per month.
