Free warehousing vs storage fees: the second bill in fulfillment quotes

Most China fulfillment quotes hide a second bill: 3PL storage fees, charged by the cubic meter and the day once a free storage window runs out. We do not charge for storage on any timeline. That difference only matters once you know how the other bill gets calculated, so this guide walks through the math.

This is for a Shopify merchant pre-stocking a product to test demand, or comparing a "free storage" plan from a China dropshipping agent against a flat per-order fulfillment price.

How 3PL storage fees get billed (and hidden)

A dropshipping agent or 3PL rarely puts a storage number on its homepage. It shows up three ways instead.

First, as a free period with an expiry date. Several China based agents advertise free storage, then cap it at a fixed number of days per warehouse. Once that clock runs out, storage moves to a paid rate.

Second, as a rate per cubic meter (CBM) per day, not a flat monthly charge. A cubic meter is roughly the space inside a large moving box, about a meter on each side. The rate usually climbs the longer stock sits, so the second month after the free window costs more per day than the first.

Third, as a separate line for each SKU or variant. Most 3PLs will not let two different products share one storage slot, so a catalog with several sizes or colors pays the per CBM rate several times over.

A quote that says "free warehousing" without a day count or a per CBM rate attached is not comparable to one that spells both out. Ask for the number before you sign, not after the first invoice arrives.

Free storage that expires: what to check

Two of the larger China dropshipping platforms publish a free storage window, then a per CBM daily fee once it ends.

• HyperSKU: its free plan includes 30 days of free storage in China, and its paid tier extends that to 60 days, according to its own pricing page. What happens once that window closes is not stated on the same page.
• CJdropshipping: its published fee schedule gives 90 days of free storage in China, 60 days in the US, and 30 days in Poland, Germany and the UK. After that, storage is billed per cubic meter per day, climbing the longer stock sits, plus a peak season surcharge in some overseas warehouses.

None of this is hidden exactly. It usually sits on a separate pricing or fee schedule page, not the page that advertises the free storage headline. Before committing inventory, find that page and note three numbers: the free day count, the per CBM rate after it, and whether the clock resets with every new shipment or runs from the first arrival.

Our warehousing carries no storage fee and no day limit, in China or in a US location for a proven product. You pay per order that ships, so a slow month adds no separate storage line to check.

A 90-day cost comparison for one SKU

Say a home goods store orders 1,000 units of a $9 kitchen gadget to pre-stock and test a 90 day sell-through window. For this example, assume the stock takes up about 2 cubic meters of warehouse space, a reasonable size for a shipment of that quantity. The numbers below come from CJdropshipping's own published fee schedule, comparing two of its warehouse locations with different free windows.

In CJdropshipping's China warehouse, storage is free for the first 90 days. A 90 day test that sells through inside that window costs $0 in storage. Let the same stock sit 30 days longer and the 90 to 120 day tier bills $0.20 per cubic meter per day, so 2 cubic meters for 30 days adds $12.

In CJdropshipping's Germany warehouse, the free window is only 30 days. The same 90 day test spends its first 30 days free, then 30 days at $0.44 per cubic meter per day, then 30 days at $0.51 per cubic meter per day. That totals $57 in storage before the product has sold through a single unit.

Under warehousing with no time limit, the storage line stays at $0 whether the test takes 90 days or 190, because no clock is counting down and no warehouse location changes the number.

The point is not the exact dollar figure. It is that a free storage plan is a bet on your sell-through speed matching someone else's calendar, and that calendar can be shorter or longer depending on which warehouse the same company puts your stock in.

When paid storage still makes sense

Free or unlimited storage is not always the better deal. A brand moving thousands of units of one fast selling SKU every week turns inventory over fast enough that a per CBM fee barely registers, and a dedicated bin or pallet can speed up picking compared with shared shelf space. Some 3PLs price their storage specifically for that kind of volume, and it can work out cheaper per unit than a per order model once volume passes a certain point.

Paid storage can also make sense when the reason for holding stock is delivery speed rather than cost. A store shipping to customers from a warehouse already in their country cuts transit time in a way that per order fulfillment from overseas cannot match on its own. For a store at that stage, we can hold proven products in the US for domestic delivery under the same fee structure, so speed does not require adding a separate storage bill.

The deciding question is turnover, not the sticker price on the storage line. A SKU that sells out every two weeks pays little in storage under any model. A SKU still being tested, with an unknown sell-through, is the one a time-capped free plan penalizes hardest.

Questions to ask before you sign

Before pre-stocking with any fulfillment partner, get these five answers in writing, not only verbally on a call.

1. How many days of storage are free, and does the count start on arrival at the warehouse or on the first day of stocking?
2. What is the per cubic meter, per day rate once the free period ends, and does that rate increase the longer stock sits?
3. Is the free period per warehouse location, per SKU, or per shipment?
4. Does a peak season surcharge apply, and during which months?
5. Is a minimum order size or a minimum stock level required to qualify for free storage at all?

A quote that answers all five without a follow up email is one you can actually compare against a flat per-order price. For the wider list of checks worth running before connecting a fulfillment partner, see how to vet a China fulfillment partner.

Common mistakes

Reading "free storage" as unlimited. Most free storage windows run 30 to 90 days. Confirm the day count before ordering enough stock to outlast it.

Assuming the clock resets with every reorder. Some agents count from the original arrival date, not the latest shipment, so a top-up order can already be partway through its free window.

Comparing a $0 monthly platform fee without checking storage separately. A platform can charge no subscription fee and still bill heavily for storage. The two are separate line items on most fee schedules.

Pre-stocking a product before testing it. Ordering a large batch to save on unit cost before confirming the product actually sells adds a storage clock to inventory that has not proven it needs to exist yet. A smaller first order, described here for private label runs, removes that risk.

Ignoring per-SKU space. A catalog with several sizes or colors usually needs a separate storage slot for each variant, which multiplies the per CBM fee across a wider catalog than a single SKU count suggests.

Frequently asked questions

Does free warehousing mean there is no storage fee at all?

Yes, on our side. Warehousing carries no storage fee and no day limit, so a slow selling batch does not add a separate bill. Exact terms for your product and country come in a quote from an account manager.

How do China dropshipping agents calculate storage fees once the free period ends?

Most bill per cubic meter of space per day, with the rate increasing the longer stock sits. Published fee schedules show rates from around $0.20 up to several dollars per cubic meter per day depending on the warehouse country, plus a peak season surcharge in some cases.

What counts as a cubic meter for storage pricing?

A cubic meter is a space one meter on each side, roughly the size of a large moving box. A 3PL usually calculates it from the packed carton dimensions of your stock, not the product alone.

Should I pre-stock a product before I know it sells?

Test with a small batch or per-order fulfillment first. Once a product shows a repeatable sell-through rate, a pre-stock order becomes a math problem of storage cost against unit savings rather than a guess. See how to calculate dropshipping profit for the base numbers to plug into that comparison.

Does paying for storage ever cost less than a free but time-capped plan?

For a fast turning SKU sold in high volume, yes, because the stock rarely sits long enough to trigger a meaningful fee. For a product still being tested, storage with no time limit removes the risk of the sell-through running past someone else's clock.
