Shipping from China to Amazon FBA

A wrong box label, or a side longer than the destination allows, can leave the cartons sitting at receiving.

Ship from China to Amazon FBA only after the sealed cartons match the live shipment in the seller account. That match covers the barcode the account requires, one box label per carton, and the box limits Amazon published for US FBA.

Shipping from China to Amazon FBA is a release decision: the sealed cartons have to match the live US shipment plan before the cargo leaves China. Amazon’s News_Amazon post on Seller Forums, fetched October 17, 2026, sets the US FBA box limits effective June 20, 2025 at 36 inches long, 25 inches wide, 25 inches high, and 50 lb. A Dougal_Amazon reply on that same thread keeps Amazon Warehousing and Distribution boxes at 25 by 25 by 25 inches and 50 lb. Amazon’s 2016 packaging quick reference, which prints an expiry of June 30, 2016, says Amazon will not serve as importer of record. On the ICC page reviewed the same day, Incoterms 2020 are eleven terms that allocate cost, risk, and obligations, and the costs for a given rule are listed at article A9/B9.

The shipment plan itself lives in the seller account. The handoff from a China order into that account is the subject of China sourcing for Amazon sellers.

What must match before the cartons leave China?

The physical cartons and the live shipment record have to name the same goods. Build the shipment after the sellable unit, the pack quantity, and the ready quantity are fixed. If the factory changes the units per carton after the label file exists, the box-content lines and the cartons diverge.

Amazon’s 2016 quick reference, printed to expire June 30, 2016, says each box in the shipment needs its own label printed from the shipping queue, and that the FBA shipment label and the carrier label both have to stay uncovered and scannable. The same file says to cover the original manufacturer barcode on a labeled unit, and that a box holds inventory from only one shipment ID. Confirm those points in the live shipment workflow, because that file is past its printed expiry. The prep steps that sit on the unit, before the carton is closed, are in Amazon FBA prep and labeling in China.

Keep a label register: which label went on which carton, with the SKU, the quantity, the gross weight, and the three sides measured after sealing. A repack means a new line in that register. Moving a printed label onto a different carton breaks the match.

The inspection that samples packed cartons before release is pre-shipment inspection in China. Close the findings, or accept them in writing, before pickup.

Which box limit applies to this destination?

Use the limit for the building that will receive the cartons.

For US FBA, the News_Amazon post says that starting June 20, 2025 the maximum box length increases from 25 inches to 36 inches, and that the maximum box dimensions are then length 36 inches, width 25 inches, height 25 inches, and weight 50 lb. Dougal_Amazon, replying on that thread, wrote that the implementation date of June 20, 2025 is accurate and that the FBA shipping and routing requirements help page had already been updated. The same reply says the change is for FBA shipments only. AWD boxes remain within 25 by 25 by 25 inches and a 50 lb weight limit.

Rule of thumb. If the longest side exceeds 36 inches on a US FBA inbound carton, repack before anyone prints box labels. The announcement sets 36 inches as the length, and a label file built for the old carton count will not match the new boxes.

Rule of thumb. If any side exceeds 25 inches and the destination is AWD, hold the carton. Dougal_Amazon kept the AWD limit at 25 by 25 by 25 inches.

One seller reply on the same thread reported an error in the shipment screen when a side was over 25 inches. That reply is not the announcement. Read the live screen on the day you create the shipment. If the screen still rejects a side the announcement allows, the screen is the file Amazon will receive.

The 2016 quick reference said boxes containing multiple standard-size units must not exceed 25 inches on any side, and it allowed a single oversize unit above 50 lb with a Team Lift label. That file prints an expiry of June 30, 2016. Do not treat the 25-inch-on-every-side line as the current US FBA length. The June 20, 2025 announcement is the later public statement of the length.

How do you test one carton against the limit?

Sort the three measured sides. Call the longest side L, the middle side W, and the shortest side H. Call the scale weight G. The carton is inside the US FBA announcement when all four lines are true:

L <= 36 in

W <= 25 in

H <= 25 in

G <= 50 lb

Volume = length * width * height

Worked example. Assume a sealed carton measures 24 in by 16 in by 12 in and the scale reads 18 lb. Volume = 24 * 16 * 12 = 4608 cubic inches. L is 24, which is under 36. W is 16 and H is 12, both under 25. G is 18 lb, under 50 lb. All four checks pass. The announcement does not publish a dimensional-weight divisor, so this volume is geometry, not a freight rate.

Amazon’s 2016 file says that, for its partnered small-parcel carrier, the entered dimensions are used to calculate dimensional weight, and that this weight determines fees when it exceeds the actual weight. The file does not print the divisor, and it is past its printed expiry.

Chargeable weight = the greater of scale weight and dimensional weight

Worked example. Assume the forwarder writes a dimensional weight of 26 lb on the same 18 lb carton. Chargeable weight = the greater of 18 lb and 26 lb, which is 26 lb. The 26 lb is an assumption written on a hypothetical quote. It is not an Amazon divisor and it is not a price.

Put that chargeable weight next to the goods, duty, and destination lines in the landed-cost formula. The landed cost calculator is the worksheet for those lines. This page does not publish a freight rate.

Who is the importer, and which Incoterm is named?

19 CFR 101.1, on the eCFR display current as of October 15, 2026, defines importer as the person primarily liable for the payment of any duties on the merchandise, or an authorized agent acting on that person’s behalf. The section lists the consignee, the importer of record, the actual owner when an actual owner’s declaration and superseding bond have been filed under 19 CFR 141.20, and the transferee of warehoused merchandise. eCFR states that it is not the official legal edition of the CFR.

Amazon’s 2016 quick reference says Amazon, including its fulfillment centers, will not serve as importer of record for any shipment of FBA inventory, of any size, value, origin, or product. The same section says Amazon will not be responsible for duties, taxes, or shipping costs, and that shipments are required to use Delivered Duty Paid terms. Any shipment arriving with collect charges would be refused. The file prints an expiry of June 30, 2016, so confirm the live import help in the seller account before the booking. The checks that belong on that confirmation are in the DDP and importer of record checklist.

Under 19 CFR 141.1(b)(1), payment to a broker covering duties does not relieve the importer of liability if the duties are not paid by the broker. Hiring a forwarder in China does not, by itself, make that forwarder the importer.

Incoterms 2020, on the ICC page reviewed October 17, 2026, are eleven three-letter terms for business-to-business contracts for the sale of goods. The page describes a clear allocation of cost, risk, and obligations, and it says the costs for a given rule appear at article A9/B9 of that rule. The supplier quotation should name the rule. A blank rule leaves the cost split unset. The commercial invoice and the packing list have to agree on quantity and description before that quotation is final. Use the invoice and packing list cross-check for that comparison.

When should several factories share one booking?

Share one export booking when the cartons are going to the same market and you can reconcile them in one place before the labels are printed. A consolidation warehouse receives, counts, and holds the short or damaged cartons instead of loading them. The fields for that hold are in China warehousing and consolidation.

Consolidation adds a receiving step. It helps when the factories finish on different days, or when one factory should not see another’s goods. It hurts when the hold has no owner. Unknown cartons stay out of the booking.

Unreleased cartons = received cartons - released cartons

Worked example. Assume 40 cartons arrive and 37 match the live shipment plan. Unreleased cartons = 40 - 37 = 3. Those 3 stay behind. A booking that lists 40 cartons does not match a release of 37.

Hold days = release day - receipt day

Worked example. Assume receipt on day 1 and release on day 6. Hold days = 6 - 1 = 5. Storage and a second label print fall inside those 5 days. The equation does not produce a storage rate or a freight rate.

A split replenishment, some cartons by air and the balance by sea, is a second booking with its own carton data. Compare the two on chargeable weight and on the day units can be sold, which is later than the day a carrier delivers to the fulfillment center.

What should the freight quote separate?

Choose air courier, air freight, sea freight, or a split only after the forwarder has the sealed measurements and the destination. How shipping from China works separates the mode choice from the Amazon label problem. This page stays on the FBA release.

A usable quote names where the clock starts and where it stops. Factory pickup, export handling, the sailing or the flight, customs examination, deconsolidation, the delivery appointment, and Amazon receiving are different stages. A range that runs port to port is a different promise from a range that runs factory to available inventory.

Ask the quote to separate origin charges, main transport, customs services, duties and taxes, destination handling, and the appointment. Confirm whether the forwarder prices the lane by actual weight, volumetric weight, CBM, or minimum shipment tier.

What record stops the release?

Release is the decision to let the carrier take the cartons. Hold the cargo when any line below is open.

• The shipment plan in the seller account is the current one, and the destination is FBA or AWD as you intended.
• Each required unit barcode scans, and it belongs to that SKU.
• Each carton has the unique box label generated for this shipment, and the carrier label is still readable.
• Count, weight, and the three sides reconcile to the shipment record.
• The inspection findings are closed or accepted in writing.
• The Incoterms rule, the importer, the broker, and the duty payer are written down.
• The quote states its scope, its chargeable basis, and the start and end of the transit range.

Track three later events separately: carrier delivery, Amazon check-in, and units available for sale. Delivery to the building is not the same event as a unit becoming sellable. Reconcile a shortage against the carton register before the next production run.

Method and sources

This page was checked on October 17, 2026. The US FBA box limits are taken from Amazon’s News_Amazon post on Seller Forums, “Maximum box length for FBA orders to increase,” which states an effective date of June 20, 2025. The AWD limit and the confirmation of that date are from Dougal_Amazon’s reply on the same thread. A separate seller reply on the thread reported a shipment-screen error above 25 inches. That reply is reported as a seller reply.

Label, barcode, shipment-ID, importer, DDP, and partnered-carrier dimensional-weight sentences are from Amazon’s Packaging and Shipping Inventory to Amazon quick reference. The PDF prints a copyright of 2016 and an expiry of June 30, 2016. Its 25-inches-on-any-side line is cited only as the older statement the June 2025 announcement replaced for US FBA length. Seller Central help pages for shipping and routing returned a login shell on October 17, 2026, so they were not used as text.

Incoterms sentences are from the ICC Incoterms 2020 page fetched the same day. Importer and duty sentences are from the eCFR display of 19 CFR 101.1 and 141.1, which eCFR dated as current through October 15, 2026. eCFR says it is not the official legal edition of the CFR.

The 24 by 16 by 12 inch carton, the 18 lb scale weight, the 26 lb dimensional weight, the 40 and 37 carton counts, and the five hold days are worked examples with stated assumptions. They are not a shipment, a fee, or a test. No cached search-result file for this query was on hand, so no new search-result purchase was made.
