Amazon FBA storage fees for US sellers are $0.78 per cubic foot per month for standard-size and $0.56 per cubic foot for oversize from January through September, rising to $2.40 and $1.40 respectively from October through December (Amazon Seller Central, Monthly inventory storage fees, data checked 2026-08-20). That base rate is only half the story: a separate storage utilization surcharge of up to $1.88 per cubic foot stacks on top for sellers whose inventory turns too slowly. ...

An Amazon fulfillment center code is a short identifier — commonly four characters, three letters plus a digit, such as MKC6 — that Amazon assigns to one of its buildings. Amazon’s own published API model defines the field bluntly: “An Amazon fulfillment center identifier created by Amazon.” (Selling Partner API, Fulfillment Inbound v0 model, published by Amazon in its amzn/selling-partner-api-models repository; checked 2026-08-20.) Two consequences follow, and they are the whole point of this page. You can read a code well enough to know roughly which metro area a shipment went to. You cannot use a code — or any third-party address list built from codes — to decide where to ship, because the only valid destination is the one your own shipping plan hands you at the moment you build it. ...

Amazon Multi-Channel Fulfillment (MCF): What It Costs Per Order, and When a 3PL Wins Amazon Multi-Channel Fulfillment ships your off-Amazon orders out of the same FBA inventory pool, on its own separate rate card — and the fee per unit falls by roughly half once an order contains four units. On Amazon’s rate card dated June 1, 2026, a small standard unit of 4 oz or less costs $7.34 to fulfil as a one-unit Standard order and $3.64 per unit inside a four-unit order. That 50.4% spread decides whether MCF is expensive or cheap for your catalogue, and most comparisons skip it. Every figure below was read off Amazon’s own rate card and help pages on 2026-08-20. ...

A normal Amazon third-party seller account cannot list a digital download — no PDFs, no templates, no asset packs, no license keys. An Amazon moderator states it plainly in Seller Forums: “unfortunately, third party sellers are not able to sell digital downloads, only Amazon Retail can create this type of listing” (Rose_Amazon, Selling Digital Goods on Amazon, checked 2026-08-20). Digital money on Amazon is made through separate programs, each with its own sign-up, its own catalog, and its own definition of “digital product.” One accepts a manuscript file. One accepts a design and then prints a physical shirt. One accepts audio. Two of the routes that older guides still list have closed since 2024, and one more could not be verified as alive at all on 2026-08-20. This guide separates them route by route, with the official wording for each. ...

Amazon FBA prep requirements come in two layers, and most rejected shipments fail because the seller only read one of them. Layer one is general packaging — every unit must arrive in a single sealed package, with a scannable barcode and no old barcodes visible. Layer two is product-specific prep — bagging, bubble wrapping, opaque bagging, or set labeling, triggered by what the product actually is. This guide lays both out by product type, with the numbers that matter: 1.5 mil minimum poly bag thickness, a 5-inch bag opening as the suffocation warning threshold, and warning text sized by the total length plus width of the bag. ...

Amazon FBA reserved status means your units are physically in Amazon’s fulfillment network but temporarily held out of your Available quantity. Amazon names exactly three reasons for it — Customer Orders, FC Transfers, and FC Processing — and in Amazon’s own words, “reserved inventory is a normal part of your FBA business.” Only one of the three carries a published timeframe: FC Transfers, which Amazon says “could take 22 to 25 days to complete.” ...

When sellers say they want to ship all their Amazon FBA inventory to one warehouse, they are describing an option Amazon actually sells: minimal shipment splits. You send one shipment to one destination, Amazon redistributes the units across its network afterwards, and you pay a per-unit FBA inbound placement service fee for the privilege. The free alternative — Amazon-optimized shipment splits — costs $0 in placement fees but requires you to send to four or more locations and to meet a carton-uniformity requirement many small sellers cannot meet. So this is an arithmetic question, not a policy question: one warehouse is cheaper whenever the placement fee costs less than the extra freight you would pay to split. ...

In every public Amazon channel we checked on 2026-08-19 — its seller-facing content, its research site, and its own forums — Amazon has not announced, named, or documented a search algorithm called “A10.” The term was created by the seller and agency community, not by Amazon. Every page that ranks for the phrase is a third-party interpretation of ranking behavior — useful in places, but not an official specification, and not something you can look up in Amazon’s own documentation. ...

Amazon Warehousing and Distribution (AWD) comes to Germany, France, Italy, Spain and the United Kingdom on 20 August 2026. That date, and those five countries, come from Amazon’s own announcement to European sellers. Everything else circulating about the launch — European storage rates, box size and weight limits, warehouse locations, an earlier inbound date — is not on any Amazon page a logged-out visitor can read, as of 2026-08-18. This page separates the two. It quotes what Amazon has stated, records exactly which official URLs were checked and what they returned, and names the numbers that could not be confirmed rather than borrowing them from resellers of the news. If you want the mechanics of the programme itself — the five-stage flow, the US rate structure, the dwell-time maths that decides whether bulk storage pays — that is the Amazon AWD guide; this page is only about the European opening. ...

Amazon FBA Delivery Window: The 7-Day Cross-Border Rule Reported for 1 September 2026 The rule Amazon has actually published says a cross-border FBA inbound shipment needs a 14-day delivery window and a domestic one needs 7 days, and only sellers on a non-partnered carrier have to enter it at all. Trade press reported on 13 August 2026 that international shipments into the UK, Germany, France, Italy and Spain move to a seven-day window from 1 September 2026 — but as of 18 August 2026 we could not open an Amazon-published page that says so. That gap is the whole point of this guide: the change is credible and worth preparing for, and it is also not something you should treat as confirmed policy until Amazon’s own page or your own Seller Central notification says it. ...

Item Highlights is an Amazon listing field that holds 125 characters of shopper-facing product detail and displays beneath the product title — in search results and on the product detail page. Its content is indexed for search. Since August 10, 2026 it sits in the same place on desktop and on mobile, rather than sharing the title line on desktop. It arrived alongside the 75-character title cap, and together the two fields carry the 200 characters of product information a listing used to fit into one long title. ...

Amazon does not publish a fixed timeline for when a submitted review appears. We checked the five customer-facing help pages that govern reviews on 2026-08-17 — Customer Reviews, Submit a Review, Community Guidelines, Understanding Customer Reviews and Ratings, and the Anti-Manipulation Policy — and none of them states a number of hours or days. What Amazon does state is the gate: on the Submit a Review page, “Your submission must follow our Community Guidelines or we won’t post the review,” and on Understanding Customer Reviews and Ratings, “Before posting a review, we check if it meets our Community Guidelines.” Every “24 to 72 hours” figure you have read is a third-party observation, not an Amazon commitment. This guide separates the two problems hiding behind the same sentence, lists the filters Amazon actually documents, and covers the seller routes Amazon explicitly permits. ...
