Amazon Is Retiring the Legacy Sponsored Brands Product Collection API. Here Is Your Migration Timeline.

When Amazon launched its Global Warehousing and Distribution facility in Shenzhen in April 2026, it was the first step in a stated vision: store inventory at origin in China, replenish US FBA on demand, and handle everything in between, customs, cross-border logistics, and fulfillment center delivery, through a single integrated flow. Three months later, the program has expanded meaningfully. On July 16, 2026, Amazon adds a second GWD facility in Shanghai, covering the Yangtze River Delta, one of China's largest manufacturing and export hubs. And for any brand that ships inventory to a GWD location between July 1 and December 31, 2026, the first 30 days of storage are free. That combination - a new location closer to more manufacturers, plus a free storage window heading into Q4, makes this the right moment to take GWD seriously if you have not already. What GWD Actually Does GWD is built for brands that manufacture or source from China and currently ship large quantities of inventory to the US before demand materializes. The traditional model requires estimating demand weeks or months in advance, shipping bulk into FBA, paying US storage fees, and hoping the forecast holds. Get it wrong in either direction, and you are either paying long-term storage fees on slow-moving stock or running out during a peak period. GWD inverts that logic. You store bulk inventory in China, at a facility in Shenzhen or Shanghai, close to your manufacturer, and Amazon automatically replenishes into the US FBA based on actual demand signals. Amazon handles the entire process: storage, export documentation, customs clearance, cross-border shipping, and delivery to US fulfillment centers. Sellers who enrolled in AWD during Q4 2025 saw more than 13% more shipped units and a greater than 30% reduction in out-of-stock days during the quarter. The cost advantage is real at the storage line. GWD rates are up to 45% lower than US Amazon Warehousing and Distribution, and inventory can reach US fulfillment centers up to seven days faster when paired with Amazon Global Logistics. The "up to" qualifier matters — your actual savings depend on your specific products, volumes, and replenishment frequency. Storage is one line in the total landed cost, not the whole picture. AGL ocean freight, FBA fulfillment fees, and customs charges all appear on separate invoices. What Is New in July Two additions change the practical accessibility of GWD for brands not already using it. The Shanghai facility opens July 16. For brands manufacturing in the Yangtze River Delta, which covers a significant portion of China's electronics, apparel, and consumer goods production, the Shenzhen facility required transporting inventory to a location that may not be close to the factory. Shanghai removes that friction for a large segment of China-based supply chains. Amazon has also confirmed the Shanghai location will eventually support shipments to European and Japanese fulfillment centers, not just US FBA — making it the foundation for global distribution from a single inventory pool. The FOB incoterm is now supported across all GWD locations. Under FOB terms, you obtain separate invoices for export declaration and origin port handling charges, documentation that supports the export tax rebate process for China-based sellers. This was a meaningful barrier for some sellers under the previous CIF-only structure, and removing it broadens the range of supply chain arrangements GWD can accommodate. The 30-day free storage promotion applies automatically. Any shipment received at a GWD facility between July 1 and December 31, 2026, gets the first 30 days of storage at no cost. After 30 days, standard GWD storage fees apply. No activation is required; the promotion triggers on receipt. Why the Timing Matters The free storage window runs through December 31, which means it covers the entire Q4 peak season — the period when US FBA storage fees are at their highest. FBA peak storage fees apply from October 15 through January 14, 2027, at $2.40 per cubic foot for standard-size units, up from $0.87 in the off-peak window. The 3.5% fuel and logistics surcharge applies on top of that. For brands currently holding Q4 inventory in US FBA ahead of demand, the cost comparison is straightforward: paying GWD's China-based storage rates on bulk inventory versus paying FBA peak fees on the same inventory sitting in US warehouses waiting to be sold. The math will vary by category and velocity, but the directional advantage is clear for slow-moving or pre-positioned stock. Sellers who enrolled in AWD and enabled automatic replenishment also keep paying the off-peak monthly storage rate through October 31, 2026 — two weeks into the peak fee window — giving AWD and GWD a structural cost advantage over holding the same inventory directly in FBA. What to Consider Before Using GWD The program is genuinely useful for the right supply chain profile. It is not the right fit for every seller. The most important constraint to understand before sending inventory to GWD is the bonded warehouse rules. Once goods are stored at GWD and an export declaration is completed, Chinese customs regulations prevent the inventory from moving back into China. The only direction is forward — into US FBA. If a SKU moves slowly or demand shifts, your options narrow fast. This is not an Amazon policy; it comes from Chinese customs law, but the operational impact falls on the seller. The 30-day free storage promotion is a useful window to test GWD with a single shipment before committing significant inventory. Amazon explicitly suggests this: start small, test with one shipment, no long-term commitment. That is sensible advice given that real-world replenishment performance, customs timing, and total cost will differ from Amazon's published examples depending on your specific products and logistics setup. The auto-replenishment feature is the operational backbone of GWD; it calculates and recommends restocking plans based on sales data, so inventory flows into FBA ahead of stockouts rather than on a fixed schedule. That feature is now fully launched as part of the July expansion. If you want manual control instead, that option remains available. How to Get Started The process runs through Seller Central. Go to Send to Amazon Warehousing and Distribution, select a ship-from address in China, choose a GWD distribution center (Shenzhen or Shanghai from July 16), select the SKUs and quantities you want to send, and submit your booking. The free storage promotion applies automatically once the shipment is received. Before sending, review the full terms and eligibility criteria at the Global Warehousing and Distribution fees help page in Seller Central. Confirm your importer of record setup is in place and that your user permissions for inventory and reporting access are configured correctly. The combination of a new Shanghai location, FOB support, and 30 days of free storage heading into Q4 is the clearest signal yet that Amazon is serious about making GWD a standard option for China-sourced supply chains, not just an experiment for early adopters. For brands that have been watching from the sidelines, the cost and risk of testing it right now is low. If you want to stay updated on Amazon changes, subscribe to our blog.

Amazon just made a quiet but structurally significant change to how the Buy Box, formally called the Featured Offer, works. Starting July 2026, Amazon is removing seller eligibility requirements for the Featured Offer, with the change rolling out gradually across all Amazon stores globally and completing by the end of 2026. The EU and UK change takes effect on July 20. No action is required from sellers — existing offers are included automatically. On the surface, this sounds like good news for everyone. In practice, it changes the competitive dynamics of the Featured Offer in ways that require attention.   What the Old System Looked Like Under the previous system, a seller first had to clear a standalone performance-based eligibility check before their offer could even enter the Featured Offer pool. Only sellers who passed that gate entered a second pool where offers were ranked against each other on price, delivery speed, and service quality. Two steps: gate, then rank. That gate locked out sellers with weak account health metrics - high Order Defect Rates, chargeback issues, and poor Voice of the Customer scores. It also, as many sellers have documented for years, occasionally locks out sellers who appear to have perfectly healthy accounts and could never get a clear explanation why. Amazon's stated reason for the change is straightforward: they determined the first eligibility step was "no longer delivering additional value to customers, so we're removing it." What Actually Changes The performance metrics — chargeback rate, Order Defect Rate, Voice of the Customer complaints — do not disappear. They move from functioning as a pass/fail gate to functioning as direct weighted inputs inside a single ranking formula, alongside price, delivery speed, and service quality. One contest instead of two steps. The practical consequence is twofold. Sellers who were previously locked out of the Featured Offer entirely - including some brand owners who could not win the Buy Box on their own branded listings despite being the sole seller — now re-enter the pool automatically. For those sellers, this removes a frustrating and opaque barrier. For sellers currently winning the Featured Offer, the pool just got wider. Sellers who priced defensively against a gated field now face a wider competitor set. Competitors who were previously ineligible are now competing in the same ranking contest. Being considered for the Featured Offer does not guarantee your offer will be featured. Amazon is explicit about this. The ranking criteria — competitive pricing, delivery speed, performance — remain unchanged. The gate is gone; the competition is not. The Advertising Exposure You Need to Know About Amazon Ads documentation is explicit: without the Featured Offer, Sponsored Products, Sponsored Brands, and Sponsored Display serve zero impressions, even while Campaign Manager shows the campaign as delivering. This means any competitor who was previously ineligible for the Featured Offer was also invisible in your ad auctions. Once they re-enter the Featured Offer pool, they re-enter the advertising auction simultaneously. Brands that have been competing in a partially gated field will see the auction widen at the same time their Featured Offer competition widens. That is a double exposure - more Featured Offer competition and more advertising competition - arriving from the same policy change. What to Watch and What to Do The immediate action is to pull your 30-day Featured Offer percentage by ASIN, re-baseline your repricing floors, and watch daily as previously gated competitors rejoin the pool. For brands using automated repricing, check that your floor prices are set against the actual competitive set you now face, not the gated pool that existed before July. On account health: performance signals now score inside the ranking formula rather than blocking entry to it. Your Order Defect Rate, chargeback rate, and Voice of the Customer data directly affect your Featured Offer competitiveness now, not just your account standing. Maintaining clean account health metrics is no longer just a compliance exercise; it is a direct competitive input. On pricing: this change does not reward defensive pricing. The ranking formula has always weighted competitive pricing heavily. With a wider competitor pool, the pricing signal becomes more important, not less. A seller priced above the competitive floor can still win the Featured Offer if their performance metrics are stronger than lower-priced competitors, but that tolerance band is not publicly documented and narrows as competition increases. The Featured Offer is the most important piece of real estate on any Amazon listing. Amazon just changed who can compete for it. Understanding what that means for your specific ASINs, repricing strategy, and ad campaigns is the work that needs to happen now, not after you notice a drop in Buy Box share.
