Demystifying the Amazon Logistics & Distribution Machine

How does Amazon distribution work in 2026?

The Amazon distribution network operates as a massive, multi-tier infrastructure encompassing more than 175 fulfillment centers (FCs) across North America. In his 2023 shareholder letter, Amazon CEO Andy Jassy disclosed that the U.S. cost to serve fell by more than $0.45 per unit year over year in 2023 — marking the first reduction since 2018 — driven primarily by the company's regionalization restructure. Amazon has not disclosed specific dollar-level FBA cost-per-unit figures in primary filings.

For sellers, this structural shift means that inventory placement geography now drives profit margins as much as the landed cost of the shipment itself. In Q2 2025 year-over-year, the average distance packages traveled fell 12%, and total package touches dropped by almost 15%.

The FBA distribution system serves as the inbound gateway through single or multiple FCs. The foundational choice for inbound freight in 2026 sits between Amazon Global Logistics (AGL) — which packages an integrated door-to-door service from China to U.S. fulfillment centers — and independent freight bidding on a reverse auction interface.

The Lifecycle of an FBA Shipment

An FBA distribution shipment moves through six distinct stages: creating a shipment plan in Seller Central, prep and labeling, freight booking, ocean transit, FC receiving, and distribution to regional warehouses. The standard timeline for Chinese imports to the U.S. West Coast spans 18 to 25 days of ocean freight, plus 2 to 6 days of check-in under middle-mile demand aggregation, or 18 to 28 days under the standard placement model. Amazon cut U.S. inbound lead times by roughly 4 days in 2025 on the back of AI routing and expanded regional capacity.

The shipment plan starts with the SKU, unit count, and preferred FC. Amazon's algorithm returns one of three routing scenarios: an Amazon-optimized split across 5+ FCs, a partial split across 2 to 4 FCs, or single-FC delivery. Once approved, the system generates the required tracking and compliance barcodes.

Effective for inventory shipped on or after March 31, 2026, Amazon ended commingling — the practice of fulfilling customer orders from any seller's identical inventory in the closest fulfillment center. Labeling rules are now split by seller type:

• Brand Owners: Enrolled in Brand Registry with the Brand Representative selling role, they may continue using manufacturer barcodes (UPC, EAN, ISBN) for products that carry them; Amazon tracks these units virtually.

• Resellers & Non-Registered Brands: Must manually apply Amazon FNSKU labels to every unit, even when manufacturer barcodes are present.

• No Barcode Cargo: Products without manufacturer barcodes require Amazon FNSKU labels regardless of seller type.

Inventory shipped on or after March 31 without the required label is ineligible for fulfillment as commingled inventory and may be subject to receiving-side operational restrictions.

Regionalization of Amazon Warehouses: Impact on Shipping Costs

Regionalization represents the most profound structural shift in the Amazon supply chain over the past three years. Following the 2023 regionalization restructure, Amazon split the U.S. fulfillment network into 8 self-sufficient regional networks; industry observers report the count reached 10 by 2025. Local fulfillment — orders filled entirely within the region where the customer lives — rose from 62% to 76% of all U.S. orders after the 2023 change. Amazon's 2023 sustainability reporting also documented nearly 16 million driving miles avoided through this regional model.

The financial impact of this program became acute with the rollout of the updated Inbound Placement Service (IPS) fees. Better inventory placement remains a core pillar of the strategy. As Amazon CFO Brian Olsavsky noted during the Q1 2025 earnings call:

"Better inventory placement remains a top priority. Better placement drives more in-stock selection, reduces travel distances, and speeds up delivery."

According to Business Insider reporting on an internal Amazon all-hands meeting, Doug Herrington, CEO of Worldwide Amazon Stores, described the company's aggressive inventory positioning effort as "perfect placement." This initiative is powered by an AI forecasting model announced in June 2025, which leverages weather data, holiday signals, and regional demand patterns to achieve a 20% improvement in regional forecasts.

2026 Inbound Placement Fee (IPS) Schedule

Amazon's 2026 inbound placement fee structure is built around five size tiers, completely retiring the legacy oversize terminology. For minimal-split routing (sending to a single or restricted number of FCs), fees vary by weight band and destination region:

Amazon-optimized splits across 5+ FCs remain free for eligible shipments, forcing sellers to balance inbound transport costs against downstream placement fees.

AGL vs. Independent Freight Bidding on AiDeliv

Sellers routing inbound cargo must navigate a shifting regulatory and financial environment. AGL headline ocean rates often exclude downstream import and compliance costs such as customs continuous bonds, drayage, amendment fees, and exam-related fees. A standard $50,000 continuous customs bond commonly costs $400 to $600 per year for a creditworthy importer, with a broader range of approximately $250 to $750 per year depending on the importer risk profile and surety underwriting. Independent trade-press evidence does not support a blanket 50–100% markup claim; total cost layering depends heavily on cargo profile, exam exposure, and Importer of Record (IOR) compliance history. Foreign sellers without an established U.S. compliance history may face more friction as first-time or infrequent importers.

The U.S. tariff stack changed materially in early 2026 but did not collapse. On February 20, 2026, the Supreme Court invalidated all IEEPA-based tariffs in Learning Resources, Inc. v. Trump (6-3 decision). CBP stopped collecting IEEPA-based duties on February 24, and the administration replaced them with a temporary 10% ad valorem import surcharge under Section 122 of the Trade Act of 1974, effective through July 24, 2026 (Federal Register Proclamation 11012). Section 232 (steel, aluminum, autos) and Section 301 (China) tariffs are separate statutory regimes and remained fully active. The $800 de minimis exemption also remained suspended through Executive Order 14388, which was explicitly designed to survive any IEEPA invalidation.

For DDP economics, a fixed forwarder quote written early in the year may reflect a duty stack that no longer exists; auction-derived rates re-price against the current stack at the exact moment of bidding. Independent freight bidding through reverse auction interfaces like AiDeliv resolves this volatility. Shippers see the true all-inclusive landed cost on a single line, and the carrier with the best market-driven rate wins the auction.

Mid-2026 Inbound Shipping Comparison

FBA Inbound Requirements and Compliance

FBA inbound requirements tightened significantly across labeling, palletization, and fee structures. Effective January 1, 2026, Amazon discontinued all FBA prep and item labeling services in the U.S. marketplace, including for inventory routed through AWD, AGL, Amazon SEND, and the Supply Chain Portal. Every unit must arrive at the fulfillment center fully prepped, polybagged where required, and FNSKU-labeled.

Critical Exception: Shipments created in Seller Central before January 1, 2026, still receive prep and labeling services even if the inventory itself arrives after that date.

Shipments created after January 1 that arrive without proper prep are ineligible for reimbursement if damaged or untraceable, and prep/label defects are flagged in the Inbound Performance Dashboard. Third-party prep service costs generally break down by task:

• FNSKU Labeling Alone: Typically $0.20–$0.70 per unit.

• Polybagging: Typically $0.50–$1.50 per unit.

• Combined Label + Polybag: Typically $0.75–$2.55 per unit.

• Shipment Plan Creation: Typically charged per-shipment, not per-unit.

Furthermore, label placement is restricted strictly to flat surfaces (seams and corners trigger automatic rejection), and palletization must follow GMA Standard B at 40×48 inches, with zero overhang, heavy-duty stretch wrap, and a 72-inch height ceiling. Non-compliant shipments are refused at the dock, with return freight running $500 to $1,200 and causing weeks of inventory delays.

2026 FBA Fee Restructure Components

• Fulfillment Fee Increases: Rose by an average of $0.08 per unit effective January 15, 2026. This average masks an uneven distribution: small standard items priced above $50 saw an increase of +$0.51 per unit, while large standard items priced below $10 saw no change. Fulfillment fees in 2026 are calibrated to selling price as well as size.

• Inbound Defect Fee: Imposes a penalty range of $0.32–$1.74 for standard items and up to $5.72 for bulky items with labeling errors or routing mistakes.

• Low-Inventory-Level Fee: Now calculated dynamically per FNSKU, rather than per parent ASIN.

• Fuel and Logistics Surcharge: A 3.5% surcharge applies on top of fulfillment fees, implemented across split program timelines:

International Contrast: EU Low-Value Parcel Rules

Sellers cross-shipping into European channels face similar tight compliance. Effective July 1, 2026, the EU eliminates the €150 customs duty exemption for low-value parcels under Council Regulation (EU) 2026/382. A transitional simplified duty of €3 applies per item within a consignment where goods fall under different six-digit HS tariff subheadings (effectively per HS6 line in a parcel) for qualifying IOSS and postal consignments. This transitional mechanism runs from July 1, 2026, to July 1, 2028. No EU-wide handling fee is enacted as of May 2026; France operates a national €2 H7 declaration fee, but it is not an EU-wide measure.

Mastering the Inbound Stack

The 2026 compliance landscape pushes smart sellers to run a highly discrete, optimized process for each phase of the supply chain: a prep partner for compliant FNSKU labeling, a palletization partner for GMA-standard pallets, a freight forwarder with DDP capabilities for customs clearance, and a middle-mile demand aggregation partner to minimize check-in windows.

Sellers running everything through AGL pay a steep integration premium through placement fees and increased customs friction. Shippers who assemble their logistics stack from independent partners on a transparent freight exchange secure lower landed costs, broader rate visibility, and total control over their margins.
