Overview

Amazon’s logistics network for vendors is undergoing significant changes in 2024 – and if you manage Amazon Vendor Central accounts, you can’t afford to fall behind. From new shipping and pallet labelling requirements to shifting chargeback policies, these updates demand swift adaptation. In an episode of the Marketplace Masters webinar, Amazon logistics expert Christopher Khoo (Founder of KhooCommerce) unpacked the latest developments and shared actionable strategies for vendors. In this comprehensive guide, we synthesise those insights into a clear game plan for Amazon agency professionals and vendor managers. You’ll learn what the changes mean, how to comply and optimise operations, and why proactively refining your processes now will pay off in fewer shortage claims, lower vendor chargebacks, and a stronger bottom line. Let’s dive into the new Amazon vendor logistics landscape – and how to stay ahead of the curve.

The Evolving Amazon Vendor Logistics Landscape

Inflation, Supply Chain Shifts, and Amazon’s Response: The past year has been turbulent for supply chains. Vendors have grappled with high inflation and global logistics disruptions, though some pressures (like sky-high container rates) eased in 2023. Amazon has responded by tweaking both Seller (3P) and Vendor (1P) operations – for instance, introducing new FBA inventory placement fees that impacted brands running hybrid models (both 1P and 3P). On the Vendor side, Amazon’s retail team has been “pretty ruthless” about enforcing compliance to keep its fulfillment centres efficient(Stop Profit Leaks: How to Tackle Amazon Vendor Chargebacks). Now in 2024, a series of Amazon-driven logistics changes is reshaping how vendors ship products. The biggest headline? A major update to the Advance Shipment Notification (ASN) process, often called “ASN version 2.”

Why Amazon Is Upping the Requirements: Amazon’s business runs on razor-thin timelines and sophisticated automation. Every vendor shipment needs to arrive just-in-time and be processed with minimal human touch. The Advanced Shipment Notification is essentially an electronic packing list that tells Amazon exactly what’s coming in each shipment – down to each box and item. Amazon uses ASN data to plan inbound loads and even to auto-receive cartons via scanners and conveyor systems. If an ASN is missing or incorrect, the shipment gets flagged for manual processing, which is slower and prone to errors (leading to those dreaded “inventory not received” claims).

In short, Amazon’s goal with these logistics updates is to boost accuracy, speed, and efficiency in its supply chain. As Chris Khoo noted, when vendors comply with new standards, Amazon can receive goods more smoothly – “they don’t have to open up each box… they just scan the label and let the robots handle it”, whereas non-compliant shipments “have to get humans involved” and often result in discrepancies. The takeaway for vendors: staying compliant not only avoids penalties, it helps Amazon help you by reducing errors in receiving.

Breaking Down the New ASN Requirements (AKA “ASN Version 2”)

What Is an ASN, and Why Does It Matter? ASN stands for Advanced Shipment Notification – an electronic notice you send to Amazon before your truck arrives at their warehouse. In Amazon Vendor Central, submitting an ASN means providing detailed data about your shipment: which purchase order it’s for, which items and quantities you’re sending, and crucially, which items are packed in which cartons. This can be done manually via Vendor Central’s interface or via an EDI 856 message from your system. The ASN allows Amazon’s receiving docks to match incoming goods against your advance report. If there’s no ASN (or it’s inaccurate), Amazon is far more likely to shortage claim the invoice – essentially saying “we didn’t receive everything you said you sent” – and charge you fines for non-compliance in labelling or late delivery. In fact, without a correct ASN, vendors run “the risk of getting shortage claimed quite extensively” along with other chargebacks, as Khoo warns. In other words, the ASN is your first line of defence to ensure you get paid in full for what you ship.

What’s Changing in ASN Version 2: Starting in mid-2024, Amazon rolled out new pallet-level reporting requirements for ASNs in North America and Europe. Under the old system, vendors needed to specify for each shipment the purchase order, each product and quantity, and which box each product was in. Now, Amazon also requires mapping each carton to a specific pallet (for palletised shipments) and labelling each pallet with a unique barcode(huntersinsights.com). In practical terms, if you ship 10 pallets of goods, your ASN must indicate exactly which cartons are stacked on pallet 1, pallet 2, and so on – and each pallet needs a scannable SSCC or AMZNCC barcode license plate label in addition to the carton labels(khoocommerce.com). This is a big step up in granularity. For less-than-truckload (LTL) or full truckload (FTL) freight, you can no longer just say “Shipment X has 5 pallets and 500 units” – you must detail pallet #1 contains cartons 1–50, pallet #2 contains cartons 51–100, etc.

“Amazon is rolling out ASN version 2 globally. Vendors now have to assign each carton to the relevant pallet, not just report total pallets. It’s more work on the warehouse floor.” — Christopher Khoo, Founder of KhooCommerce

Additionally, Amazon’s new ASN workflow in Vendor Central has been updated to collect pallet data (with an updated spreadsheet format for uploads) and, for EU vendors, to allow multiple tracking numbers for small parcel shipments (bringing EU into parity with the US)(huntersinsights.com). The effective dates were June 1, 2024, for UK/EU and July 1, 2024, for US/Canada(huntersinsights.com). Throughout July and August, Amazon has treated this as a “soft launch,” meaning vendors can opt in to ASN v2 or continue v1 temporarily, and Amazon has not yet been issuing chargebacks for non-compliance. However, that grace period is ending fast.

Deadlines and Enforcement: Amazon communicated that it expects full compliance with ASN v2 by mid-August 2024(huntersinsights.com). After that, failing to provide pallet-level details will likely trigger new chargeback fines. We don’t know the exact code yet, but Khoo anticipates a “pallet label non-compliance” charge similar to existing carton label fines – perhaps on the order of $5 per pallet missing a proper label, based on analogous fees. More importantly, Amazon will use these pallet details to streamline its receiving. If you ignore the new requirements, you face two hits: one from compliance fines, and another from increased shortage claims if Amazon’s warehouse can’t verify your shipment easily. In fact, industry watchers report that Amazon explicitly warned vendors that not adhering to the new standards by August will result in chargebacks(huntersinsights.com). It’s clear Amazon is serious about this change.

Key Points of ASN Version 2 Compliance: To summarise what vendors must do going forward:

• Include Pallet IDs and Labels: For each shipment, provide a pallet identifier for every box. Generate and affix a pallet label (SSCC / AMZNCC barcode) on each pallet in addition to carton barcodes(khoocommerce.com). The pallet label ties all cartons on that pallet to one code.
  
  
• Map Cartons to Pallets in the ASN: Whether you use EDI or manual upload, your ASN data file must list which pallet each carton is on(huntersinsights.com). In Vendor Central’s UI, that means adding pallet numbers and uploading the template spreadsheet with pallet information.
  
  
• Maintain Carton-Level Details: Carton-level ASN info (items and quantities per box) is still required. Each carton should have a scannable license-plate barcode. However, Amazon has slightly reduced redundant info on carton labels – for example, if you use a GS1-128 SSCC barcode, you no longer need to print the PO number and ship-to address on the carton label, since that’s encoded in the ASN data(khoocommerce.com). (For small parcel shipments, Amazon now insists on using an SSCC or Amazon-specific code on each carton; the older GTIN-14 “Goldlist” code alone is no longer sufficient for mixed SKU parcels(khoocommerce.com)).
  
  
• Label Every Pallet Clearly: Each pallet’s physical label should include the pallet SSCC/AMZNCC barcode and ideally human-readable info like the PO number, destination, and pallet sequence number (e.g. “Pallet 1 of 3”). Amazon’s guidelines indicate the pallet label may also need the Bill of Lading (BOL) or PRO freight number and total carton count on that pallet(khoocommerce.com). Make sure your warehouse or carrier doesn’t cover up these labels – they must be visible on arrival.
  
  

By embracing these changes, vendors enable Amazon’s distribution centres to receive inventory faster and with fewer errors. It’s a bit more work up front, but it pays off in smoother operations. As Khoo put it, Amazon is pushing this “to make the supply chain as smooth as possible” for both sides.

How These Changes Impact Vendors (and What To Do About It)

Operational Impact – More Granular Tracking: The most immediate burden of ASN v2 falls on warehouse and logistics teams. Capturing which carton goes on which pallet is a new step for many operations. Vendors who previously just stacked pallets and wrote “5 pallets, 500 units” now need a more detailed packing process. If you run an in-house warehouse, this likely means updating your WMS (Warehouse Management System) or procedures to record pallet composition during picking and packing. If you use a 3PL, you’ll need to coordinate with them to ensure they can produce the required ASN data and pallet labels. In short, expect slightly longer fulfillment lead times at first as teams adjust. It’s crucial to brief your warehouse staff or 3PL partners about the new Amazon requirements – they might not be aware unless you relay Amazon’s emails to them.

Cross-Team Communication: Implementing this change isn’t just a warehouse issue; it’s an organisation-wide concern. Finance teams care because missed requirements will incur chargeback fees and impact accounts receivable (through more disputes). Account managers care because late or defect-filled shipments hurt the vendor’s scorecard and relationship with Amazon. And obviously, operations teams are on the front lines of execution. Avoid silos: bring these teams together to assess current gaps and develop a plan. For example, finance can quantify how much money is at risk from non-compliance; operations can outline the process changes needed to comply; account managers can push for possible concessions (like negotiating a better freight allowance if your costs rise due to new processes). As Chris Khoo advises,

“it takes a joined-up conversation.”

The people feeling the pain (e.g. the finance director seeing chargeback deductions) must engage the people who can fix the root cause (the warehouse or 3PL managers).

Adapting Your Processes – Best Practices: To successfully navigate these changes, consider the following best practices for Amazon vendor compliance:

• Audit Your Current ASN Workflow: Map out how you currently generate ASNs. Do you do it manually via Vendor Central, or via EDI integration? Who is responsible for accuracy? With the new rules, you may need to update templates or EDI mappings. Ensure your systems can capture pallet IDs. If using Vendor Central’s UI, download the new ASN Excel template and train staff on the new fields.
  
  
• Upgrade Warehouse Systems if Needed: If your warehouse doesn’t already scan and log cartons to pallets, you might implement a simple barcode scanning step when building pallets. Many vendors are turning to software solutions (like KhooCommerce or similar ASN management tools) that can record carton-pallet info on the fly and automatically populate the ASN data. The investment in better inventory tracking will pay off by preventing mistakes.
  
  
• Label and Verify Pallets at Outbound: In addition to generating the proper labels, institute a double-check at loading: verify each pallet has the correct label and that all carton labels are readable and not covered. Some vendors have reported carriers occasionally re-labelling pallets or handling freight in ways that obscure labels – make it part of your SOP to ensure labels are secure and scannable (e.g. placed on multiple sides of the pallet).
  
  
• Monitor Amazon’s Feedback: Keep an eye on your Vendor Central chargeback reports and shortage claim reports in the months after implementing ASN v2. This will tell you if you’re doing it right. Ideally, you want to see zero “pallet label missing” chargebacks once they’re enforced. If you do see any, investigate immediately: was it a missed label, or did data not transmit correctly? Likewise, track your shortage claim rate – if it drops, your improved process is working (more on shortage claims below).
  
  

Remember that every vendor’s operations are unique. As Khoo noted,

“standards are standards, but the way they get implemented for your context will look different”

depending on factors like your number of warehouses, product types, etc. The goal is to incorporate Amazon’s requirements into your workflow as seamlessly as possible.

Optimising Vendor Performance Amid the Changes

Complying with Amazon’s logistics mandates isn’t just about avoiding penalties – it’s an opportunity to streamline your own operations and improve performance metrics. The most forward-thinking vendors are using this moment to revisit their entire supply chain and close efficiency gaps. Here are key strategy areas:

Preventing “Profit Leaks” from Shortages and Chargebacks: Vendor deductions like chargebacks and shortages can quietly erode 5–10% of your revenue – enough to turn a profitable account unprofitable(Stop Profit Leaks: How to Tackle Amazon Vendor Chargebacks). The new ASN process can help reduce these issues by ensuring Amazon receives exactly what they expect. But it’s not a silver bullet; you should concurrently tighten up other aspects of fulfillment. Make sure your invoices match shipments every time (short shipping Amazon but invoicing for full PO is a guaranteed shortage claim). Ensure OTIF (on-time, in-full) performance by confirming carrier pickups within Amazon’s requested window. Many chargebacks (e.g. for late delivery or missing box labels) act as signals of process weak points – treat them as a “real-time feedback mechanism” to improve, not just a cost of doing business(blog.inymbus.com). For example, if you get a “Label Missing” chargeback, find out why a box left without a proper barcode and fix that process.

Reducing and Managing Shortage Claims: Shortage claims deserve special attention because they often involve larger dollar amounts and are harder to recover. Amazon may deduct payments for months-old shipments, catching vendors off guard(Stop Profit Leaks: How to Tackle Amazon Vendor Chargebacks). The best strategy is prevention. Chris Khoo shared a success story where one company cut shortage claims by 90% after overhauling their warehouse processes. They implemented better labelling, rigorous outbound checks, and kept digital records of every shipment detail. The result was hundreds of thousands of dollars saved annually. The lesson: don’t be complacent or assume shortages are unavoidable. Examine your workflow for common root causes of shortages, such as:

• Short picking/short shipping: The warehouse didn’t actually send everything (due to stock errors or last-minute cuts), but the invoice wasn’t adjusted. Solution – implement checks to reconcile POs, pick lists, and ASNs so that if something can’t ship, the ASN/invoice is corrected preemptively.
  
  
• Mislabeled or mixed SKUs: Sending the wrong items or mixed cases when Amazon expected individual SKUs can lead to confusion in receiving. Solution – improve quality control on packing and use technology (like scanners) to validate carton contents.
  
  
• Carrier issues: Occasionally, labels fall off or freight gets misrouted, and Amazon receives goods without an ASN reference. While this is harder to control, working with reliable carriers and using Amazon’s preferred carriers when possible can mitigate risk. Also, keep all documentation (proof of delivery, etc.) so you can dispute if needed.
  
  

The new pallet ASN requirement will specifically help with scenarios where Amazon previously might have received pallets and not credited some cartons because they weren’t expecting them. By mapping cartons to pallets, you give Amazon fewer excuses to lose things. However, you should still monitor your remittances closely. Set up a weekly or monthly process to review Amazon payments against invoices. If shortage deductions occur, dispute them promptly – Amazon’s portal allows disputes typically up to 30–60 days after deduction, and beyond that, it gets tougher. Having the ASN data and pallet records on file will strengthen your case in disputes. As one expert noted in a related webinar, “every unit Amazon misplaced is your revenue sitting on a warehouse shelf – go get it!”(Stop Profit Leaks: How to Tackle Amazon Vendor Chargebacks). In many instances, vendors who audit and challenge shortages recover the majority of lost funds(Stop Profit Leaks: How to Tackle Amazon Vendor Chargebacks), so it’s worth the effort.

“We reduced one company’s shortage claims by 90% by improving their process. It shows you shouldn’t accept these costs as just the price of doing business – examine your operations and you can save a ton.” — Christopher Khoo

Leveraging Amazon’s Tools and Programs: Amazon is also rolling out tools that vendors can leverage to improve forecasting and inventory management. For example, Khoo mentioned a new Purchase Order Forecasting dashboard some vendors are testing. While forecasting isn’t directly related to ASN, it’s part of the larger logistics puzzle – better demand predictions can help you plan inventory and avoid last-minute rush shipments that lead to mistakes. If you have access to Amazon’s forecasting beta, use it to align your stock levels so you can fulfill POs smoothly. Additionally, Amazon has been encouraging participation in programs like Dedicated Fulfillment (consignment-like arrangements) or specialised pallet programs in certain regions. Evaluate if those programs make sense for your business; sometimes Amazon offers incentives (like relaxed chargebacks or co-op terms) if you participate in certain supply chain initiatives.

Continuous Improvement Mindset: Ultimately, staying successful on Amazon’s vendor platform requires a mindset of continuous improvement. Amazon will undoubtedly introduce more changes down the line – today it’s pallet ASNs, tomorrow it might be new packaging guidelines or AI-based ordering systems. The vendors who thrive are those who “have a good focus on P&L and underneath processes, not just top-line sales”. Regularly review your performance metrics: on-time delivery rates, fill rates, chargeback amounts, shortage dollars, warehouse cycle times, etc. If something is trending poorly, dig in to find out why and fix it proactively. Also, foster internal dialogues: as Khoo suggests, periodically ask your team “Should we be spending hundreds of thousands each year on these defects and manual reconciliations, or can we improve this?”. This kind of challenge can spark projects that save money and headaches.

In summary, the logistics changes are a wake-up call to upgrade your operational excellence. They may require an initial scramble, but they push you toward best practices that will benefit your business beyond just Amazon. By embracing better tracking, tighter compliance, and cross-team collaboration, you turn what could be a compliance burden into a competitive advantage – running a leaner, smarter Amazon vendor operation than your peers.

Conclusion: Stay Ahead of Amazon’s Curve (And Your Competition)
