What Are Amazon FBA Labels?
Amazon FBA labels are adhesive stickers that uniquely identify your products within Amazon's fulfilment network, ensuring they are correctly received, stored, and dispatched to customers. They contain vital information such as barcodes, product identifiers, and sometimes specific handling instructions, acting as your product's passport into the FBA system.
- Labels identify products for Amazon's FBA system.
- They ensure accurate receiving and fulfilment.
- Correct labelling prevents delays and fees.
- Two main types exist: Product Labels and Shipping Labels.
When you send products to Amazon's fulfilment centres, each item needs to be identifiable. This is where Amazon FBA labels come into play. They are not merely for decoration; they are a critical part of the logistical chain that allows Amazon to manage millions of products from thousands of sellers efficiently. Without the correct labels, your inventory could be refused, delayed, or incur unexpected fees, directly impacting your sales and customer satisfaction. Understanding the requirements for these labels is a foundational step for any seller utilising the FBA service, especially when considering selling on Amazon UK or any other Amazon marketplace.
The Importance of Accurate Labelling
The primary purpose of FBA labels is to link a specific unit of your product to your Amazon seller account. Amazon uses these labels to track inventory movement, manage stock levels, and pick and pack orders accurately. If a label is missing, damaged, or incorrect, Amazon fulfilment centre staff cannot identify the item, leading to potential issues like:
- Receiving Delays: Your inventory might be held up or rejected if it cannot be scanned.
- Storage Issues: Products may be placed in the wrong bin or location, making them difficult to find.
- Customer Order Errors: The wrong item could be sent to a customer, leading to returns and negative reviews.
- Additional Fees: Amazon often charges fees for labelling items themselves if they are not pre-labelled correctly.
For sellers looking at how to sell books online on Amazon or any other product category, adhering to these labelling standards is non-negotiable. The specific requirements can vary slightly depending on the product type and its condition, but the core principle remains the same: clear, scannable, and accurate identification.
Product Labels vs. Shipping Labels
It's vital to distinguish between two primary types of labels involved in the FBA process: product labels and shipping labels. While both are essential, they serve different purposes and are applied at different stages.
Product Labels (FNSKU or UPC/EAN)
These labels are affixed directly to the individual product unit. They contain the barcode that Amazon scans upon receiving your inventory. The most common types are the FBA SKU (FNSKU) and Universal Product Codes (UPCs) or European Article Numbers (EANs).
Shipping Labels
These are applied to the outer cartons or pallets containing multiple units of your products. They contain Amazon's carrier information, tracking details, and a reference to the shipment plan. These labels ensure that your consolidated shipments reach the correct Amazon fulfilment centre and are processed as part of your planned inventory shipment.
Navigating these distinctions is key to a streamlined FBA operation. Understanding which label goes where and when is the first hurdle for many new sellers.
Understanding FBA Product Identifier Labels
Product identifiers are the barcodes that allow Amazon to track individual items within its vast fulfilment network. For FBA, the crucial identifier is typically the FBA SKU (FNSKU), a unique barcode generated by Amazon. Alternatively, you can sometimes use existing UPC or EAN barcodes if your product is not bundled or private label.
The Role of the FNSKU
The FBA SKU (Fulfillment Network Stock Keeping Unit), often referred to as FNSKU, is a scannable barcode label that Amazon assigns to your product ASIN (Amazon Standard Identification Number) within your seller account. When you list a product for FBA, Amazon provides you with the FNSKU label. This label is unique to you and your product, even if the product is also sold by other sellers. Using FNSKUs prevents commingling of inventory, ensuring that only your specific units are tracked and fulfilled for your orders. This is particularly important for private label sellers or when selling identical items from different suppliers.
You can generate and print FNSKU labels directly from your Seller Central account. Amazon also offers a labelling service for a fee if you prefer them to handle it.
Using UPC/EAN Codes
If your product already has a manufacturer-applied UPC (Universal Product Code) or EAN (European Article Number) barcode, and you are not selling a private label product, you might be able to use these instead of FNSKUs. However, this comes with a significant caveat: it enables 'commingled inventory'. This means Amazon will treat all units of that ASIN with the same UPC/EAN, regardless of the seller, as interchangeable. While this can seem simpler, it carries risks. For example, if another seller sends in lower-quality or counterfeit versions of the same product under the same UPC, your customers might receive those instead of yours. It is generally recommended, especially for new sellers or those with branded products, to opt for FNSKUs to maintain control and traceability of your specific inventory.
Before deciding, always check Amazon's current policies in Seller Central regarding which barcode is mandatory for your product category. For instance, when learning how to sell books online on Amazon, using the ISBN (a type of EAN) is common, but FNSKUs might still be preferred for certain scenarios.
Label Requirements for Bundles and Custom Products
If you are selling a bundle of multiple items sold as a single unit, or a custom product, you must apply an FNSKU label. These labels clearly identify the bundle as a distinct ASIN. Ensure the bundle itself is properly packaged and sealed so that the FNSKU is the only barcode visible or accessible for scanning. Similarly, any product that requires additional preparation, such as requiring bubble wrap, or is a 'set' that isn't pre-bundled by the manufacturer, will need an FNSKU.
This ensures that Amazon's fulfilment process correctly identifies and handles these unique offerings, preventing errors in order fulfilment.
Printing Your Amazon FBA Labels
Accurate printing is as vital as choosing the correct label type. Using the right materials and printer settings ensures your FBA labels are scannable, durable, and meet Amazon's specifications, thereby avoiding costly rejections or fees.
Choosing the Right Label Material and Printer
For FBA product labels (FNSKU or UPC/EAN), you will need labels that are durable and will not peel or tear easily. Amazon recommends using standard white, non-glossy paper labels. Avoid labels that are too shiny, as glare can interfere with scanning. Similarly, do not use labels that are too thin or transparent. The labels must be fully opaque.
Printer Type: The most common and recommended printers for FBA labels are thermal transfer or direct thermal printers. These are ideal because they produce crisp, dark, and durable prints that are highly scannable. While inkjet or laser printers can be used, they may not offer the same level of print quality and durability, especially if the labels are exposed to moisture or friction. Ensure your chosen printer can handle the label sheet sizes you intend to use.
Label Sheets: You can purchase blank label sheets online or from office supply stores. Common sizes for FBA product labels are 30 labels per sheet (e.g., 10 rows x 3 columns) or 24 labels per sheet. Ensure the label dimensions are compatible with the templates available in Seller Central or your chosen label printing software. For shipping labels, Amazon typically requires 6" x 4" thermal labels.
Always perform a test print on a plain piece of paper first to check alignment and print quality before committing to printing on your actual label sheets.
Generating and Printing Labels from Seller Central
Amazon Seller Central provides tools for generating and printing both FNSKU labels and shipping labels. For product labels:
- Navigate to your Inventory page in Seller Central.
- Select the product(s) you wish to label.
- From the 'Action on selected' dropdown menu, choose 'Print item labels'.
- Select the number of labels needed per item.
- Choose the label sheet size that matches your purchased labels.
- Amazon will generate a PDF document containing your labels. Download and print this document using your chosen printer.
For shipping labels, you will generate these as part of the shipping plan creation process when you are ready to send inventory to Amazon. This involves confirming quantities, carrier selection, and dimensions, after which Amazon provides printable shipping labels.
When to Use Amazon's Labelling Service
If you prefer not to handle the printing and application of FBA labels yourself, Amazon offers a labelling service through Seller Central for a fee per item. This is a convenient option, especially for sellers who are new to FBA or those who want to save time. Amazon will apply the required FNSKU labels to your products when they arrive at the fulfilment centre.
Trade-offs: While convenient, Amazon's labelling service incurs a cost, which can add up, particularly for lower-priced items. It also means your products will be handled by Amazon before they are placed into your sellable inventory, potentially adding a slight delay. For sellers looking to understand how to sell used books on Amazon or other items where condition might be a factor, using your own labelling can provide an extra layer of quality control.
The decision often hinges on your product's cost, your profit margins, and your available time and resources.
Applying FBA Labels Correctly
The physical application of FBA labels is as crucial as their content and print quality. Incorrect placement can render a label unscannable, leading to the same issues as a missing or damaged label.
Placement Guidelines for Product Labels
FBA product labels (FNSKU or UPC/EAN) must be applied directly to the product unit. Ensure the label is placed on a flat surface where it will not easily peel off or get damaged during transit or storage. Avoid placing labels over seams, edges, or curves, as this can cause the label to lift or become distorted, making it unreadable by scanners.
Key Placement Rules:
- Single Label: Only one scannable barcode should be visible and accessible on the product. If the product already has a barcode (like a manufacturer's UPC), you must cover it completely with your FNSKU label.
- Clear and Accessible: The label must be fully visible and easily scannable. Do not place it on the bottom of a product if that surface is likely to be the last thing handled by a picker.
- Secure Application: Use strong adhesive labels that will not fall off. Ensure the entire label is adhered smoothly to the product surface.
- No Overlapping: Do not overlap labels, as this can create false readings or make scanning impossible.
For items that are sold in multiples (e.g., a pack of 10 pens), the label should be applied to the outer packaging of the pack, not to each individual pen, unless each pen is intended to be sold separately.
Packaging Requirements for FBA Products
Beyond labels, how your product is packaged significantly impacts its readiness for FBA. Many items require additional packaging to protect them during transit and storage, and to ensure they can be labelled appropriately.
- Poly Bags: If using poly bags, ensure they are clear and have a suffocation warning label if the opening width is 5 inches or larger. The FBA product label should be affixed to the outside of the bag.
- Bubble Wrap: Items that are fragile or could be damaged by crushing must be encased in bubble wrap. The FBA product label should be applied over the bubble wrap, ensuring it lies flat and is secure.
- Shrink Wrap: Similar to poly bags, shrink-wrapped items must have the label applied to the outside of the wrap.
- Boxes: Products sold in their own box (e.g., shoe boxes, electronics boxes) usually require an additional layer of protection. Amazon recommends either placing the product box inside a poly bag or encasing it in bubble wrap, then applying the FNSKU label. Alternatively, you might use a 'box-in-box' method.
Always refer to Amazon's FBA packaging and prep requirements in Seller Central. For example, if you are learning how to sell on Amazon UK, these guidelines are consistent across marketplaces but checking local nuances is wise.
Ensure any existing barcodes on the product are completely covered by your FBA label if you are using FNSKUs, or that the FBA label is placed adjacent to, but not covering, the original barcode if using UPC/EANs and Amazon's policy allows.
Handling Oversized and Heavy Items
Products that exceed certain dimensions or weight limits may have additional labelling requirements, such as 'Ready to Ship' labels, indicating that no further packaging is needed beyond the manufacturer's shipping container. These items also have specific handling fees and storage considerations.
It is essential to know your product's dimensions and weight and compare them against Amazon's FBA size tiers to ensure compliance. Incorrectly labelled or packaged oversized items can incur significant penalties.
Common FBA Labelling Mistakes and How to Avoid Them
Even with careful planning, FBA sellers can fall into common labelling traps. Identifying these pitfalls beforehand is crucial for maintaining a smooth inventory flow and avoiding unnecessary expenses.
Ignoring Amazon's Specific Requirements
Amazon's FBA labelling guidelines are detailed and can change. A common mistake is relying on outdated information or assuming generic labelling practices will suffice. For instance, using glossy labels, not covering existing barcodes, or misinterpreting when an FNSKU is mandatory over a UPC/EAN can lead to immediate problems. Always consult the latest FBA labelling policies within your Amazon Seller Central account. This is especially true when considering complex products or new selling ventures like how do you sell on Amazon UK for the first time.
Solution: Regularly check the 'Fulfillment by Amazon' section in Seller Central for updates on packaging, labelling, and prep requirements. Bookmark the relevant pages for quick reference.
Incorrect Barcode Scanning
Labels must be scannable. This means they need to be printed clearly, with sufficient contrast, and at a high enough resolution. Smudged ink, faint printing, or low-quality label stock can render a barcode unreadable. Similarly, if a label is placed over a curve or seam, or if it's damaged, scanners will struggle.
Solution: Use a high-quality printer (ideally thermal). Print a test page and scan the barcodes using a smartphone app or handheld scanner to verify readability before printing in bulk. Ensure labels are applied flat and securely.
Mishandling Bundles and Sets
Selling multiple items as one unit (a bundle) requires careful labelling. If each item within the bundle has its own barcode, and you only label the outside of the bundle, Amazon's system might get confused. It's crucial that the FNSKU clearly identifies the bundle as a single sellable unit.
Solution: For bundles, always use an FNSKU label that corresponds to the unique ASIN you've created for that bundle. Ensure this label covers any individual item barcodes within the bundle, and that the bundle is securely packaged so it cannot be opened inadvertently.
Failure to Cover Existing Barcodes
If you are using FNSKUs, they must completely obscure any pre-existing manufacturer barcodes (like UPCs or EANs) on the product. If both barcodes are visible and scannable, Amazon's system might scan the wrong one, leading to inventory errors.
Solution: Ensure your FNSKU label is large enough to cover the entire original barcode. If it doesn't, you may need to use a larger label or consider Amazon's labelling service, or a different packaging approach to ensure full coverage.
Ignoring Shipping Label Requirements
Beyond product labels, the outer cartons sent to Amazon require specific shipping labels. These are generated from your shipping plan in Seller Central and contain routing information for Amazon's logistics network. Using incorrect or missing shipping labels can result in your shipment being rejected or incurring re-handling fees.
Solution: Always print shipping labels directly from your Amazon shipping plan. Ensure they are printed clearly and affixed to the largest side of the carton, away from any seams or edges. Each carton should have its own unique shipping label.
Accurate FBA labelling is not just a compliance step; it's a fundamental component of efficient inventory management and customer satisfaction.
By proactively addressing these common mistakes, sellers can significantly improve their FBA operational efficiency and avoid costly compliance issues.
Alternatives and Related FBA Considerations
While Amazon FBA labels are a specific requirement, exploring alternatives and related considerations can offer a more comprehensive understanding of managing inventory and fulfilling orders effectively.
FBA Prep Services
For sellers who find the labelling and preparation process too time-consuming or complex, using third-party FBA prep centres is a viable alternative. These services specialise in receiving your inventory, applying FBA labels, packaging items according to Amazon's standards, and then shipping them to Amazon fulfilment centres on your behalf. This can be a significant time-saver, allowing you to focus on sourcing products and marketing.
When to use:
- You lack the time or space for prep work.
- Your products require specialised preparation (e.g., fragile items, specific bundles).
- You want to streamline your FBA workflow and reduce manual handling.
When selecting a prep centre, ensure they are familiar with Amazon's FBA requirements and have a reliable system for tracking inventory and communicating with sellers. This is a popular choice for sellers of all sizes, from those just learning how to sell books online on Amazon to large-scale operations.
Using Fulfilment By Merchant (FBM)
An alternative to FBA altogether is Fulfilment By Merchant (FBM). With FBM, you store your own inventory and are responsible for picking, packing, and shipping each order directly to the customer. This gives you complete control over your inventory and fulfilment process, and you avoid FBA fees. However, it also means you handle all the logistics yourself, which can be demanding as sales volume grows.
Consider FBM if:
- Your products are very large, heavy, or have unusual storage requirements.
- You want to maintain direct control over shipping and packaging quality.
- You are concerned about FBA fees or inventory commingling.
While FBM avoids FBA labelling, you still need clear shipping labels for your customer orders, and you must adhere to Amazon's shipping standards to maintain your seller performance metrics. For some businesses, dropshipping Amazon UK might be a variant of FBM they explore, where a third party ships directly to the customer from their own stock.
Understanding Amazon Selling Fees
Whether you use FBA or FBM, understanding Amazon selling fees is crucial for profitability. FBA sellers incur fulfilment fees (which cover picking, packing, and shipping) and storage fees (monthly and long-term). There are also referral fees for most product categories. FBM sellers primarily pay referral fees and potentially fulfilment costs from their chosen carriers.
Key fees to consider:
- Referral Fees (percentage of sale price).
- FBA Fulfilment Fees (per unit, based on size and weight).
- FBA Monthly Inventory Storage Fees.
- Optional FBA services (e.g., labelling, prep).
Accurate labelling can help avoid unexpected fees associated with incorrect inventory handling or Amazon performing the labelling service for you. Always review the most current fee structure in Seller Central.
Closing an Amazon Seller Account
In rare cases, sellers might consider closing their Amazon seller account. This is a significant decision, usually made if the business model changes or if selling on Amazon is no longer viable. Before closing, it is imperative to:
- Sell off all existing inventory.
- Cancel any FBA shipments that have not yet been processed.
- Ensure all customer orders are fulfilled and returns are managed.
- Resolve any outstanding fees or charges.
The process of closing an account is detailed in Seller Central, and it's important to follow the steps precisely to ensure a clean break and avoid future complications.
While not directly related to labelling, these broader considerations form part of the complete picture for any Amazon seller.
