Time: Jul 05,2025 Author: SFC Source: www.sendfromchina.com

Incorrect labeling can lead to significant setbacks in your Amazon FBA operations, including inventory mishandling and shipment delays. Understanding and adhering to Amazon's labeling requirements is essential for smooth fulfillment. This article provides a detailed overview of FBA labeling standards, highlights common mistakes, and offers best practices to ensure compliance and efficiency.

1. What Are Amazon’s Labeling Requirements

Amazon mandates that each product unit sent to its fulfillment centers be labeled with a scannable barcode. This barcode can be either:

- Manufacturer Barcode: Such as UPC, EAN, or ISBN.
- Amazon Barcode (FNSKU): A unique identifier assigned by Amazon to track products within its network.

Sellers must ensure that:

- Each unit has a unique FNSKU corresponding to its specific variation (e.g., size or color).
- The barcode is easily accessible and scannable.
- Any existing scannable barcodes on the product are removed, covered, or rendered unscannable.

Failure to comply can result in inventory being refused, returned, or repackaged at the seller's expense.

2. Types of Amazon’s Labels

Amazon's Fulfillment by Amazon (FBA) program relies heavily on accurate labeling to ensure efficient inventory management and order fulfillment. Understanding the different types of labels used within the FBA ecosystem is crucial for sellers aiming to maintain compliance and streamline operations. Below, we delve into the primary label types, their purposes, and best practices for their application.

FNSKU Labels (Fulfillment Network Stock Keeping Unit)

The FNSKU is Amazon's unique identifier for products stored and shipped through its fulfillment centers. Each FNSKU is exclusive to a seller and a specific product, ensuring that inventory is accurately tracked and attributed.

Key Features
- Unique Identification: Links a product to the specific seller, preventing commingling with identical products from other sellers.
- Essential for FBA: Required for products that are not eligible for manufacturer barcode tracking.
- Label Requirements: Must include the scannable barcode, product title, and condition (e.g., new, used).

Best Practices
- Print labels using a laser printer at 300 DPI resolution on white, non-reflective adhesive paper.
- Ensure labels are between 1" x 2" and 2" x 3" in size.
- Place labels on a flat surface of the product packaging, avoiding edges and corners.
- Cover any existing barcodes to prevent scanning errors.

Note: For products requiring additional packaging (e.g., polybags), affix the FNSKU label on the outermost layer to ensure scannability.

Manufacturer Barcodes (UPC, EAN, JAN, ISBN)

Manufacturer barcodes are standard identifiers assigned by product manufacturers and are commonly found on retail products. Amazon allows the use of these barcodes under specific conditions.

Types
- UPC (Universal Product Code): 12-digit codes used primarily in North America.
- EAN (European Article Number): 13-digit codes used internationally.
- JAN (Japanese Article Number): Similar to EAN, used in Japan.
- ISBN (International Standard Book Number): 10 or 13-digit codes used for books.

Usage Considerations
- Sellers can opt to use manufacturer barcodes if they enroll in Amazon's stickerless, commingled inventory program.
- In this program, products from multiple sellers are pooled together, and Amazon fulfills orders based on the nearest available inventory.
- While this can streamline operations, it may lead to issues if other sellers' products are counterfeit or of lower quality.

Best Practices
- Ensure that the manufacturer barcode is scannable and not obstructed.
- If choosing to use manufacturer barcodes, monitor customer feedback closely to detect any issues arising from commingled inventory.

Transparency Labels

Transparency is Amazon's product serialization service designed to prevent counterfeit products from reaching customers. Brands enrolled in the Transparency program apply unique, secure codes to each unit of their products.

Key Features
- Unique Codes: Each product unit receives a unique Transparency code that can be scanned to verify authenticity.
- Brand Protection: Helps protect brand reputation by ensuring only genuine products are delivered to customers.
- Customer Trust: Customers can scan Transparency codes using the Amazon app to confirm product authenticity.

Implementation
- Brands must enroll in the Transparency program through Amazon.
- Once enrolled, apply Transparency labels to each unit before shipping to Amazon fulfillment centers.
- Ensure that Transparency labels are not covered by other labels and are placed on a flat, visible surface.

Shipping Labels (FBA Box ID Labels)

Shipping labels, also known as FBA Box ID labels, are essential for the transportation and receipt of inventory at Amazon fulfillment centers. These labels provide information about the shipment and help Amazon associate boxes with the correct shipment plan.

Key Features
- Shipment Identification: Includes shipment ID and destination fulfillment center information.
- Tracking: Facilitates tracking of shipments from the seller to Amazon's warehouses.
- Compliance: Required for all boxes shipped to Amazon fulfillment centers.

Best Practices
- Print shipping labels using a thermal printer for durability.

6. Common Mistakes in Labeling Amazon FBA Labels

Proper labeling is crucial for the smooth operation of your Amazon FBA business. Mistakes in labeling can lead to delays, additional fees, or even account suspension. Understanding and avoiding these common errors ensures that your products are processed efficiently and reach customers without issues.

Incorrect or Missing FNSKU Labels

Each product unit sent to Amazon's fulfillment centers must have a unique FNSKU (Fulfillment Network Stock Keeping Unit) label. Failing to apply the correct FNSKU or omitting it entirely can result in inventory being rejected or misrouted. Ensure that:
