Proper prep and labeling are non-negotiable when shipping to Amazon FBA. Mistakes can result in delays, added fees, or even rejected shipments. At SnappyCrate, we specialize in FBA-compliant prep to keep your products moving smoothly into Amazon fulfillment centers.

Here’s your step-by-step guide to preparing and labeling products like a pro.

🔑 1. Understand Amazon’s Prep Requirements

Amazon requires every unit to be securely prepped to prevent damage and ensure scannability. Common prep types include:

  • Poly bagging: For loose items, fabric goods, or items that could leak.
  • Bubble wrapping: For fragile or breakable items.
  • Taping: Seal all openings on retail boxes.
  • Kitting/Bundling: Multi-item packs must be labeled as “Sold as Set.”

âś… SnappyCrate handles all prep types, ensuring compliance every time.

🖨️ 2. Print and Apply FNSKU Labels Correctly

Each unit must be labeled with an Amazon FNSKU barcode:

  • Labels must be scannable and placed on a flat, visible surface.
  • Cover all manufacturer UPCs to avoid scanning errors.
  • Use white, non-reflective labels (1″ x 2″ standard size).

đź’ˇ Pro Tip: Print labels directly from Seller Central or let SnappyCrate handle printing and application for you.

📦 3. Follow Box Content and Carton Labeling Rules

Every shipment must include box-level details:

  • Provide box content information in Seller Central or use 2D barcodes.
  • Each carton must have Amazon shipment ID labels on two adjacent sides.
  • Avoid damaged or reused boxes that compromise label visibility.

âś… We apply both unit and carton labels in-house, using Amazon-approved printers.

🪵 4. Prep for Specialty Products

Certain products need extra care:

  • Liquids: Double-sealed and bagged to prevent leaks.
  • Sharp items: Must be sheathed or bubble-wrapped.
  • Apparel/fabric: Poly bags with suffocation warnings.
  • Hazmat (dangerous goods): Special paperwork and labeling required.

âś… SnappyCrate is trained in Hazmat compliance and advanced prep.
