Fulfillment by Amazon (FBA) is a service where Amazon stores your products in their fulfillment centers and they pick, pack and ship your orders to your customers on your behalf. Most times, they will handle your customer refunds too. FBA is made to save you the hassle of warehousing and shipping your products on Amazon.

Assumption: You’re selling your FBA products to USA and Canada.

Step 1: Packing for fulfillment centers

Packing: Do’s & Don’ts

✓ Boxed items: Include stuffing to keep your items secured and free from damages during shipping.

✓ Stuffing materials allowed: Crushed paper, bubble wrap, foam, and air pillows.

× Stuffing materials not allowed: Styrofoam peanuts, shredded paper, crinkle wrap, biodegradable or corn-starch packing peanuts.

× No loose items: Pack multiple pieces (sold as one unit) all into one poly bag. (For example, if wheels and handles are sold as one piece, bagging them into one packaging instead of separately)

Step 2: Barcode Labeling

Every FBA item fulfilled by Amazon requires a barcode label for tracking purpose. The label will include a product name, product condition, FNSKU number and barcode. There are three ways to get your product barcodes.

  1.  Manufacturer barcode
  2. FBA Label service (usually comes at US$0.20 cost per label)
  3. Self-printing of FBA barcode using Amazon’s online tools

✓ Stick labels on flat and smooth surfaces

× Do not place labels at corners, curves, folded edges, box seal openers

× Avoid using smudge, faded or torn labels

× Avoid using inkjet printers which are prone to ink-smearing

Step 3: Shipping to fulfillment centers

Saving Tip: Start slow, especially if you’re new to FBA. There will inevitably be new things you learn, like what your annual inventory turnover is. You’ll find out that Amazon charges a long-term storage fee for inventory stored for more than 6 months in their fulfillment centers. This long term fee is in addition to the monthly inventory fee (which are more expensive between October and December). So you should prepare less shipment for months with low sales.
