Regulatory Technical Brief: Amazon FBA FNSKU Thermal Label Sizes (Dymo 30334, Zebra 2×1, Rollo 4×6 & Avery 5160)

Amazon FBA Seller Central defaults to multi-up PDF sheets that do not fit single-roll direct thermal printers like Dymo 450/550 or Rollo without manual cropping. Our studio exports exact single-label vectors scaled to your thermal roll size.

  • Direct presets for Dymo 30334 (2.25" × 1.25"), Zebra (2" × 1"), Combined Compliance (3" × 2"), and Rollo (4" × 6").
  • Maintains Amazon's mandatory 0.25-inch horizontal and 0.125-inch vertical quiet zones.
  • Zero pixelation: pure SVG vector bars ensure instant scanner reads at Amazon FBA receiving docks.

Frequently Asked Regulatory Questions (FDA / OEHHA / CPSC)

Why should I cover the UPC/EAN barcode with an FNSKU label?

Unless you are using manufacturer barcode commingling, Amazon requires every unit to have a single visible scannable barcode—your unique FNSKU (`X00...`)—and requires covering any existing GS1 UPC/EAN barcode so scanners do not misread it.

Can I use thermal transfer or direct thermal labels for Amazon FBA?

Both work, provided the label remains scannable for at least 24 months under warehouse lighting and temperature conditions.
