Stock RFID Labels: Sizes, Inlays, and Walmart-Compliant Rolls

CiS Technical TeamJune 10, 20269 min read

Last verified: June 2026

In short: CIS stocks both general-purpose and Walmart ARC-certified RFID labels in popular 4×6 and 2.13×1.34 sizes, ready to encode on Zebra, TSC Printronix, and Datamax printers and ship the same day.

Watch: RFID Label Capabilities

How CIS builds RAIN RFID (UHF Class 1 Gen 2) labels and tags, from inlay selection through encoding and verification, for manufacturing, distribution, retail, and asset tracking.

  • RFID inlays are embedded between the facestock and liner, so the label prints and applies like any other pressure-sensitive label.
  • Inlay choice depends on read range, substrate (metal, liquid, cardboard), and the environment the tag lives in.
  • RAIN RFID needs no line of sight, reads at distance, and reads many tags at once.
  • CIS checks inlay compatibility against your printer/encoder and your customer specification before production.
  • Available as stock or fully custom printed RFID labels.

Country Innovation & Supply stocks UHF (RAIN RFID) thermal transfer labels for immediate shipment, including the two ARC-certified sizes most commonly used to meet the Walmart RFID supplier mandate. This page lists every stock RFID part number, the inlay and chip family in each construction, ARC certification status, and the printers that encode them.

RFID Labels in 30 Seconds

An RFID label is a standard thermal transfer label with a thin UHF transponder, a microchip and printed antenna ("inlay"), laminated between the face stock and release liner. A reader powers the chip wirelessly and reads its EPC (Electronic Product Code) memory at a distance, with no line of sight required.

Compared to barcode-only labels, RFID adds:

  • No line of sight, read through cartons, totes, and pallet wrap
  • Bulk reads, hundreds of tags per second from a single antenna pass
  • Item-level serialization, every unit has a unique EPC
  • Re-writable memory, encode at the point of application, update downstream

CIS RFID stock uses EPC Class 1 Gen 2 UHF inlays with 128 bits of EPC memory, the standard for retail mandates, logistics, asset tracking, and supply-chain visibility.

Walmart RFID Stock Rolls, ARC-Certified

The two sizes below are the workhorse SKUs used by Walmart-mandate suppliers in apparel, home goods, consumer electronics, toys, sporting goods, and the other categories Walmart has rolled the RFID program into. Both ship from Chicago and are stocked specifically for in-line print-and-encode at the supplier.

Auburn ARC submission

Walmart requires RFID tags to be validated by the Auburn University RFID Lab before mass production. CIS can supply 10–15 printed and encoded samples for ARC submittal as part of any new program.

Selecting the Right Inlay

If you need to read…Choose
Standard cartons, totes, apparel on hangersEOS 430 / M830, broad ARC coverage, best general-purpose UHF inlay
Small retail items (jewelry, cosmetics, accessories)EOS 241 / M830, smaller footprint, fits 1.73" x 0.71" tags
Items in dense, mixed-SKU bins (apparel hangtags)EOS 300 U9, high read sensitivity in crowded reads
Metal or liquid-adjacent assetsOn-metal / liquid-tolerant inlay (custom), quote required
For custom inlay/face-stock combinations, on-metal hard tags, polyester face stocks for harsh environments, color floodcoats, encoded-and-serialized rolls, see Industrial Labels and request a quote.

Printer Compatibility

CIS stock RFID rolls are compatible with the entire TSC Printronix Auto ID printer series and most industry-standard UHF RFID printers, including:

Printer FamilyModels that encode UHF RFID
Zebra industrialZT411R, ZT421R, ZT231R, ZT610R, R110Xi4, RZ400/RZ600
Zebra desktopZD500R, ZD621R
TSC PrintronixT8000R, T6000e RFID, MH241T-RFID, ML240P-RFID
HoneywellPM45 RFID, PM43 RFID, PD45S RFID
SATOCL4NX Plus RFID, CL6NX Plus RFID
For ribbon selection paired with these printers, see the Ribbons Resource Center and the Thermal Transfer Ribbons reference. RFID paper face stock prints cleanly with Premium Wax or General Purpose Wax ribbons in most applications; durable program tags on synthetic face stock should pair with Premium Wax/Resin.

Ribbon Pairing for Stock RFID

RFID Stock Part FamilyFace StockRecommended Ribbon
RFTT400xxx (4" x 2", 4" x 6")Thermal transfer paperPremium Wax (default), General Purpose Wax

How to Order

  • Confirm your printer family and the encoder model, encoding requires an RFID-capable printer, not just any thermal printer.
  • For Walmart-mandate programs, pick the ARC-certified size that matches your item type and submit Auburn samples before production.
  • Match a part number from the tables above.
  • Request a quote with the part number, case quantity, and whether you need a CIS service-bureau print-and-encode run.

Stocking, Shipping & Returns

  • Same-day shipping on stock RFID rolls when orders are received by 2 p.m. local time at the Chicago warehouse.
  • Service-bureau print-and-encode is available, encoded RFID labels ship 3–5 business days after proof approval.
  • 0% unders, RFID orders do not include rejects in the final label count.
  • All RFID sales are final. Returns/refunds are issued only for documented quality issues; inspect every shipment on arrival. If you are unsure which RFID construction you need, contact the CIS RFID team before placing the order.

Compliance & Standards

  • EPC Class 1 Gen 2 UHF, global RAIN RFID standard; all CIS stock RFID complies
  • 128-bit EPC memory on every stock inlay
  • Auburn ARC certification, RFTT213134 and RFTT173071 carry ARC F/I/L/O/Q/R/Y2/W5/W6 (varies by SKU)
  • Walmart RFID Supplier Mandate, apparel, home, consumer electronics, toys, sporting goods, auto care
  • GS1 EPC encoding supported by CIS service-bureau encoding

Frequently Asked Questions

What's the difference between RFID and barcode labels?

RFID reads through cartons, reads hundreds of tags at once, and doesn't require line of sight. Barcodes are cheaper per label and read one at a time, in line of sight. Many CIS customers run both on the same label.

Do I need ARC certification for non-Walmart programs?

No, ARC is required only for Walmart's mandate. Other retail and supply-chain programs use EPC Class 1 Gen 2 without ARC validation.

Why are my encoded labels failing at the reader?

Most often: chip-position miscalibration, reader power, or a damaged ribbon. See the RFID Calibration & Troubleshooting FAQ.

Can mobile printers encode RFID reliably?

Yes, but only with certified mobile RFID media and a fully charged battery. CIS 1" core / 5" OD rolls are designed for fixed printers; request a custom quote for mobile-printer stock.

How do I get Auburn ARC samples?

CIS supplies 10–15 printed-and-encoded sample tags for ARC submittal as part of any new Walmart program. Talk to a specialist to start.

Can you pre-encode rolls before shipment?

Yes, service-bureau encoding ships 3–5 business days after proof approval. Encoded RFID sales are final.

Next Steps

  • Request a Quote, stock part #, case quantity, or custom build
  • Talk to a Specialist, for Walmart ARC, inlay selection, or encoding help
  • Don't see your inlay? Custom on-metal, liquid-tolerant, and synthetic constructions available on quote.
