Labeling, Barcodes & Packaging for US Retail (2026)
The cheapest place to make a Thai-made product retail-ready is the Thai factory. Repacking in a US warehouse costs USD 0.35–1.20 per unit; doing it in production costs cents. This is the spec pack to hand your supplier before the first PO.
Consumer-unit labeling checklist
| Element | Rule of thumb |
|---|---|
| Country of origin | "Made in Thailand", conspicuous, permanent, in English |
| Identity of product | Common or usual name on the principal display panel |
| Net contents | US customary + metric |
| Responsible party | US importer or distributor name and full address |
| Care/fiber (textiles) | FTC Care Labeling Rule + Textile Fiber Products Identification Act |
| Warnings | CPSC or Prop 65 language where applicable |
Barcodes: get GS1 right the first time
- Buy prefixes from GS1 US directly — resold single UPCs are rejected by most national retailers.
- Assign a distinct GTIN-12 (UPC-A) per sellable variant: colour, size, count.
- Use ITF-14 on the master carton for the case GTIN, printed at the correct magnification with a bearer bar.
- Use SSCC-18 (GS1-128) on pallets when the retailer requires ASN-based receiving.
- Verify print quality to ISO/IEC 15416 grade C or better; ask the Thai printer for a verification report, not just a photo.
Carton and pallet marking
- Shipping marks: importer, PO number, item, case quantity, carton n of N, gross/net weight, dimensions, made in Thailand.
- Cartons stamped with the correct case pack — mismatched cases are the number-one 3PL chargeback.
- Pallets: 48x40 in for the US market, not the 1100x1100 mm Asian standard, unless your 3PL says otherwise. Heat-treated ISPM 15 stamp if wooden.
Artwork approval workflow that avoids reprints
- You supply dielines and a print-ready PDF with fonts outlined.
- Factory returns a digital proof within 3 days.
- You approve in writing, then request a physical printed sample before mass printing.
- Golden sample sealed and photographed by both sides; inspection references it at pre-shipment.
Skipping step 3 is how 20,000 cartons arrive with the wrong Pantone.

FAQ
Can I buy a single UPC code online instead of a GS1 prefix?
You can, but Walmart, Costco, Target and most grocery chains verify brand ownership in the GS1 registry and will reject resold codes.
Does "Made in Thailand" have to be on the product or just the box?
On the article itself where feasible, in a conspicuous place, legible and permanent. Marking only the carton is allowed only in limited cases under 19 CFR 134.
What pallet size should Thai suppliers use for US shipments?
48x40 inch GMA-style pallets for most US retail and 3PL networks, heat-treated and ISPM 15 stamped.
Who pays for a barcode reprint if scans fail at the DC?
Put it in the PO terms: failed verification is a supplier defect and reprint or relabel cost is theirs. Without that clause you will absorb it.
Should labeling be applied in Thailand or at a US 3PL?
Thailand, in nearly every case. US per-unit labelling runs several times the Thai cost and adds days to inbound processing.
What barcode grade do US retailers require?
Most vendor manuals require ISO/IEC 15416 grade C (1.5) or better; some grocery programs require grade B.
