Private Label T-Shirt Labeling Requirements (US Guide)
Printing a design on a blank tee doesn't trigger federal labeling rules — but the moment you cut your own neck label, swap in a private label woven, or start selling a garment you had cut-and-sewn under your own brand, US law requires specific information on that label. Miss one of the four required disclosures and you're not just risking a fine; you're risking a retailer or wholesale buyer rejecting the whole shipment at receiving. Here's exactly what's required, what's optional branding, and how it applies differently to blank tees versus true private label garments.
Why This Matters Even for a Small First Run
The FTC's Textile Fiber Products Identification Act and Care Labeling Rule apply regardless of order size. A 50-unit private label run from a small apparel brand is held to the same labeling standard as a 5,000-unit order from an established label. Retail buyers, Amazon, and import customs brokers all check for these disclosures before a shipment moves — so getting it right before your first production run saves a costly relabeling pass later.
The Four Disclosures US Law Requires on Every Garment
Every private label garment sold in the US needs a label (sewn-in, heat-transfer, or hang tag attached at point of sale) that discloses the following:
| Requirement | What It Means | Common Mistake |
|---|---|---|
| Fiber content | Percentage breakdown by weight (e.g. "100% Cotton") | Rounding without disclosing blend percentages on poly-cotton blanks |
| Country of origin | Where the garment was manufactured, not where it was designed or printed | Listing the print shop's country instead of the blank's country of manufacture |
| RN number or business name | An FTC-issued Registered Identification Number, or the full legal business name | Printing a brand's logo name only, with no RN and no legal entity name anywhere |
| Care instructions | Washing, drying, and ironing guidance covering at least one safe care method | Omitting care instructions on garments relabeled after printing |
RN Number vs. Just Using Your Business Name
You don't need an RN number to sell private label apparel in the US — using your full legal business name on the label satisfies the requirement. But an RN number (free to register with the FTC) is worth getting once you're placing repeat private label orders: it lets you print a short number instead of a long legal name, and it's what larger retail buyers expect to see on a wholesale line sheet.
Care Labels: What You're Actually Required to Disclose
The Care Labeling Rule requires at least one method of care that, if followed, won't damage the garment under normal use — not an exhaustive list of every safe option. For a 100% Pima cotton blank, "Machine wash cold, tumble dry low" is sufficient. You're not required to list bleach, ironing, or dry-clean guidance unless those methods are relevant warnings (e.g., "Do not bleach" if a print would be damaged).
Country of Origin: Why It's Not the Same as "Where We Print"
This is the single most common private label labeling mistake. Country of origin refers to where the blank garment itself was cut and sewn — for Peruvian Pima cotton blanks, that's Peru, not the US print shop that added a logo or the US brand that designed it. A garment can legitimately say "Made in Peru" on its country-of-origin label while also carrying a "Designed in [US City]" marketing claim, as long as the two aren't presented as the same thing.
Does a Blank Tee (No Private Label) Need Any of This?
If you're buying blank tees and reselling them undecorated and unrelabeled, the original manufacturer's label already satisfies these requirements — you don't need to add anything. The obligation shifts to you only once you remove, cover, or replace that original label with your own, which is exactly the point where private labeling begins and compliance becomes your responsibility.
Pre-Production Compliance Checklist
- Confirm your blank's actual country of manufacture with your supplier in writing — don't assume.
- Decide between an RN number and your legal business name before your first label order ships.
- Write one safe care instruction that matches the fabric (Pima cotton: cold wash, low tumble dry).
- Choose your label format — woven, tagless heat-transfer, or hang tag — and confirm it carries all four disclosures, not just your logo.
FAQ
Do I need an RN number to sell private label t-shirts?
No. Using your full legal business name on the label is a legally valid alternative to an RN number, though an RN number is faster to print and more recognizable to retail buyers.
Can I say "Made in USA" if I only printed the design here?
No. "Made in USA" refers to where the garment was manufactured (cut and sewn), not where it was decorated. A blank imported from Peru and printed in the US must still disclose Peru as the country of origin.
Does a small batch of 24 shirts still need compliant labels?
Yes. US labeling law doesn't set a minimum order size exemption — a 24-unit private label run needs the same four disclosures as a 5,000-unit run.
What's the difference between a hang tag and a required label?
A hang tag can carry your brand story and marketing copy, but the four legally required disclosures (fiber content, country of origin, RN/business name, care instructions) must appear on a permanent or point-of-sale label — a hang tag alone, if removed before the customer uses the garment, isn't sufficient on its own for care instructions.
Getting labeling right is one of the few parts of launching a private label line that has a definite correct answer — unlike fit or fabric weight, there's no "it depends." Pair this with a packaging plan (see our private label packaging and tags guide) and a Peruvian Pima cotton blank that's already labeled accurately at origin, and your first production run ships compliant from day one.
