Product Labeling and Marking Requirements for US Imports
Getting your goods into the United States isn't just about paying duties and filing the right paperwork. If your products aren't marked and labeled correctly, CBP can detain your shipment, force you to re-label at your own expense, or flat-out refuse entry. Penalties under 19 USC §1304 can hit $5,000 per violation for willful non-compliance.
This guide covers the core requirements you need to know before your next shipment arrives at a US port.
Why Labeling Compliance Matters More Than You Think
Most importers think of labeling as a minor detail. It's not.
CBP examines marking compliance during Focused Assessment audits and random cargo examinations. If an examiner finds your goods are unmarked or improperly marked, your entire shipment can be held under a CF-4647 Notice to Mark and/or Redeliver. That means you're paying drayage, warehouse storage (often $75–$150/day per container), and re-labeling labor — all before your goods ever reach your warehouse.
For a 40-foot container of consumer goods, a marking hold can cost you $3,000–$8,000 in demurrage and remediation. That's before you factor in delayed cash flow and broken delivery commitments.
Fix labeling issues at the factory, not at the port.
Country of Origin Marking: The Non-Negotiable Baseline
19 CFR Part 134 requires that every article imported into the United States be legibly marked with the English name of the country of origin. This applies to the article itself and, in some cases, its container.
What "Legibly Marked" Actually Means
CBP isn't looking for microscopic text buried under a flap. The marking must be:
- Conspicuous — visible without having to unwrap or disassemble the product
- Legible — readable without magnification
- Permanent — must survive normal handling and use (not a sticker that peels off in a warehouse)
- In English — "Fabriqué en France" doesn't satisfy the requirement; it must say "Made in France"
Acceptable methods include molding, cast-in labels, etching, stamping, or permanent ink. Pressure-sensitive stickers are only acceptable when permanent marking is technically impractical — and CBP has a narrow view of what "impractical" means.
The Substantial Transformation Rule
The country of origin is the country where the goods were last substantially transformed. This matters enormously if you're sourcing components from one country and assembling in another.
A practical example: If you source cut-and-sewn garment panels from Bangladesh and sew them together in Vietnam, the country of origin is Vietnam. If you import raw steel wire from China and manufacture springs in Mexico, the origin is Mexico.
This isn't just a labeling question — it determines duty rates, eligibility for preferential trade programs (USMCA, GSP), and exposure to Section 301 tariffs on Chinese-origin goods.
Products Exempt from Article Marking
Some products don't need to be individually marked. Exemptions under 19 CFR §134.33 include crude substances, goods valued under $200 that are not for resale, and certain bulk commodities. But if you're selling consumer products through e-commerce, you almost certainly don't qualify for these exemptions. Don't assume — confirm with your customs broker.
Textile and Apparel: The Most Regulated Category
If you import clothing, fabric, towels, bedding, or any fiber-based product, you're operating under the Textile Fiber Products Identification Act (15 USC §70) and FTC regulations at 16 CFR Part 303.
Required Label Elements for Apparel
Every garment sold in the US must have a label disclosing:
- Fiber content — listed by generic fiber name (e.g., "60% Cotton, 40% Polyester"), in descending order by weight. If a fiber makes up less than 5% of the total, it can be listed as "other fiber" unless it has a functional significance.
- Country of origin — satisfies the CBP requirement simultaneously
- Manufacturer or dealer identity — a registered RN number (Registered Number issued by the FTC) or WPL number, or the company's full name
- Care instructions — required under a separate FTC rule (16 CFR Part 423)
Care Labeling: 16 CFR Part 423
Care labels must be permanently attached and remain legible for the useful life of the garment. They must appear at a location consumers will find before purchase — usually the neck or side seam.
The FTC requires that care instructions be based on the most severe process the garment can withstand. If you say "Machine Wash Cold," you're certifying the garment won't be damaged by that process. If it shrinks 30% in cold water, you have a problem — both with the consumer and with FTC enforcement.
ASTM D5489 standard care symbols are widely used and accepted, but you must include plain English instructions alongside symbols for US market goods.
Children's Products: Tracking Labels and CPSC Requirements
If you import any product intended for children under 12, the Consumer Product Safety Improvement Act (CPSIA) applies. This includes toys, clothing, juvenile furniture, and school supplies.
Permanent Tracking Labels
Under 15 USC §2063(a)(5), every children's product must have a permanent, distinguishable tracking label that includes:
- Manufacturer or private label name
- Location and date of production (city/country and month/year)
- Batch or run number
- Any other information allowing the full supply chain to be traced
This is not the same as a country of origin mark. It's a separate, additional requirement. Many importers overlook this and only discover the problem during a CPSC audit or after a product recall.
The tracking label must appear on the product itself and on its packaging. For small items where a label is impractical (a small toy part, for example), the packaging label alone may suffice — but document your reasoning.
Food, Supplements, and Consumables: FDA Labeling
If your product is ingested, FDA labeling rules under 21 CFR Parts 101–199 govern what must appear on the label. This is a deep topic, but here are the critical elements most e-commerce importers get wrong:
Required Elements on Food Labels
- Statement of identity (what the product is)
- Net quantity of contents — in both US customary and metric units
- Nutrition Facts panel — format specified by FDA; don't use a foreign-market format
- Ingredient list — in descending order by weight, using common names
- Allergen disclosure — under FALCPA, the 9 major allergens (milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, sesame) must be clearly declared
- Name and address of the US distributor or importer
Foreign-language labels are not acceptable for US retail sale. A product manufactured in Korea with Korean-language labels must be relabeled before it enters US commerce. This can be done at a bonded warehouse before CBP release — but it adds cost and time.
Electronic and Electrical Products: FCC and UL
Products that emit radio frequency energy — anything with Bluetooth, Wi-Fi, or wireless functionality — need FCC authorization before they can be imported or sold in the US.
The label must display the FCC ID in a location that is accessible to the end user. For devices with embedded displays, the FCC ID can appear in the device's electronic menu, but this must comply with 47 CFR §2.926.
Products must also comply with applicable safety standards. While the US doesn't mandate CE marking (that's Europe), retailers and insurers increasingly require UL certification or compliance with UL standards. Some states — California in particular — have additional requirements under Proposition 65 that require warning labels if products contain chemicals above defined thresholds.
Common Mistakes That Trigger CBP Holds
Here's what actually causes shipments to get flagged:
- "Made in PRC" vs. "Made in China" — CBP accepts both, but "PRC" alone without "China" has historically caused issues at some ports. Use "China" to be safe.
- Sticker-only marking on durable goods — A sticker on a cast iron pan is not acceptable permanent marking.
- Marking only the outer carton — If the article will be sold individually, the article itself must be marked, not just the master carton.
- Missing RN numbers on apparel — FTC can fine you; more practically, major retailers will refuse your goods.
- Foreign-format Nutrition Facts — FDA's format is specific. A panel from a Canadian or EU market product doesn't comply.
- No CPSIA tracking label on children's products — This is one of the most commonly missed requirements for new importers.
How to Build a Compliant Labeling Process
The most efficient approach is to build labeling compliance into your purchase order and factory audit process, not your port clearance process.
- Create a labeling spec sheet for each product that lists every required element, exact placement, minimum font size, and acceptable methods. Send it to your factory with your PO.
- Request pre-production samples and verify label content before bulk production begins.
- Use your freight forwarder or customs broker to review labeling against current CBP requirements before goods ship. A 30-minute review at origin costs far less than a hold at the port.
- Document everything — keep records of your country of origin determinations, fiber content certifications, and any FCC authorizations. CBP can audit you up to 5 years after entry.
Getting labeling right isn't complicated — but it requires being deliberate. The brands that get held up at ports are almost never surprised by the rules. They just assumed someone else was handling it.
