Product Labeling Requirements and Regulations
Universal Labeling Requirements (All Products)
Regardless of product category, the Federal Trade Commission requires three elements on every consumer product sold in the United States. The product identity must be stated clearly, telling the consumer what the product is. The net quantity of contents must appear on the principal display panel, expressed in both US customary units and metric units for most products. The name and place of business of the manufacturer, packer, or distributor must be on the label, including a street address (a PO Box alone is not sufficient unless your street address is on file with the postal service).
Country of origin labeling is required by US Customs and Border Protection for all imported products. The label must state "Made in [country]" or "Product of [country]" in English, in a conspicuous location. For products that claim "Made in USA," the FTC requires that all or virtually all manufacturing and components originate in the United States. Claiming "Made in USA" on a product assembled domestically from imported components violates FTC rules and can result in enforcement action.
UPC barcodes are not legally required but are practically mandatory for selling on Amazon, in retail stores, and through most distribution channels. Purchase a GS1 company prefix ($250 for 10 barcodes, $750 for 100) to generate legitimate UPC codes for your products. Third-party barcode resellers offer cheaper alternatives, but Amazon and major retailers occasionally reject resold barcodes, and GS1-issued codes are the only ones guaranteed to work everywhere.
Food Product Labeling
Food products have the most detailed labeling requirements of any consumer product category, enforced by the FDA under 21 CFR Part 101. Required label elements include the following.
The Nutrition Facts panel must follow the updated 2020 format with calories displayed in a larger, bolder font than other nutrients, added sugars listed as a separate line item below total sugars, updated daily values reflecting current scientific consensus, dual-column formatting for packages that can be consumed in one or two sittings, and specific serving sizes based on Reference Amounts Customarily Consumed (RACCs) rather than manufacturer-determined portions. The panel font size minimums depend on the available label area: products with less than 12 square inches of available label space can use a smaller "tabular" or "linear" format.
The ingredient list must list all ingredients in descending order of predominance by weight. Sub-ingredients in compound ingredients (like "enriched flour" which contains multiple components) must be listed either in parentheses following the compound ingredient or individually in the main ingredient list in their correct position by weight. Color additives must be listed by their common or usual name.
Allergen declarations are required for the nine major food allergens: milk, eggs, fish (with species identified), crustacean shellfish (with species identified), tree nuts (with specific type identified), peanuts, wheat, soybeans, and sesame. Declare allergens either within the ingredient list using the common allergen name in parentheses or in a separate "Contains" statement immediately following the ingredient list. Do not use both methods on the same label, as this can create confusion if they do not match perfectly.
Dietary Supplement Labeling
Supplement labeling follows the Supplement Facts panel format defined in 21 CFR 101.36, which differs from the Nutrition Facts panel used on food. The Supplement Facts panel must list all dietary ingredients with amounts per serving, the percent daily value (%DV) for ingredients where a DV has been established, a dagger symbol and footnote for ingredients without established DVs stating "Daily Value not established," the serving size expressed as the number of capsules, tablets, or volume, servings per container, and all "other ingredients" (non-active ingredients like gelatin capsules, rice flour filler, magnesium stearate) listed below the panel in descending order of predominance.
Additional required label elements for supplements include the statement "Dietary Supplement" prominently displayed on the principal display panel, the FDA disclaimer for any structure/function claims, the manufacturer or distributor name and address, the net quantity of contents (number of capsules, tablets, softgels, or volume for liquids), and adequate directions for use. If the supplement contains botanical ingredients, the label must identify the plant part used (root, leaf, seed, etc.) and may include the Latin binomial name.
Cosmetic Labeling
Cosmetic labeling requirements are enforced by the FDA under the Fair Packaging and Labeling Act and 21 CFR Parts 701 and 740. The outer packaging (box, sleeve, or overwrap) and the product container may have different requirements based on available space.
The outer packaging must display the product identity (what the product is), net quantity of contents in both metric and US customary units, ingredient declaration listing all ingredients in descending order of predominance using INCI (International Nomenclature of Cosmetic Ingredients) names, name and address of the manufacturer, packer, or distributor, and any required warnings. If a cosmetic product is sold without outer packaging (just the container), all of these elements must appear on the container itself.
Specific warning statements are required for certain cosmetic ingredients and product types. Products containing alpha hydroxy acids (AHAs) should include a sun sensitivity warning. Aerosol products require warnings about flammability and inhalation. Products not adequately tested for safety must bear the statement: "WARNING: The safety of this product has not been determined." Color additives must be FDA-approved for their intended use (some colors approved for external use are not approved for lips or the eye area), and certain colors require batch certification from the FDA before use.
Apparel and Textile Labeling
The FTC regulates clothing and textile labeling under the Textile Fiber Products Identification Act and the Care Labeling Rule. Every garment must include fiber content listing all fibers by generic name and percentage in descending order (for example, "60% Cotton, 35% Polyester, 5% Spandex"), country of origin, the manufacturer's name or registered identification number (RN), and care instructions using either standardized ASTM symbols or written care instructions in English.
Fiber content tolerances allow a 3 percent variance from stated percentages for manufacturing variation. Fibers present at less than 5 percent of the total weight must be listed as "other fiber" unless they serve a specific functional purpose (like elastic waistbands), in which case they can be listed by name. Care labels must be permanently attached to the garment (not on a hang tag that can be removed) and must remain legible for the useful life of the product.
Children's Products Labeling
Products designed for children 12 years and under are regulated by the Consumer Product Safety Commission (CPSC) under the Consumer Product Safety Improvement Act (CPSIA). Beyond standard labeling requirements, children's products must include a permanent tracking label with the manufacturer name and contact information, production date, batch or lot number, and product identification code. This tracking information enables product recalls and safety investigations. Children's products must also be tested by a CPSC-accepted laboratory for lead content, phthalates (in certain materials), small parts hazards, and any applicable product-specific safety standards. A Children's Product Certificate (CPC) must be issued based on the test results before the product can be sold.
Electronics Labeling
Electronic products sold in the United States must comply with FCC regulations for electromagnetic interference. Products that intentionally emit radio frequency energy (Bluetooth devices, WiFi routers, wireless accessories) require FCC certification and must display the FCC ID on the product label. Products that unintentionally emit RF energy (computers, LED lights, motor-driven devices) must comply with FCC Part 15 limits and display the FCC compliance statement. Additionally, products with batteries must comply with UN38.3 testing requirements for lithium batteries and may need specific shipping labels and documentation for air freight.
Amazon-Specific Labeling Requirements
Beyond legal requirements, Amazon has its own labeling policies that can result in listing suppression if not followed. Every product sold through FBA must have an FNSKU barcode (Amazon's internal product identifier) on each unit. Products must not have multiple conflicting barcodes that could cause scanning errors. Expiration dates must be clearly displayed on perishable products in a format Amazon can read (MM/DD/YYYY or MM/YYYY). Products in categories like supplements, food, cosmetics, and children's products may require additional documentation (COAs, test reports, CPC certificates) that Amazon can request at any time. Having this documentation ready before listing your product prevents delays and account-level complications.
