FDA Drug & Cosmetic Labeling Compliance: A Complete Guide for US Market Entry (2026)

FDA labeling compliance is one of the most underestimated requirements for foreign manufacturers entering the US market. A product can be properly registered and correctly listed — and still be refused at the US border because of a labeling error. Under the FD&C Act, non-compliant labeling makes a product misbranded — a federal violation that can result in import refusal, seizure, or injunction.

Why Labeling Compliance Matters More Than Manufacturers Realize

The FDA reviews labeling at the point of import. US Customs and Border Protection can flag products for labeling review. Importers who receive a Notice of FDA Action citing labeling violations face a difficult choice: relabel in a bonded warehouse at significant cost, or allow the shipment to be refused and returned.

FDA Drug Labeling Requirements

OTC Drug Labeling: Drug Facts Format

Over-the-counter drug labels must comply with the Drug Facts format under 21 CFR 201.66. The format requires active ingredients, uses, warnings, directions, and inactive ingredients in a standardized layout with specific typography. See our Drug Listing & SPL Compliance service for full OTC drug compliance support.

Structured Product Labeling for Drug Listing

Drug manufacturers must submit label content in Structured Product Labeling (SPL) format as part of drug listing. Every drug marketed in the US must have a current SPL submission on file. Physical labels that don't match the SPL create a compliance gap that can trigger FDA enforcement.

FDA Cosmetic Labeling Requirements

INCI Ingredient Declaration

All US cosmetics must bear a complete ingredient declaration using INCI names in descending order of predominance. Common errors include using trade names or non-INCI nomenclature, listing ingredients in wrong order, and omitting colorants or fragrance components. Each error constitutes misbranding.

MoCRA Labeling Updates

MoCRA introduced new labeling requirements being phased in. Fragrance allergen disclosure is under active FDA rulemaking. See our full MoCRA compliance service for the latest labeling requirements for cosmetic brands.

Combination Products: Drug-Cosmetic Overlap

Products intended to both beautify and treat a condition — anti-dandruff shampoo, fluoride toothpaste, sunscreen, acne treatments, antiperspirants — are regulated as drugs. These must meet drug labeling requirements, not cosmetic ones. Foreign manufacturers who market these as cosmetics in the EU and import them into the US without drug-compliant labeling face significant compliance risk.

Label Review Process for Foreign Manufacturers

Pre-Market Label Review

The most effective way to avoid import labeling violations is a pre-market label compliance review before manufacturing begins. Our review assesses all FDA labeling requirements, identifies claims that may trigger drug classification, confirms INCI accuracy for cosmetics, and verifies Drug Facts format compliance for OTC drugs.

Pre-Shipment Label Audit

A pre-shipment label audit provides a final checkpoint before goods leave the manufacturer. Catching a labeling error before shipment is far less expensive than catching it at the US border.

Language Requirements

All required label information for US products must appear in English. Products with multilingual labels must include all FDA-required information in English. Non-English ingredient names or directions do not satisfy US requirements.
