One of the most critical challenges when entering the U.S. market is product quality certification. Among these, compliance with textile labeling regulations is especially strict. Noncompliance can lead to product removal from shelves or even legal risks. What are the key points of the U.S. regulation 16 CFR 303 on fiber content labeling?
Ensure consumers receive accurate information regarding fiber content, country of origin, and manufacturer. The regulation aims to eliminate false advertising, protect consumer rights, and maintain fair competition.
