Manufacturers and importers of carpets and rugs intended for general use must certify in the General Conformity Certificate (GCC) that their products comply with applicable standards after testing or reasonable testing projects, ensuring compliance and/or affixing appropriate labels according to the standards. 16 CFR 1630 and 16 CFR 1631 are surface flammability standards established by the U.S. Consumer Product Safety Commission (CPSC) for carpets and rugs, aimed at reducing the risk of fire caused by carpets coming into contact with small ignition sources.
1. Scope of Application
01
16 CFR 1630 (Large Carpet Standard)
Size Definition: Carpets with a single dimension exceeding 1.83 meters (6 feet) or a total area greater than 2.23 square meters (24 square feet).
Typical Scenarios: Carpets installed in large areas such as living rooms, offices, and hotel lobbies.
Exceptions: Resilient flooring (such as linoleum and vinyl tiles) is not applicable.
02
16 CFR 1631 (Small Carpet Standard)
Size Definition: Carpets or rugs with a single dimension not exceeding 1.83 meters and a total area not greater than 2.23 square meters, such as door mats and small bedside rugs.
Special Requirements: Small carpets that do not meet the standards may still be sold but must be permanently labeled with the warning: “FLAMMABLE (FAILS U.S. DEPARTMENT OF COMMERCE STANDARD FF 2-70): SHOULD NOT BE USED NEAR SOURCES OF IGNITION”.
2. Frequently Asked Questions
01
How to distinguish between 16 CFR 1630 and 16 CFR 1631?
Size is the core criterion: with 1.83 meters and 2.23 square meters as boundaries, large carpets apply to 1630, while small carpets apply to 1631.
Testing stringency: 1631 has stricter requirements for flame spread rate and ember drop for small carpets; for example, small carpets must extinguish within 4 seconds, while large carpets are allowed a longer burn time.
02
Are natural fiber carpets exempt?
Wool carpets: If the wool content is ≥90%, an exemption can be applied for, but a composition testing report must be submitted.
Alternative cleaning methods: Hand-woven wool or animal skin carpets can use special cleaning procedures, but must declare compliance with 16 CFR §1630.61 or 16 CFR §1631.61 on the label.
03
What are the details of labeling?
“T” mark: Must be clear and permanently affixed, such as sewn on the edge or printed on the care label.
Warning label position: Small carpets that do not meet the standards must be prominently labeled on the product surface or packaging, avoiding obstruction.
3. Conclusion
16 CFR 1630 and 16 CFR 1631 are mandatory standards for carpets entering the U.S. market. Companies must select the corresponding tests based on product size to ensure compliance with labeling, certification, and testing processes. For children’s products or flame-retardant treated products, additional tracking label and third-party certification requirements must be met. By strictly enforcing these standards, the risk of fire can be effectively reduced, ensuring consumer safety.
