US Bedding Flammability: 16 CFR 1632 & 1633 Explained

16 CFR Part 1633 is the US federal open-flame standard for mattresses and mattress sets; 16 CFR Part 1632 is the cigarette (smoldering) ignition standard. They primarily regulate mattresses, not sheets, duvet covers or towels.

Bed linen (sheets, covers, pillowcases) is generally not subject to 1632/1633 — those apply to the mattress itself. However, importers should confirm requirements for their specific product, and some items (e.g. certain made-up or filled products) or markets may carry additional rules. Children's products carry separate requirements.

We help you confirm what your specific product requires for the US market and arrange relevant testing. For mattress-related items we work to the applicable standard; for linen we supply documentation buyers typically request (e.g. OEKO-TEX, fiber content, care labeling).

Do hotel sheets need flammability certification in the US?

Generally no — 16 CFR 1632/1633 apply to mattresses and mattress sets, not to sheets, duvet covers or towels. Always confirm requirements for your specific product with a CPSC-accredited lab.

What about children's bedding?

Children's products carry additional US requirements (e.g. CPSIA). Confirm the rules for your specific product and age grade with the CPSC or an accredited lab.

Can you arrange flammability testing?

Yes — where your product requires it, we arrange testing with accredited labs such as SGS or Intertek.
