GCC for mattresses (16 CFR Parts 1632 and 1633)

Mattresses sold in the United States are regulated by two flammability rules: 16 CFR Part 1632 (cigarette/smoldering ignition) and 16 CFR Part 1633 (open-flame resistance for mattress sets, in effect since 2007). Both require certification on a General Certificate of Conformity, and both are on the CPSC’s list of rules requiring third-party testing by an accepted laboratory.

Which products are in scope

  • Innerspring, foam, latex, and hybrid mattresses — adult and juvenile sizes.
  • Mattress foundations and box springs, and mattress sets (the combination matters for Part 1633).
  • Futons, sofa-beds, waterbeds, and RV or camper mattresses: several of these have specific treatment under the rules, so confirm scope with your laboratory before certifying.
  • Upholstered furniture is a different product family — see the painted-furniture GCC page if that is your category.

What the two rules require

  • Part 1632: resistance to smoldering ignition from cigarettes on the bare surface and over prescribed cover materials.
  • Part 1633: open-flame resistance measured on a full mattress set — the rate and extent of heat release must stay under the rule’s limits.
  • Both rules require testing by a CPSC-accepted third-party laboratory, prototypes per production group, and permanent labeling (Part 1633 labels must remain legible and attached).

Issuing and keeping the certificate

The importer or domestic manufacturer issues the GCC citing Parts 1632 and 1633, with the certifying party’s US contact details, the prototype and production details behind the tests, and the dates and places of manufacturing and testing. Marketplace and customs checks increasingly ask for the certificate together with the underlying test report, so store them as a pair — and reissue the certificate when the construction, materials, or factory change.

Questions people ask

Do mattress toppers need a GCC?

Part 1632 historically applied to certain padded toppers and pads depending on construction and thickness. Scope for toppers is a known gray area — have your laboratory classify the specific product before you decide whether to certify.

Is a separate certificate needed for each size?

Certificates can cover products that are identical in all relevant respects. Different constructions, foam types, or factories generally need their own testing and their own certificate.

Does a baby crib mattress need this too?

Crib mattresses must meet the flammability rules like other mattresses, and because they are children’s products they can also carry additional children’s-product requirements — certified on a CPC. Confirm with your laboratory.
