Citation codes

CPSC's HTS list gives a product category, not citation codes. These rows of CPSC's citation list mention "mattresses" products by name. It is a text match, not a CPSC mapping: you decide which rules apply to your product, and others (for example lead or phthalate limits on children's products) may apply too.

  • 1632 16 CFR 1632: Standard for the Flammability of Mattresses and Mattress Pads CPCGCC
