CPSC eFiling for Fireworks: flagged HTS codes and citation codes

CPSC's October 2026 HTS list places 2 HTS codes in the Fireworks category (2 CP1) across 1 HTS heading(s).

What the flags mean. CPSC and CBP flag these HTS codes in ACE. CPSC's list labels CP2 as "CPSC Certificate Related Data is Required" and CP1 as "CPSC Certificate Related Data May be Needed". CPSC says the ~600-code list covers HTS codes that likely include a product subject to a mandatory standard or deemed high-risk, but it does not cover every HTS code where a certificate may be required. The importer must eFile whenever a certificate is required, whatever the HTS code. If your product needs no certificate, a voluntary Disclaim may be filed, which CPSC says may benefit your risk score (CPSC HTS list, Oct 2026; Disclaim A vs B).

Rules commonly cited for Fireworks

  • 1507: 16 CFR 1507: Fireworks Devices

Children's versions (designed or intended primarily for children 12 and under) need a Children's Product Certificate based on third-party testing; general-use versions need a GCC when a rule applies. Use the free checker to narrow it down.
