HTS 84.33 CPSC eFiling flags: Harvesting or threshing machinery, including straw or fodder balers; grass or hay mowers;
3 ten-digit HTS codes under heading 84.33 appear on CPSC's eFiling HTS list (Oct 2026): 3 CP1. CPSC product category: Power Mowers.
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).
