In the bulk upload CSV, an exclusion code goes in the Citation Codes column of a lab entry whose type is NOL (no lab).
Source row 50, sheet "Testing Exclusions", workbook titled September 2026 Update (CPSC library date 2025-12-18)
In the bulk upload CSV
Add a lab entry of type NOL (no lab) and put the code in its Citation Codes column, for example Lab 2 Type = NOL and Lab 2 Citation Codes = 1610.1(d)(2). Use it only when the certificate is required for another rule; the rule it excludes, 1610, still belongs on the certificate.
CPSC's workbook describes this row as "16 CFR 1610.2(d)(2)" in the text while the code column says 1610.1(d)(2). The code column is shown here.
