SC for-hire PROPERTY carriers (not passenger/HHG/hazwaste) register intrastate
via the SCDMV Certificate of Compliance (COC), not a PSC certificate. This adds:
- sc_coc_pdf_filler.fill_sc_coc(): fills the official SCDMV Form COC from
intake (business name, officers, physical/mailing address, phone), picks
New vs Renewal, and stamps the coverage class (E-L low-value / E-LC).
Field names in the source PDF are auto-generated + offset from their labels;
mapped here by verified on-page geometry. Verified by render.
- suggest_coverage_class(): E-L for low-value cargo (scrap/dump/aggregate),
else E-LC (safer default).
- gov_fee: SC intrastate fee corrected from $0 placeholder to the real $25
COC new-application fee (renewals $0), billed at cost.
The carrier's INSURER files the Form E (liability) + Form H (cargo, E-LC only)
directly with SCDMV; we collect the COC app + $25 and submit it.
