Pick a lane and work the checklist -- each document is tagged with when it's needed and who typically files it, so nothing surfaces for the first time at the border.
This is an organizational checklist, not customs or legal advice -- requirements vary by commodity, value, and carrier program (FAST, C-TPAT, etc). Confirm specifics with your licensed customs broker before relying on it.
0 / 4 required documents checked
Commercial Invoice
Filed by: Shipper / exporter
Full description, HS/HTS classification, value, and Incoterms for every line item -- this is what the Mexican customs broker builds the pedimento from, so gaps here become delays at the border.
Learn morePacking List
Filed by: Shipper / exporter
Piece count, weight, and packaging detail matching the commercial invoice.
USMCA/T-MEC Certificate of Origin
ConditionalFiled by: Shipper / exporter
A signed statement (no fixed government form) certifying the goods qualify as North American originating goods.
Only needed if the shipper/importer is claiming preferential (reduced/zero) tariff treatment under USMCA/T-MEC/CUSMA -- goods can still cross without it, just without the tariff break.
Learn moreComplemento Carta Porte (CFDI)
Filed by: Mexican customs broker / your carrier's Mexican counterpart
SAT's electronic bill-of-lading supplement, required for the Mexican inland leg of the move (including the stretch from the border to the consignee) -- tied to a CFDI, not the US-side paperwork.
Learn morePedimento de Importación
Filed by: Licensed Mexican customs broker (agente aduanal)
Mexico's official customs entry declaration -- only a licensed Mexican broker can file it. This is the document that actually clears the goods into Mexico.
