Customs law reform widens broker liability and paperwork
Published 19 November 2025 · Diario Oficial de la Federación
What changed
A reform of the Ley Aduanera makes the partners of a customs agency jointly liable for duties on the operations it handles, requires a full electronic file proving each import, and sets the broker's licence at 20 years, renewable. Most of it applies from 1 January 2026, with some articles one or three months later.
Who it affects
All industries. Product types on our rules page: all fifteen.

What to do
Expect your customs broker to ask for more: a complete electronic file proving each import, and closer checks, because the agency's partners now answer for the duties on its operations. Have invoices, origin and product documents ready before goods reach the border, and confirm your broker's licence is current.
