Content and sources
Where does the content come from?
From the original publication: the DOF, the Cámara de Diputados, SAT, ANAM and the Secretaría de Economía in Mexico; the eCFR, USITC and CBP in the United States. Every lesson and every answer cites the provision and its date.
What happens when the law changes?
The Radar detects the publication, links the provisions that change and flags the lessons that cite them. Those lessons show as “under review” until a person updates them.
How does Pregúntale answer?
Only with texts from the Biblioteca, citing every statement to the provision in force on the date of the question. When it finds no basis, it abstains. For tariff classification it proposes options; the decision is yours and your customs broker's.
Who writes the lessons?
They are drafted from the sources, with the help of artificial intelligence tools, and a person reviews and approves every lesson before it is published.
Is it in English?
The interface is in Spanish and English. Courses are published in Spanish first; English versions will follow.
