On January 1, 2022, the National Customs Agency (ANAM) started full operations as an independent agency outside Mexico’s Secretariat of Finance and Public Credit (Secretaría de Hacienda y Crédito Público or SHCP).  Previously, customs-related functions were overseen by Mexico’s Tax Administrative Service (Servicio de Administración Tributaria or SAT, part of the SHCP).

ANAM coordinates its tasks with the Departments of Defense and Navy to maintain security at customs border crossing points and work with SAT for the proper collection, administration, and accounting. Recent modifications to the internal regulations of the National Customs Agency, give management authority over the country’s customs services at ports and land ports of entry to the Secretaries of National Defense (SEDENA) and the Navy (SEMAR) .

Some U.S. exporters have expressed concerns about SAT/ANAM procedures. These include insufficient prior notification of procedural changes, inconsistent interpretation of regulatory requirements at different border posts, and uneven enforcement of Mexican standards and labeling rules.

Agricultural exporters note that Mexican inspection and clearance procedures for some agricultural goods can be long, burdensome, non-transparent, and unreliable.

Customs procedures for express packages continue to be difficult. Under the United States-Mexico-Canada Agreement (USMCA), Mexico amended its General Foreign Trade Rules, changing its “tasa global,” a combination duty and charge on all shipments entering under simplified clearance (de minimis and informal entry) methods, including shipments from the United States and Canada. Goods from the United States valued at USD 50 or less will not be charged duties or taxes. Goods valued from USD 50 to USD 117 will be charged a 17 percent tax but will not be charged duties.

Customs Trade Facilitation for Imports via courier and parcel companies

On May 9, 2022, the Mexican Ministry of Economy published an updated agreement on the General Rules and Criteria Regarding Foreign Trade. This change in the regulation would allow Mexican importers to import through courier and parcel companies:

  • Without having a Mexican Customs License / Importer of record (Padron de Importadores);
  • Without hiring a Customs Broker Agent;
  • Exempting Mexican Standards / NOM;
  • With a new threshold for imports up to USD 2,500 value at the Mexican Customs Ports.

Before May 9, 2022, the threshold exemption for NOMs was USD 1,000. With this change, the benefit now rises to USD 2,500 exclusively for courier and parcel companies.

This change does not impact global import tax rates applied to imports via courier and parcel companies, which remain the same.

We strongly recommend that U.S. exporters communicate with their Mexican clients about these new benefits. Be aware that the Mexican government can limit these imports if it is suspected that the importer is using this scheme to avoid regulations, restrictions, or tax payments.

The Mexican Ministry of Economy published on June 7, 2022, a decree issuing the import and export general tax law, which contains new tariffs, taxes, and provisions on the Commercial Identification Numbers (NICO) and the Harmonized Tariff Schedule (HS Codes), following the full implementation of the Seventh Amendment of the Harmonized System directed by the World Customs Organization (WCO) to their membership. The target changes include international product codes for global trade.

U.S. exporters and Mexican importers are responsible for making necessary updates and using the correct HS code. Since HS codes establish tariff classification for goods, it is critical for U.S. exporters to be aware of their HS codes when shipping to Mexico.  The amendment consists of around 350 changes which will add some goods that will receive new HS codes, change some definitions that must be improved, and delete other codes because the products are considered obsolete. 

U.S. exporters should contact their Mexican clients and partners to be aware of the process and changes in the HS code system to avoid mistakes and delays at Mexican ports of entry. Simply put, using incorrect HS codes can unnecessarily complicate cross-border sales. During 2021, some companies experienced delays in the import process due to the incorporation of “trade identification numbers/TIN” – Numero de Identificacion Comercial/NICO.
