Mexico Regulatory Changes 2026: Customs, COFEPRIS, EPR, Chemical Compliance And Market Access Guide

What Mexico’s 2026 Regulatory Changes Mean for Manufacturers, Importers, Chemical Suppliers and Product Compliance

Mexico has become a more demanding market for companies that want to enter, import, sell and remain compliant in 2026.

This year has brought significant changes across customs, tariffs, sanitary enforcement, agricultural products, circular economy and chemical management. The result is a regulatory environment where companies increasingly need to manage compliance across the entire product lifecycle from import documentation and customs valuation to advertising, registration, product stewardship and end-of-life obligations.

For importers, one of the biggest developments is the introduction of new tariffs affecting 1,463 tariff lines, particularly for goods originating from countries without a trade agreement with Mexico.

At the same time, Mexico is moving toward greater digitalization of customs processes. The Electronic Value Manifestation is implemented from 1 November 2026 through 15 January 2027, depending on the customs regime.

For companies already selling products in Mexico, COFEPRIS enforcement is also becoming more visible, particularly in digital advertising. More than 31,155 irregular advertisements had been suspended during 2026 by August, covering social media and e-commerce platforms.

Why Mexico Regulatory Compliance Matters in 2026

Mexico’s regulatory environment is increasingly connecting:

• Customs and import compliance
• Product classification
• Sanitary registration
• Advertising compliance
• Agricultural chemical protection
• Chemical management
• Circular economy
• Extended Producer Responsibility (EPR)
• Environmental product obligations

Companies therefore need to look beyond simply obtaining an import authorization or product registration.

A compliant product also needs accurate customs data, appropriate claims, compliant advertising, reliable supplier information and lifecycle controls.

Key Mexico Regulatory Developments in 2026

The tariff reform covering 1,463 tariff lines entered into force on 1 January 2026 and covers sectors including automotive, textiles, apparel, plastics, steel, appliances, toys, furniture, footwear, paper and other products.

Mexico Import Compliance: New Tariffs and Electronic Valuation

One of the most significant changes for international businesses is the reform affecting 1,463 tariff classifications.

The measures primarily affect imports from countries where Mexico does not have an applicable free-trade agreement. Companies should therefore verify the country of origin, HS/TIGIE classification and preferential treatment eligibility before calculating landed costs.

The reform includes tariff rates ranging from 5% to 50%, depending on the product and classification.

Electronic Manifestation of Value

The MVE is being introduced gradually through Mexico’s foreign-trade single window.

SAT, ANAM and ATDT confirmed the phased schedule in October 2026. gob.mx

Importers should therefore review commercial invoices, valuation information, contracts, supplier documentation and customs data flows before the applicable implementation date.

Customs Broker and Importer Responsibilities

Mexico’s customs reforms also reinforce the importance of clearly defined responsibilities between importers, customs agencies and customs brokers.

The amended Customs Law contains provisions under which certain infringements arising from the actions of customs agents or agencies may result in penalties being charged to them.

The national implementation of customs agencies was also completed in July 2026, giving greater operational significance to the agency model.

For companies, this makes broker governance and customs data quality increasingly important.

Recommended controls include:

• Tariff classification verification
• Origin determination
• Customs valuation review
• Product description controls
• Broker instructions
• Import documentation reconciliation
• Periodic customs audits
• Change-control procedures

COFEPRIS Enforcement: Digital Advertising Is Under Greater Scrutiny

Market access does not end when a product clears up customs.

COFEPRIS has significantly increased surveillance of product advertising on social media and e-commerce platforms.

By August 2026, authorities reported the suspension of 31,155 irregular advertisements, including advertisements on Facebook, Instagram, TikTok and Mercado Libre.

This is particularly relevant to companies’ marketing:

• Cosmetics
• Food supplements
• Medical products
• Health-related products
• OTC products
• Personal care products
• Other products subject to sanitary advertising requirements

Companies should review not only their product labels but also website content, marketplace listings, influencer content, social-media claims and promotional materials.

Agricultural Chemical Products: 10-Year Data Protection

Another important 2026 development concerns agricultural chemical products.

A reform published in April 2026 introduced a 10-year protection period for safety and efficacy relating to new agricultural chemical products, alongside other changes affecting registration and renewal procedures.

This can be particularly relevant for companies developing or commercializing:

• New active ingredients
• Agrochemical products
• Crop protection products
• Agricultural chemical formulations
• Innovative pesticide products

Companies should assess how the new data-protection framework affects registration strategy, intellectual-property planning, product lifecycle management and generic-entry strategies.

Circular Economy and Extended Producer Responsibility

Mexico also moved forward with a major environmental policy development in January 2026 by issuing the General Law of Circular Economy.

The law establishes mechanisms designed to increase product life, reduce waste, promote recovery and recycling, and strengthen Extended Producer Responsibility (EPR).

The law also provides for implementation mechanisms, a national circular economy program and producer responsibility measures.

This means companies should begin evaluating product stewardship and end-of-life obligations, rather than treating environmental compliance as a separate issue from product commercialization.

Mexico’s Emerging Chemical Regulatory Framework

Mexico currently operates chemical management through a multi-agency regulatory structure, rather than a single comprehensive chemicals law.

However, a significant emerging development was highlighted at the Latin America Regulatory Cooperation Forum (LARCF) in Buenos Aires in September 2026.

Industry regulatory sources reported that Mexican officials indicated a draft national chemical framework law, under development for several years, could potentially be presented for public consultation as early as January 2027. This remains an emerging policy signal rather than an enacted requirement, so companies should not treat the timeline as confirmed legislation.

For chemical manufacturers and importers, this makes early regulatory readiness particularly valuable.

Conclusion

Mexico’s 2026 regulatory environment demonstrates a clear shift toward more structured, digital and lifecycle-based compliance.

For companies, entering Mexico increasingly requires more than customs clearance or product registration. Businesses need to consider tariffs, customs valuation, broker controls, COFEPRIS enforcement, product claims, agricultural data protection, circular economy responsibilities and emerging chemical regulation as connected elements of market access.

The key message for manufacturers, importers and global suppliers is simple:

Compliance in Mexico is becoming a lifecycle responsibility from getting the product through customs to keeping it compliant in the market and managing its end-of-life obligations.

Companies should use 2026 to review their product portfolio, customs processes, regulatory documentation, supplier controls, advertising claims and environmental responsibilities while preparing for further regulatory developments in 2027.
