Core conclusions:Starting from January 1, 2026, Mexico will impose temporary tariffs on goods imported from countries without free trade agreements. A total of 1,463 items will be subject to these tariffs, with rates ranging from 10% to 50%. The tariff period will last until December 31, 2026, and can be extended further. This affects imports worth approximately $52 billion, accounting for 8.6% of Mexico’s total imports throughout the year. In April 2026, another 185 items were added to the list of taxable goods, with tariffs increased by 5% to 35%. Under this tariff structure, Chinese factories have only three viable options for importing into Mexico: either reducing the product form to qualify for lower tariffs, using the IMMEX program for local value addition, or completing substantial processing in a third country with which Mexico has a free trade agreement, thereby obtaining origin status.
1. First, understand the tax rate levels clearly: The key is to consider the product’s nature, not the country of origin.
In the 2026 tariff implementation, Mexican tariffs are categorized based on the degree of processing involved: raw materials and simple intermediate products are subject to tariffs ranging from 10% to 15%; semi-finished products and key components are subject to tariffs between 20% and 35%; finished goods and high-value-added products are subject to tariffs between 35% and 50%. These tariffs apply to industries such as automobiles, textiles, steel, household appliances, toys, and furniture. These industries account for 8.6% of Mexico’s total imports. In April 2026, additional 185 tax items were added to the list of taxable goods, with tariffs ranging from 5% to 35%. The majority of these additional tariffs apply to chemicals, cosmetics, textiles and clothing, steel and aluminum products, and automotive parts.
This structure leads to an counterintuitive conclusion: the form in which a product is declared for customs purposes, as well as which tax code it falls under, determine the difference in tax rates, which can exceed 20 percentage points. The distinction between semi-finished products and finished goods depends on whether assembly has been completed, and whether there is any final packaging or labeling attached to the product. Therefore, the first step is not to try to find customers, but rather to compare each product against the Mexican customs codes, in order to determine which category it belongs to.
| Processing forms | Tax rate brackets for the year 2026 | Suitable factory type |
|---|---|---|
| Raw materials and simple intermediate products | 10% to 15% | Upstream factories involved in the production of steel, chemical raw materials, yarn, sheets, etc. |
| Semi-finished products and key components | 20% to 35% | Factories specializing in components, modules, fabrics, and accessories |
| Finished products and high-value-added products | 35% to 50% | Complete machines, consumer goods, and complete equipment factories |
II. Channel 1: Moving the product format to a lower tax rate category
The most straightforward approach is to shift the export format from finished products back to components or semi-finished products. The final assembly and packaging can be carried out by local Mexican factories. As a result, the tax rate can be reduced from 35% to 50% to 10% to 15%, or 20% to 35%. However, this comes with the loss of brand visibility at the end user level. The pricing power is partially transferred to the local assemblers and distributors.
To determine whether it’s worth investing in such a solution, we need to consider two aspects. The first is the difference in tax rates: taking an order worth $1 million as an example, the difference between 35% and 15% represents an additional cost of $200,000. This amount can cover the costs associated with local assembly and secondary packaging. The second aspect is the customer structure: when the end buyers are local retailers or brand owners, they are willing to handle the assembly and labeling process themselves. However, when the buyers are distributors who develop their own sales channels, this approach may lead to a loss of product recognition.
III. Channel Two: The IMMEX initiative aims to provide local value-added services, but the risks are increasing.
IMMEX is a temporary import system in Mexico, designed for manufacturing, processing, and export services. Qualified enterprises can import raw materials and components under bonded conditions. After processing them in Mexico, these products can be exported, and the enterprise can benefit from delayed payment of taxes related to imports. In the past, many Chinese companies used Mexico as a transit point for their exports.
In 2026, the circumstances have changed. Mexico has imposed a temporary ban on the import of finished shoes. At the same time, customs authorities have strengthened digital traceability systems. The United States continues to press Mexico to reduce the profit margins associated with importing semi-finished products into the US through simple assembly processes. As a result, the risks associated with the temporary import system have increased, and customs clearance and storage costs have risen. Chinese enterprises operating in Mexico must increase their local value-added rates in order to qualify for the origin labeling provisions under the US-Mexico-Canada agreement. Mexico’s positioning towards Chinese enterprises is shifting from being merely a transit hub to becoming a manufacturing base for North America. Consequently, these enterprises will see a significant increase in capital expenditures.
Whether to take this path can be determined by a simple numerical criterion: whether the local value-added rate can reach the agreed threshold. If it cannot meet this requirement, then the investment in the Mexican local market becomes meaningless, as there will be no advantage from tariffs applicable to exports to the United States. In such cases, the significance of this investment needs to be re-evaluated.
IV. Channel 3: Completion of substantial processing in a third country to obtain the origin status
The third option is to utilize the existing free trade agreements between Mexico and economies such as the EU, the United States, and Canada. Substantive processing can be carried out in third countries that meet certain conditions, and products can then be imported into Mexico under the status of originating goods from those countries. The key factor isn’t logistics, but rather the rules regarding origin. Most agreements specify clear requirements regarding “substantial changes” in terms of tariff classification, regional value content, or specific processing steps. Simple assembly, dilution, or repackaging generally don’t qualify as substantial changes.
It is necessary to be aware of the level of enforcement in advance. The US Customs has implemented a new system for verifying the origin of goods, specifically designed to detect cases of goods being transferred or evading origin regulations. Mexico is also stepping up efforts to use digital traceability systems. The risk associated with relying on documents to determine the origin of goods is increasing rapidly. If such practices are identified as attempts to evade regulations, the consequences can include additional taxes and penalties.
V. Non-tariff Barriers: Certification, Labeling, and Local Import Qualifications
Tariffs are merely the first barrier. Mexico has a mandatory standard system for imported goods, requiring different compliance documents and Spanish-language labels for various categories of products. Additionally, local taxes and customs clearance qualifications are also required at the import stage. These procedures are usually handled by the importer or licensed customs agents. A common mistake factories make is to prepare all documentation in English or Chinese, only to find themselves forced to redo the labeling process during customs clearance. Goods stored in containers can cause delays at the port, with storage fees calculated on a daily basis.
Three practical matters to consider: create Spanish-language versions of product descriptions, label texts, and safety warnings, and conduct a trial production in the domestic market to ensure accuracy. Prepare testing reports and compliance statements for each target category, and confirm whether the issuing authority is recognized by Mexico. Also, clarify the details regarding the customs declaration entity, tax identification numbers, and payment methods with the importer, and include these details in the contract.
6. Common questions
When will the tariffs in Mexico expire? Will there be any extensions?
The current temporary tariffs are valid until December 31, 2026. It is also possible to extend their validity further. In August 2026, there were additional media reports regarding potential increases in restrictions on goods from countries not part of the free trade agreement. The focus remained on adding more restrictions and raising tax rates for such goods. However, at that time, the matter was still under government evaluation and negotiations with businesses, and no formal proposals were made. It is recommended that contracts with Mexican suppliers include provisions allowing for price adjustments, with tariff changes being considered as triggers for such adjustments.
2. Can using offshore companies or third-party agents help avoid paying taxes?
It is not recommended to design solutions that involve avoiding customs regulations. Tariffs are determined based on the country of origin, and the determination of origin relies on substantive processing rather than who issued the invoice or which account the funds were transferred to. Both the US and Mexico are strengthening their systems for verifying origin and implementing digital traceability. Those who attempt to circumvent these regulations will face the consequences of paying additional taxes and penalties. If one truly wants to use third-country channels, then it is necessary to ensure that the processing steps are genuine, so that the country of origin can be verified properly.
3. Small and medium-sized enterprises are not very large in scale. What should be done in the first step?
Just do one thing: compare each product according to the Mexican customs codes, and determine whether the products fall within the 10% to 15%, 20% to 35%, or 35% to 50% range. This step requires no additional costs and no cooperation from customers, but it determines the direction of all subsequent actions. For products that fall into the lower range, find local assembly partners. For those that fall into the higher range, assess whether the product’s form affects its brand reputation. For products that are regulated by authorities, prioritize addressing issues related to certification and labeling.
For factories that produce steel, chemical products, automotive components, textiles, and household appliances, the barriers in Mexico have shifted from being purely related to prices to issues related to origin and processing methods. It’s important to carefully calculate one’s tax categories and value-added rates before deciding whether to invest in local production capabilities or not.
