Mexico offers some of the most powerful legal tools available anywhere in the world to reduce import duty Mexico, but most foreign businesses importing into or through Mexico are not using them. The IMMEX programme eliminates import duty and VAT on production inputs for qualifying manufacturers. PROSEC reduces tariff rates on specific industrial sectors. USMCA eliminates tariffs entirely on qualifying goods between Mexico, the US, and Canada. Yet the majority of importers entering Mexico pay standard rates because they have never been told these tools exist or because they assumed they did not qualify. This guide covers every mechanism available, who qualifies, and what the saving looks like in real numbers for importers operating in Mexico.

Why Import Duty in Mexico Is Higher Than It Needs to Be
Mexico’s standard import tariff rates are moderate by global standards, ranging from 0% to 25% on most goods, with a weighted average of around 6.5%. The problem is not the rate alone. It is what sits on top of it. A standard commercial import into Mexico triggers customs duty, plus 16% Value Added Tax (IVA) on the landed value, plus in some cases countervailing duties on goods from countries Mexico has found to be dumping products below market price. Combined, these charges can push the total tax burden on a standard import to 30-40% of the goods value before the goods have touched Mexican soil.
The second problem is that most importers entering Mexico for the first time are unaware that the country operates one of the most sophisticated duty reduction frameworks in the world. IMMEX, PROSEC, free zones, and USMCA together create a legal architecture where qualifying businesses can eliminate the vast majority of their import duty and IVA exposure.
Critical 2026 update: Mexico’s January 1, 2026 Customs Law Reform introduced three significant changes that affect every importer:
- Import tariffs raised on 1,463 tariff codes, approximately 12% of the entire tariff schedule, with new rates averaging 35% and reaching 50% in textiles, apparel, plastics, steel, aluminium, and automotive parts
- Mandatory digital traceability and real-time inventory monitoring for IMMEX companies, replacing the previous periodic audit model
- Expanded penalties for non-compliance, including fines of 250-300% of commercial value on prohibited imports and potential revocation of IMMEX certification
If your goods fall in any of the affected categories, reviewing your duty reduction options is no longer optional.
How to Reduce Import Duty Mexico: The Four Programmes That Work
1. IMMEX: Eliminate Duty and IVA on Production Inputs
The IMMEX programme (formerly the maquiladora programme) is the most valuable duty reduction tool available in Mexico for manufacturers. A company certified under IMMEX can import raw materials, components, machinery, and equipment duty-free and IVA-free, provided those inputs are used to manufacture or assemble goods that will be exported. The certification is granted by the Mexican Secretariat of Economy and requires annual renewal with export activity reporting. Programme statistics and active registrations are published by INEGI, Mexico’s National Institute of Statistics and Geography. IMMEX covers the following import categories duty-free:
- Raw materials and components used in the manufacturing process
- Machinery and equipment used in production
- Packaging materials for the exported product
- Fuel and lubricants used directly in production
The duty and IVA exemption applies only while goods are within the IMMEX process. Understanding what IMMEX actually covers is important because many applicants assume it eliminates all taxes automatically:
- IMMEX alone suspends the General Import Duty (IGI) on temporarily imported goods
- To eliminate the 16% IVA at import, a company must additionally obtain a VAT and IEPS Certification (CIVAM) from Mexico’s Tax Administration Service (SAT)
- Most established IMMEX manufacturers hold both: the IMMEX certification and the CIVAM, to achieve full duty and IVA suspension
If goods are diverted to the Mexican domestic market without the correct change-of-regime procedure, full duties and IVA become payable immediately plus penalties. For mixed domestic and export operations, IMMEX applies to the proportion of inputs that flow into exported goods. Our guide to Mexico customs rules for high-value imports covers the IMMEX application process in detail.
2026 IMMEX restriction to note: Finished textiles and apparel (HS Chapters 61, 62, and 63) are now prohibited from temporary importation under IMMEX following restrictions introduced in late 2024. Businesses in these categories need PROSEC or alternative duty relief structures.
2. PROSEC: Reduce Duty on Specific Industrial Sectors
The PROSEC programme (Programmes for the Promotion of Specific Sectors) allows businesses in designated industrial sectors to import specific inputs at reduced preferential tariff rates, regardless of whether those goods will be exported. Unlike IMMEX, PROSEC does not require export commitment. It currently covers 22 designated sectors including:
- Electronics and telecommunications
- Automotive and auto parts
- Textiles and footwear
- Furniture and wood products
- Agricultural equipment
- Medical devices and pharmaceuticals
PROSEC rates on qualifying inputs typically range from 0% to 5%, against standard MFN rates that can reach 20-25% on the same products. For manufacturers sourcing components from outside USMCA partner countries, PROSEC can produce a tariff reduction of 15-20 percentage points on qualifying inputs without any export obligation.
3. USMCA: Zero Tariffs on Qualifying North American Goods
The United States-Mexico-Canada Agreement (USMCA) eliminates tariffs on goods that genuinely originate within the North American trade area and meet the applicable rules of origin. For most product categories, qualifying goods move between Mexico, the US, and Canada at zero duty. The automotive sector has the strictest requirements:
- 75% regional value content from North American materials and labour
- Specific steel and aluminium sourcing thresholds from US or Mexican sources
- Labour value content of at least 40-45% of production at wages above $16/hour
For non-automotive goods, rules of origin are generally more straightforward. USMCA preferential treatment must be actively claimed at the border with a USMCA Certification of Origin. Importers paying full tariffs on Mexico-origin goods entering the US or on US-origin goods entering Mexico who have never checked USMCA eligibility are almost certainly overpaying.
4. Mexico Free Zones and Bonded Warehouses
Mexico operates special economic zones and bonded warehouse facilities where goods can be stored without immediate duty payment. Goods in a bonded warehouse have not entered Mexican customs territory. Duty and IVA are suspended until goods leave the warehouse for domestic consumption. If goods are re-exported from the bonded facility to a third country, no Mexican duty or IVA is ever paid. For businesses using Mexico as a regional distribution hub for Latin America, this structure converts a large upfront duty payment into a variable cost triggered only at the point of domestic sale.
Real Example: What a Mexico Importer Saved
A US electronics manufacturer setting up a PCB assembly operation in Monterrey, Mexico for export back to the United States and Europe. Annual import of components from China into Mexico: $3.2 million.
| Without IMMEX | With IMMEX | |
|---|---|---|
| Import duty (12% avg on Chinese components) | $384,000 | $0 (suspended) |
| IVA at 16% | $563,000 | $0 (suspended with CIVAM) |
| Total annual tax burden | $947,000 | $0 |
| IMMEX setup and compliance cost | N/A | $23,000 (year one) |
| Net saving | $924,000 in year one |
What Most Importers Get Wrong When Importing Into Mexico
Two mistakes account for most of the unnecessary duty cost paid by businesses importing into Mexico:
- Assuming IMMEX is only for large manufacturers. The programme is available to businesses of all sizes provided they meet the minimum export threshold: $500,000 USD in annual export value or 10% of total invoiced sales. Many mid-sized manufacturers importing into Mexico for mixed domestic and export production qualify but have never applied. For mixed operations, IMMEX applies to the proportion of inputs that flow into exported goods, not just fully export-dedicated production.
- Failing to claim USMCA preferential rates. Thousands of importers bringing US or Canadian-origin goods into Mexico pay full Mexican MFN tariffs because their USMCA Certification of Origin was not prepared correctly or was missing entirely. A missing certification on a $500,000 shipment of US-origin industrial goods at a 10% MFN rate is $50,000 paid unnecessarily on a single shipment.

Frequently Asked Questions: Reduce Import Duty Mexico
Who qualifies for IMMEX in Mexico?
Any company with a legal presence in Mexico that manufactures, assembles, or processes goods for export can apply for IMMEX certification from Mexico’s Secretariat of Economy. The minimum qualification threshold is either $500,000 USD in annual export invoicing or exports representing at least 10% of total annual sales. The company must also demonstrate that imported inputs will be used in the production of the exported goods. Businesses that manufacture in Mexico for a mixed domestic and export market qualify for IMMEX on the proportion of inputs that go into exported goods, not just on fully export-dedicated operations.
What is the difference between IMMEX and PROSEC?
IMMEX eliminates duty and IVA entirely on imported inputs but requires that those inputs be used in goods that are exported. PROSEC reduces the duty rate on imported inputs for businesses in designated industrial sectors but does not require export. IMMEX delivers a larger saving but only for exporters. PROSEC delivers a partial saving and is available to manufacturers supplying the Mexican domestic market. The two programmes are not mutually exclusive. Many businesses in designated sectors hold both certifications and apply whichever delivers the greater saving on each specific import.
How does USMCA reduce import duty when importing into Mexico?
USMCA eliminates tariffs on goods that genuinely originate in the United States or Canada and meet the applicable rules of origin for their product category. To claim the preferential rate, you must provide a USMCA Certification of Origin at the Mexican border. Your US or Canadian supplier must confirm the goods meet the regional value content and tariff shift requirements for the applicable HS code. The certification can be prepared by the exporter, the importer, or a qualified trade compliance specialist. It does not need to be a government-issued document. A correctly completed commercial invoice statement is sufficient for most product categories.
Do I need a Mexican legal entity to use IMMEX?
Yes. IMMEX certification is granted to a legal entity registered in Mexico with the Secretariat of Economy. A foreign company cannot hold an IMMEX certification directly. However, a specialist Importer of Record with an established Mexican legal entity and existing IMMEX certification can import goods on your behalf under that certification, giving your business access to IMMEX duty and IVA savings without the cost and time of setting up your own Mexican entity. This is the route used by most foreign businesses entering Mexico for the first time or for smaller-scale manufacturing operations.
What happens if IMMEX goods are sold into the Mexican domestic market?
Goods imported under IMMEX that are diverted to the Mexican domestic market without completing the correct change-of-regime procedure trigger immediate consequences:
- Full duty and IVA payable immediately on all goods diverted, plus surcharges
- Financial penalties of up to 250-300% of the goods’ commercial value under the 2026 Customs Law Reform
- Potential cancellation of the IMMEX certification, ending the programme benefits for the entire operation
The change-of-regime procedure allows an IMMEX company to legally transfer goods to domestic consumption by paying the applicable duty and IVA at the time of transfer through the Mexican customs authority. Businesses that need to sell a portion of IMMEX-imported goods domestically should use this procedure rather than diverting goods informally.
Can a foreign company with no Mexico presence reduce import duty on goods shipped through Mexico?
Yes, through two routes. The first is using a bonded warehouse in Mexico to store goods in transit to other Latin American markets without triggering Mexican duty or IVA, provided goods are re-exported without entering Mexican customs territory. The second is working with a specialist Importer of Record that holds existing IMMEX or PROSEC certifications and can import on your behalf under those frameworks. Both routes give a foreign business access to Mexico’s duty reduction architecture without establishing a local legal entity. The bonded warehouse route works for transit and distribution. The IOR route works for businesses using Mexico as a manufacturing or processing location.
