Import tax in Mexico applies to goods brought into the country and is designed to protect local industry, generate revenue, and regulate trade. Understanding how these duties, taxes, and fees are calculated helps importers avoid delays and unexpected costs at the border.
Below is a structured overview of import tax in Mexico, including who pays, main tax rates, key exemptions, and typical processing timelines.

| Applicable Taxes | Import VAT (16%), Customs Duty (0–15%), SAT Regulatory Fees | Duty rates vary by HS code and origin |
| Who is Responsible | Importer of Record, typically the customs broker | Buyer and seller may agree on Incoterms, but the legal importer pays |
| Key Exemptions | Temporary imports, diplomatic cargo, some medical equipment | Requires prior SAT authorization in many cases |
| Estimated Processing Time | 3–7 business days for release if documents are complete | Can extend to weeks if audit or verification is triggered |
| Main Regulatory Body | SAT (Tax Administration Service) | SECOFI manages trade policy; customs brokers must be licensed |
Understanding Mexican Customs Duties and Classification
Mexican customs duties are applied based on the Harmonized System (HS) code assigned to each product. The HS code determines the customs duty rate, which can range from 0 percent to over 15 percent depending on the product category and country of origin. Each product is also classified for VAT purposes, and the combined effect of customs duty, VAT, and any additional fees defines the total landed cost.
Importers must declare the correct HS code on the Pedimento de Importación. An incorrect code can lead to underpayment of duties, penalties, or prolonged clearance. SAT relies on brokers and customs agents to validate classifications, so professional guidance is strongly recommended for complex or high-value shipments.
Origin-based preferential rates under trade agreements such as the United States–Mexico–Canada Agreement (USMCA) can substantially lower or eliminate duties on eligible goods. Proper certification and documentation are required to claim these benefits, and not all products qualify automatically.
Key Import Tax Rates and Product Categories
Different product categories are subject to different tax structures in Mexico. Electronics, automotive parts, textiles, and agricultural goods all have distinct duty schedules. It is important to verify the specific HS code for your item to determine the exact rate and any additional requirements.
| HS Code Range | Product Category | Customs Duty Rate | VAT Rate |
|---|---|---|---|
| 8471 | Laptops and Computers | 0% under USMCA | 16% |
| 8517 | Mobile Phones | 0% under USMCA | 16% |
| 6109 | T-shirts and Apparel | 5–10% | 16% |
| 1004 | Sugarcane and Related Products | 0–15% depending on quota | 16% |
| 8703 | Passenger Vehicles | 5–20% based on engine and origin | 16% |
How Value, Insurance, and Freight Affect Tax Calculations
The taxable base for import duties and VAT in Mexico is typically the transaction value, which includes the price of goods, freight, and insurance up to the Mexican border. Customs authorities assess these components to determine the total amount subject to tariffs and VAT. Shipment terms such as CIF or DDP influence how these costs are allocated and reported.
Insurance and freight costs must be properly documented and reflected in the customs declaration. If these elements are understated, SAT may adjust the taxable base based on similar transactions or market data. Accurate invoicing and bill of lading information reduce the risk of adjustments or disputes.
Working with a reliable customs broker ensures that freight, insurance, and value are reported consistently. This alignment minimizes audits, accelerates release, and supports better cash flow planning for importers bringing goods into Mexico.
Compliance Requirements and Documentation for Importers
Importers operating in Mexico must follow strict documentation and compliance procedures. Core documents include the commercial invoice, packing list, bill of lading or air waybill, certificate of origin, and any required permits. Electronic filing through the SAT portal is mandatory, and each submission must match physical inspections when requested.
A Pedimento de Importación is generated by the customs agency once duties and taxes are paid. This document serves as proof of legal entry and is required for downstream processes such as warehousing, distribution, or manufacturing. Brokers usually handle filing, but the importer retains ultimate responsibility for accuracy.
Penalties for late payment, misclassification, or non-compliance can include fines, temporary seizure of goods, and suspension of import privileges. Establishing robust internal controls, periodic audits, and professional guidance helps importers maintain compliance and avoid costly disruptions.

FAQ
Reader questions
How is the import tax base calculated for shipments arriving in Mexico?
The taxable base includes the transaction value of the goods, freight charges to the Mexican destination, and insurance up to the border. SAT reviews this combined value to assess customs duties and VAT, so accurate cost breakdowns are essential.
Can I import machinery from the United States into Mexico without paying duties under USMCA?
Many machinery and equipment items may qualify for zero customs duty under USMCA, but strict rules of origin and certification apply. Proper documentation and correct HS coding are required to claim these preferential rates.
What happens if the HS code on my import declaration is incorrect?
An incorrect HS code can lead to underpayment of duties, penalties, customs delays, or even seizure of goods. SAT may reassess taxes based on the correct classification, so it is important to verify codes with a qualified broker or expert.
Are there exemptions from import tax for medical or humanitarian shipments into Mexico?
Certain medical equipment and humanitarian aid may be exempt from import duties, but importers must obtain prior authorization from SAT and provide detailed documentation. These exemptions are applied on a case-by-case basis and often require specialized permits.
