Understanding Mexico Customs in 2026
Shipping across the border from the USA to Mexico involves more than just putting an item in a box. Mexican customs (Aduanas) maintains strict regulations to ensure safety and fair trade. Whether you are a frequent shopper or a first-time sender, using a reliable package forwarder like comGateway can help you navigate these hurdles effortlessly.
Prohibited Items (The Never-Allowed List)
Some items are strictly forbidden from entering Mexico. Attempting to ship these will likely result in the package being seized or returned at the sender's expense. As of 2026, the following items are prohibited:
- Used Clothing and Footwear: Unless classified as personal effects in luggage, used clothes are generally restricted to protect the local textile industry.
- Narcotics and Illegal Drugs: This includes all forms of cannabis, even if legal in the US state of origin.
- Weapons and Ammunition: This includes firearm parts, tactical gear, and even some high-powered airsoft guns.
- Used Tires: These are strictly banned for environmental and safety reasons.
- Combustible Materials: Any items that are flammable, explosive, or corrosive.
Restricted Goods Requiring Special Permits
Restricted goods are different from prohibited ones; they can be shipped, but they require specific documentation or health certificates. If you have common questions about a specific product, it is always wise to check our FAQ before placing your order.
- Health Supplements and Vitamins: Often require a permit from COFEPRIS (Mexico's health authority) if shipped in large quantities.
- Cosmetics and Beauty Products: Generally allowed for personal use, but bulk shipments may be flagged as commercial.
- Electronics with Dual-Use: High-end drones or specialized encryption hardware may require additional clearance.
- Wood Products: Items made of raw wood must be treated and certified to prevent pest infestation.
Size and Weight Limits for 2026
When shipping from USA to Mexico, carriers like DHL, FedEx, and UPS have specific physical constraints. While these vary slightly by service, the general cheat sheet for standard shipments is as follows:
| Limit Type | Standard Threshold |
|---|---|
| Maximum Weight | 70 kg (approx. 154 lbs) per package for express services |
| Maximum Length | 274 cm (approx. 108 inches) |
| Girth Limit | Length + 2x Width + 2x Height should not exceed 400 cm |
Exceeding these limits often results in "Oversize" surcharges. To avoid unexpected fees, you should always estimate shipping costs to Mexico using a volumetric weight calculator before finalizing your shipment.
Taxes, Duties, and the De Minimis Threshold
Mexico's import tax structure is vital for budgeting. Under the current trade agreements in 2026, the following thresholds apply to most consumer goods:
- Under $50 USD: Generally exempt from both duty and IVA (Value Added Tax).
- $50 USD to $117 USD: Exempt from customs duties but subject to IVA (typically 16%).
- Over $117 USD: Subject to both applicable customs duties and IVA.
Keep in mind that these values include the cost of the item plus shipping and insurance. To get the most accurate financial picture, always check the latest shipping rates and tax calculators provided by your forwarder.
Final Tips for a Smooth Shipment
To ensure your package clears customs without delay, always provide a detailed commercial invoice. Avoid vague descriptions like "Gift" or "Merchandise." Instead, use specific terms like "Cotton Men's T-shirt" or "Stainless Steel Kitchen Knife."
