How to Prepare Your Shipment to Comply with Customs Mexico Regulations

Step-by-step tips for exporters and importers to avoid delays and costly mistakes

Shipping goods to Mexico offers exciting business opportunities—but navigating customs Mexico regulations can be complex without the right guidance. Whether you’re a seasoned exporter or shipping south of the border for the first time, proper preparation is critical to avoid delays, penalties, or shipment seizures.

At Baum Shipping, we help clients simplify international logistics every day. Below, we break down how to prepare your cargo to ensure full compliance with customs Mexico regulations, from documentation to packaging standards.

Step 1: Understand What You’re Shipping

Before you even pack a box, review the tariff classification and regulatory status of your product under Mexico’s Harmonized Tariff Schedule (HTS). Certain items—such as electronics, pharmaceuticals, food, textiles, and chemicals—may be subject to:

Import permits or sanitary regulations
Labeling in Spanish
NOM (Normas Oficiales Mexicanas) certification
Environmental or safety standards

Tip: If you’re unsure, consult a licensed customs broker or logistics provider like Baum Shipping to verify product restrictions before shipping.

Step 2: Gather the Required Documentation

Documentation is the heart of customs Mexico regulations. Even a single missing form can hold up your entire shipment.

Essential shipping documents include:

Commercial Invoice – Must list the shipper and consignee, detailed item descriptions, HS codes, quantity, unit value, and total cost.
Packing List – Itemizes goods in each container or pallet.
Bill of Lading – Proof of carriage between the shipper and carrier.
Certificate of Origin – Especially important for reduced tariffs under USMCA.
Import Permits or NOM Certificates – If applicable based on product type.
Mexican Tax ID (RFC) – The importer in Mexico must provide their Registro Federal de Contribuyentes number.

Pro Tip: Make sure documents are consistent across all forms—discrepancies can trigger red flags during customs clearance.

Step 3: Label and Package According to Standards

Mexico enforces strict packaging and labeling requirements, particularly for consumer goods.

Labeling must include:

Spanish-language content
Product name and description
Country of origin
Importer name and address in Mexico
Relevant NOM compliance symbols (if required)

Packaging standards:

Use sturdy, tamper-proof materials
Avoid untreated wooden pallets (must meet ISPM-15 standards)
Clearly mark fragile or hazardous items
Ensure accurate weight and dimensions

Proper labeling and packaging not only ensure regulatory compliance but also protect your cargo from damage or inspection delays.

Step 4: Coordinate with a Licensed Customs Broker

A Mexican customs broker is essential for formal entry into Mexico. This licensed professional files documentation with Aduanas (Mexican Customs) and coordinates with the importer on your behalf.

At Baum Shipping, we work directly with vetted brokers in Mexico to ensure seamless cargo clearance, including pre-clearance checks, duty calculations, and real-time tracking.

Step 5: Verify Duties and Taxes

Mexico applies ad valorem import duties, Value Added Tax (IVA), and sometimes special fees depending on the product category. Most duties are calculated based on CIF value (Cost + Insurance + Freight).

Your customs broker or freight forwarder should provide:

Estimated import duty
IVA (typically 16%)
Customs processing fees
Any applicable countervailing duties or trade agreement exemptions

Baum Shipping helps clients optimize their shipping routes and reduce costs by identifying duty-saving strategies and exemptions.

Step 6: Track, Inspect, and Respond Quickly

Once your shipment arrives, be prepared for random inspections or document verifications. Delays can occur if customs finds inconsistencies or non-compliant packaging.

To reduce risk:

Double-check documentation before shipping
Share shipment tracking and customs info with your consignee in Mexico
Work with a team like Baum Shipping who can troubleshoot in real time
