Why importing from China is still an edge for your brand
China is still the world's factory, and for a Mexican e-commerce brand, importing directly from the manufacturer can multiply your margin versus buying from a local reseller. The line between a business that survives and one that scales usually runs through cost of goods sold — and that's exactly where importing well pays off. But "importing well" isn't just landing a good FOB price: it's controlling the right Incoterm, moving the container along the most efficient route, clearing customs cleanly, and getting the product selling as fast as possible.
The good news: if you operate out of western Mexico, you have a concrete geographic advantage. The Port of Manzanillo is the most important on Mexico's Pacific coast and handles over half of the country's containerized cargo. It sits about 3 hours by road from Guadalajara, where a 3PL in Guadalajara can be waiting to receive, validate, and push your product into fulfillment. That proximity cuts days of inland transit and trucking cost versus importing through Gulf or central ports.
This is the practical, step-by-step guide — zero filler.
Step 1: Finding and vetting suppliers
The right supplier saves you problems no customs broker can fix later. The most common channels are Alibaba, Global Sources, and trade shows like the Canton Fair.
How to vet a supplier before you pay:
- Confirm it's a manufacturer, not a trading company — factory pricing is lower and quality control more direct. Ask for their business registration number and request real photos of the plant.
- Order paid samples before any large purchase order. A sample costs little; a container of defective product can break you.
- Negotiate a realistic MOQ (minimum order quantity). Many factories ask for 500-1,000 units; some flex on the first order.
- Hire a third-party inspection (firms like QIMA or SGS) to check the lot before it ships. It costs a few hundred dollars and is the best insurance there is.
- Structure payment to protect yourself: typically 30% deposit and 70% against a copy of the Bill of Lading or after inspection. Avoid paying 100% upfront to a new supplier.
Step 2: Understanding Incoterms (EXW vs FOB)
Incoterms define who pays for what and where the supplier's responsibility ends. The two you'll see almost every time:
- EXW (Ex Works): the supplier only makes the goods available at their factory. You pay for and coordinate EVERYTHING else: inland transport in China, export clearance, ocean freight, and customs in Mexico. Total control, but it demands a competent freight forwarder.
- FOB (Free On Board): the supplier delivers the goods loaded onto the vessel at the Chinese port of origin (e.g., FOB Shenzhen), including China's export clearance. You take on the ocean freight and everything that follows.
Why FOB is the e-commerce standard: with FOB the supplier handles the local logistics inside China — where you have no eyes and no contacts — and you take control from the port forward. It's the ideal balance of control and simplicity. Always request quotes as "FOB [Chinese port]" so you can compare suppliers apples to apples.
Step 3: Ocean freight to Manzanillo
Once the cargo is FOB, your freight forwarder books vessel space. Two modes:
- FCL (Full Container Load): an entire container (20' or 40') just for you. Worth it from roughly 15 m³ of cargo.
- LCL (Less than Container Load): you share a container with other importers. Ideal for small volumes, though the cost per m³ is higher and clearance can take longer.
Transit times to Manzanillo: transpacific routes from southern Chinese ports (Shenzhen, Ningbo, Shanghai) to Manzanillo typically run 18 to 30 days at sea, depending on stops and season. Add time for consolidation, documentation, and clearance. Plan with a realistic window of 5 to 7 weeks from the moment you pay to when the product is ready to sell.
The key document here is the Bill of Lading (B/L): the title of ownership for your cargo. Without it you can't release the container.
Step 4: Customs clearance at Manzanillo
This is where most first-time importers get stuck. In Mexico you cannot clear your goods on your own: the law requires a customs broker (agente aduanal) to sign and manage the clearance for you.
What you need in order:
- Importers' Registry (Padrón de Importadores): you must be registered with the SAT's Padrón de Importadores. Without it you can't import commercially. Some product categories also require enrollment in a specific-sector registry.
- Tariff classification (fracción arancelaria): every product is classified under an 8-10 digit code that determines how much duty you pay and which regulations apply (NOMs, permits, labeling). Misclassifying is the #1 cause of fines and delays.
- Pedimento: the official clearance document. Your customs broker prepares it, declaring the goods, their value, the tariff code, and the taxes paid. It's your legal proof of import.
The taxes you'll pay:
- IGI (General Import Duty): the tariff, which depends on the tariff classification. It can range from 0% (much product carries zero duty under trade agreements) up to 20-35% or more in certain categories like textiles or footwear.
- 16% VAT (IVA): calculated on customs value + IGI + other charges. It almost always applies.
- DTA (Customs Processing Fee) and other minor duties.
Important disclaimer: duties, taxes, and regulations vary by product and change over time. The figures here are indicative. Always consult your customs broker for the exact classification and calculation of your goods before committing to an order.

Step 5: From Manzanillo to Guadalajara
Once cleared, the cargo leaves the port. Here the western Mexico advantage shines: Manzanillo to Guadalajara is roughly 3 hours by road. Inland trucking (dry van or consolidated) delivers your goods to the warehouse the same day or the day after clearance.
Compare that to importing through Veracruz or a port far from your warehouse: extra days of inland transit, more handling, more cost. That's why a Guadalajara-based operation, with locations near the Pacific, squeezes the most value out of the route.
Step 6: Receiving into the 3PL and straight to fulfillment
The final leg is the one that turns goods into sales. When it arrives at the warehouse, your 3PL:
- Receives and counts against the packing list — catching shortages or damage immediately.
- Validates quality by sampling and reports any anomalies.
- Logs the inventory in the WMS, with traceability by SKU and lot.
- Slots the product into picking locations.
- Activates the inventory so your stores (Shopify, Amazon, Mercado Libre, TikTok Shop) can sell it.
From there, fulfillment takes over: each order is picked, packed, and shipped without you touching a box. Importing and selling become a single connected chain.
Common mistakes that cost you dearly
- Paying 100% upfront to a supplier with no track record. Structure the payment and require inspection.
- Classifying the tariff code yourself. One mistake changes the duty and can trigger fines. Leave it to your customs broker.
- Not being in the Importers' Registry before the container arrives. The paperwork takes time; do it weeks in advance.
- Ignoring NOMs and labeling. Many products require Spanish labeling or compliance with a NOM before they can enter. Without it, your cargo gets held.
- Undervaluing the goods to pay less tax. It's illegal, it gets caught, and the penalties are severe.
- Not planning cash flow. You pay for goods, freight, and taxes weeks before you collect on the first sale.
Frequently asked questions
How long does it take to import from China to Mexico?
Realistically, 5 to 7 weeks from when you pay to when the product is ready to sell: this includes production/prep, 18-30 days at sea to Manzanillo, customs clearance, and inland transport. Peak season (before Chinese New Year and Mexico's Buen Fin) can stretch the timelines.
Do I need a registered company to import?
Yes. To import commercially you need an RFC (tax ID) and enrollment in the SAT's Importers' Registry (Padrón de Importadores). Individuals with business activity can also register. Your customs broker guides you through the process.
FOB or EXW for my first import?
FOB, almost always. It leaves the logistics inside China — where you have no direct control — in the supplier's hands, and gives you the reins from the port of origin. EXW only makes sense if you already have a strong freight forwarder and want total control.
How much will I pay in taxes?
It depends on the tariff classification. As a reference: IGI (from 0% up to 20-35%+ depending on the product) plus 16% VAT on the customs value. Much product carries zero duty under trade agreements. Only your customs broker can give you the exact calculation for your goods.
