Small electrical appliances
Of all the mistakes possible in this category, the most basic and the most expensive is to manufacture with the wrong plug. Mexico uses type A and B; Brazil uses type N.
Respuesta rápida
What has to be checked before importing small electrical appliances from China?
Small electrical appliances for Mexico or Brazil require three decisions to be settled before production, and none of them is price. The first is the plug type: Mexico uses types A and B, and Brazil uses type N, which is exclusive to that country and cannot be replaced by an adapter on a product sold as a finished item. The second is mains voltage, 127 V in Mexico and 127/220 V in Brazil depending on the region, which forces the product to be bivolt or region-specific. The third is mandatory electrical certification, NOM in Mexico and Inmetro in Brazil.

The plug and the voltage: two mistakes that cannot be fixed
Mexico uses types A and B, the same as the United States, at 127 volts. Brazil uses type N, a three-round-pin standard exclusive to the country, and has both 127 and 220 volts depending on the region. A product manufactured with a European or Chinese plug cannot be sold in either market without replacing the cable, and if the cable is moulded to the appliance, replacement is not possible.
It is a mistake that happens because the factory produces by default for its own market or for Europe, and the importer does not specify it. It is caught at inspection, but by then everything is already produced. Specifying it before manufacturing costs nothing.
Electrical certification: not optional
Electrical appliances are the category with the heaviest regulatory control of all the ones we handle. In Mexico, a large part of the small appliance range falls within the scope of a NOM and cannot be imported without the certificate. In Brazil, Inmetro certification is mandatory for electrical goods and household appliances.
The practical problem is the lead time: obtaining the certificate requires laboratory testing on the finished product, and that can only be done after manufacturing. If it is not planned for, the certificate becomes the bottleneck of the whole project and the goods wait at the factory. Planning it from the design stage is the difference between launching on schedule and losing the season.
Where Shenzhen's advantage lies in this category
Small appliances are manufactured in several Chinese clusters: Shunde and Zhongshan for kitchen, Yueqing for electrical components, Ningbo for kitchen and personal-care appliances. Shenzhen is not the centre of this category.
Our advantage here is not geographic, it is one of control: certification, functional inspection and document management are the same in any category, and in an electrical appliance they are more demanding than in an accessory. We work the route that suits each product, even if the factory is outside Guangdong, and we will say so plainly instead of forcing sourcing from Shenzhen when it adds nothing.
Certifications and applicable regulation
Every product category has its own regime. This table summarises what each standard requires and what it is for; which one applies to your specific product depends on its classification, and we confirm that before production.
| Standard | What it covers and why it matters |
|---|---|
| NOM (México) | Mandatory for a large part of the electrical appliance and household appliance range. Before shipment. |
| Inmetro (Brasil) | Mandatory certification for electrical goods and household appliances. |
| IEC 60335 | Safety of household and similar electrical appliances. |
| CE / LVD / EMC | For the European market: electrical safety and electromagnetic compatibility. |
| RoHS / REACH | Restriction of substances in materials and coatings in contact with food. |
| Food grade | For parts in contact with food: verify the material, not the label. |
Frequently asked questions
Which plug do I need for Mexico and for Brazil?
Mexico uses types A and B, the same as the United States, at 127 V. Brazil uses type N, a three-round-pin standard exclusive to the country, and has both 127 V and 220 V depending on the region. The two are incompatible with each other and neither accepts a European or Chinese plug without an adapter, so the plug type has to be specified to the factory before production.
Do I need NOM certification for a household appliance?
For a large part of the small appliance range, yes. The applicable NOM depends on the specific category of the product, and the certificate must be obtained before shipment because the tests are carried out on the finished product. Checking the scope before manufacturing is essential: discovering it with the goods at the port forces the cargo to be held.
Does a 220 V appliance work in Mexico?
Not directly. The Mexican grid is 127 V in practically the whole country, so an appliance designed only for 220 V will not work, or will work badly. The solution is for the product to be bivolt, with a switched-mode power supply that accepts the full range, or to manufacture it specifically for 127 V. Brazil is more complex because it has both voltages depending on the region, and there the product must be bivolt or clearly labelled for the voltage it supports.
How do I verify that parts in contact with food are suitable?
By asking for the specific material and its food-grade certification, not the product label. At inspection, the declared material is checked against the specified one and the production line is checked for cross-contamination. A product that declares itself food-safe but is manufactured on a line that also processes industrial plastic is a serious problem.
