Brazil's INMETRO: Why Goods Sit at the Port

It usually goes like this: a distributor in São Paulo is selling your product well, and then a second container gets held at Santos for three weeks while customs keep asking for something called INMETRO.

Brazil has one of the strictest product certification regimes in the Americas, and it catches first-time exporters who assumed a CE mark or an FCC ID would be enough. It isn't. Here's how the system works and what to do about it before you ship.

What INMETRO is

INMETRO — the National Institute of Metrology, Quality and Technology — sets the rules for which products need mandatory certification before they can be imported and sold in Brazil. The certified product list is long: household electrical appliances, electronics and IT equipment, toys, some medical devices, helmets, solar equipment, automotive parts, and much more. If your category is on the list, there is no "voluntary" version of this. It's a precondition of entry.

The rule nobody tells you

The INMETRO certificate must be held by a legal entity established in Brazil. A foreign SME cannot hold its own certificate. This shapes your entire Brazil strategy: you either certify through your importer or distributor, or you appoint a local representative for the purpose.

Most small brands go the first route. Your distributor applies for certification with their name on the certificate, using your test data and their import licence. It works, and it's normal practice. But read that sentence again: the certificate is theirs. If the relationship sours, your product's market access goes with them. Some brands accept this, some negotiate co-ownership or a contractual right to the certification files, and a few bite the bullet and set up a Brazilian legal entity. There's no universally right answer; just don't discover the question after the breakup.

The process, realistically

  1. You pick an accredited certification body — known in Brazil as an OCP. The usual international names run Brazilian operations: UL, TÜV, Bureau Veritas, Intertek among them.
  2. Testing happens in INMETRO-accredited laboratories, most of them in Brazil. Some schemes accept foreign lab reports, but plan for testing in-country.
  3. The certifier runs a factory audit, issues the certificate, and registers it with INMETRO.
  4. Products get labelled in Portuguese, with the INMETRO seal and certification number, before import.

Count on three to six months and costs from the low four figures for simple products to significantly more for complex categories. Add the importer's licensing steps on top — importers of regulated products need an INMETRO import authorisation, and the paperwork runs in parallel with yours.

Toys, and the other mark people forget

Toys are their own trap. Brazilian toy certification follows ABNT NBR NM 300, based on ISO 8124, and the requirements around age grading, warnings in Portuguese and physical testing are enforced seriously. Customs inspectors open boxes.

And if your product has any radio function, you also need ANATEL homologation — Brazil's telecom regulator runs its own certification for RF devices, separate from INMETRO and separate from the electronics safety certification. A Bluetooth speaker needs both.

If you're a small company, start with the partner

The certification follows the importer relationship, so the importer is where you start. Before signing anything, ask for their current INMETRO certificates for similar products, ask who bears the certification cost (common answer: split, with the foreign brand paying testing and the importer paying their local fees), and get the timeline in writing. A partner who says "three weeks, no problem" is a partner who hasn't done this before. Real timelines are months, and professional importers know it and plan around it.

Then keep your side of the paperwork clean: model numbers that match between your invoices and the certificate, stable product specifications, and test reports you can hand over quickly when the certificate comes up for renewal. Brazilian certificates have fixed terms and post-market surveillance, and INMETRO does check the market, not just the border.

The exporters who do well in Brazil treat certification as a recurring relationship, not a one-time ticket. One product page that shows your INMETRO certificate, your safety data and your compliance history — live, dated, and verifiable by the customs broker and the retailer alike — saves your partner in Brazil from chasing you across time zones. Attach your partner's certificate to your product record in Sustalium (€10 per document, same model as every other market) and when it renews — or doesn't — you're notified before the shipment is booked, not after it's held. Brazil is hard enough. Don't make your partner fight you for paperwork too.

How Sustalium Helps with Brazil Market Entry

  • Partner-linked certificates — attach your importer's INMETRO certificate to your product record and get notified when it renews or lapses.
  • Portuguese-ready evidence — a live page your customs broker and retailer can both verify, without chasing you across time zones.
  • One record, many markets — the same product data that feeds INMETRO also feeds your CE, FCC and NOM work.

Don't Learn INMETRO at the Port of Santos

Keep the certificate live, linked to your partner, and verifiable by everyone in the chain. Start with a free draft and publish the verifiable version when you are ready.

Frequently Asked Questions

Can a foreign company hold its own INMETRO certificate?

No. The certificate must be held by a legal entity established in Brazil — in practice your importer, distributor or an appointed local representative.

How long does INMETRO certification take?

Plan for three to six months for most product families, plus the importer's own licensing steps running in parallel.

Does INMETRO cover telecom products?

No. Products with radio functions also need ANATEL homologation, which is a separate process from the safety certification.
