Ensuring quality, radical transparency, and trust in the cannabis market
ECCO exists to protect human health through science-backed certification. We certify brands that exceed exceptional standards and give people confidence in what they consume.
Our vision: clean, verified products for people who care about what goes into their body. Because knowing what you consume shouldn't be a luxury.

Most consumers have no idea what contaminants might be in their products. Pesticides, heavy metals, residual solvents — without proper testing, you're left guessing. That's a health risk.
We put products through rigorous, independent testing so you don't have to guess. When you see the ECCO seal, you know it's been verified for safety, quality, and environmental responsibility.

Ready to prove your products are the real deal? Start by telling us about your brand and what you're bringing to the table.
We take a close look to make sure your brand aligns with our standards. Think of it as the first handshake.
This is where the science kicks in. Independent labs put your products through rigorous testing — the same way a consumer would use them.
Our certification committee reviews everything and makes the call. No shortcuts, no exceptions — just the data.
You made it. Your products earn the ECCO seal — a signal to consumers that what they're getting is clean, safe, and verified.
Certification isn't a one-and-done deal. We keep checking to make sure your products stay up to standard.
Every year, we run it back. Standards evolve, and so should your products. That's how trust is maintained.

Knowledge is power — especially when it comes to cannabis. We break down the science, the standards, and the stuff that actually matters so you can make informed choices.
Dive InFrom cultivators to scientists, retailers to regulators — it takes a whole ecosystem to set the standard for cannabis. Meet the people driving the mission forward.
