Why there is no such thing as GMP-certified extraction equipment

You’ve heard the sentence before. It comes about twenty minutes into a demo, after the solvent recovery numbers and before anyone has opened a drawing of your building, and it is never true: “This unit is GMP certified.” Sometimes the claim is “GMP-ready” instead, or “EU-GMP compliant,” which is something a machine cannot be. Sometimes it’s a small badge on the last slide. The stainless gleams, and everyone in the room wants the claim to be true, because if the machine were the certificate, you wouldn’t have to wrestle with a production room, a quality unit, or a Site Master File.

It is not true of Decimal’s machines or of anyone else’s, in the EU or under FDA, and a state cannabis license that uses the letters does not make it true. This essay is about GMP-washing: how the claim is put together, why buyers accept it, and the six boring questions that make it fall apart. There’s no skid for sale at the end of this piece; we’ll tell you what an inspector opens.

Greenwashing, in the environmental sense, is a label with no work behind it. GMP-washing is the same trick done in pharmaceutical vocabulary. Suppliers who do it use the letters because buyers of cannabis and hemp extracts have started to need them. The demand comes from a German importer, from a QP who will not otherwise release a batch, or from a board that heard “EU medical” in a pitch. On a website, the equipment looks the part, with product-contact steel, a tri-clamp, and a sentence about sanitary design. Often, that’s all the documentation there is.

GMP-washing works because the buyer is tired. They have already spent a year on HVAC, a year on a license, and a year being told that extraction is manufacturing, and they want one crate that settles the argument. A hollow GMP claim offers them that crate. The bill comes later: at IQ, when nobody can find a material certificate; at OQ, when a dead leg can’t be cleaned; and at the inspection, when the inspector doesn’t care what the brochure said.

The badge costs next to nothing, but the buyer pays heavily for a missing 3.1 certificate.

A GMP certificate is issued to a site. In the EU, it follows a competent-authority inspection of a manufacturing site. The US analog is not a sticker either: it’s a facility that has been inspected against 21 CFR 210 and 211, or against ICH Q7 for an API. The inspector walks the rooms, reads the SOPs, and asks who can stop a batch. They also look at whether the equipment in front of them can be cleaned, maintained, and qualified in that building, on that process.

Annex 15 is the EU text on qualification and validation. The IQ, OQ, and PQ belong to you, and they are not a PDF the OEM emails over with the serial number. A vendor can make qualification possible through the materials of construction, the surface finish, drainability, and a documentation package a third party can use. That’s a serious conversation to have, but none of it amounts to a certificate hanging on the skid.

Those citations are worth reading slowly if you sell equipment, or if you’re about to write a purchase order. The requirement for suitable design falls on you, the manufacturer of the medicine or the substance. The OEM is a supplier, and your quality unit still has to decide that the equipment is fit for purpose, which no supplier who is being straight with you can take off your plate.

None of these signs is a crime, but together they form a pattern. If three of them turn up in the same sales deck, you’re looking at a wash rather than a documentation package.

1. 01

   Calling the equipment certified

   The first sign is the phrase itself. Certificates go to sites, so there is no such thing as “GMP certified equipment.” If a supplier can’t settle for “designed to support a GMP process” and insists on “certified,” stop there. Ask who issued the certificate, to whom, on what date, and after which inspection, and watch how the room reacts.

2. 02

   Stainless steel as the whole argument

   Grade 304 or 316L tells you what the material is, and a material is not a contamination-control strategy. Product-contact steel is table stakes. What matters is the finish, the welds, dead legs, slope, whether a gasket can be pulled, and whether the system drains. “It’s stainless” is how you sell a tank to a brewery, and it’s no answer to Annex 7.

3. 03

   No mill certificates or heat numbers

   EN 10204 3.1 certificates on product-contact parts are unglamorous paperwork, and they are how you prove what the steel is when an inspector asks. If the vendor shrugs, or says “we can get that if the deal is big enough,” you’ve just been told that the documentation does not exist yet. You’ll be the one paying to create it.

4. 04

   Vague answers about dead legs

   Ask where the low points are and how a rinse gets out. Ask which connections were dummy-welded because someone didn’t want to machine a drain. A designer who has lived through swab testing will answer without reaching for a slide, and one who hasn’t will talk about the design being “sanitary-ish.”

5. 05

   IQ/OQ deferred to “phase two”

   Qualification protocols written against your process, in your room, with your utilities, are the substance of the job. A vendor who says “support available” but has no sample protocol, no recommended test points, and no list of the instruments that need calibration is selling you a crate now and an invoice later.

6. 06

   Badges and seals with no author

   Flags, seals, the words “meets GMP,” and PDFs with no revision history, no named engineer, and no drawing number all fall into this category. A document you wouldn’t accept in a batch record does not belong in a capex memo either.

You don’t need to be a QP to work through this list, but you do need to write the answers down and keep them. If a salesperson can’t sit still for the questions, that tells you something too.

• Which parts are product-contact, and what are their steel grade, surface finish (Ra), and weld standard? Which of those come with certificates you can have before the crate ships?
• How is it cleaned: in place, or by taking it apart? What doesn’t drain, and where will a swab fail first?
• What are the spare elastomers, and are they the same compound the drawing names?
• What does the IQ/OQ package contain? Ask for a table of contents, a sample, and the names of the people behind it, since “we help with that” does not answer the question.
• Was the design reviewed against a named text (EudraLex Vol 4, Annex 7, ICH Q7 §5, 21 CFR 211.63–68), or against “GMP” as an atmosphere?
• What happens when you change a pump? Change control is your system, but the vendor should still be able to tell you which drawings are affected.

A longer version of this list, written for equipment buyers, is on a sister site that we disclose below. The rule is the same there: without specific answers, you’re shopping for a label.

GMP-washing tends to blur jurisdictions together. “We do GMP” is pitched as though it covers a German importer, an FDA investigator, and a state cannabis inspector in one breath, and it does not.

For EU medicinal products, a competent authority inspects the site, and the equipment is part of the premises. Qualification falls under Annex 15, and the herbal specifics are in Annex 7. A Canadian or US domestic cannabis standard is not a substitute. If you’re trying to export an extract into that system as a starting material, a nicer centrifuge won’t close the gap. What’s missing is the documentation, the rooms, and a QP who will put their name on a batch.

In the US, 21 CFR 210/211 applies if you are in that system, and ICH Q7 applies if the fraction is an API. As a rule, FDA’s drug program does not inspect a state-licensed adult-use cannabis extraction lab, and a state walkthrough is a different thing from a six-systems inspection. Buying “GMP equipment” for a state license will not bring FDA in, and it does not replace the state’s oversight either.

The full comparison is on our page covering cGMP, EU GMP, and state cannabis rules. The short version is to work out which text you’re regulated under, then ask whether the machine can be qualified against it in your rooms.

GMPEquipment shares a house with Decimal Engineered Systems, which makes extraction equipment, and with Opsona, which makes software for regulated manufacturing. We disclose that on purpose, because the temptation in a shared house is exactly the wash this essay describes: using the education to launder a certificate onto a crate. We won’t give in to it.

Decimal can say that a machine was designed and documented to support an EU GMP facility, and that sentence has a specific meaning. It is not a certificate, though: it does not travel with the serial number, and it does not stand in for an inspection of your production room. If a claim on this site ever sounds stronger than that, it’s a mistake. Send it to hello@gmpequipment.com and we’ll cut it.

This essay backs up a shorter page that answers one question: Can equipment be GMP certified? The answer there is no. Our relationship with Decimal is set out in the Decimal disclosure.

What is GMP-washing?

GMP-washing is using the letters “GMP” with only the minimum behind them, usually stainless steel and a badge, so that a crate looks as if it has been inspected. The gaps won’t show on the website; they show up later, at qualification or in front of the authority.

How do I spot GMP-washing?

The supplier won’t talk about dead legs, mill certificates, surface finish, or a real IQ/OQ package. They’ll talk about the machine being certified instead, and that’s the moment to ask who certified it.

Does a domestic cannabis standard make a machine EU-GMP ready?

No, because the two set different bars for sanitary design, documentation, qualification, and traceability. For export, the problem to solve is the site, and a flag on the crate won’t change that.

Can any supplier sell me certified equipment?

No, and you should treat the offer as a warning sign. The strongest claim a supplier can truthfully make is that the equipment was designed and documented to support a certified facility, backed by documents you can read before you issue the PO.
