“Not for human consumption” on a kratom packet is a legal statement, not a safety one. It exists because of how food law is written. In most of Europe, and in a different way in the United States, kratom cannot lawfully be sold as something to eat or drink. A seller who prints those words is saying, in effect, that the product is not food, so the rules for food do not apply to it.
That is the whole job the label does. It is not a warning that the contents are dangerous, and it is not a promise that they are safe. It does not tell you whether you may lawfully hold the product where you are. Read it as information about the seller’s legal position, because that is all it carries.
Why the label exists
Start with what European law counts as food. The EU’s General Food Law, Regulation 178/2002, defines it in Article 2 as “any substance or product, whether processed, partially processed or unprocessed, intended to be, or reasonably expected to be ingested by humans”.
Then add the novel food regulation, Regulation 2015/2283. A novel food is one that was not used for human consumption to a significant degree in the EU before 15 May 1997, and plants and their parts are one of the categories it covers. Article 6 then says that only novel foods authorised and included in the Union list may be placed on the market. Kratom has never been authorised, which is why our European Union page describes it as an unauthorised novel food.
Put the two together and the label’s purpose is plain. If kratom is sold as food, it is an unauthorised novel food and the sale is unlawful. So sellers present it as something other than food: a botanical specimen, incense, a sample for analysis, or simply “not for human consumption”.
Whether the label works is not up to the seller
Look again at the Article 2 definition. A product is food if it is intended to be ingested or if it is “reasonably expected to be” ingested. A label can say something about the seller’s stated intention. It cannot, on its own, change what can reasonably be expected to happen to a powder sold in 50 gram pouches by a shop whose product pages describe effects.
That second limb is why the label is a claim rather than a settled answer. Whether a particular product is food is decided by the authorities who enforce food law, looking at the product and how it is sold, not by the words the seller chose. We are not going to tell you how a given regulator would decide a given product, because that turns on facts we do not have.
What the research does show is how the label sits beside the rest of the selling. A 2025 study in the Harm Reduction Journal examined 25 online shops selling kratom to Hungary, including sellers based in Hungary, the Czech Republic, Slovakia and the Netherlands. Twenty of the 25 carried disclaimers on their websites. Of those 20, 16 said the product was sold for “botanical” or “analytical purposes” and 15 said it was “not suitable for human consumption”. In the same sample, 17 of the 25 shops promoted the product’s effects, and only 8 gave any information on possible adverse effects. The authors describe the disclaimers as appearing to serve “as a legal shield to minimize liability rather than a genuine effort for promoting harm reduction”.
That study is a survey of shop websites and a small set of test purchases, which is the second tier of evidence on our scale. It describes one regional market at one point in time. It does not tell you how every seller behaves.
Some laws do not ask what the label says
Food law is not the only law that applies, and some offences are written without reference to labelling at all.
In the United Kingdom, kratom falls under the Psychoactive Substances Act 2016, which our United Kingdom page covers. Section 5 makes it an offence to supply a psychoactive substance where the supplier knows, or is reckless as to whether, it is likely to be consumed “for its psychoactive effects”. The test is whether the supplier knows, or is reckless about, what is likely to happen to the substance. The Act does not mention labels. Whether a supplier knew or was reckless is decided on the evidence, and we are not going to predict how a court would weigh a label in a given case. Section 2 defines consuming broadly, as causing or allowing a substance to enter the body “in any way”.
In the United States, the federal definition of food in the Food, Drug, and Cosmetic Act covers “articles used for food or drink for man or other animals”. It describes what an article is used for and says nothing about labels. How the Food and Drug Administration and the courts decide what an article is used for is a body of case law we have not read for this guide. Our United States page sets out the federal position on kratom itself.
What the label means for you
It does not mean anyone checked the product as a food. A seller who says the product is not food is, by its own account, not offering it under the rules that govern food, such as the EU’s limits on contaminants. Whether an authority would agree with the seller is a separate question. Our guide to reading a heavy metal test explains which limits exist and why none of them was written for kratom.
It does not tell you what is in the packet. The 2025 study’s disclaimer figures describe shop websites. When the researchers looked at the 10 products actually delivered, only 4 carried substantive information about their contents, the distributor and storage, together with a warning against human consumption. The other six carried little or none.
It is not a statement about whether you may hold it. In countries where kratom is a controlled substance, such as France, Romania or Sweden, the label changes nothing about possession or import. Our legal status pages cover each country we have read.
It is not the only way a market can work. The Czech Republic took a different route. Since late 2025 kratom there is a regulated psychomodulatory substance, and the decree that governs it requires the opposite of a disclaimer: each package must carry consumer information, the contents are capped, and the label may not state a recommended dose above limits the decree sets. Our Czech Republic page describes the regime.
What none of this settles
This guide explains what the label is for. It does not decide whether a particular product, sold in a particular way, is food in law, and it does not tell you whether kratom is safe to take. The evidence on that is thin and contested, and a label written to keep a product outside food law was never going to answer it.
