A lab certificate, also known as a COA or Certificate of Analysis, is the analysis report from an independent laboratory for a specific batch of CBD flower. It shows which cannabinoids were measured and in what concentration, above all the THC content and the CBD content, and links these values to a product unambiguously via the batch number. CBDÍA publishes such a certificate for every batch, because it's the only way you can check whether the information on the product page matches what is actually in the bag.
A lab certificate for CBD flower almost always follows the same structure. Once you know the following information, you can make sense of any COA within a few minutes, no matter which supplier it comes from.
| Information | What it means | What to look out for |
|---|---|---|
| Batch number | The identifier of the production unit the sample comes from. This number links the certificate to a specific quantity of flower. | The number on the certificate must match the number on the packaging or the product page. |
| Test date | The day the lab analysed the sample. | The date should match the batch. A certificate that is significantly older than the batch belongs to a different harvest. |
| THC content | The proportion of delta-9-THC, usually stated as total THC including the acid form THCA. | For hemp, the value is below the limit of 0.3 percent. Check whether total THC or only delta-9-THC is stated. |
| CBD content | The proportion of cannabidiol, also often stated as total CBD including CBDA. | The measured value should match the figure on the product page or fall within the range stated there. |
| Other cannabinoids | Minor cannabinoids such as CBG, CBC or CBN, which occur in smaller amounts depending on the strain. | These values show how thoroughly the lab measured. If only CBD and THC are listed, the profile is incomplete. |
| Terpene profile | The aroma compounds of the flower, such as myrcene, limonene or caryophyllene, if the lab determined them. | A terpene profile is optional, but helps when comparing strains and proves the flower hasn't gone stale. |
| Laboratory | Name and address of the laboratory that carried out the analysis. | The laboratory should be independent of the seller. If the lab name is missing entirely, the document isn't a certificate, but a self-declaration. |
CBD flower sold in Germany comes from hemp. Hemp is defined as cannabis grown from certified seed of strains listed in the EU variety catalogue, or with a maximum of 0.3 percent THC, in each case only for commercial or scientific purposes without misuse for intoxication (§ 1 No. 9 KCanG, the German Consumer Cannabis Act). CBDÍA flower meets both criteria. The lab certificate is the proof that a specific batch stays within this value. The strain name alone isn't enough, because THC content fluctuates depending on cultivation, harvest and storage.
That's why you first look at the THC line in the certificate. If the value there is below 0.3 percent and the batch number matches the product, the most important question is answered. If the value is higher or the figure is missing, you shouldn't buy the product. This classification is not legal advice, and the legal situation can change. As of: September 2026.
A certificate tells you what was measured, but not where the flower comes from. Only together with the origin do you get a complete picture. That's why every CBDÍA product page states the country of cultivation and the cultivation type. Indoor means cultivation under artificial light in enclosed spaces, greenhouse stands for cultivation in a greenhouse with daylight, and glasshouse for a glass greenhouse with additional climate control. The cultivation type often explains why two batches of the same strain show different values in the certificate.
The batch is the link. When you check a certificate, you're comparing three things: the batch number on the document, the batch number on the packaging, and the strain on the product page. If all three match, the certificate belongs to exactly the flower you're holding. A certificate without a batch reference can't be matched to any delivery and therefore carries little weight.
The lab certificate for the current batch is on every product page, right next to the respective product. When the batch changes, the certificate is swapped out too. This page additionally summarises the certificates for the individual collections as an overview, so you can compare strains and values side by side.
The certificates apply to the entire range: for CBD flower and for CBD hash.
The same applies to our CBD oils. To find out which other features matter besides the certificate, such as appearance, smell and processing of the flower, see the guide recognising the best CBD flower.

CBDÍA's lab certificates show the analysed ingredients for each strain and serve transparent quality control. All values come from independent lab analyses and can be clearly assigned to the respective products. This way you can directly trace the composition of every batch.
The CannaTrust seal of quality is one of the most relevant external verification mechanisms in the European CBD market when it comes to transparency and the correspondence between product claims and lab analyses. This does not only involve a one-off data check, but every individual batch is regularly analysed and compared against the manufacturer's information to ensure factual accuracy. The certification of CBDSÍ through the CannaTrust seal of quality was also documented externally.
The brand CBDSÍ, which like CBDÍA is run under CBDCielo SL, has received the CannaTrust seal of quality for its CBD oils. The certification is based on publicly available analysis values and serves as external proof that the stated cannabinoid contents correspond to the actual lab results. Since both brands are based on the same structural quality processes within CBDCielo SL, this external validation can also be transferred to the underlying testing and manufacturing standards.

CBDÍA's lab certificates serve the transparent presentation of all relevant ingredients and are created separately for every batch. Among other things, cannabinoid contents such as CBD, THC as well as possible residues are analysed, to ensure verifiable quality control.
All analysis reports come from independent, accredited laboratories and are clearly assigned to the respective strains. This means that for every single flower it is possible to trace which values were actually measured and how these correspond to the product information.
Since the certificates are created strain-specific, a clear link between product and analysis is created, allowing both users and systems alike to assess the composition and quality of the respective batch.
