by Wega- Tea import
Tea is an agricultural product, and therefore may come into contact with pesticides during cultivation. Their use does not automatically mean that the tea is unsafe or cannot be sold in the European Union. The key is that, what substances were detected and in what concentration and whether their residue levels meet the requirements applicable on the EU market. For a tea importer, this means verifying not only the sensory quality of the product, but also its compliance with European food safety requirements.
What are MRLs?
The primary legislation regulating pesticide residue levels in food is Regulation (EC) No. 396/2005 of the European Parliament and of the Council. It establishes maximum permissible levels for pesticide residues, known as MRLs (Maximum Residue Levels). MRLs are not a single, universal value for all pesticides and all products. The permissible level depends on the specific active substance and the specific product category. Therefore, tea test results should always be compared to the limit applicable to the substance in tea. Current values can be checked in the EU Pesticides Database, maintained by the European Commission, which allows searching for MRLs by product and substance. However, the Commission emphasizes that the database is for informational purposes only, and that regulations published in the Official Journal of the European Union have legal force.
The standard of the country of manufacture is not sufficient
In the case of teas imported from outside the European Union, one rule is particularly important: a product's compliance with the requirements in force in the country of origin does not automatically mean compliance with EU requirements. Tea can meet the requirements in force in the producer's country and yet contain residue levels that do not meet the European MRL. EU regulations on the control of imported food are based on the principle that products from third countries introduced to the EU market must meet the relevant requirements of EU law or requirements recognized as at least equivalent. Therefore, when importing tea, the manufacturer's information that the product "meets standards" or that the test result is "OK" is not sufficient. It is important to know the standards according to which the assessment was performed.
A Certificate of Analysis is just the beginning
The manufacturer can provide the importer with a certificate of analysis or a laboratory report. Such a document is an important element of quality control, but it should be thoroughly verified. The scope of the test is crucial. Laboratories may use different analytical panels covering different numbers of substances. The statement itself „compliant”, "pass," or "pesticide residues: OK" does not yet indicate which compounds were actually tested. When evaluating a report, it is worth checking, among other things, the sample and production batch designation, the test date, the method used, the list of tested substances, the results obtained, and the limits of detection. Equally important, results for one batch of tea should not automatically be considered as confirmation of compliance for subsequent batches. Tea is an agricultural product, and growing conditions and plant protection products used may vary.
MRL and limit of quantification
Laboratory reports often use the acronym LOQ – Limit of Quantification, meaning the limit of quantitative quantification of the method used. MRL and LOQ mean two different things. MRL defines the legally established maximum permissible residue level of a given substance in a given product. LOQ, on the other hand, refers to the analytical method's capability – the level from which the laboratory can reliably determine the quantity of a given substance. Therefore, correct interpretation of a report requires considering not only the result itself but also the test method and its parameters.
What does exceeding the MRL mean?
A laboratory result above the MRL requires proper interpretation. Measurement uncertainty is also taken into account in pesticide residue analyses. Current EU guidelines for analytical quality indicate a default expanded measurement uncertainty of 50%, corresponding to a confidence level of 95%, provided the laboratory meets certain requirements. When assessing compliance for MRL enforcement purposes, a sample is considered non-compliant if the result, after subtracting the expanded uncertainty, still exceeds the MRL, i.e., when x – U > MRL. However, this does not mean that one can simply "add 50%" to the MRL and obtain a new acceptable standard. The MRL remains unchanged. Measurement uncertainty is a factor in the interpretation of the analytical result and in deciding whether a sample complies, not an increase in the legal limit. This is an important difference, as a result slightly above the MRL requires a different interpretation than a result many times above the applicable limit.
The importance of proper sampling
Even the most precise laboratory test is of limited value if the sample tested does not represent the actual batch. Since 2026, the rules for sampling, analysis methods, and interpretation of results for official pesticide residue controls have been defined in Commission Implementing Regulation (EU) 2026/765, which replaced the previous Directive 2002/63/EC. The goal of proper sampling is to obtain material representative of the batch being tested. This is particularly important for large commercial shipments, as a small amount of tea accidentally sampled may not always represent the entire product. Therefore, the ability to link the test result to a specific production batch and delivery is also crucial.
Who is responsible for imported tea?
Responsibility doesn't end with a producer located thousands of kilometers from Europe. EU general food law imposes obligations on food businesses. The system is based on the premise that operators are primarily responsible for ensuring their compliance with food law, while official inspections serve to verify this compliance. In practice, this means that an importer introducing tea from a third country into the EU market cannot transfer all responsibility to a foreign producer or its laboratory. Therefore, it is crucial to have their own inspection procedures, delivery documentation, batch identification, and an appropriate response if a problem is identified.
Batch traceability matters
Regulation (EC) No. 178/2002 requires food traceability. Businesses should be able to identify who received the product and to whom they subsequently delivered it, and appropriate systems and procedures should enable this information to be communicated to the relevant authorities. In the case of imported tea, this effectively means information such as the manufacturer, batch number, delivery documentation, test results, and recipients of the batch. If a product safety issue arises, traceability allows for the identification of the specific tea concerned and its destination.
What if the problem is detected after the tea has been released to the market?
If an operator has reason to believe that food they are importing or distributing does not meet safety requirements, Article 19 of Regulation (EC) No. 178/2002 requires them to immediately initiate a product withdrawal procedure once the product has left their direct control and to notify the competent authorities. If the product may have reached consumers, the regulations also provide for appropriate consumer information and, if necessary, the recall of products already supplied. Therefore, pre-sale pesticide residue testing is not only a part of quality control. It also helps reduce the risk of a much more serious situation after the product is placed on the market.
Inspection should begin before shipment
In tea imports, it's particularly beneficial to detect problems as early as possible – before several tons of product enter a container bound for Europe. Therefore, the inspection process may include the manufacturer's documentation, testing a sample representing a specific batch, checking the scope of the analysis, and comparing the results with the current MRLs in force in the EU. Depending on the risk assessment, the importer may also commission its own laboratory tests. This is not due to a lack of trust in the manufacturer. In international food trade, the principle „trust, but verify” protects both sides of the transaction.
Safety and quality are two different issues
A tea can have excellent leaf appearance, intense aroma, and excellent flavor, yet still fail to meet pesticide residue requirements. The reverse is also possible: a tea can meet safety requirements but not meet accepted quality standards.
Therefore, when importing, two questions should be separated:
- Does tea meet food safety requirements?
and
- Is the tea of the quality that the importer and his customer want to buy?
Sensory evaluation does not replace laboratory testing, and a correct laboratory result does not replace an assessment of tea quality.
Responsible importing starts before the container arrives
Pesticide residue control is one of the most important elements of risk management when importing tea. It's not just about obtaining a single certificate from the producer. What matters are the current EU requirements, the appropriate MRL for a given substance, the scope of the laboratory analysis, the representativeness of the sample, the ability to assign the result to a specific batch, and the correct interpretation of the data obtained. Only the combination of these elements allows the importer to make an informed assessment of the product before it is released for sale.
Important: MRL regulations and detailed control requirements are updated. Before making a decision regarding a specific batch of tea, always check the current regulations and applicable values for a given substance. The EU Pesticides Database is a convenient search tool, but the Commission itself indicates that the database is for informational purposes only; the legal source remains acts published in the Official Journal of the EU.
