The EU lowered the limits for two neonicotinoid insecticides in tea to the level of analytical determination. A three-year transition period ended on 7 March 2026 — so any tea crossing EU customs now has to meet the new numbers.
Commission Regulation (EU) 2023/334 was published in the Official Journal on 15 February 2023. It entered into force on 7 March 2023, but applied only from 7 March 2026 — a three-year transition period intended to give growers outside the EU time to change their field practice.
The regulation amends Annexes II and V to Regulation (EC) No 396/2005 for two substances: clothianidin and thiamethoxam. For tea, both are now 0.05 mg/kg.
| Compound | Previous limit for tea | Limit from 7 March 2026 |
|---|---|---|
| Clothianidin | 0.7 mg/kg | 0.05 mg/kg |
| Thiamethoxam | 20 mg/kg | 0.05 mg/kg |
0.05 mg/kg is the limit of analytical determination — the lowest level laboratories can reliably measure for these compounds in a tea matrix. In practice the EU has moved both substances to the lowest number it can set, which is why the change is often described as a de facto ban on their use in tea grown for the EU market.
Note that a residue at or above the limit is not a quality issue that can be blended away. It fails the consignment.
Both substances are neonicotinoids. EFSA concluded in 2018 that outdoor use of thiamethoxam poses a significant risk to bees, and approvals were not renewed. In January 2023 the Court of Justice of the European Union ruled that emergency authorisations for thiamethoxam were no longer permitted.
The regulation's stated aim is that imported products should be free from clothianidin and thiamethoxam. WTO members have criticised the measure — Australia called it a de facto ban on the use of those products by trading partners — but the limits stand.
The two neonicotinoids above are the headline. The bigger practical risk is the default rule: for any pesticide not specifically listed in the regulation, the EU applies 0.01 mg/kg. That means a compound legally used in China, but never registered in the EU, can still fail an EU consignment at the lowest measurable level.
This is the single most common reason Chinese-origin tea is stopped at EU border control, and it is why a residue report drawn against Chinese standards is not enough for an EU buyer.
| Substance | Status in the EU |
|---|---|
| Clothianidin | Not approved; tea limit 0.05 mg/kg since March 2026 |
| Thiamethoxam | Not approved; tea limit 0.05 mg/kg since March 2026 |
| Imidacloprid | Restricted to indoor greenhouse use |
| Thiacloprid | Approval not renewed in 2020 |
| Acetamiprid | The only neonicotinoid authorised without restriction |
If your supplier still speaks of neonicotinoids as one category, that is a signal they have not re-examined their own panel against the 2026 numbers.
Our EU-standard grade is produced to EU residue limits, with batch residue testing arranged to your destination market's requirements. Test documentation travels with the sample, the quotation and the shipment, and the batch numbers match across all three.
Our organic grade holds China Organic and USDA NOP certification. Neither is recognised as EU organic, and we never present them as such to EU buyers.
If you need the current batch report before quoting, ask and we will send it — with the batch number visible.

Clothianidin and thiamethoxam, both not approved in the EU, with tea limits of 0.05 mg/kg since March 2026. Acetamiprid is the only neonicotinoid still authorised without restriction.
Because it catches anything not specifically listed. A pesticide legally used in China but never registered in the EU can stop a consignment at the lowest measurable level, even though the tea passed Chinese standards.
Ask in writing which laboratory issued the residue report and whether it is accredited, whether the panel names clothianidin and thiamethoxam individually with a result for each, and whether the batch number matches the packing list and invoice.
Send us your target market and grade and we will confirm exactly what the current batch can document.
