The UK is not the EU: what that means for a peptide shipment
English-language searches for peptides are full of the letters uk. That matters more than it looks, because the United Kingdom left the European Union, and for a temperature-sensitive shipment that changes the physical product that arrives.
Europe and the European Union are not the same
| Destination | In the EU | What happens |
|---|---|---|
| Ireland, Netherlands, Germany, France, Spain, Italy, Poland, Sweden | Yes | No customs, no import duty, cold chain across the whole route |
| United Kingdom | No | Customs clearance since Brexit |
| Switzerland, Norway | No | Customs clearance |
Why a customs hold matters for peptide specifically
Lyophilised peptide is freeze-dried powder. Sealed, it is reasonably stable, and that is exactly why it ships in that form. But reasonably stable is not indestructible.
Two things degrade it. Heat accelerates breakdown of the peptide chain. And moisture entering through the rubber stopper partially dissolves the powder, after which degradation runs considerably faster. That is why a serious supplier measures water content by Karl Fischer titration.
The problem with a customs hold is not the duration itself. It is that a window exists in which nobody knows where the parcel sat or at what temperature. A customs depot is not a cold room.
What a certificate does and does not cover
A certificate of analysis describes the batch at the moment it was tested, usually at production. It is valuable and we supply it on request per batch number. It says nothing about what three weeks of warmth did afterwards. Anyone serious reads the certificate and the route.

Frequently asked questions
Do you ship to the United Kingdom?
The UK left the EU, so a shipment there goes through customs clearance with a delay we cannot control.
Do I pay import duty inside the EU?
No. The shipment stays within the EU, so there is no customs handling and no import duty.
Is Switzerland in the EU?
No. Neither is Norway. Customs clearance applies to both.
Does a certificate say anything about condition after transport?
No. It is a snapshot of the batch, usually at production.
Is the packaging discreet?
Yes. The outer packaging carries no reference to the contents.
Ordering and paying within the EU
We ship from within the EU with cold chain, so no customs clearance and no import duty. That is not a formality: lyophilised peptide tolerates heat poorly, and a customs depot is not a cold room. The full catalogue with the price per milligram is on Buy peptides in Europe.
Quality criteria for research grade
The difference between suppliers lies in what they can demonstrate, not what they claim. A certificate tied to your batch number rather than a product page. Two independent methods: HPLC for purity, mass spectrometry for identity. Karl Fischer titration for water content, which determines how long the powder stays stable. And a cold chain that matches the distance.
Paying at Chempeptides
You complete your order first, then reach a secure payment page with the exact amount and your order number. There you choose Wero, credit card, Apple Pay or Google Pay. Which methods appear depends on the country you pay from. No card number is entered on our site.
In closing
Purity is measured at departure, quality is delivered on arrival. The route sits between those two, and it appears on no certificate.
