Nearly all European postal services (Scandinavia, Austria, UK etc.), including our Czech postal service have paused accepting US-bound shipments because it is unclear how they should collect the new import duty on behalf of the US, neither do they yet have the IT solution in place to do so (link to their letter to all major exporters to the United States which they also sent to our CEO):
Based on the new executive order of the US President, the “de minimis” duty-free regime for all postal shipments with a value of zero to 800 USD imported into the USA is being canceled with effect from August 29, 2025. Fundamental issues and procedures, especially in the area of customs duty collection, specification of data collected and method of cooperation with US customs authorities, have not yet been clearly defined by the relevant US authorities. Partial technical details were published only on August 15, which left an extremely limited time for preparing the technical transfer of data to the US side, as well as for setting up the customs duty collection, which must be done when the sender submits the shipment. For this reason, it is not possible to ensure compliance with the requirements of the executive order at this time. For Czech Post customers, this means that from August 22, 2025 until further notice, the reception of shipments to the USA that contain merchandise will be suspended, regardless of their value.
The cause of the problem is the highly unusual demand by the US that the sender pays the new US import tax ('tariff') on behalf of the receiver. No European national postal service has the logistical IT infrastructure for that yet. Couriers such as FedEx do have that option but charge an unfeasible cost of shipping and also, we have no IT infrastructure to support them yet. We normally send 50 packages/day to the US via the Postal service's digital communications, payment and labels. This issue is an emergency for all European exporters to the US and extremely inconvenient for many Americans so we expect this situation to be resolved soon. We will update you about the situation here.

20 grams of Chloramine-T to make 1 to 4 litres (more than 1 gallon) of disinfecting solution for dermarollers, dermastamps and needles.
Chloramine-T sterilizes, whereas alcohol only disinfects. Alcohols may damage the plastic and glue (to secure the needles with) used in the dermaroller head but Chloramine-T is safe. Read the scientific publication where it says that Chloramine-T sterilizes. Chloramine-T is bactericidal and has antibiotic properties. That is why it is much more effective than alcohol or chlorine.
Milton fluid destroys dermaneedling instruments because it contains free Chlorine. Alcohol with a sufficient Ethanol percentage may be hard to find. Chloramine-T is the cheapest, safest, most effective sterilizing solution.
The cleaning and sterilizing procedure is on page 7 of our general dermaneedling guidelines.
A 0.5% solution can also be used to treat acne overnight with (wet the area and put a plaster over it). Do not use Chloramine-T for general skin disinfection.
When you put the roller in it overnight, a 0.5% solution will do, making Chloramine-T by far the cheapest sterilizing solution for your dermarollers. In addition, Chloramine-T sterilizes faster than alcohol and is active against more pathogens. It is highly effective against all bacteria, viruses, parasites and spores. Chloramine-T is not the same as ordinary Chloramine, because:
Chloramine-T is not primarily a chlorine disinfectant. It only releases max 2.5% chlorine during the active phase in contrast to 100% with chlorine disinfectants.
Although Chloramine-T is a chlorine compound, it attacks the peptide bonding of the proteins when the complete active substance molecule comes into contact with micro-organisms (virus, bacteria, fungus or yeast), in addition to having the effect of conventional chloride disinfectants, which continually split off chlorine.
Chloramine-T is commonly used for wound disinfection, but mainly for the disinfection of materials and surfaces in hospitals.
Use a 2% solution for quick disinfection, and a 1% or 0.5% solution when you leave the dermaroller, dermastamp or single needle in it overnight (8 hours exposure).
A 2% solution is made with 20 grams in 1 litre of water.
A 1% solution is made with 20 grams in 2 litres of water. (or 10 grams in 1 litre, etc.)
A 0.5% solution is made with 20 grams in 4 litres/1 gallon of water. (or 10 grams in 2 litres/half a gallon etc.)
If you want to make 20 times less than a gallon, use 1 gram, etc.
A Chloramine-T solution should be kept in the fridge, where it will keep its potency for one month. Make it a little stronger if you want to keep it longer.
Do not use on the Original Derminator needle cartridges! (It CAN be used on the Derminator 2's cartridges.)
