Shipping policy.

Orders are reviewed and packed on business days (Monday to Friday, excluding Dutch public holidays). Orders placed before 15:00 CET are normally dispatched the same business day; orders placed after that time, at weekends or on holidays are dispatched on the next business day.

Payment must be fully settled and, for bank transfers, received in our account before an order is released for dispatch. Bank transfers are matched using the sequential payment reference shown on your order confirmation.

We ship from the Netherlands to addresses within the European Union and the wider EEA. We do not ship outside the EU/EEA.

It is the buyer's responsibility to confirm that the import, possession and laboratory use of the ordered reference materials is lawful in their country before ordering.

Standard tracked EU shipping is charged at checkout at a flat rate. Orders above the free-shipping threshold displayed in your cart ship free of charge. All prices and shipping charges are shown in euro (EUR) and include applicable Dutch VAT where required.

Typical tracked transit times after dispatch:

• Netherlands, Belgium, Germany: 1–2 business days
• Rest of the European Union: 2–5 business days
• Remote or island regions: up to 7 business days

Delivery times are estimates, not guarantees. Carrier delays, customs inspections, incorrect addresses and force majeure fall outside our control.

Lyophilised peptides are stable at ambient temperature for the duration of normal transit and are shipped in discreet, unbranded protective packaging with the certificate-of-analysis batch reference on the inner label. On arrival, store material as stated on the product page — typically refrigerated at 2–8 °C, or frozen for long-term storage.

A tracking number is emailed as soon as the parcel is handed to the carrier. If tracking has not updated for five business days, contact support@reta24.nl with your order reference and we will open a carrier investigation.

Report a damaged parcel within 48 hours of delivery with photographs of the outer packaging and the contents. Parcels not delivered within 15 business days of dispatch are treated as lost and are replaced or refunded once the carrier investigation closes.

Failed deliveries caused by an incorrect or incomplete address supplied by the buyer, or by refusal to accept the parcel, are re-shipped at the buyer's expense.

Shipments inside the EU customs union do not normally attract import duties. Where a destination applies local charges, those charges are payable by the buyer.
