Delivery options and timing

The options available to you, their charges and their estimated timeframes are shown at checkout once you have entered the delivery address. Processing time and carrier transit vary with when the order is placed, product availability, the destination, the carrier’s own operation and conditions outside our control, so no universal 24-hour or 48-hour promise is made and none should be relied on. Timeframes are estimates, not a guarantee of delivery on a particular day.

Carriers and tracking

We dispatch with established carriers such as Royal Mail and DPD. Where tracking is provided for your order, the tracking details are in the dispatch email; use the carrier’s own tracking page for the latest status.

Packaging

Materials travel in their supplied presentation, whether sealed vial, refill cartridge or pre-filled pen, with the research-use-only marking on the container label. Outer packaging is plain and does not describe the contents. Packaging is chosen for the material and its declared storage conditions; an insulated parcel is not automatically a cold-chain shipment, and no stability period should be inferred from the packaging alone. Our cold-chain and temperature-stable shipping guide explains the difference.

Documentation with the order

Where a certificate of analysis exists for the lot supplied it is issued with the consignment. How batch documentation works.

On receipt

Check that the lot identifier on each container matches the lot on the accompanying certificate, and that the presentation and quantity match what was ordered. Do this before the material is used: a discrepancy reported after use cannot be investigated properly. The receiving inspection checklist sets out a structured check.

Delays, damage and temperature concerns

If a delivery is delayed, arrives with visible damage, or gives you a temperature concern, keep the order reference, the lot identifier where you have it, the tracking information and clear photographs, then email info@core-research.net. Damage must be reported within 24 hours of delivery with photographs taken before opening; the returns policy sets out when we replace lost, damaged or wrongly packed orders, and our guide covers what to do if a product arrives warm or delayed.

International orders

Where an order is sent outside the United Kingdom, import duties, taxes and customs formalities in the destination country are the recipient’s responsibility. Delays, seizures or rejections at customs are outside our control and are not grounds for a refund or replacement.

Research-use boundary

Everything dispatched is supplied for laboratory research use only. Not for human or veterinary use, and not for use in food or as a drug.
