    My order hasn't arrived yet. Where is it?

    Once your order has been shipped, we will email you the tracking number so you can check the status via the corresponding carrier's website. If you have any questions, please contact us at info@extrelab.com.

    Do you deliver on public holidays?

    Do you deliver to my postcode?

    Yes,We will submit the detailed address provided by the customer to UPS or USPS for delivery. If the provided address is incomplete or incorrect, we will contact the customer to confirm the correct address before shipping.

    Is next-day delivery available on all orders?

    Delivery typically takes 5–7 days; if it exceeds 14 days, please contact us immediately, info@extrelab.com. Delivery time depends on the distance between your address and our warehouses—we ship from California or New Jersey, so delivery may be faster if you are closer to either of these locations.Please note that we only provide shipping services within the contiguous United States; this excludes Hawaii, Alaska, and Puerto Rico. If you are shipping to any of these locations, please contact us before placing your order.

    Do I need to be there to sign for delivery?

    We encourage customers to sign for the delivery in person to prevent loss or damage. However, should the goods arrive damaged—even if not signed for in person—we will still send a replacement, provided the customer supplies a video or photograph as proof.
