Shipping Policy

Shipping Policy

This Shipping Policy describes how Kemvirox™ prepares, dispatches, and delivers orders placed through our online store. Please review the information below before completing your purchase.

1. Order Preparation

Orders require time for payment verification, item review, packing, and transfer to the shipping carrier.

Standard processing period:
2–4 business days

High-volume periods:
Processing may take up to 5 business days during holidays, promotional events, and other periods of increased order activity.

Business days do not include weekends or applicable public holidays. Processing time begins after an order has been successfully submitted and payment has been confirmed.

2. Shipping Charge

A flat shipping fee of $5.99 USD applies to each order.

The shipping charge is displayed during checkout before payment is completed.

3. Estimated Transit Times

Delivery estimates begin after the order has been processed and handed to the carrier.

Destination Estimated Transit Time
United States 10–15 business days
Canada, United Kingdom, and Australia 11–16 business days
Other International Destinations 15–20 business days

These timeframes are estimates rather than guaranteed arrival dates. Delivery may be affected by carrier operations, local postal networks, customs inspections, weather conditions, public holidays, or incomplete address information.

Processing time and shipping time are calculated separately.

4. Shipping Confirmation and Tracking

After your order has been dispatched, a confirmation email containing the available tracking information will be sent to the email address provided during checkout.

Please allow 1–3 business days for the carrier’s tracking system to display the first movement update. A temporary lack of tracking activity does not necessarily mean that the shipment has stopped moving.

Customers are responsible for monitoring the tracking page and checking for carrier notices concerning delivery attempts or collection instructions.

5. International Duties and Import Charges

International orders are shipped on a Delivered Duty Unpaid (DDU) basis unless otherwise stated during checkout.

This means that the recipient is responsible for any customs duties, import taxes, brokerage charges, or local fees applied by the destination country.

Kemvirox does not determine or collect these charges and cannot predict their amount. Customs requirements vary by location. Contact your local customs authority if you need information about possible fees before ordering.

Customs inspections may extend the delivery period. Kemvirox is not responsible for delays created by customs processing or local import procedures.

6. Address Changes and Cancellation Requests

If you need to correct a shipping address or request an order cancellation, email us within 12 hours after placing the order:

service@kemvirox.com

Include your order number and the requested change in your message.

Requests received within this period will be reviewed, but changes cannot be completed after an order has entered processing, packing, or shipment. Confirm that the delivery address is complete and accurate before submitting payment.

7. Incorrect or Incomplete Addresses

Customers are responsible for providing a complete shipping address, including the recipient’s name, apartment or unit number, street information, city, state or region, postal code, and country.

Additional shipping charges may apply if a package is returned because the address was incomplete, incorrect, or could not be verified by the carrier.

8. Packages Arriving with Visible Damage

If an order arrives with visible shipping damage, contact us within 72 hours of delivery at:

service@kemvirox.com

Please include:

  • Your order number

  • A description of the issue

  • Photographs of the outer package

  • Photographs of the affected item

  • A photograph of the shipping label

After reviewing the submitted information, we will arrange a replacement for an eligible damaged item at no additional charge.

Keep the original item and packaging until our customer care team has completed its review.

9. Shipments Confirmed as Lost

A shipment is considered lost only after the shipping carrier has completed an investigation and formally confirmed that the package cannot be located.

When a carrier confirms a shipment as lost in transit, contact us with your order number and the carrier’s confirmation. After verification, we will arrange a replacement at no additional charge.

10. Packages Marked as Delivered

If tracking shows that a package was delivered but you cannot locate it:

  1. Review the delivery location shown in the tracking information.

  2. Check entrances, mailrooms, reception areas, parcel lockers, and other locations around the property.

  3. Ask household members, building staff, or nearby neighbors whether they accepted the package.

  4. Contact the carrier for delivery details.

If the package remains missing after these steps, email service@kemvirox.com with your order number and any information supplied by the carrier.
