Shipping policy
This Shipping Policy applies to orders placed through o3-performance.com.
1. Where We Ship
O3 ships from Switzerland to destinations made available at checkout, including Switzerland, European destinations, the United Kingdom, the United States and other supported countries.
Available destinations may change because of carrier availability, customs requirements, sanctions, legal restrictions or other circumstances outside O3’s reasonable control.
If we cannot lawfully or reasonably fulfil an order to the selected destination, we will contact you and refund any amount paid where the order cannot proceed.
2. Shipping Charges
Available shipping methods and charges are shown at checkout before payment.
Shipping rates may vary depending on destination, order value and available service.
Where free shipping is offered above a specified order value, the applicable threshold will be displayed on the website or at checkout.
3. Processing, Dispatch and Estimated Delivery Times
Please allow up to 5 business days for order processing before dispatch.
O3 orders are dispatched from Switzerland using Swiss Post. Processing time is separate from carrier transit time, which begins once your order has been dispatched.
Estimated transit times after dispatch are:
- Switzerland: approximately 2 working days
- Europe: approximately 2–7 working days, depending on destination
- United Kingdom: approximately 2–4 working days
- United States: approximately 3–7 working days
- Other international destinations: delivery times vary by destination and Swiss Post service
These are estimated transit times and are not guaranteed delivery dates. Customs processing, public holidays, local postal networks and other circumstances may cause additional delays.
Where a more specific delivery estimate is available, it may also be shown at checkout, in your dispatch confirmation or through Swiss Post tracking.
O3 will comply with any mandatory delivery periods and consumer rights applicable to your order.
4. Order Confirmation
After placing an order, you will receive confirmation at the email address provided during checkout.
Please check your order carefully. If anything is incorrect, contact:
as soon as possible and include your order number.
5. Tracking
Where tracking is included with the selected Swiss Post service, tracking information will normally be provided after dispatch.
Tracking may take some time to become active after the parcel has been handed to Swiss Post or a destination postal partner.
6. Customs, VAT, Duties and Other Charges
International orders may be subject to import VAT, customs duties, customs-processing charges, carrier handling fees or other charges imposed in the destination country.
Where applicable taxes or charges are collected by O3 or through checkout, they will be included in the amount shown before payment.
Where they are not collected at checkout, the recipient may be responsible for charges imposed by customs authorities, postal operators or other authorities, subject to applicable law.
United Kingdom
O3 has applied for UK VAT registration.
Where UK VAT is required to be accounted for by O3 from its effective registration date, O3 will account for that VAT in accordance with UK VAT rules.
While O3’s VAT registration number is pending, VAT will not be separately stated as VAT on invoices or order documentation.
For goods sent directly from Switzerland to UK customers in a consignment valued at £135 or less, UK VAT rules generally require VAT to be accounted for at the point of sale.
The £135 threshold applies to the consignment as a whole, rather than each individual product.
For consignments valued above £135, normal UK import VAT and customs rules apply. Import VAT, customs duties or carrier clearance charges may therefore be payable on import where they have not already been collected at checkout.
7. Customs Information
Customers must provide accurate information reasonably required for delivery and customs clearance.
O3 may provide Swiss Post, destination carriers and customs authorities with information needed to process a shipment, including product descriptions, values, country of origin and customs classifications.
8. Delivery Address
Customers are responsible for providing a complete and accurate delivery address.
If you notice an error after ordering, contact:
as soon as possible.
We will try to make changes before dispatch but cannot guarantee that an address can be changed once fulfilment or shipping has begun.
9. Order Changes and Cancellations
To request an amendment or cancellation before fulfilment, contact:
You may also submit a cancellation request through your O3 customer account where available.
We cannot guarantee cancellation once fulfilment or dispatch has begun.
Nothing in this section affects mandatory statutory cancellation or withdrawal rights.
10. Failed, Refused or Unclaimed Deliveries
If a parcel cannot be delivered because of an incorrect or incomplete address, refusal of delivery or failure to collect the parcel, we will contact you regarding the available options.
Where permitted by law, reasonable additional return or reshipping costs may be charged.
Refusing or failing to collect a parcel does not by itself constitute a valid statutory withdrawal or cancellation.
11. Lost Shipments
If you believe your order has been lost in transit, contact:
Please include your order number and any relevant tracking information.
We will investigate with Swiss Post or the relevant destination carrier and provide any remedy required by applicable law.
12. Damaged Shipments
If your parcel or product arrives damaged, contact:
Please include your order number, a description of the issue and photographs where reasonably possible.
We will assess the issue in accordance with our Return & Refund Policy and applicable law.
13. Delivery Delays
Delivery may occasionally be delayed by customs processing, weather, carrier disruption, strikes, public holidays, border disruption or other circumstances outside O3’s reasonable control.
Where a material delay occurs, we will take reasonable steps to assist and comply with any mandatory cancellation, refund or delivery rights applicable to your order.
14. Risk During Delivery
Nothing in this policy changes mandatory legal rules governing when risk passes to the customer.
Where applicable consumer law requires O3 to remain responsible until the goods are physically received by the customer or a person nominated by them, those rights remain unaffected.
15. Returns
Returns, exchanges, withdrawals and refunds are governed by our Return & Refund Policy.
