International Delivery Service and VAT;
Custom Cable will use Royal Mail International Signed For worldwide for all items less than 2.0kgs. Items more than 2.0kgs are sent using Parcel Force Worldwide. For countries in the EU delivery times are estimated between 3-7 working days and slightly longer for all countries outside of the EU.
Customers in certain countries are also able to choose Royal Mail International Airsure. Airsure® is generally a day faster than standard Airmail and can be tracked online. Which means the aim is:
- 2 working days after posting to Western Europe
- 4 working days after posting to Eastern Europe and postal subsidiaries (Islands and Principalities)
- 6 working days after posting to the rest of the world
The above standards are monitored by the independent and impartial International Post Corporation to ensure reliable and consistent delivery, which is why Airsure® is only available to selected countries.
Please note that Airsure® is an upmarket mail, not a courier service. This means we cannot provide a guaranteed or certain delivery time, nor can we offer compensation for delays or missing Track & Trace information.
Prices for International Delivery are available at checkout and are specific for the delivery destination, please see here after adding your product to your cart.
VAT Free Countries
All EU member states will be subject to 20.0% VAT and countries outside of the EU will need to enter coupon code "VATFREE" at checkout to have the TAX deducted from the total amount ordered.
