+

+
+> Applies to in-stock orders shipped from our Netherlands warehouse. For items shipped from our factories, see [07-factory-direct](07-factory-direct.md).
+
+### Q: What shipping options do you offer?
+For all deliveries we offer two carriers: **PostNL** or **DHL**. The actual shipping rate is shown in your cart during checkout. If your order reaches the **free-shipping threshold** and you select DHL, the PostNL fee is deducted from the DHL fee and you only pay the surcharge.
+
+### Q: What shipping costs do you charge?
+Yehwang ships worldwide from the Netherlands via PostNL and DHL. **Shipping cost depends on your destination country and the weight of your package** — each country has its own rates based on distance and local shipping expenses. The exact cost is shown when you select your country during checkout.

+
+### Q: When will my order arrive / how fast do you dispatch?
+Orders received **before 3 PM on business days are shipped within 1–3 business days**. We don't ship on weekends; orders placed Friday after 3 PM ship the following Monday. During clearance periods dispatch may take a little longer. After shipment you receive an email with a **Track and Trace** link. Transit times vary by country — check the carrier's site (via the tracking link) for an up-to-date ETA.
+
+### Q: Will I receive a track and trace code?
+Yes — you'll receive a track and trace code by email from PostNL. If you haven't received it, contact **helpdesk@yehwang.com** and include your order number.
+
+### Q: How does Brexit affect shipping to the UK?
+We still ship to the UK; Brexit does not stop this. However, on orders over **GBP 135** (excl. VAT and shipping), UK customs may charge import duties and taxes. These costs are paid by the customer — Yehwang does not cover them.
+
+### Q: My package hasn't been delivered. What now?
+Contact us at **helpdesk@yehwang.com** with your order number. We'll open an investigation with the carrier (this can take **1–3 business days**). If the carrier declares the package lost, we refund the purchase amount once there is evidence/confirmation from the carrier that it was not delivered.
