Shipping & Delivery

1. Order Processing

Orders placed directly through kastu-bath.com are processed after successful payment completion and verification.

Most direct website orders are normally prepared within 1–3 business days, excluding weekends, public holidays, peak shopping periods and unusual circumstances.

Processing time means the period required to confirm, prepare and pack the order before carrier handoff. It is separate from delivery transit time.

2. Shipping Methods

Available shipping methods may depend on destination, product availability, warehouse or fulfilment location, order value and carrier availability.

Available methods and charges are shown through checkout where applicable.

3. Estimated Delivery Times

Delivery estimates depend on carrier, destination and service level. Unless specifically stated otherwise, estimated arrival dates are estimates rather than guarantees.

4. Tracking Information

Where carrier tracking is available, customers may receive tracking information after the parcel is shipped.

Tracking systems may require additional time after carrier acceptance before movement becomes visible.

5. Shipping Address Accuracy

Please verify all address information before ordering, including:

• Recipient name.
• Street address.
• Apartment, suite or unit number.
• City.
• State, province or region.
• Postal or ZIP code.
• Country.
• Contact email or telephone number where required.

Incomplete or incorrect information can cause delays, failed delivery or return-to-sender events.

6. Changing an Address

If you notice an address error after ordering, contact us immediately. We will try to assist before the parcel has been packed or shipped.

Address changes cannot be guaranteed after fulfilment processing begins.

7. Shipping Charges

Shipping charges, where applicable, may depend on destination, service level, order weight, carrier and promotional terms.

The amount payable is displayed during checkout before payment confirmation.

8. International Shipping

International delivery availability depends on destination, product and fulfilment method.

International parcels may be subject to customs review, import taxes, VAT, duties or brokerage charges.

9. Customs & Import Charges

Unless checkout specifically states that duties are included, destination-country customs charges, import taxes or duties may be payable by the recipient.

Customs processing is controlled by government authorities and can create delays outside our control.

10. Weather, Carrier & External Delays

Severe weather, public holidays, customs, carrier capacity, transportation disruption and other circumstances outside our reasonable control may delay delivery.

11. Tracking Says Delivered, but the Parcel Is Missing

If tracking shows “delivered,” check:

• Mailbox or parcel locker.
• Front and side entrances.
• Reception or building management.
• Safe delivery areas.
• Neighbours where appropriate.

You may also contact the carrier for location details.

12. Potentially Lost Parcels

If tracking has stopped updating for an unusually long period, contact the carrier and then contact KASTU with the order and tracking information.

13. Damaged During Shipping

14. Multiple Shipments

An order may occasionally arrive in multiple parcels. Different parcels may have different tracking numbers and delivery dates.

15. Returned-to-Sender Parcels

A package may be returned because of an incorrect address, failed delivery attempts, refusal, unpaid import charges or failure to collect the parcel.

Additional shipping charges may apply to reshipment where permitted.

16. Marketplace Orders

Orders placed through Amazon or another third-party marketplace generally follow that marketplace's shipping, tracking and delivery-support procedures.

17. Shipping Support

For a direct KASTU order, email langruizhubao@foxmail.com and include your order number and tracking number if available.
