How much does shipping cost?

We have two shipping methods - Standard Shipping and Express Shipping.

Standard Shipping is free for most countries/areas. When your order is over $45, then we can ship you with free standard shipping. 

Express Shipping via Yunexpress Expedited, FedEx, UPS, DHL, etc.  Expedited is 25 USD. 

Shipping fees exclude import taxes or processing fees applicable to your country. YUNZII is not responsible for any form of such fees. Should you refuse to pay the tax/customs fees, shipping fees will still be deducted from the amount paid for the returned parcel. For parcels that have been destroyed instead of being returned to us, no refund will be processed.

Standard Shipping via YunExpress is a tax-inclusive option for some countries. However, YUNZII will not be responsible for additional administrative or handling fees charged by your local courier company or customs.

For certain remote areas, there may be additional charges via Standard Shipping or Express Shipping. We will contact you if there is a need to.

Please contact us before placing an order, should you have any queries regarding shipping.

How long does it take to receive the order after it is placed?

For in-stock products, your order is expected to be shipped within 3 working days. Customized items take a longer time (do check in with our staff for more information). On normal non-sale days, once your parcel is shipped:

  • For Standard Shipping, it takes about 2-3 weeks for items to be delivered after it is shipped. For some countries, it might take up to 2-3 months, depending on your country and its custom procedure. The duration of transit is beyond our control. YUNZII does not arrange refunds for such cases. Please consider an upgrade to the Express Shipping method or keep the waiting time in mind.
  • For Express Shipping, it takes about 3-7 days for items to be delivered after it is shipped.


Shipping methods and periods might be affected and changed due to festive seasons, pandemic circumstances, or other unforeseen circumstances.

What happens if the parcel has been shipped but not delivered?

First, kindly contact your local courier using the local tracking number.

  • For orders below 45 USD, you may either opt for a one-time reshipment of the parcel OR a full refund.
For orders above 45 USD, we only process a 50% refund of your order.

Should there be any concern about Standard Shipping, you are encouraged to opt for Express Shipping instead.

Customers are to bear the consequences and fees incurred if the parcel is undelivered due to any of the following situations:

  • Wrong/insufficient address or phone number provided by the recipient
  • The recipient is unreachable when the courier company tries to contact
  • Refusal to sign for the package by the recipient
  • Lost or damaged parcel because recipient opted for “no-signature delivery”
  • Refusal to pay for the local tax/processing fee by the recipient
  • Refusal to provide supporting documents for customs clearance by the recipient

Who does pay for the import tax/customs fees?

Customers have to bear any form of custom/import/processing fees that are applicable to their parcel.

If the customs fees and the delivery of the parcel are rejected by the recipient, the shipping cost still needs to be paid. YUNZII only arranges the refund of the order amount after deducting the shipping cost incurred.
