II. Duties and Taxes

Product prices and shipping fees do not include any import duties, taxes, or customs clearance fees.

Customs duties and clearance policies vary by country/region. Unless the destination is covered by our tax-included shipping policy (e.g., most areas in the USA), buyers are responsible for paying any applicable fees to local customs or logistics companies upon delivery.

Some countries/regions may require additional customs documents or materials (e.g., commercial invoice, product list, etc.). If needed, APISQUEEN will actively assist and provide relevant documentation.

If goods are returned or destroyed due to the buyer’s failure to cooperate with customs, refusal to pay duties, or inability to provide necessary documents, all resulting shipping and related costs will be borne by the recipient.

Customs Declaration Notice

APISQUEEN will make reasonable and compliant declarations according to the requirements of the logistics company and the destination country/region.

The declared contents and quantities may vary depending on product type, shipping method, and local customs policies, and may not fully match the order payment amount.

The final duty amount is determined by local customs or the logistics company. APISQUEEN does not guarantee the amount of duties or the outcome of customs clearance.

Refunds will be processed after we receive the returned item and confirm it is intact.
