11. SHIPPING DELAYS

Shipping timelines are estimates, not guarantees.

Orders placed between 7 Feb – 24 Feb annually may experience 1–2 week shipment delays due to logistics provider notice.

Additionally, shipments may be subject to inspection by U.S. Customs, shipment originating customs or the destination country’s customs authority. While we work closely with our logistics partners to ensure prompt clearance, customs inspections are conducted in accordance with government regulations and may result in extended processing times beyond our control.

Customs inspections are random and outside of MK Aquarium Store’s control. If a shipment is selected for inspection by U.S. Customs or the destination country’s customs authority, clearance may take up to 30 days, or longer if required by the customs authority, until the inspection is fully completed.

During this period, MK Aquarium Store and its logistics partners cannot force release of the shipment. We will continue monitoring the shipment and providing updates where available, but customs inspection delays do not qualify for cancellation, refund, or compensation.

In such cases:

  • Delays may occur due to mandatory government inspection procedures
  • Release timelines are determined solely by the relevant customs authority
  • These delays do not qualify for refunds or cancellations

Customers may contact us at any time for shipment updates. We monitor freight routinely and will provide status updates as they become available.
