Shipping policy
Shipping Policy
Last updated: August 7, 2026
Order Processing
Most Optimal Boxing products are sourced to order from Japan and are not held in our physical inventory.
Orders normally dispatch within 24–72 hours after payment confirmation. Dispatch occurs when the parcel is handed to the carrier. Tracking information is emailed after the carrier accepts the shipment.
Estimated Delivery
Tracked international shipping is estimated to take 8–10 business days after dispatch. Weekends and public holidays are not included in this estimate. This is a carrier transit estimate, not a guaranteed delivery date.
Shipping Charges
Shipping charges are calculated according to destination and shipment weight and are displayed during checkout.
Free shipping applies only when expressly displayed at checkout and when the qualifying order subtotal is met after discounts.
Customs, Duties and Taxes
Customs inspections, clearance holds, and processing times are controlled by destination authorities or carriers and are outside Optimal Boxing's operational control. They may extend delivery beyond the estimated 8–10-day transit window.
Unless checkout expressly states otherwise, the customer is responsible for import VAT, customs duties, brokerage charges, handling fees, and other destination-country charges. Nothing in this policy limits rights or remedies that applicable law does not permit Optimal Boxing to exclude.
Shipping Address
Customers must provide a complete and accurate delivery address.
Please contact us immediately if an address needs to be corrected. We cannot guarantee that an address can be changed after procurement or dispatch has begun.
Customers may be responsible for additional shipping costs caused by an incomplete or incorrect address, failed delivery, refusal of delivery, or failure to pay import charges, where permitted by law.
Delays and Supplier Availability
If an order cannot dispatch within the stated window, Optimal Boxing will contact the customer with a revised dispatch estimate and provide any delay, cancellation, or refund options required by applicable law.
Split Shipments
Orders containing multiple products may be consolidated into one shipment or sent separately. When products are shipped separately, more than one tracking number may be provided.
Lost, Damaged or Incorrect Shipments
Contact Support@mroptimal.io promptly if tracking shows a delivery problem or if an order arrives damaged or incorrect.
Please provide:
The order number
Photographs of the product and packaging
A photograph of the shipping label
A description of the problem
Keep all original packaging until the claim is resolved. We will provide the remedy required by applicable law.
Returns
Returns must be authorized before shipment. Do not return products to Winning, our Japanese supplier, or an address appearing on the outbound parcel unless specifically instructed in writing.
Return and exchange eligibility is governed by our Return and Refund Policy.
