Shipping Policy

Last updated: July 31, 2026

This Shipping Policy applies to products purchased through the Shopify store operated by Middle Flat Lab Co., Ltd. (“we,” “us,” or “our”).

If a quotation, purchase order, individual agreement, or product page specifies shipping terms that differ from this policy, the individually stated terms will prevail.

1. Shipping Destinations

We generally ship products to addresses within Japan.

If you would like international shipping, please contact us before placing your order. We will provide information individually regarding availability, shipping charges, customs duties, import procedures, and other applicable conditions.

For certain remote islands, mountainous areas, and other locations, standard shipping methods may not be available or additional shipping charges may apply.

2. Shipping Charges

Shipping charges vary depending on the product, order quantity, delivery address, package size, and shipping method.

The shipping charge payable by the customer will be displayed on the checkout page before the order is completed, on the product page, or in a quotation or purchase order.

Charges different from standard shipping rates may apply in the following cases:

• Delivery to remote islands or certain regions

• Large-volume orders or heavy items

• Split shipments to multiple delivery addresses

• Requests for special packaging or shipping methods

• International shipping

• Reshipment required for reasons attributable to the customer

Where a product qualifies for free shipping, or an order meets the conditions for free shipping, this will be displayed on the product page or checkout page.

3. Shipping Time

In-stock products will generally be shipped within five business days after we confirm the order or payment.

For bank transfers and other prepaid orders, we begin preparing the shipment after confirming receipt of payment.

Our business days do not include Saturdays, Sundays, public holidays, year-end and New Year holidays, or other holidays separately designated by us.

For the following products, the estimated shipping date stated on the product page, quotation, purchase order, or in our communication with you will apply:

• Made-to-order products

• Custom-specification or personalized products

• Pre-order products

• Special-order products

• Large-volume orders

• Products awaiting restocking

If multiple products are ordered at the same time and some are awaiting restocking, we will generally ship the order after all products become available. If we or the customer wishes to arrange split shipments, we will discuss the details separately.

If we make a split shipment without the customer’s consent, we will not charge additional shipping fees exceeding the amount originally displayed.

4. Estimated Delivery Time

Products generally arrive within approximately one to three days after shipment.

However, delivery to Hokkaido, Okinawa, remote islands, certain mountainous areas, and other remote locations may take longer.

Shipment or delivery may be delayed due to the following circumstances:

• Weather, natural disasters, or traffic conditions

• High shipping volumes or other circumstances involving the carrier

• Delays in manufacturing, restocking, or customs clearance

• A need to confirm order details or delivery-address information

• Large-volume orders or orders requiring special packaging

• Other circumstances beyond our reasonable control

If a significant delay in shipment or delivery is expected, we will contact you where reasonably possible.

5. Carriers and Tracking Information

We select the carrier based on the product, delivery address, order quantity, and package size. Customers generally cannot choose the carrier.

If a shipping method with a tracking number is used, we will provide tracking information by email or another appropriate method after shipment.

Please note that it may take some time after the shipping notification for tracking information to appear in the carrier’s system.

6. Requested Delivery Date and Time

Where delivery date and time selection is available, this will be displayed during checkout or communicated individually.

A requested delivery date or time is conveyed to the carrier as a preference and does not guarantee delivery at the requested date or time.

Delivery date and time selection may not be available for large-volume orders, business deliveries, deliveries to remote islands, during peak carrier periods, or in other circumstances.

7. Confirmation of Delivery Address Information

Before completing an order, customers are responsible for confirming that the postal code, address, company or organization name, department name, contact person’s name, and telephone number for the delivery destination are correct.

If you notice an error in the delivery information, please contact us promptly. We may be unable to change the delivery address after the product has been shipped.

We are not responsible if a product cannot be delivered due to incorrect or incomplete delivery information, except where the issue is attributable to us.

8. Failed Delivery and Reshipment

If a product is returned to us for any of the following reasons, the customer may be responsible for the shipping charges and other actual costs required for reshipment:

• Extended absence

• Refusal to accept delivery

• Incorrect or incomplete delivery address

• Expiration of the carrier’s holding period

• Other circumstances attributable to the customer

If we contact you regarding a returned product and do not receive a response or payment of reshipment costs within a reasonable period, we may cancel the order. In that case, to the extent permitted by law, we may issue a refund after deducting shipping charges and other costs incurred by us.

9. Damage, Loss, or Incorrect Shipment During Delivery

Please check the product’s condition and order details promptly after delivery.

Contact us within seven days after receiving the product if any of the following applies:

• The product appears to have been damaged during delivery.

• You received a product different from the one ordered.

• The quantity received differs from the quantity ordered.

• The shipping status shows “delivered,” but you have not received the product.

• There is any other shipping-related issue.

If you suspect that a product was damaged during delivery, please do not dispose of the product, outer box, packaging materials, or shipping label. Please take photographs or videos that clearly show the condition.

After we and the carrier have confirmed the circumstances, we will provide an appropriate remedy, such as a replacement, reshipment, or refund.

If damage, loss, or an incorrect shipment is attributable to us or the carrier, we will bear the shipping costs required for a replacement or reshipment.

10. Transfer of Title and Risk

Title to the product transfers to the customer once payment of the product price and all other applicable charges has been completed.

The risk of loss of or damage to the product transfers when the product is delivered to the customer or the recipient designated by the customer, except where the issue is attributable to us or the carrier.

11. Returns and Exchanges

For returns, exchanges, refunds, and order cancellations, please refer to our Return and Refund Policy.

We generally do not accept returns or exchanges due to customer preference.
