Shipping policy

Effective date: October 10, 2026

Where we ship

We ship to destinations supported by our checkout. Enter your address at checkout to see available shipping options. If no shipping option appears, contact otakudiesel@gmail.com before ordering.

Processing and production

Standard orders are normally prepared for shipment within 3–5 business days after payment and receipt of the information needed to fulfill the order. Custom orders are normally prepared within 7–10 business days. Any different product-specific production time will be disclosed before purchase.

Business days exclude weekends and public holidays. Processing time is separate from carrier transit time.

Shipping costs and delivery estimates

Shipping charges and available services are displayed at checkout before payment. Carrier delivery estimates are estimates unless an option expressly guarantees delivery. We do not promise arrival by an event date unless we confirm it in writing.

When an order ships, we send a shipping confirmation. Tracking is provided for services that include it.

Delays

If we cannot ship within the timeframe promised at purchase, we will notify you, provide an updated shipment date when available, and offer the choice to consent to the delay or cancel for a full refund of the unshipped merchandise and associated shipping charges. We will cancel and refund when legally required if consent is not obtained.

Address corrections

Check your shipping address carefully. Email otakudiesel@gmail.com immediately if a correction is needed. We will try to update it before shipment but cannot guarantee changes once an order is dispatched.

If a package is returned because the customer supplied an incorrect address or did not collect it, we will contact the customer about reshipment or an applicable refund. Any additional shipping charges will be explained before reshipment. If the error was ours, we cover the correction.

Lost packages and delivery problems

If tracking stops updating or shows delivery but you cannot find the package, email us with your order number. Check the delivery location and household members if practical. We will work with you and the carrier to investigate and arrange an appropriate resolution. A carrier delivery scan does not automatically end our investigation.

International orders

If international shipping is offered, customs processing may affect delivery. Any import duties, taxes, or handling charges not collected at checkout may be payable by the customer where permitted by law. We will disclose known charges and any checkout collection before purchase.
