1. Where we ship
At present, we ship physical products to eligible U.S. delivery addresses from our U.S. fulfillment warehouse. Most U.S. destinations are intended to be covered, but certain remote or carrier-ineligible addresses are excluded. Serviceability and shipping charges are determined at checkout before payment. We do not make a general promise of shipping to every U.S. ZIP code or to other countries.
2. Shipping prices
| Qualifying order amount | Standard shipping |
|---|---|
| USD $1,000 or less | USD $60 |
| Over USD $1,000 | Free |
Threshold calculation: The qualifying order value is calculated after promotional discounts or voucher deductions, including applicable sales tax but excluding shipping charges. For example, an order whose qualifying amount is exactly USD $1,000 incurs USD $60 standard shipping; an eligible amount greater than USD $1,000 qualifies for free standard shipping. The shipping rate and all applicable taxes are shown before payment. Remote addresses may be ineligible even if the amount is above USD $1,000.
3. Delivery estimate
For in-stock products dispatched from our U.S. warehouse, estimated carrier transit time is 2–7 days after dispatch. This estimate does not include any time required to accept, prepare, or pack an order. Actual delivery may vary depending on address, carrier service, weather, and other operational conditions. We will provide shipping or tracking information when available.
The 2–7-day estimate does not begin when an early-access voucher is purchased, and it must not be read as a promise that unreleased products are ready to ship.
4. Preorders, inventory and delays
Sirius launch offers, early-access vouchers, and actual product orders are different transactions. A voucher is not a shipped physical product. For future preorders, expected shipment timing should be prominently provided on the product page and at checkout. If we cannot meet a promised shipment deadline, we will notify affected customers and offer legally required options, including cancellation and refund where applicable.
5. Taxes, customs and duties
For eligible orders shipped domestically from our U.S. warehouse to U.S. addresses, customers will not be asked to pay an additional import customs duty upon delivery. Applicable sales tax, if any, is separate and will be shown at checkout. We do not describe the products as legally "duty-exempt" merely because they are delivered from a U.S. warehouse.
6. Tracking, address issues and delivery problems
Please ensure that your shipping information is accurate. If an address needs correction, contact support@hengbot.com immediately; changes may not be possible after dispatch. If tracking shows an exception, a package is lost, or a shipment arrives visibly damaged, notify us promptly with your order number and details. We will investigate with the carrier and provide a remedy in accordance with our policies and applicable law.
7. Returns
Before shipping a product back, contact support to receive written return authorization and battery-safe shipping instructions. The present return and repair intake address is our Shenzhen office, China, not the U.S. fulfillment warehouse. Do not send a return until support confirms that address and the approved route. See our Return & Refund Policy for responsibility for international return shipping and any applicable remedy.
