Shipping Policy
Last updated: October 29, 2026
This page explains the journey from order confirmation to delivery for zenviroze purchases. zenviroze is operated by Chongqing Changzhiran Network Technology Co., Ltd.
Shipping cost
Standard shipping to supported United States addresses is free on orders of US$39 or more and costs US$3.99 on orders below US$39. An Express option is available at US$5.99 where displayed at checkout. We currently ship to the United States. Checkout confirms which methods are available for your complete address. If checkout does not offer shipping to that address, please contact us rather than selecting an inaccurate destination. The US$5.99 Express option does not carry a separate guaranteed delivery deadline in this policy; review any estimate displayed at checkout before selecting it.
Processing and transit are separate
Orders are normally processed within 1–3 business days after payment confirmation. Standard transit is estimated at 7–15 business days after dispatch; processing time is additional.
Business days exclude weekends and applicable public holidays. Transit begins when the order is dispatched, not when it is placed. If an item has a different production or preparation requirement, that information must be disclosed before purchase. We will contact you if an unexpected delay affects your order.
Where orders are fulfilled
Orders may be fulfilled from our own or partner facilities according to inventory availability and delivery destination. The dispatch location may differ from our business address, and an order may travel internationally. Our business address does not imply local dispatch in your country.
After dispatch
A shipping confirmation will provide available tracking information. A carrier’s first scan may not appear immediately. Use the tracking details in your confirmation, or email us with your order number if you cannot find them or the shipment has stopped updating.
Address changes and failed delivery
Please provide a complete, accurate delivery address and a reachable contact number where requested. Tell us immediately if you find a mistake. We will try to help before dispatch, but cannot guarantee that a carrier can redirect a shipment already in transit. If delivery fails, contact us so we can review the carrier’s information and explain the available next steps and any properly disclosed, lawful costs.
Delays, missing parcels and damage
Weather, customs checks, carrier interruptions and seasonal demand can affect transit. Estimates are not guaranteed delivery appointments. If we cannot ship within the promised time, we will notify you, provide a revised estimate and offer the choice required by applicable law: agree to the delay or cancel the unshipped goods for a prompt refund.
If a parcel appears lost or is marked delivered but cannot be located, contact service@zenviroze.com with your order and tracking details. We will investigate with the carrier or fulfillment partner; a “delivered” scan alone is not a reason to automatically reject a claim. Where an order is not delivered, we will provide an appropriate resolution in accordance with applicable law.
For damage on arrival, tell us promptly and include photographs of the packaging and item where reasonably possible. We will arrange an appropriate replacement, refund or return solution without charging you costs that we are responsible for.
Customs and import charges
International shipments may be inspected by customs and may attract import taxes or duties. Charges collected through our checkout are shown before payment; the destination authority may assess additional charges not collected there. Contact us before ordering if you need clarification about the shipping arrangement for your destination.
Returning a delivered order
Our return warehouse is in China. Please follow the Return & Refund Policy and obtain the specific return address from customer support rather than sending a parcel to our business address.
Nothing in this policy limits any mandatory consumer rights, remedies, warranties or withdrawal rights that apply to your purchase. Where applicable law provides greater protection or requires a faster refund, that law takes priority.
