Shipping policy
Last updated: September 8, 2026
H3O orders from h3ofuel.com are sold by NUTRIVA LABS LLC and fulfilled through Supliful from the United States.
Where we ship
We currently ship to the 48 contiguous United States and Washington, DC. We do not currently ship to Alaska, Hawaii, US territories, APO/FPO/DPO military addresses or international destinations.
Processing and delivery times
Standard orders normally require 2–5 business days for processing before dispatch. Shipping transit time starts after the parcel is dispatched. Business days for these estimates are Monday–Friday, excluding US federal holidays.
| Method | Price | Transit after dispatch |
|---|---|---|
| Regular | $7 USD | 2–4 business days |
| Express | $13 USD | 1–3 business days |
Prices are per order. Including processing, the estimated total wait is 4–9 business days for Regular or 3–8 business days for Express.
Express shipping shortens the estimated carrier transit time; it does not remove warehouse processing time. These are estimates, not guaranteed delivery dates. Destination, carrier conditions, holidays and unexpected fulfillment delays can affect timing.
Supliful currently uses USPS services for domestic deliveries. Your shipment confirmation identifies the service and tracking details for your parcel.
Charges and subscription deliveries
Shipping charges are shown before you pay at checkout. Any applicable sales tax is also calculated and displayed at checkout. Product prices do not include shipping unless an offer explicitly says otherwise.
For subscriptions, shipping applies to each recurring delivery. Review the delivery frequency, product price and shipping charge shown when you subscribe.
Tracking and delays
We send tracking details to the email address used at checkout when your order is dispatched. You can also check your customer account. Tracking updates may not appear immediately after a label is created.
If your order has not been dispatched within the stated processing estimate, or has not arrived within the expected transit estimate, contact info@h3ofuel.com with your order number. We will investigate with our fulfillment provider or carrier and explain the next steps.
If we cannot ship within the promised timeframe, we will notify you, provide a revised estimate where available, and offer the applicable option to agree to the delay or cancel the unshipped order for a refund. We do not treat handing a parcel to a carrier as ending our responsibility to help resolve a delivery problem.
Address changes and cancellation requests
Check your delivery address carefully before paying. If you need to correct an address or cancel an order, email us immediately. Changes are possible only while the order can still be stopped before fulfillment; we cannot promise to change an order that is already being prepared or has been dispatched.
If a parcel is returned because the address supplied was incorrect or delivery was refused or unclaimed, contact us. We will explain the available resolution and any reshipping charge before you agree to it. This does not limit your applicable consumer rights.
Missing, damaged or incorrect deliveries
If tracking shows delivery but you cannot locate the parcel, check the delivery location and with members of your household, then contact us so we can investigate. For a damaged or incorrect item, keep the packaging and contact us with details and any helpful photos. Do not use a product with a broken or missing safety seal.
Our Return & Refund Policy explains returns, refunds and replacements. Product returns require instructions from our support team; do not send them to the company's registered office.
