SuperFiber Shipping Policy

Where We Ship and Processing Time

Last updated: September 30, 2026

We ship to addresses in the United States. We do not currently ship internationally.

Orders are processed and handed to the carrier within 1 to 3 business days after you place them. Business days are Monday through Friday, excluding U.S. federal holidays. Orders placed after midday Eastern time, on weekends or on holidays begin processing the next business day. During busy periods, such as sales and holidays, processing may take longer, and we will note any delays on the Site.

You will receive an email confirmation when you place your order and a shipping confirmation with tracking information once it ships.

Shipping and Delivery

Shipping costs and delivery estimates appear at checkout before you pay. Delivery time starts after your order has been processed and handed to the carrier.

Delivery dates are estimates, not guarantees. Carrier delays, weather, holidays and other events outside our control can affect delivery times. Taxes, where required, are calculated at checkout based on your shipping address.

If your order includes more than one product, it may ship in more than one package.

Tracking, Address Errors and Problems with Delivery

Tracking

We email tracking information when your order ships. Tracking can take up to 24 hours to update after the carrier receives the package.

Address accuracy

Please double-check your shipping address at checkout. We ship to the address you provide, and we are not responsible for orders sent to an incorrect or incomplete address that you entered. If you notice a mistake, contact us right away. We can change the address only if the order has not shipped. If a package is returned to us because of an address error, we can re-ship it once you pay the additional shipping cost.

Lost, delayed or damaged packages

If your tracking shows delivered but you do not have your package, first check with neighbors and your building's mail area. If you still can't find it, or if your order is late or arrives damaged, contact us within 14 days of the delivery date or expected delivery date. See our Return Policy for how we replace or refund orders with a shipping problem.

Storage on arrival

Our products should be stored in a cool, dry place. If a package has been left in extreme heat, bring it inside promptly.

SuperFiber Return Policy

All Sales Are Final

Last updated: September 30, 2026

All purchases from superfiber.com are final. Because our products are dietary supplements that you take internally, we cannot accept returns or exchanges, and we cannot offer refunds for products you have changed your mind about, opened, used or don't like. This keeps every product we send to customers safe and sealed.

We want you to be happy with your order. If something is wrong with it, see below, and we will make it right.

Damaged, Incorrect or Defective Orders

If your order arrives damaged, defective or incorrect, or if it never arrives, contact us within 14 days of delivery (or of the expected delivery date, for a missing package). Email hello@superfiber.com with:

• Your order number
• A description of the problem
• Photos of the product and the packaging, if the order arrived damaged or incorrect

After we review your request, we will send a replacement or issue a refund to your original payment method, at our discretion. You do not need to send the product back.

If you have a bad reaction to a product, stop using it and talk to a healthcare provider. Then contact us so we can help and document the issue.

Order Cancellations and Subscriptions

Cancelling an order

We can cancel or change an order only if it has not yet shipped. Email hello@superfiber.com as soon as possible after ordering. Once an order has shipped, it cannot be cancelled.

Subscriptions

You can skip, change or cancel a subscription at any time through your account or by contacting us. Make the change before your next scheduled shipment to avoid being charged for it. Subscription shipments that have already been processed are final, like any other order. If you cancelled on time and were still charged, contact us and we will refund the charge.

Refunds, Other Retailers and Contact

Refunds

Approved refunds go back to your original payment method. Your bank or card issuer controls how long the credit takes to appear, which is usually 5 to 10 business days after we process it. Shipping charges are refunded only when the problem was our error.

Purchases from other retailers

This policy applies only to orders placed on superfiber.com. If you bought SuperFiber products from Amazon or another retailer, that retailer's return policy applies, and you should contact them directly.
