At FlowTheory SD, we design, manufacture, and ship 3D-printed automotive accessories and custom products from Southern California.

1. Shipping Destinations

We currently ship within the United States only. International shipping is not available at this time.

2. Production and Processing Times

Our standard production and order processing window is 3–5 business days, excluding weekends and holidays.

This timeframe begins after payment is confirmed and all information required to manufacture the product has been received.

Orders requiring additional customization, design changes, or special materials may take longer. We will communicate significant production delays or revised timelines when necessary.

Production time is separate from shipping transit time.

For example, an order may require 3–5 business days for production before being handed over to the shipping carrier.

3. Shipping Methods and Rates

We currently offer:

USPS Ground Advantage
UPS Ground

Available services and calculated shipping rates are displayed during checkout.

Shipping charges are based on package weight, dimensions, destination, and carrier pricing.

4. Delivery Estimates

Estimated delivery dates shown at checkout are estimates rather than guarantees.

Delivery may be affected by weather, carrier delays, holidays, and other circumstances outside our control.

Please allow for our production window in addition to the carrier's transit time. If a checkout delivery estimate does not account for production time, the combined timeframe may be longer than displayed.

5. Tracking Information

Once your order ships, you will receive a shipping confirmation email containing tracking information when available.

Tracking information may take additional time to update after the carrier receives the package.

6. Shipping Address Accuracy

Customers should verify their shipping information before completing checkout.

If you discover an error, contact us immediately at https://flowtheorysd.com/pages/contact.

We will attempt to correct the address before shipment when possible.

7. Lost, Damaged, or Delayed Shipments

If your package is lost, damaged, or significantly delayed, contact us with your order number and a description of the issue.

For damaged deliveries, photographs of the product and packaging are helpful.

We will investigate the issue and provide an appropriate resolution, including any remedies required by applicable law.

8. Multiple Products

Orders containing multiple products may require additional processing time.

If an order must ship in separate packages, we will communicate any additional shipping charges before charging them.

9. Custom-Manufactured Products

Custom speaker adapters and personalized products may require confirmation of vehicle information, speaker model, measurements, or other specifications.

Production may be delayed until all required information has been provided.

Customers should ensure that submitted specifications are accurate.
