Delivery and Shipping

Add some general information about your delivery and shipping policies.

Shipping Policy

Marine Cobra ships most orders within the United States using UPS Ground or a similar ground carrier. We work to process orders quickly and provide clear shipping options at checkout.

Order Processing Time

Most orders are processed within 1–3 business days, excluding weekends and holidays.

Some orders may require additional processing time due to product availability, supplier fulfillment, freight requirements, special handling, or inventory verification.

Standard Ground Shipping

Standard ground delivery typically takes 3–5 business days after the order has shipped.

Delivery times are estimates and may vary based on carrier delays, product availability, destination, weather, or other shipping conditions.

Shipping rates are calculated and displayed at checkout before payment is completed.

Free Shipping

Marine Cobra offers free standard ground shipping on eligible orders over $100.

Free shipping eligibility depends on product size, weight, destination, and carrier availability. Oversized, heavy, hazardous, special-order, or freight-required items may not qualify for free shipping.

If free shipping is available for your order, it will appear as a shipping option during checkout.

Shipping Restrictions

We currently ship to valid physical addresses within the United States.

We do not ship to P.O. Boxes. Please provide a valid street address at checkout.

Some products may have shipping restrictions due to size, weight, manufacturer requirements, hazardous-material classification, or carrier limitations.

Freight and Oversized Items

Large, heavy, oversized, or irregularly shaped items may require freight shipping.

Freight shipping charges are based on product size, weight, destination, and carrier availability.

When available, freight shipping options and costs will be shown at checkout. For items requiring a custom freight quote, we may contact you before processing the order.

Final shipping charges are shown at checkout or confirmed before shipment.

Tracking Information

When your order ships, tracking information will be sent by email when available.

Tracking updates are provided by the carrier and may take time to appear after shipment.

Damaged, Missing, or Delayed Shipments

Please inspect your order when it arrives.

If your shipment is damaged, missing items, or significantly delayed, contact us as soon as possible so we can help review the issue with the carrier or supplier.
