We ship within the 48 contiguous United States. We use USPS, UPS & FedEx for our shipping solutions. Large shipments, 50kg or more may be shipped by freight. Shipping costs are automatically calculated by the carrier during checkout. Any additional shipping charges due to incorrect or incomplete address information or delivery refusal will be at the customer’s expense.

All orders are shipped “Signature not required” unless otherwise requested (additional charges may apply).

All orders are shipped directly from our Henderson, Nevada warehouse.

Additive Plus does NOT charge any additional fees beyond what is stated on the order invoice.

We offer free shipping within the US for orders totaling US$200 or more before tax.

We reserve the right to choose the most economical shipping method. The shipping fee coverage for the free shipping option is limited to shipping services with charges up to US$50.

Free shipping does not apply to bulk or custom orders with discounted pricing.
