How and when Additive Plus ships your order, tracking, delivery and processing times.
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 Gardena, California warehouse.
Additive Plus does NOT charge any additional fees beyond what is stated on the order invoice.
Shipping is charged on every order. Rates are calculated at checkout from live carrier rates, based on destination, package weight and the service you select.
Where no service is specified, we reserve the right to choose the most economical shipping method.
Bulk, freight and custom orders are quoted separately.
Cut-off time for overnight shipping is 11:00 AM (Pacific Time). Orders placed after this time will ship the next business day. Friday overnight orders will be delivered the following Monday.
As soon as your order is fulfilled, you will receive an email confirmation including your tracking number.
If a shipment is refused or cannot be delivered, the courier will return it to us. Additional shipping and reshipping charges will be covered by the customer. Please ensure someone is available to receive the package.
We aim to ship orders same day for orders placed by 12:00 PM PST. Processing time may take 24–48 hours depending on order specifications. Delays may occur and will be communicated.
Inventory is synced between the online store and warehouse. Rare sync issues may result in an item being out of stock after purchase. In this case, we will offer an alternative or refund.
Products marked as “Sold Out” are typically restocked within 1–4 weeks.
