At Essential Oxygen, we make every effort to ensure that your purchase arrives in perfect condition and shipping is fast and efficient.


At this time, we offer shipping of wholesale purchases to U.S. customers only. We are not able to ship outside the United States due to additional taxes and fees imposed by customs. If you are an international customer, you must arrange for order pick up at our warehouse in Fairfield, California.

We offer shipping through UPS and USPS carrier services. The shipping rates are calculated based on weight and distance to your address from our warehouse and are determined by the carrier. Essential Oxygen does not profit from shipping fees and shipping costs are passed through to the carrier.


Because shipping liquid products can be more expensive due to their weight, Essential Oxygen has a tiered cost structure to help offset your shipping costs.This tiered structure ensures the highest level of product quality and customer service.

Tiered Pricing Structure

Tier 1: Purchases of $325+ automatically qualify for UPS Ground shipping flat rate price of $25 to any continental U.S. location, not including Alaska and Hawaii (after promotions and discounts are applied).

Tier 2: Purchases of $750 or more automatically qualify for free UPS Ground shipping to any continental U.S. location, not including Alaska and Hawaii (after promotions and discounts are applied).

Please allow 3 – 10 business days for your order to arrive, depending on your location and selected carrier. Orders are processed Monday – Friday 7am to 3:30 pm PST (excluding holidays). Orders placed after 3:30 pm on Fridays and over the weekend will be processed promptly the following Monday.


We want you to be completely satisfied with your experience. If you are unhappy with your order for any reason, please contact us within 30 days from your purchase date at and reference your order number.
