Terms & Conditions of Sale

Except as provided in a separate written agreement, such as a Product Sale Agreement, negotiated by the parties and executed by authorized representatives of Seller and Buyer, each sale of Products or Services by Seller shall be governed by these Terms and Conditions of Sale ("Terms"). "Seller" refers to Airgas USA, LLC or one of its Affiliates, the name of which will be reflected on the invoice for the Products or Services purchased by Buyer. "Affiliate" refers to an entity that directly, or indirectly through one or more intermediaries, controls or is controlled by, or is under common control with Airgas USA, LLC. "Buyer" refers to the purchaser of Products or Services from Seller. "Product(s)" refers to any goods or other items of tangible personal property sold by Seller to Buyer. "Services" refers to any service provided by Seller. Seller’s acceptance of any order is expressly subject to Buyer's assent to each and all of the terms and conditions set forth herein. These Terms represent the entire agreement with respect to the sale of Products and Services and, except as provided in a separate written agreement as set forth above or in a separate document that expressly incorporates these Terms, supersede all prior or contemporaneous written/oral communications between the parties and information in any Seller literature, website or catalog, and override and exclude any other terms and conditions stipulated, incorporated or referred to by Buyer, including without limitation any Buyer purchase order, and any prior course of dealing between the parties.

1. AGREEMENT. Buyer shall not purchase any Products or Services on Seller’s website (the "Site") unless Buyer is an authorized, registered user of the Site. By purchasing any Products or Services on the Site, Buyer accepts, without limitation or qualification, these Terms governing such purchase. If Buyer does not agree and accept, without limitation or qualification, these Terms, Buyer may not purchase from the Site. If these Terms are construed to be an offer, this offer expressly limits acceptance by Buyer to these Terms and notice of objection to any different or additional terms is hereby given. Seller reserves the right to modify and update these Terms at any time by e-mail, changing these Terms on the Site or other commercially reasonable methods, and Buyer should carefully review these Terms before each purchase. These Terms, as modified, shall apply to all purchases of Products and/or Services on or after such update.
2. TITLE TO PRODUCTS. Until Buyer pays Seller in full, title to the Products shall remain in Seller's name and Seller shall have a purchase money security interest in the Products. If Buyer shall default in any payments, Seller shall have all the rights as holder of such title or as such secured party under the Uniform Commercial Code and/or any other law then in force; and Seller may, in addition, retain as rental any payments received by Seller on account of the purchase price of the Products, whether Buyer's default shall have occurred before or after delivery. If Seller repossesses the Products, Seller may resell the Products after ten (10) days' prior written notice to Buyer. Seller may file one or more financing statements to perfect its security interests. If necessary, Buyer shall execute such financing statements upon request. Buyer shall not cover, modify or remove any identification or other indicia of Seller’s ownership on any rental equipment. Title to all rental equipment shall remain in Seller's name.
3. CYLINDERS. Unless otherwise specified, cylinders, fittings and caps covered by these Terms are rented by Seller to Buyer at Seller’s current daily rates, beginning with the date of delivery. Rental fees are assessed as of the last day of each month or at the start of each annual lease period, as applicable. Seller shall monitor cylinder deliveries and returns hereunder. Each invoice for rental fees will show a number of cylinders outstanding as of the date of such invoice. The balance shown on any such invoice shall be deemed correct and conclusive unless Buyer submits a notice of dispute in writing to Seller within ninety-five days after the date of such invoice. Buyer shall continue to pay rental fees on all cylinders until (i) such cylinders have been returned to Seller or (ii) payment has been made with respect to loss or damage thereto as set forth below. Buyer shall keep all cylinders in secure locations. Cylinders shall remain the property of Seller. Each refillable cylinder may be subject to a cylinder deposit fee, as established by Seller from time to time. Seller will refund the deposit fee when Buyer returns the cylinder, unless the cylinder's condition is deemed to be unfit for reuse, as determined by Seller, which determination shall be irrefutable ninety-five days after the cylinder was returned to Seller. Buyer shall not permit cylinders or other storage containers furnished hereunder to be filled with any product not furnished by Seller and such cylinders shall not be used by Buyer for purposes other than the storage of gas products purchased from Seller or the return and reclamation of certain gases (e.g., refrigerants). Buyer shall return, in a good and non-contaminated condition, all cylinders, with valves closed, complete with caps and fittings and shall pay Seller the replacement value of any contaminated, lost or damaged cylinders, caps or fittings. Payment by Buyer for damaged, lost or destroyed cylinders shall not give any ownership interest in the cylinders to Buyer. BUYER ASSUMES ALL RISK AND LIABILITY ARISING OUT OF THE PRESENCE, STORAGE, TRANSPORT OR USE OF ANY LOST CYLINDERS.
4. ONLINE PRICING. Online pricing may not be available at all of Seller's retail branch locations. Online pricing may not be valid for Buyer's locations outside of the contiguous 48 United States, including for Buyer's locations in Alaska, Hawaii, Guam, American Samoa, Puerto Rico or the U.S. Virgin Islands.
5. TERMS OF PAYMENT. Unless otherwise specified, Buyer shall make payment in full by the thirtieth day following the date of invoice. In the event Buyer fails to make any payment when and as due, Seller may, at Seller’s option, exercise any one or more of the following (in addition to any other remedies available to Seller): (a) cease all Product deliveries; (b) require Buyer, as a condition of receiving deliveries, to prepay for such deliveries and pay past due amounts as specified by Seller; (c) collect from Buyer on any delinquent balance interest at the rate of one and one-half percent per month or, if less, the maximum rate permitted by law; and/or (d) remove any cylinders and/or other containers provided by Seller. If Buyer requests payment terms other than cash or cash on delivery (COD), Buyer represents that the purchases are made for business, commercial or agricultural purposes and not for personal, household, or family use. If Buyer has received credit approval from Seller, continued open account credit is subject to Seller's assessment of Buyer's financial condition and ability to pay. Buyer represents and warrants that Buyer is and shall remain solvent until Seller receives payment in full for the Products and/or Services. If Seller employs any collection agency or attorney to collect any amount due Seller, and/or to repossess any Products, Buyer shall pay all collection fees, attorneys' fees, and court costs, in addition to the amount otherwise unpaid.
6. CHARGES. Buyer shall pay (a) Seller’s itemized charges and (b) any surcharges that Seller may assess due to (i) extraordinary, emergency or other unanticipated increases in the cost of manufacturing, purchasing, supplying or distributing Product and/or (ii) Product shortages (collectively, "Charges"). Charges may be amended or others may be added at Seller’s discretion. None of the Charges represents a tax or fee paid to or imposed by any governmental authority, and all of the Charges are retained by Seller. Seller may not have specifically quantified the relationship between such Charges and the actual costs associated with such Charges, which can vary by Product, service, time and place, among other things.
7. DELIVERY. (a) Delivery method for all orders shall be as stated on Seller’s delivery ticket and/or invoice and, if not stated therein, shall be EXW (Incoterms 2020) Seller's branch or warehouse, or as otherwise determined by Seller. (b) Delivery date(s) are determined from the date of each order of Products and are estimates of approximate dates of delivery, not a guarantee of a particular day of delivery. Business days are Monday–Friday and orders placed before 3 pm typically ship the same day. Holidays, Saturday and Sunday, branch closing time, regional availability, and the customer's unloading point may not be factored into the estimated shipping timelines and may be subject to change. Additionally, orders placed before 3 pm on business days typically ship the same day; however, for orders received after 3 pm, the ship date that is visible on the site will be delayed an additional day because post-3 pm orders will not be considered same-day. For a more specific delivery ETA, please call us at (866) 935-3370, or send us an email at wecanhelp@airgas.com. (c) Seller reserves the right to decline or cancel any order at any time prior to shipment. (d) Seller or its representatives shall usually make deliveries of Product(s) on regular business days between the hours of 8 am and 5 pm or at other hours upon agreement of the parties. Buyer shall pay all additional expenses incurred by Seller as a result of deliveries at other hours or any other special delivery. Please note these shipping method explanations: Next-Day delivery arrives the next business day after an order has shipped. An order shipped out on Monday with Next-Day delivery would be received on Tuesday. But an order shipped out on Friday with Next-Day delivery will be received on Monday. Second-Day delivery arrives by the end of the second business day after an order has shipped. If an order is shipped out on Tuesday, it will arrive on Thursday. If it is shipped out on Thursday, it will be received on Monday. Standard Shipping arrives in one to five business days after the shipment. (e) Deliveries made during a strike or other labor disturbance affecting Buyer shall be at Seller’s sole option. If Seller does deliver during a strike or labor disturbance, then, notwithstanding anything to the contrary contained in these Terms, Buyer assumes the entire risk and agrees to indemnify Seller from and against all costs, damages and losses arising out of any such delivery. (f) Seller may refuse to deliver Product(s) to any of Buyer's locations if Seller reasonably believes that such location is unsafe or violates any applicable law or regulation, and Seller shall not be liable for such refusal to deliver. (g) Deliveries of Product shall be measured by Seller using the method typically used by Seller for the type of delivery made.
8. RETURN OF PRODUCTS. No Products shall be returned to Seller without Seller's written authorization. Buyer shall pay a fifteen percent (15%) restocking Charge on all Products returned to Seller, except for returns provided for under Section 11 hereof.

9. WARRANTY. Seller warrants that, at the time of delivery, all gas Products furnished hereunder will comply with Compressed Gas Association (CGA) guidelines. Any other Products sold by Seller will conform to Seller’s or manufacturer’s standard specifications.

Seller warrants that the Services shall be performed in a good and workmanlike manner. SELLER SPECIFICALLY DISCLAIMS ANY OTHER EXPRESS OR IMPLIED STANDARDS, GUARANTEES, OR WARRANTIES, INCLUDING ANY WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR NON-INFRINGEMENT AND ANY WARRANTIES THAT MAY BE ALLEGED TO ARISE AS A RESULT OF CUSTOM OR USAGE.

ALL CLAIMS BY BUYER HAVING ANYTHING TO DO WITH THE SUBJECT MATTER OF THESE TERMS SHALL BE MADE IN WRITING WITHIN NINETY FIVE DAYS AFTER THE EVENT GIVING RISE TO SUCH CLAIM AND FAILURE OF BUYER TO GIVE SUCH NOTICE SHALL CONSTITUTE A COMPLETE WAIVER BY BUYER OF ANY SUCH CLAIMS AND DEFENSE FOR SELLER AGAINST ANY SUCH CLAIMS. AS USED IN THIS SECTION, THE TERM “BUYER” AND “SELLER” SHALL INCLUDE NOT ONLY THE PARTY TO THESE TERMS BUT ALSO ALL OF ITS AFFILIATES.
