1. Applicability.

These Terms and Conditions of Sale, henceforth referred to as the "Terms", oversee the transaction involving the sale of goods ("Goods") by Rotari™, Sierling, Inc., and/or our authorised distributors/resellers ("Seller") to you, the purchaser ("Buyer" or "you"). Regardless of any terms or conditions indicated on the Seller's webpage, advertising, and other related materials, these Terms shall regulate the business relationship between the Seller and the Buyer, collectively referred to as the "Parties". Any previous or contemporaneous understandings, agreements, negotiations, representations and warranties, and communications, whether written or verbal, are superseded by the issued confirmation of sale ("Sales Confirmation") and these Terms. Where there is any conflict with these Terms, these Terms shall take precedence.

2. Delivery.

(a) The Goods will be delivered within a reasonable timeframe following the issuance of the Sales Confirmation by the Seller. The Seller shall not bear any liability for delays, losses, or damages during transit.

(b) The Seller is responsible for delivering the Goods to a commercial shipping company of the Seller's choosing, utilizing the Seller's standard packaging and shipping procedures.

(c) The Seller reserves the sole discretion, without incurring liability or penalty, to make partial shipments of Goods to the Buyer. Each shipment will be considered a separate sale, and the Buyer is obligated to pay for the units shipped, whether the shipment constitutes a complete or partial fulfillment of the quantity agreed upon under these Terms.

(d) Delivery will be conducted on an FOB basis in Cleveland, OH. The Seller is committed to facilitating the delivery in line with the terms detailed on the face of the Sales Confirmation.

3. Non-Delivery.

(a) The quantity of any shipment of Goods as recorded by Seller on dispatch from Seller’s place of business is conclusive evidence of the quantity received by Buyer on delivery unless Buyer can provide conclusive evidence proving the contrary. The Seller shall not be liable for any non-delivery of Goods (even if caused by Seller’s negligence) unless Buyer gives written notice to Seller of the non-delivery within 30 days of the date when the Goods would in the ordinary course of events have been received.
(b) Any liability of Seller for non-delivery of the Goods shall be limited to replacing the Goods within a reasonable time.


4. Returns and Risk of Loss.

(a) Unutilized Goods may be returned to the Seller for a refund of the buying price within a thirty (30) day period from the purchase date. These unutilized Goods must be returned in their original packaging.

(b) The original shipping costs are not subject to a refund. The expense of shipping the Goods back to the Seller will be borne by the Buyer.

(c) Refunds will be issued to the original form of payment used during the purchase.

(d) Packages that are returned to the Seller's premises by a third-party shipping company due to inability to deliver the Goods as a result of no access, incorrect address, or other shipping issues, will be automatically refunded, excluding the shipping charges and subjected to a fifteen (15) percent restocking fee.

(e) Ownership and risk of loss are transferred to the Buyer upon delivery of the Goods to the shipping service provider. To secure the payment of the purchase price of the Goods, the Buyer hereby grants the Seller a lien on and security interest in all of the Buyer's right, title, and interest in the Goods, wherever they may be located, whether existing now or later, or acquired from time to time, as well as any additions to and replacements or modifications thereof, along with all proceeds (including insurance proceeds) thereof. The security interest granted under this clause constitutes a purchase money security interest under the California Uniform Commercial Code.

5. Inspection and Rejection of Nonconforming Goods.

(a) The Buyer is required to inspect the Goods within a seven (7) day period after receipt (referred to as the "Inspection Period"). Unless the Seller is notified in writing of any Nonconforming Goods during the Inspection Period, along with any reasonable written evidence or other documentation required by the Seller, the Buyer will be considered to have accepted the Goods. "Nonconforming Goods" refer to: (i) a product that is different from what was specified in the Buyer's Sales Confirmation; or (ii) a product whose label or packaging inaccurately identifies its contents. If the Seller is timely notified by the Buyer about any Nonconforming Goods, the Seller may, at its sole discretion, either (i) replace such Nonconforming Goods with conforming Goods, or (ii) credit or refund the Price for such Nonconforming Goods. The Nonconforming Goods must be shipped back to the Seller by the Buyer, at the Buyer's expense and risk of loss. The Buyer acknowledges and agrees that the aforementioned remedies are the exclusive remedies available to the Buyer in the event of delivery of Nonconforming Goods.

6. Price.

(a) The Buyer agrees to purchase the Goods from the Seller at the price ("Price") listed in the Seller's public price list, which is valid as of the date of the Buyer's purchase. The Buyer will be responsible for paying any applicable taxes and duties. Any available discount terms will be calculated based on the original Price.

7. Payment Terms.

(a) The Buyer is required to pay all amounts due to the Seller at the time of purchase through the Seller's e-commerce platform. The Seller reserves the right not to process and ship the Goods to the Buyer if full payment is not received at the time of purchase.

8. Limited Warranty.

(a) The Seller provides a warranty to the Buyer that for a period of thirty (30) days from the date of shipment of the Goods ("Warranty Period"), the Goods will align materially with the Seller's published specifications effective as of the date of shipment and will be free from significant defects in materials and workmanship. The Seller further assures that it holds valid ownership of the Goods, and the transfer of ownership to the Buyer is valid and free from any security interest, lien, or other interest that may negatively affect the Buyer.

(b) Apart from the warranty mentioned above, the Seller does not provide any express or implied warranty regarding the Goods, all of which are expressly disclaimed. This includes any (a) Warranty of Merchantability; (b) Warranty of Fitness for a Particular Purpose; or (c) Warranty of Title, whether implied by law, course of dealing, course of performance, usage of trade or otherwise.


(c) The Seller won't be held liable for a breach of the warranty unless: (i) the Buyer provides written notice of the defect, reasonably described, to the Seller within seven (7) days of the time when the Buyer discovers or should have discovered the defect; (ii) the Seller is given a reasonable opportunity after receiving the notice to examine the Goods and the Buyer (if requested to do so by the Seller) returns the Goods to the Seller’s place of business at the Seller's cost for the examination; and (iii) the Seller reasonably verifies the Buyer’s claim that the Goods are defective.

(d) The Seller will not be held liable for a breach of the warranty if: (i) the Buyer continues to use the Goods after providing such notice; (ii) the defect arises because the Buyer failed to adhere to the Seller’s oral or written instructions regarding the storage, installation, commissioning, use or maintenance of the Goods; or (iii) the Buyer modifies or repairs the Goods without obtaining the prior written consent of the Seller.

(e) Subject to the disclaimers above, the Seller shall, at its sole discretion during the Warranty Period, either: (i) repair or replace the defective Goods (or part thereof), or (ii) credit or refund the pro-rata contract rate price of such Goods, provided that, if the Seller requests, the Buyer shall return such Goods to the Seller at the Seller's expense.

(f) The limited remedies provided in this Section 8 represent the Buyer's sole and exclusive remedy, and the Seller's entire liability for any breach of the limited warranty.

9. Limitation of Liability.

(a) In no circumstances shall the Seller be held accountable to the Buyer or any third party for any loss of use, revenue, or profit, or any consequential, indirect, incidental, special, exemplary, or punitive damages. This applies whether these damages arise from a breach of contract, tort (including negligence), or any other cause, irrespective of whether such damages were foreseeable, and regardless of whether or not the Seller has been advised of the potential for such damages, and even if any agreed or other remedy fails to serve its essential purpose.

In no event shall the Seller's total liability, whether arising from or relating to the Goods, these Terms, or any other matter, and whether arising out of or related to contract, tort (including negligence), or otherwise, exceed three (3) times the total of the amounts the Buyer has paid to the Seller for the Goods sold under these Terms.

The above limitation on liability shall not apply to liability resulting from the Seller’s gross negligence or willful misconduct.

(b) The Buyer affirms that they have read and understood the specifications of the Goods as posted on the Seller’s website under the title “Compatibility.” The Seller is not responsible for any issues arising from incorrect installation or use of Goods, even if the vehicle is compatible. The Seller also disclaims liability for the use of Goods in extreme weather or road conditions.

10. Waiver.

(a) No deviation from any provision of these Terms will be considered effective unless it is explicitly stated in writing and signed by the Seller. The Seller's delay in exercising or failure to exercise any right, remedy, power, or privilege arising from these Terms should not be construed as a waiver of such rights. The partial or single exercise of any of Seller's rights, remedies, powers, or privileges under these Terms does not hinder any other or further exercise thereof, or the exercise of any other right, remedy, power, or privilege.

11. No Third-Party Beneficiaries.

(a) These Terms are exclusively for the advantage of the Parties involved, along with their respective successors and permitted assigns. Nothing within these Terms, whether explicitly stated or implied, intends to or will bestow any other person or entity with any legal or equitable right, benefit, or remedy whatsoever under or because of these Terms.

12. Governing Law.

(a) All matters emanating from or related to these Terms are governed by and interpreted according to the internal laws of the State of California, without regard to any choice or conflict of law provision, statute, regulation, doctrine, rule, or court decision (whether from the State of California or any other jurisdiction) that would impose the laws of any jurisdiction other than those of the State of California.

13. Submission to Jurisdiction.

(a) Any dispute or claim resulting from or related to these Terms, or any breach of them, will, at the election of either Party, be resolved through arbitration managed by the American Arbitration Association under its Consumer Arbitration Rules. A judgment on the award given by the arbitrator(s) may be entered in any Court in the State of California. The rules of the American Arbitration Association can be viewed at this location:

14. Notices.

Notices may be sent by personal delivery, nationally recognized overnight courier (with all fees pre-paid), facsimile (with confirmation of transmission), or certified or registered mail (with a return receipt requested and postage prepaid). Unless otherwise specified in these Terms, a Notice is considered effective only (a) upon receipt by the receiving party, and (b) if the party issuing the Notice has fulfilled the requirements outlined in this Section.

15. Severability

(a) In the event that any term, provision, or portion thereof in these Terms is determined to be invalid, illegal, or unenforceable in any jurisdiction, such determination shall not affect the validity, legality, or enforceability of the remaining provisions of these Terms or any other term or provision within these Terms. Furthermore, such finding of invalidity, illegality, or unenforceability shall not invalidate or render unenforceable the specific term, provision, or portion thereof in any other jurisdiction.
