Terms of Use

1. About these terms

These terms govern the use of the DuoMy Sensing website at duomy.com and any quotation, order or supply of goods arising from it. By browsing the site or sending an enquiry you accept them. If you are ordering on behalf of a company, you confirm that you are authorised to bind that company.

DuoMy Sensing supplies industrial sensors, micro automation components and related engineering services to business customers. The website is intended for commercial and technical audiences, not for consumer purchases.

2. Product information and specifications

We describe our products as accurately as we can, but specifications on this website are indicative and can change as products are revised. The binding specification is the one stated on your quotation, order confirmation or the datasheet revision referenced in it.

Installation guidance, application notes and selection advice are provided in good faith based on the information you give us. They do not replace your own engineering verification, and the responsibility for fitness for a particular purpose remains with the party specifying the installation.

3. Quotations and orders

A quotation is valid for 30 days unless stated otherwise, and is subject to stock and material availability at the time of acceptance. An order becomes binding when we issue a written order confirmation.

We may decline an order where the specification cannot be met, where the destination is subject to export restrictions, or where we cannot verify the commercial details of the buyer.

4. Prices, taxes and payment

Prices are quoted in US dollars and exclude freight, insurance, duties and any local taxes unless expressly stated. Prices may change before an order is confirmed; confirmed orders are not re-priced.

Standard payment terms are 100% in advance for first orders and 30 days net for established accounts, subject to credit approval. Custom tooling and made-to-order production may require a deposit.

5. Delivery and risk

Lead times are given in working days from order confirmation or drawing approval, whichever is later. They are estimates, not guarantees, although we will inform you promptly if a delay is likely.

Risk passes according to the Incoterm stated on the order confirmation. Where no Incoterm is stated, risk passes when the goods are handed to the carrier.

6. Inspection, returns and warranty

Please inspect goods on arrival and notify us of any shortage, damage or specification mismatch within 14 days. Returns require a written authorisation; goods returned without one cannot be processed.

Products are warranted against defects in materials and workmanship for 12 months from delivery, or as stated on the quotation. The warranty does not cover normal wear, incorrect installation, operation outside the published specification, unauthorised modification or damage in transit.

Where a valid warranty claim is accepted, we will repair or replace the product at our option. Liability under warranty is limited to the value of the affected goods.

7. Custom and OEM products

Custom ranges, housings, cable assemblies and private-label products are produced to the drawing approved by the customer. The customer is responsible for checking that drawing before production release. Custom items are non-cancellable and non-returnable once production has started, except where they fail to meet the approved drawing.

8. Intellectual property

The content of this website, including text, product photography, drawings and datasheets, belongs to DuoMy Sensing or its licensors and may not be republished commercially without permission. You may download and print pages for internal engineering evaluation.

Where we manufacture to your drawing or your part number, you retain ownership of your design. We retain ownership of our manufacturing know-how, tooling design and process documentation.

9. Limitation of liability

To the extent permitted by law, our liability arising from any order is limited to the value of the goods supplied. We are not liable for indirect or consequential losses, including lost production, lost profit or damage to third-party equipment, however arising.

Nothing in these terms excludes liability that cannot lawfully be excluded.

10. Export control

Products may be subject to export control regulations. The buyer is responsible for obtaining any required import licence and for complying with the export rules of the jurisdiction of dispatch.

11. Governing law and disputes

These terms are governed by the laws of the jurisdiction stated on the order confirmation. The parties will attempt to resolve any dispute through commercial discussion before commencing formal proceedings.

12. Changes and contact

We may update these terms from time to time; the version published on this page applies to new orders from the date of publication. Questions about these terms, quotations or an existing order can be sent to chao.open@gmail.com or +86 132 6709 1606.
