    Important Notice:

    • Before placing your order, please check the inventory location on the product page to confirm the delivery timeframes.
    • For products stored in the Shenzhen warehouse, we will ship them directly from Shenzhen, China.
    • If you place an order for products from both the U.S. warehouse and the Shenzhen warehouse, we will ship your order separately: the products from the Shenzhen warehouse will be sent from Shenzhen, and the products from the U.S. warehouse will be sent from the U.S. warehouse.

       

    3. International Warehouse

    Our products are stored in both our U.S. and Shenzhen warehouses to provide more flexible logistics solutions tailored to different regions and customer needs. On each product's description page, we indicate the specific warehouse location to help you better plan your purchase and delivery schedule.

    3.1 U.S. Warehouse

    For products stored in our warehouse in the U.S., we use either USPS or UPS for shipping, depending on the size of the package. Logistics within U.S. are very efficient, with an estimated delivery time of 3-7 business days, ensuring you receive your order quickly and conveniently.  

    3.2 Chinese Warehouse

    We will only arrange YunExpressexpress shipping from Shenzhen for orders with products in the Shenzhen warehouse worth more than €50. Orders directly shipped from our Shenzhen warehouse are handled by YunExpress. Given the complexities of international shipping, the estimated delivery time for these packages is around 10 business days, though this may vary slightly due to customs processes or other uncontrollable factors. Otherwise, the products will first be shipped from China to our U.S. warehouse and then shipped to the final destination. 

    To ensure that your order is delivered within your desired timeframe, we recommend reviewing the warehouse information provided on the product pages before placing your order and selecting the appropriate shipping option. If you have any questions or need further assistance, please don't hesitate to contact our customer support team—we are here to help you!   

     

    4. Customs and Taxes

    4.1 How are customs handled by OpenELAB for import or export?

    For shipments delivered to customers in the United States, OpenELAB will clearly declare the value of the goods on the customs form in compliance with U.S. Customs and Border Protection (CBP) requirements. Depending on the product value and origin, certain orders may be subject to import duties, taxes, or brokerage fees upon arrival, which are the responsibility of the recipient unless otherwise stated.
     We aim to minimize delays and ensure compliance, but OpenELAB does not guarantee exemption from U.S. customs charges.
      

    4.2 Are U.S. sales taxes included when the Customer places an order?

    OpenELAB collects U.S. state sales tax where legally required. The applicable rate depends on the shipping address and will be calculated at checkout.
     If no sales tax is charged at the time of purchase, you may still be responsible for use tax according to your state’s tax laws. OpenELAB is committed to complying with the U.S. Supreme Court's decision in South Dakota v. Wayfair, Inc. and applicable local regulations.
      

    4.3 Are there any other fees besides tax?

    Apart from sales tax, OpenELAB may charge shipping or handling fees, which will be clearly displayed before checkout.
     Please note that international shipments to the U.S. may occasionally incur customs clearance charges or carrier-imposed fees (e.g., by DHL, FedEx, or USPS). These charges are not controlled by OpenELAB and may vary based on the delivery carrier and U.S. import classification.


    Effective Date: September 16th, 2025

    At OpenELAB, we are committed to providing accurate product descriptions and delivering high-quality products. If you experience any issues with your purchase, please notify us within 30 days of the shipment date.

      

    1. Warranty Disclaimer

    Unless explicitly stated in a specific agreement or purchase order, OpenELAB makes no warranties—express or implied—regarding the fitness, suitability, or merchantability of any product for a particular purpose or special use.

      

    2. Warranty Policy

    Warranty Period

    The standard warranty period for products sold by OpenELAB is 12 months from the date of delivery.

    Under this warranty, OpenELAB will make a reasonable effort to repair or replace products free of charge if defects are due to issues with raw materials, design, or manufacturing.

    If the defect qualifies under this policy but falls outside the covered scope, reasonable charges may apply for repair or replacement.

    After the warranty period, support may still be available at a reasonable fee.

      

    Warranty Exclusions

    The warranty does not apply in the following cases:

    • The product is beyond the 12-month warranty period.
    • Damage due to misuse, improper maintenance or storage, or failure to follow the user guide or manual.
    • Issues caused by Force Majeure events (e.g., natural disasters, war, legal changes, etc.).
    • Unauthorized repair attempts by the customer.
    • The product is not defective but has been opened and is non-returnable by policy.

       

    3. Returns & Refunds

    If you're not satisfied with your purchase, you may be eligible for a return or exchange:

    • Return for Refund: Within 15 days of receipt (unopened).
    • Return for Replacement: Within 30 days of receipt (damaged or defective).
    • Exchange Window: Up to 30 days from receipt.

    Please email us at info@openelab.com for a return authorization before sending anything back.

      

    Return Conditions

    • Items must be in original, clean, and mint condition with packaging intact.
    • Returns of damaged, used, scratched, modified, or programmed items will not be accepted.
    • Include the receipt, a brief note with your name, order number, and reason for return.

      

    Shipping & Fees

    • Customers are responsible for return shipping to our warehouses in the US.
    • If a return is requested due to customer reasons (e.g., change of mind, incorrect order, etc.), both the original shipping cost and the return shipping cost will be deducted from the refund amount.
    • For returns due to customer reasons, we will generate and provide a return shipping label. 

       

    Payment Platform Fees

    For all refunds requested due to customer reasons, a standard service fee will be deducted from the refund amount, which is charged by the payment platforms. The specific fees are as follows:

    Shopify Payments: 2.9% + $ 0.3

    PayPal: 4.4%
