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.
