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
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.
4. Customs and Taxes
4.1 How are customs handled by OpenELAB for import or export?
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?
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?
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.
