No. We supply single components as well as volume orders. Pricing is based on availability and market value at the time of quotation.

Standard quotations are valid for 30 days. For items with limited availability, the quote may specify a shorter period. If your quote expires, contact us – we can often re‑issue at the same terms if the part is still available.

Our main warehouse is located in Xiamen, China. Depending on stock availability, some orders may ship from partner locations in Europe or the US to reduce transit time.

The customer is responsible for all import duties, taxes, and customs fees. These are not included in our prices. We recommend checking with your local customs authority before ordering.

We warrant that products are free from defects in materials and workmanship at the time of shipment. If a failure occurs under normal use within 12 months, we will replace the item or refund the purchase price (our choice). The warranty does not cover damage from improper installation, misuse, or unauthorized repair.

For returns under warranty or change‑of‑mind returns (within 30 days, unused), contact dalianmao222@outlook.com with your order number. We will issue a Return Merchandise Authorization (RMA) number and provide return instructions. Returns without an RMA are not accepted.

If the return is due to our error (wrong item, defect), we cover return costs. For change‑of‑mind returns, the customer pays return shipping. In warranty cases where the item is found defective, we refund the original shipping and pay return shipping for the replacement.
