Free samples are usually available for specific cases, but shipping fees are excluded. Feel free to reach out to your exclusive project sales staff for further details.

To address common part quality issues, we typically offer replacements—this helps avoid incurring excessive shipping costs.

For lightweight or precious metal parts, you may also return them to us for repair or rework.If you need a refund: please note that lightweight parts and products must be returned first. In most cases, we will ask for the defective parts to be destroyed.

We can ship to nearly all countries and have the capability to handle import and export procedures. However, for customers in Brazil and Turkey, we need to confirm whether they have the ability to manage customs clearance before proceeding with cooperation.
