Yes, as a manufacturer, we maintain strict control over product quality. While we may collaborate with other factories to meet production capacity demands, we implement rigorous quality checks to ensure all parts meet our high standards for quality and consistency. Furthermore, we provide a 2-year warranty, offering returns or replacements in case of any quality issues.

Shipping costs are primarily determined by two factors: weight and destination country. Weight is the key factor—shipping a 15kg product typically costs about twice as much as shipping a 5kg product. All products are shipped via DHL Express air freight.

Yes, customs duties may apply, depending on the policies of your country. Typically, DHL will handle the customs clearance process on your behalf and charge you for any associated fees.

To minimize logistics and management costs while offering the best prices to our customers, we are currently shipping from China. We are actively working on plans to establish a warehouse in North America.

The reason is mainly because of the large variety and quantity of items in our inventory. Taking photos for every single part requires significant time and manpower. However, even without images, all our product descriptions and part numbers are accurate and reliable, so you can be confident that you’re ordering the correct part.

Yes, absolutely! We highly welcome bulk orders — in fact, large-scale production and wholesale is our specialty. We support custom designs based on your drawings, flexible material options, and provide very competitive pricing (often around one-fourth of typical retail). Our bulk supply is not limited to heavy equipment parts, but also includes truck and automotive components, and even certain marine applications. Please feel free to contact us for details!
