Production Inspection Process:

Our Group service includes regular and thorough inspections throughout the manufacturing process, eliminating the need to employ additional quality control inspectors.

- Raw material before any production begins

- Pre-production samples to ensure specifications are being met

- In-process to confirm that standards are maintained

- Pre-shipping to ensure that the product arrives to the customer exactly as expected and is packaged

correctly to prevent any damage in transit.

   We can help operating split shipments, meeting the factory minimum quantity but ship them in 2 or 3 shipments with required gaps among. This allows you to move stock through your business without taking up space and capital.

We will arrange the subsequent shipments from our factory to your warehouse.

We can consolidate your small orders from multiple factories, delivering all at the same time to you or your customers,using the most cost-effective route available. At the time of order placement, we will offer details to you about the volume of each component part and what size container will be used.
