Our Services

Pre-production Inspection

The Pre-Production Inspection (PPI) is completed after the identification and the evaluation of your vendor / factory and right before the beginning of the actual mass production. It can be completed at the factory or at the vendor office. The aim of the PPI is to make sure your vendor has well understood your requirements and the specifications of your order and is prepared for its production.

Initial Production Inspection

The Initial Production Inspection (IPI), also called First Article Inspection, usually happens right after the manufacturer starts producing the first mass production samples. We will send our inspector when 1% to 10% of your ordered quantity has been produced. This product inspection is usually performed at the factory.

During Production Inspection

The During Production Inspection (DPI) will take place during production between 20% and 80% of the manufacturing process. We check packed and ready to go products.

Pre-shipment Inspection

The Pre-Shipment Inspection (PSI), also called Final Random Inspection (FRI) or Finished Quality Control, will take place when at least 80% of the products are ready and packed into export cartons. You can of course specify when booking with us if you want 100% of the products to be ready for this inspection. The pre shipment inspection will take place at the factory, or in some cases, it could even take place at the forwarder’s premises or at the pier.

Container Loading Supervision

The Container Loading Supervision (CLS) will take place right before the vendor / factory / manufacturer is supposed to load the goods inside the container and also during the loading process. This inspection usually takes place at the factory. It can also be performed at your forwarder’s premises.

Defect Sorting Service

The purpose of the Defect Sorting service is to sort out as many products as possible on known issues (ex: specific cosmetic defects, function problems, or packing imperfections, etc.) during the number of man-days allocated. Other checks will not be done during this inspection.

Production Monitoring

You might want to be sure that the operators are well trained for your product but you don’t have time to handle the Quality Control yourself. We can provide you a flexible solution, our Production Monitoring.

Factory Evaluation

The Factory Evaluation (FE) should be performed before the buyer places an order with a new vendor and only takes one day. The Factory Evaluation is done at your manufacturer’s premises, anywhere in Asia.

Extensive Factory Audit

The Extensive Factory Audit (EFA) is usually performed before you intend to place an order with a new vendor. This factory audit is usually performed during two days. This factory audit is performed at your manufacturer’s premises.

Corporate Social Audit

The Corporate Social Audit (CSA) should be performed to ensure that you are doing business with factories in which social rights are respected.

Laboratory Product Testing

TOPWIN’s core service is Quality Control for consumer goods in Asia, which consists of Product Inspectionsand Factory Audits in Asia. While we do not personally do lab testing, we can help you get your product tested as per international safety standards and mandatory norms.

Other Services

All shipment products inspect according to international quality standard by the experienced inspector to control the whole lots quality usually for your special/ expensive/ high risk product. The 100% trust for product.

15. What happens if non-confirming goods are found when the shipment arrives?

It is extremely rare that non-conforming goods make it out of the factory if TOPWIN is hired. In the vast majority of cases, the root cause turns out to be damage during shipping or shipments were approved after a failed inspection and the buyer trusts the factory (who was likely supposed to rework the goods) enough to ship without having performed a re-inspection or a defect sorting service. Therefore, we highly recommend you to book re-inspection or defect sorting service after a failed inspection and to work with your shipping partners to insure the product against damage in transit. TOPWIN guarantees that we will inspect the product to the standard and methods approved by the client (including chosen sampling size). In the event our inspectors do not follow the agreed standards, TOPWIN will make a refund of up to 5 times the price of the inspection.

16. Why doesn’t TOPWIN provide a warranty on behalf of the supplier?

As it is not economically viable for most clients to inspect every unit in the order, AQL tables determine the number of units to be inspected which will yield a statistically reliable sample size. In other words, if the inspection on the randomly selected lot goes well, then it is statistically unlikely that defects will be found in the rest of the order. For the sake of example, say there are 100 master cartons in an order and 50 units per master carton for 5000 units total. Our inspectors would open at random a select set of master cartons (the square root of the total number of cartons) and further select at random a set of individual units inside that master carton as per sampling size chosen by the client. However, if the supplier knew they had a few dozen defects and packaged the defects all together in one section of one master carton, then it would be statistically unlikely that our inspector would find this pocket of defects. For this reason, TOPWIN does not provide a warranty on behalf of the supplier. But we stress to our clients that they should have robust POs, warranty terms and payment terms with their suppliers that protect the interests of the client. Negotiating such terms with the supplier is outside of the scope of our business at TOPWIN, but our endorsed Partners can help with the negotiations and contract review.

17. Where do I send my approved samples of my product?

In order to save time and money, we advise you to send it directly to your factory, in a sealed package to our attention. In case you do not trust enough your factory or vendor for this, you can send it to our closest office. To know to which office to send it, check our offices address on your dashboard or contact your account manager. How to decide sample plan and inspection level against your products?
