China Inspection Services

These factors are based on the requirements of the customers.

Several factors are necessary to evaluate during manufacturing.

Each factor determines the quality of the product.

For manufacturers, abiding by these factors is necessary.

They are obligations that the supplier must not rule out. The production is considered fruitful if it fulfills the requirements.

Customers use different ways of knowing the quality of the production.

Each method is applied based on the type of the production in progress. One of these methods is the inspection of the products.

Inspection is an important part of any manufacturing process.

It allows you to have an insight into how the products are being manufactured.

This assesses whether the products are manufactured according to the requirements or not.

What Is China Inspection Services?

China is the biggest manufacturer of goods and the cheapest of all too.

But, if you’re hiring a supplier from China, then you should opt for china inspection services.

This is essential since you will need to know whether your products are manufacturing the way you or not.

Why Need Product Inspection In China Before Sending It To Amazon FBA?

Here’s why you need to have your products inspected in China:

1. Amazon May Suspend Your Listing

Quality parameters are why you should get your products inspected in China. Amazon has quality inspection parameters. These parameters test the quality of the product that Amazon will be accepting.

Having products un-inspected and shipping them to Amazon will result in low-quality products. As a result, people getting those products will ask for a refund. If your refund rate goes over 10%. It results in Amazon sending you a warning. You will have to take up your inventory from Amazon to separate the defective inventory. This will cut short your profit margin. Your repute will drop since the people will be refunding your products.

2. The Nature Of Manufacturing Process Always Yields Some Defects

You will face the situation of manufacturing defects during product manufacturing. This defect arises due to the exponential demand for the products. During manufacturing, mechanical failures can be the main cause of manufacturing defects. If the machinery isn’t working well it can make defective products. These products if left un-inspected can cause problems later in the market.

3. Supplier May Cut Corners

Several trading companies in the market pose themselves as manufacturers. Hiring these companies increases the chance of defective products.

Such companies send quality samples to the customers. They do so that they can get approval for shipments. These companies cut corners in the manufacturing process after they get approval. They do so to save material requirements that result in low costs.

Yet, when they bill the customers, they still include the market costs for the products. Leaving these products without an inspection can cause an issue for the shipment. The supplier can state that it was a mechanical fault that cannot be refunded.

Why Need Product Inspection In China Before Sending It To Amazon FBA

Should I Do An Inspection In The USA Or In China?

There are two choices that you can opt for when want to do inspection:

1. Inspect All Products Yourself

When the products are delivered, you will have to open them. Including every box and every sealed package. After the opening of all the products, you will have to test each product unit.

After the testing is done you will have to pack and seal it up again to send it to Amazon. If you have enough resources to do the inspection on your own then you can choose this option.

2. Pay For The Inspector To Go To Your Factory In China

This option saves you from the hassle of doing the inspection on your own. You can search the market for reliable Chinese product inspection services.

Afterward, you can ask them about other factors. This may include their service costs, get a quote, etc.

Later you can hire them for the inspection of your products that are being manufactured in China. This will help you save all the hassle of inspecting the products all by yourself.

This will also save you from using the extra resources needed in the inspection of the products.

You will save expenditures on extra resources for inspections and repacking. You can also hire inspectors to do the inspection. While focusing on other important aspects of the business.

What If I Don’t Live In The USA?

If you’re not residing in the USA, then it’s best for you to get a full shipment inspection company in China. You can also choose to have an inspector to go to China and inspect the shipment by himself.

This should allow you to cut the resources needed for inspecting at your place. Moreover, you can also instruct the inspector to assess products from different pools.

Not every manufacturer produces extra units. But, it is a common practice that manufacturers produce some extra products. They do so to replace the defective ones found during an inspection. You can even ask the inspector to bring a pool of extra manufactured products. This will help in assessing the products yourself.

Besides getting an inspector, you need to make sure to have accurate reports sent to you by the inspector. Reports are the only evidence of the inspection that took place. That is why you need to make sure that they are delivered.

How Much Does It Cost To Do Product Inspection In China?

In general, product inspection in China costs around $0.20 per unit.

For example, if you’ve got the least order of 10,000 products, it will cost you $2000 for the entire lot.

You will have to pay for the inspector’s fee as well. You can choose to get a certain number of products inspected if you want to save up on the cost.

Should I get Full Products Inspection or Partial?

Here is a comprehensive view of doing full and partial product inspections:

Partial Inspection – Many Defects Found

You can either choose partial inspection or complete inspection. During a partial inspection, the inspector can come across several defective products. For example, in a lot of thousand products, you find 15 defective products. Does it mean that you will find 150 defective products in a lot of 10,000 products?

This number can never be determined, and this is why it is risky.

Partial Inspection – Few Defects Found

An inspection can result in finding no defective products at all. It is probable that the products chosen for inspection will be ok. This is one of the primary drawbacks of conducting a partial inspection.

However, based on the inspection report, you will receive the products and send them to Amazon. After doing this it’s possible that customers will be refunding your products when they find out that they are defective.

Choosing a partial inspection can help drop the extensive cost of complete inspections. Since not all the products will be inspected, the risk of having defective products sold to customers is high.

This can result in the drop of your repute in the market. Why? Because you will be sending products with the label of “inspected.” Customers that would refund the products will put out a bad review for your brand. This will result in the loss of your market profile.

Full Inspection

Choosing full inspection can result in the use of extra resources. However complete inspection will provide accurate information about the products manufactured. You can get an accurate number of defective products. You can also ask the manufacturer to replace them.

Getting a complete inspection requires more financials as well as time. You cannot expect this inspection to get completed before its completion time. In doing so, you can cut corners yourself. This can be done by minimizing the number of evaluation factors for the products.

This will save you from the hassle of sending the products on Amazon and getting refunds. It will not result in losing your profit margin and repute in the customer segment. If you wish to save money, you can choose partial inspection. Choosing partial inspection will increase the risk of defective products reaching the market.

How Does An Inspection Report Look Like?

An inspection report has several elements that you need to consider. These elements include:

  • product category
  • the passing number of the products
  • failed number,
  • not applicable

These parameters are assessed for each manufacturing lot. The inspectors use this to provide insights on how well has the manufacturing been done.

The number of pages of the inspection report depends upon the inspectors. They will elaborate it by communication.

The inspection report covers important information about the products that have been manufactured. The customers can define product evaluation parameters as well as the inspectors.

Each parameter is assessed before putting in the report. Thus, the products may not be assessed on terms that are not meeting the standard requirements in the first place.

The compiled list of the parameters for inspection is evaluated using products that are already being sold in the market. It makes it easier to amend the evaluation list. The inspectors get a practical insight into the usage of the parameters.

Payment Terms For China Inspection Services

You should remain cautious when the time of payment comes for China inspection services.

If you are to pay the payment before the inspection, the inspector will not make an effort to provide you with an accurate inspection report.

In case you’re planning to keep in the entire payment after the inspection, it is possible that the inspector will not be motivated enough.

Also, he will complete the inspection in no amount of time so that he can get his payment.

So it is recommended that you decide the effects partition of the payment. You can give a 30% payment upfront and put a 70% payment after the inspection has been.

This will form a trust bond with your inspector. Since you will be paying 30% for the inspection cost upfront.

It will also allow the inspector to keep their workability in check. That is because they would need to have their remaining payment, and would work efficiently.

What Suppliers Do With Defects?

Suppliers can choose different ways and options for dealing with defective products.

They can place the products back with the inspected products. They do so without the inspector noticing.

This can give rise to the chance that a defective product will reach your customers. To mitigate it, the inspector should ensure that the defective products are not mixed with the good ones.

The suppliers can rework and repair defective products. Since they know what items were used in the manufacturing process, they can repair them again.

In case you decide on asking them for repairs, you will be required to pay additionally aside from the labor cost too. This is because you don’t have the tools to repair the products by yourself.
