Suggestion: Watch the 10 minutes video tutorial before reading this article

Having your products lab tested is the only way to be sure that your imported goods are safe, and compliant with all applicable regulations.

Importing non-compliant products is illegal, and can result in financial ruin if your cargo is ever seized by the customs authorities – or a forced recall.

But, how do you go about to actually get your products tested? That question, and many more, are answered in this complete guide to product lab testing in China.

Keep reading, and learn how to find the right lab, keep the testing costs down and why a test report is not always enough.

Why do I need laboratory testing?

As you may know, many products are regulated by one or more safety standards or chemical restrictions.

For example, children’s products imported to the United States are regulated by the CPSIA – which requires importers to present verifiable test reports from an accredited third party.

As such, a lab test report is simply a document that proves that a product is compliant with the relevant regulations and standards.

When it comes to some product categories, lab testing is mandatory, but not for most. As such, obtaining a test report is, in many cases optional.

If lab testing is not always mandatory, why do importers still submit their products for compliance testing?

First, a product must always be compliant. A third party lab test is the only way to verify that the product actually is compliant. While non-compliant products may get through the customs, they may be subject to a check later on.

If it turns out that your products are non-compliant, they will be subject to a forced recall. In other words, total disaster for any startup or small business.

Second, and retailers are increasingly aware of product safety regulations, and require their sellers and suppliers to provide extensive compliance documentation.

Failing to provide the relevant compliance documentation, which is often not only limited to lab test reports, may result in your product listing being suspended, or failure to sell products at all.

What kind of lab tests do we need?

A lab test report often corresponds to a certain regulation, standard or chemical. For example, you can order a REACH SVHC, ASTM or CA Prop 65 test report.

Why can’t my supplier do the lab test?

Manufacturers lack both the expertise and, often expensive, equipment required to conduct lab testing.

That said, even if they do have the knowledge and equipment to handle lab tests, as a buyer, you cannot trust your supplier with reporting honest and undistorted test results.

When you work with an accredited and reputable product compliance lab, you can be sure that they provide accurate reports – even if the result is not in the supplier’s favor.

Should we expect the supplier to pay for the lab test?

Suppliers rarely pay for testing, especially not when the product is designed by the customer. That said, some larger manufacturers test certain materials, that they use for many different orders.

Ultimately, the importer always ends up paying for the lab test, as the testing costs add to the factory price.

How much should I pay for product testing?

The testing costs depend on the following factors:

a. The number of regulations and tests required

b. The number of products

c. The number of materials

d. The number of colors

For some products, such as toys and electronics, you must pay on a per design or SKU basis. Hence, two different SKUs, even with the same materials and components, must be tested.

However, when importing apparel, one test report per material might do. Hence, the final cost also depends on the type of product. Below follows a few cost examples:

T-Shirt100% Cotton Fabric, 2 colorsREACH$500
T-Shirt100% Cotton Fabric, 4 colorsREACH$800
Power bankLithium power bank, 1 modelLVD, RoHS$900
Teddy BearStuffed animal, 1 modelEN 71, ASTM$800

While an extra color or material may not double the cost of lab test, it can add on anywhere from 20% to 50%.

How can we keep the testing costs as low as possible?

As the costs are based on the number of regulations, SKUs, colors and materials, you can lower your laboratory testing costs by applying the following methods:

a. Limit the number of markets you enter at a given time (hence, you need to comply with fewer regulations).

b. Launch a lower number of SKUs

c. Use the same colors and materials on as many SKUs as possible

Can’t we just use one of the suppliers test reports?

While a suppliers existing test reports are crucial for assessing if they can produce compliant products, you can in most cases not use old test reports as proof of compliance of the products you order at a later date.

Showing outdated test reports, or those that cannot be linked to your products, can result in the goods being seized by the customs authorities.

Do I need to get my products tested in my own country?

No, you don’t need to get the products tested in your country, as long as the laboratory is accredited by the government authorities in your country.

As such, many importers prefer to use laboratories based in Mainland China and Hong Kong, as it makes sample submission much faster.

You can therefore instruct your supplier to submit samples within the country.

Today, all major European and American compliance testing companies are present in the greater China region.

What should I look out for when selecting a compliance testing company in China?

You should only work with well known and established compliance testing companies, that are accredited in the United States and the European Union.

In fact, many countries only recognize test reports from accredited testing companies. You can find lists of accredited compliance testing companies on various government websites.

In addition, you can also use this checklist when selecting a testing company:

1. Do they offer compliance testing for the standards and regulations that your products must comply with?

2. Do they have experience with your product category?

3. Do they have a facility in Hong Kong S.A.R or Mainland China?

Should I book the test directly with the lab, or should the supplier manage this?

You should never let your supplier book the lab test for you. There are a few very good reasons for this:

a. They may select a non-accredited testing company. Thereby providing useless test reports. They may also forge test reports or bribe the testing company to produce a favorable result.

b. The supplier may not be aware of the regulations that apply in your market. Hence, they might order a test that is not corresponding to the regulations, safety standards or chemical restrictions in your target market.

c. You will end up paying for the test regardless. If you allow your supplier to book it for you, there is less transparency and you are exposed to the risks explained in a and b.

How do I submit product samples to the lab?

You can either deliver samples by mail to the lab testing company, or instruct your supplier to do so. Before you or the supplier submit samples to your testing company, you need to confirm the following information:

1. Contact person, phone number and address

2. Sample identification number / code

3. The number of samples required

That said, if you do let your supplier send the samples directly, be sure to get product photos or any other type of identification. There are stories of suppliers sending ‘made for compliance testing’ samples, only for the sake of passing lab testing – which don’t represent the batch as a whole.

Can a quality control agent handle testing while in the factory?

A common misconception is that quality inspections also involve product compliance checks. That is rarely the case, as compliance testing require expensive and bulky equipment, that is not exactly portable.

Further, it also requires expertise that is only possessed by chemical or electrical engineers.

That said, your quality inspection agent can collect samples from the batch, and later submit them to the testing company. That way you can be sure that the samples come from the ‘right box’.

How do I know what kind of tests I need to sell the product in my market?

Lab testing is done to prove compliance with one or more regulations or standards. Hence, you need to confirm which regulations and standards (i.e., REACH or CPSIA) apply to your product, in your market.

Most compliance testing companies can provide some basic guidance, but hire a consultant and contact the authorities in your target markets before you import products from Asia.

That being said, lab testing is not the only thing to take into consideration when it comes to product compliance. You may need to issue additional documentation, and most products are also covered by labeling requirements.

How many product samples should we send?

The testing company needs a certain number of samples per material, color, SKU and test. At a minimum, you will need to submit 3 to 4 sample units to get the product tested.

Confirm the number of samples required, with your testing company, and instruct your supplier accordingly.

Will we get our samples back after the test?

No, the samples are in many cases destroyed as a result of the compliance test. Hence, you cannot expect to get them returned.

There are exceptions though. Prototypes that undergo general checkups or a certification process (i.e., electrical systems that are EMC tested) must not necessarily be destroyed.

How long does it take to get the result?

It normally takes around 1 to 2 weeks, before the lab test is completed and the report can be issued. These days, test reports are mostly delivered digitally, rather than by post.

What can I do if the test fails?

In case the product fails to pass compliance testing, you need to work out the situation with the supplier. In some cases, the non-compliance can be resolved by replacing a certain component or material.

However, in some cases, it is impossible to ‘make’ a product compliant, especially when it comes to issues relating to chemicals and heavy metals.

In such cases, the supplier must remake the entire batch of products, as the entire batch is likely affected.

Do I need other documents than the test report?

Product compliance often involves much more than just lab testing. As mentioned, for some products, lab testing is mandatory – but for most it is not.

As such, it is up to the importer to decide whether or not to get the product tested.

Even in the cases when lab testing is not mandatory, additional product documentation may be so. In addition, most products are also subject to labeling requirements (i.e., Made in China label and CE mark).

For example, CPSIA requires US importers of children’s products to affix a tracking label to each unit, and issue a Children’s Products Certificate.

In the European Union, many products are subject to CE marking, which requires the buyer to draft a technical file – including design drawings, bill of materials, risk assessment, user instructions and much more.

      Fredrick that was a great article thanks. Wonder if you can help with a question of mine. My new company is planning on importing cosmetics from Alibaba into the UK for selling via FBA. Do you recommend any specific tests for cosmetics that will be used to reduce swelling using a cream with natural ingredients?

        Hi Mark,

        Cosmetics is unfortunately not our area of expertise. I suggest you contact Intertek or SGS.
