Import from China Tutorial 11: Laboratory Testing for Your Products


Table of Contents


Laboratory testing is not mandatory and it depends on the compliance regulation of the target market. However, this is the only way to figure out whether the product meets all relevant standards or not.You may submit samples for testing before or after production, or both. However, many regulations require that samples should be collected from the batch of mass-produced products.


Tips For Lab Testing

Normally, if you want to test your product for compliance, the cost will be borne by the buyer, but you can ask your supplier to cooperate with your arrangements. The following tips may be useful.

Find An Accredited Third-party Testing Company

You’d better choose a third-party testing company on your own rather than having your supplier to do it for you. So that you can ensure that

  • You will receive a testing report issued with your company’s name, otherwise it will be useless for you.
  • Your supplier will not interfere with the test results.

Of course, you’d better conduct a background verification on the targeted testing company before booking a test to make sure that the company is qualified to issue testing reports and the reports are accredited.

Create A Check Plan First

Before booking a laboratory test, you’d better figure out the following questions. Checklist

  • Is lab testing mandatory for your product in your target market?
  • According to which regulations or standards that the product should be tested?
  • Test all products (such as different colors for the same products) or just a few?
  • Which product or materials should be submitted for testing?
  • Should product packaging be tested?
  • Can you identify risks that reflect foreseeable usage?

Book Ahead

Book At Least 2 Weeks Before Production Completed

You should contact the testing company at least 2 weeks before since they need to make preparation for the incoming batch samples. And at the same time, you can get the following information from your testing company.

Confirm the Following Information

  • Required sample material quantity: according to different testing requirements, they may need more than one unit)
  • Delivery address and contacting people
  • Sample ID number: sometimes it can be booking number, but this number must be fixed to affixed to the incoming sample
  • Applicable regulations: you can ask the testing company to assess which standards will be applicable for your products in your target market. But they can’t ensure that the assessment they give is completely correct, and they don’t take responsibility for unstuitable assessments. So you can’t just rely on the testing company’s advice, you’re better off doing your own research on the compliance rules of your target market of a certain product.
  • Estimated cost: this is just a rough quotation, the final quotation will be given to you when they receive the samples.

Sample Submission

  • You may also submit pre-production samples for testing. But actually a batch sample is a more accurate representation of the product that you want to sell on the target market.
  • Try not to let suppliers send samples since the suppliers may submit a compliant sample for self-interest. A compliant sample is a sample especially made to pass the test, but in fact, the products are not compliant. In order to avoid this risk, you can ask the quality inspector to collect the batch samples and submit them to the testing company.
  • Ensure the sample ID is affixed to the envelop correctly. Otherwise, the testing company may have difficulty in identifying the samples.
  • After the testing company receive your samples, they will give you a final quotation. And if you accpet this price, they will ask you to make a payment before they perform testing.

Test Report

  • Ensure that the test report is issued with your company’s name
  • You can receive the report within 1-2 weeks by email
  • It is a proof of compliance and can be submitted to authorities and customers.

Sometimes, the test report is not the only needed document. Accourding to the compliance regulations, you may also need some additional documents, such as technicial documentation, declaration of confirmity and so on.

What If the Test Fails?

If the submitted sample does not pass the test, then you can take the following steps.

  • Figure out the reasons for failure and ask your supplier to repair or reproduct the products.
  • After repairment, please conduact another round of test and ask your supplier to pay for the follow-up test.
  • Don’t pay the balance until the test passed.
  • Ask for a refund if necessary.
