REACH is a regulation of the European Union, which currently involves the testing of SVHC and the issuance of compliance assessment CHB reports. The market is currently mixed, and only institutions with the only representative qualification can effectively complete the entire REACH service, not just testing. The CNAS certificate issued by the National Laboratory Accreditation Service is an important basis for measuring a company's REACH capability. The CNAS certificate proves that a laboratory is managed in accordance with ISO17025, and this accreditation is currently recognized by 58 countries around the world.

The Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation was officially implemented on June 1, 2007. The purpose of regulations is to protect human health and the environment, reduce vertebrate testing, and be consistent with the international obligations of the European Union under the WTO framework.

On October 28, 2008, the ECHA High Concern Substance Candidate List containing 15 categories of substances officially came into effect, and companies must assume corresponding obligations for substances included in the authorized candidate list. Enterprises need to report their products to these high concern substances, provide sufficient information, and create safety data sheets. Recently, multiple shipments of goods to the European Union have been hindered by the EU REACH regulations, involving multiple countries including the United States, China, and Japan. The significant impact of REACH regulations on international trade has begun to emerge, posing more severe challenges to Chinese enterprises in their trade with Europe in the current global economic crisis. According to experts' estimates, due to the introduction of REACH regulations, all 140 billion euros in trade between China and the European Union will be affected, and industries such as home appliances, textiles, clothing, footwear, toys, light industry, electronics, automobiles, pharmaceuticals, etc. will be affected and harmed.
