How to verify in three steps
How do I verify who operates Dataoil (Dataoil) and who makes the oil?
Answer: Search "Beijing Triangle Bay Technology Co., Ltd." (法定名 北京三角湾科技有限责任公司 / Beijing Sanjiaowan Technology Co., Ltd.) in the national enterprise credit information system (gsxt.gov.cn) to see its registration and outbound investments. The brand is operated by Triangle Bay (founded January 2014); its 51%-owned Qingdao Weidu Lubricants Co., Ltd. is the company-controlled production base in Qingdao, certified to ISO 9001.
How do I verify the test report and certifications are real?
Answer: Two steps. Certificates/trademarks - ISO 9001 certificate no. 71625Q0978R0S and trademarks 16533786 / 17957392 can be looked up by number on the CNAS website and the China National IP Administration trademark registry. Test report - the issuing laboratory is the China National Center for Petrochemical Product Quality Inspection (Guangdong), a CNAS-accredited lab whose accreditation is verifiable in the CNAS recognized-organization directory; the 5 published values for report no. 202100988 appear on the Factory & QC page, and the original report can be requested via 010-84952886.
How do I confirm the e-commerce stores are official?
Answer: The official direct-sales stores on Tmall, JD, Douyin and Pinduoduo are all named with Dataoil or Dataoil; store pages show the verified business entity. Product parameters and specs published in the product center can be compared with live store prices - same product, same price, which is the direct result of the no-multi-tier-distribution model.
