## 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." (北京三角湾科技有限责任公司) 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. The published reference retail prices 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.
