China XianJing Oil Filtration Group

China XianJing Oil Filtration Group has been in business since 1999, showing long-term presence and experience in the oil filtration market. Their product range includes machine oil purifiers, oil filters, and oil residue — all key components in industrial maintenance and lubrication systems. Being based in China gives them access to large-scale manufacturing and cost-efficient production. However, none of their key verification details — work email, phone, account email, or business documents — are confirmed, which raises concerns about legitimacy and reliability. Buyers should request additional proof before placing large orders or committing to long-term supply. Without verified contact or documentation, it's hard to verify their real operations or track orders. This lack of verification is common among older Chinese suppliers, but it still increases risk for new buyers.
