AI-Powered supplier vetting
SummaryChangshu Hongyu Calcium Co., Ltd. is a China-based manufacturer of calcium oxide, calcium hydroxide, and environmentally friendly lime, established in 1984. The supplier reports ISO9001:2015 certification, multiple production lines, substantial stated annual output, export activity, and applications across petrochemical, lubricant, environmental, sewage-treatment, and related industries. It states that products can be organized according to customer requirements and that delivery can be ensured, but the evidence does not independently verify these claims. Information on after-sales service, financial credibility, and customer case details is limited. The provided records also contain inconsistencies in reported production-line count and quality-control staffing, so operational figures should be verified.
Supplier typeThe supplier is explicitly identified as a manufacturer and operates in chemicals, producing calcium oxide, calcium hydroxide, and environmentally friendly lime. Its legal and operating information places it in Changshu, Jiangsu, China.
CertificationsThe supplier reports holding an ISO9001:2015 management-system certificate. The slice does not provide the certificate number, validity period, or issuing body, but it is explicit evidence of certification.
Production capacityThe supplier reports a 4,000 m² manufacturing plant, three processing lines producing more than 100 tons of lime products per day in one description, five production lines in another record, and annual output of 100,000 tons each for calcium oxide and calcium hydroxide. These figures support substantial production capability, although the differing line counts should be verified.
Customization capabilityThe supplier explicitly states that it can organize required varieties according to users’ different product-quality requirements and deliver on time. This directly supports customization capability, although no examples, technical limits, or validation records are provided.
