SummaryShijiazhuang Sincere Chemicals Co., Ltd. is a China-based limited trading company established in 2001 with 10 employees and no stated parent-group affiliation. Its business scope includes chemical and rubber product sales, technology and goods import/export, and certain regulated activities subject to approval. The supplier offers multiple listed chemical products and reports customization options ranging from sample- and design-based customization to full, minor, and flexible customization. However, it is explicitly not identified as a professional technical supplier, does not provide 3D software design services, has no SDK availability, and launched no new products in the past year. ISO9001:2015, ISO45001:2018, and ISO14001 certifications are listed, and regular fire drills were reportedly conducted. Financial records are indicated for 2022–2024, but no performance values are provided. No customer cases or explicit after-sales service evidence is available.

Supplier typeThe supplier is explicitly classified as a trading company and limited company, with 10 employees and no stated affiliation with a larger company group. Its activities center on chemical-product sales and import/export rather than disclosed manufacturing operations.

CertificationsThe supplier lists ISO9001:2015, ISO45001:2018, and ISO14001 certifications. These provide explicit evidence of certification holding, although the slices do not provide certificate numbers, issuing bodies, or validity dates.

R&D capabilityThe supplier is explicitly not a professional technical supplier, has no SDK availability, and launched no new products in the past year. These stated limitations indicate weak evidence of innovation capability.
