AI-Powered supplier vetting

SummaryHangzhou Dimacolor is identified as a China-based trading company and manufacturer/factory specializing in pigments, solvent dyes, and related colorants. The available evidence indicates ISO 9001 certification, five production lines, 6–10 R&D engineers, 6–10 quality-control staff, and stated annual production capacity of 10,000 metric tons. It has self-operated import and export rights, began exporting in 2012, and reports that 71%–90% of sales come from exports. However, the slices provide insufficient evidence to assess after-sales service, customization capability, or detailed customer performance. Financial information is limited to registered capital data, while only one trade transaction and one associated buyer are shown.

Supplier typeThe supplier is described as both a trading company and manufacturer/factory, while another record classifies it as a trading company. Its profiles identify it as a professional pigment manufacturer and exporter with products including organic pigments, solvent dyes, iron oxide, and related colorants.

CertificationsThe supplier explicitly reports ISO 9001 certification for its management systems. No other certifications are provided in the available slices.

R&D capabilityThe supplier reports 6–10 R&D engineers and offers a broad range of pigment and colorant products, including pigment dispersion, luminescent pigment, photochromic pigment, and concrete pigment. This supports the existence of R&D resources, but no information confirms patented technology, new-product development results, or measurable innovation outcomes.

Production capacityThe supplier reports five production lines, 6–10 quality-control staff, and annual production capacity of 10,000 metric tons. Its factory location is stated as Xiaoshan, Hangzhou, supporting a clear but self-reported production base.
