AI-Powered supplier vetting
SummaryThe supplier is identified as a professional technical pigment supplier with manufacturing, quality-control, customization, ODM, and OEM capabilities. It reports in-stock capacity, self-operated import and export rights, and exports accounting for 51%–70% of total sales, but its exporting history is stated as two years. Customization options are broad, including sample-, design-, full-, minor-, and flexible customization. Quality assurance, raw-material traceability, RoHS certification, and regular fire drills are reported. However, the supplier does not provide 3D software design services or an SDK, reported no new products in the past year, lacks overseas warehouses, showrooms, agents, or branches, and has no factory environmental impact assessment report. Several service and complaint procedures exist without written records.
Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and describes pigment manufacturing supported by manufacturing techniques, quality control, research, and technological innovation. Its stated product focus is pigments, including environmentally friendly and safe product choices.
CertificationsRoHS is explicitly listed as the supplier's sustainable development and product certification. This provides evidence of at least one certification, although no broader certification portfolio is stated.
Production capacityManufacturing capability is supported by stated pigment production, manufacturing techniques, strict quality control, in-stock capacity, OEM service for well-known brands, and raw-material traceability. The supplier also has self-operated import and export rights and reports that 51%–70% of total sales are exports, although its export history is stated as two years.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. ODM services are also available, providing direct evidence of broad customization and design-manufacturing support.
Client casesThe supplier states that it provides OEM services for well-known brands, which is direct evidence of at least one customer-type case. However, no brand names, project details, volumes, or performance references are provided, so the breadth and verifiability of its customer cases cannot be assessed.
Product Q&A
Q:What is the difference between food grade and pharmaceutical grade Black Iron Oxide?
A:
Pharmaceutical grade has stricter heavy metal limits and microbiological controls, follows USP/NF or Ph.Eur. monographs, and is manufactured under CGMP with complete batch traceability and regulatory documentation. Food grade follows different standards (EU E172, FDA 21 CFR 73). Both are safe for their intended uses.
Q:Can this be used in wet granulation processes?
A:
Yes. Our Black Iron Oxide Pigment is stable under wet granulation conditions. We recommend pre-mixing with other dry excipients before adding the binder solution to ensure even color distribution.
Q:Does this pigment affect tablet hardness or dissolution?
A:
At recommended usage levels (0.5% ~ 2% w/w), this pigment has negligible impact on tablet hardness and dissolution profiles. We recommend process validation for new formulations.
Q:What documentation is provided with each batch?
A:
Each batch is accompanied by a Certificate of Analysis (CoA) that includes heavy metal testing results, a Certificate of Origin (CoO), and a CGMP compliance statement. Additional documents are available upon request.
Q:What are the available packaging options?
A:
Packaging options include 25kg net triple-layer kraft paper bags with PE liner, or 50kg HDPE drums.
