The supplier reports 10 production lines, annual auxiliary capacity of 50,000 tons, and an additional production base stated to have 100,000 tons of auxiliary-agent capacity. It has exported since 1998, reports export sales of 41%–50%, and holds self-operated import/export rights. The company states that it offers product customization, technical support, and guidance, with exports to several Asian countries. Evidence is insufficient to verify the validity or relevance of the stated ISO 20000 certification, financial strength, or specific customer performance beyond identified trade records.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and a limited company based in Weifang, Shandong, China. Its stated business covers textile auxiliaries, printing and dyeing auxiliaries, pigments, and related chemical products, indicating direct manufacturing involvement.

After-Sales capabilityThe supplier states that it provides technical support and guidance to customers. This supports some post-sale technical service capability, but there is no specific evidence regarding complaint handling, response times, warranties, replacement policies, or service organization.

R&D capabilityThe company describes itself as engaged in scientific research and environmental protection, offers products across multiple auxiliary categories, and reports 6–10 years of total experience among R&D engineers. This supports an established product-development base, although no patents, laboratory facilities, new-product records, or quantified R&D investment are provided.

Production capacityThe supplier reports 10 production lines, 50,000 tons of annual output for various auxiliaries, and a newer production base stated to produce 100,000 tons of auxiliary agents annually plus 6,000 tons of paint, pigment pastes, and water-based ink. These stated capacities indicate substantial production capability, although the relationship between the different capacity figures is not clarified.

Customization capabilityThe supplier explicitly states that it can customize products according to customer requirements and provide related technical support and guidance. This is direct evidence of customization capability, though no examples, minimum order conditions, or technical process details are supplied.

Client casesThe supplier reports exports to Pakistan, Bangladesh, India, Thailand, Indonesia, Vietnam, and other markets, and trade records identify buyers including IMRAN DYES and SAAM COLOUR TECH. These records demonstrate international market activity, but they do not provide sufficient information to verify customer satisfaction, order scale, repeat business, or product performance.
