SummaryQingdao Julian Plastic Co., Ltd. is identified as a professional technical manufacturer of pipeline joint rehabilitation products and related sewage-pipe products. It has professional R&D personnel, three production lines, stated in-stock capability, customization from samples and designs, and an ISO 9001:2015 certificate. However, it does not provide 3D software design services, reported no new products in the past year, lacks written corrective-action and outsourcing procedures, and finished products are checked by packing staff. The supplier has no valid manufacturing contract with associated subcontractors, no overseas warehouse or showroom, and limited documented export-trade experience. The evidence supports strengths in supplier specialization, certification, customization, and basic production resources, while after-sales capability and customer-case evidence remain insufficient.

Its listed products include sewage pipes, electrofusion belts, heat-shrinkable sleeves, and clamps, indicating a focused manufacturing role in plastic pipeline and rehabilitation solutions.

CertificationsThe supplier holds an ISO 9001:2015 management-system certificate. This is explicit evidence of certification relevant to quality-management practices.

Production capacityThe supplier has multiple production-related machines, advanced sheet and heat-shrinkable-tape production lines, three production lines, in-stock capability, and stated lead times within 15 workdays in both peak and off-peak periods. Countervailing controls include no continuous batch quantity reconciliation and no written outsourcing SOP; additionally, no valid manufacturing contract exists with associated subcontractors.

Customization capabilityThe supplier explicitly offers customization from samples and designs. Its company description also states that it provides customized processing according to customer requirements, supported by product development and production personnel.
