About Donguang Ctube Industrial Co., Ltd. - PVC Fittings Supplier in China

China hosts Donguang Ctube Industrial Co., Ltd., which currently lists six active products in its online catalogue. All six items belong to the PVC conduit and fitting segment, covering tee connectors, elbow bends, junction boxes and three‑way fittings, each assigned to HS code families 3917 and 8538 as recorded in the source data. The catalogue specifies Polyvinyl Chloride (PVC) as the sole material, with dimensions ranging from 16 mm to 86 mm and standard angles such as 90 degrees. The supplier’s top‑level category is recorded as “Flanges”, but the detailed entries focus on PVC electrical conduit components. Geographic references are limited to the supplier’s origin, China, with no additional city or region disclosed.

Product Range and Specialties of Donguang Ctube Industrial Co., Ltd.

The six catalogue entries comprise three variants of 3917‑type PVC conduit fittings (25 mm tee, 20 mm tee, three‑way) and two 3917‑type elbow products (16 mm 90° elbow and a generic 16 mm 90° pipe). A single 8538‑type item is a 86 × 86 × 38 mm PVC cable junction box. In the broader PVC conduit market, manufacturers typically offer PVC‑U (unplasticized) grades meeting IEC 61386 or GB 50057 standards, with pressure ratings from 0.2 MPa to 1.0 MPa and flame‑retardant classifications such as UL 94 V‑0. Buyers often request dimensional tolerances of ±0.2 mm and surface finish grades (smooth vs. ribbed) for ease of installation.

Trade and Export Information - Donguang Ctube Industrial Co., Ltd.

China is a major exporter of PVC conduit systems, and products classified under HS 3917 (plastic tubes, pipes and fittings) and HS 8538 (electrical junction boxes) are regularly shipped to construction and infrastructure projects in Southeast Asia, the Middle East, Eastern Europe and Africa. Importers typically require compliance with CE marking, RoHS restriction statements and an ISO 9001 quality management system, although specific certifications must be confirmed with the supplier. Standard export packaging includes bulk cardboard cartons placed on wooden pallets, with container loading optimized for 20‑ft or 40‑ft units; Incoterms such as FOB Shanghai or CIF destination are common. Chinese exporters of PVC fittings often provide material safety data sheets (MSDS) and test reports for fire resistance, UV stability and dimensional accuracy to satisfy customs and buyer audits.

Sourcing from Donguang Ctube Industrial Co., Ltd. - Buyer Guidance

When sourcing PVC conduit fittings from Donguang Ctube, buyers should request the product data sheet that lists the PVC grade, wall thickness, pressure rating and compliance with IEC 61386 or GB 50057.

Verify that the supplier can supply test certificates for flame retardancy (e.g., UL 94), a recent ISO 9001 audit report, and an MSDS; absence of these documents should be clarified prior to contract signing. Typical minimum order quantities for Chinese PVC fittings range from 500 to 1 000 pieces per item, with lead times of 15 - 30 days after order confirmation.
