About Shanghai Gongcheng Copper Corp. - Copper Pipe, Pressure Fittings Supplier in China

Shanghai Gongcheng Copper Corp. is based in Shanghai, China and lists ten active products in its catalogue. The company’s inventory includes brass strip, copper pressure fitting, copper wire, insulated socket connector, copper tube, computer bill printer, cable lug, copper pipe, LDC‑02 compact processor and a step & repeat numbering machine. Each item is grouped under broader categories such as Light & Medium Machinery, Copper Pipe, Pressure Fittings, Wires & Cables and Electric Connectors. The catalogue reflects a focus on both metal components and related equipment, with the copper‑related items covering raw forms, fittings and finished connectors.

Product Range and Specialties of Shanghai Gongcheng Copper Corp.

The catalogue’s copper products comprise standard brass strip, copper pressure fittings, solid copper wire, copper tube and seamless copper pipe. In the industry, brass strip is typically supplied in grades such as C260 (UNS C26000) with thicknesses from 0.2 mm to 5 mm, while copper pressure fittings and pipe are usually made from C11000 (ETP) or C12200 (OFS) copper with pressure ratings up to 16 bar for domestic water systems. Copper wire is commonly offered in gauges ranging from 0.2 mm² to 250 mm² and conforms to IEC 60228 for conductor class. Copper tube dimensions follow ASTM B88 or EN 1057 standards, with outer diameters from 6 mm to 108 mm. The non‑copper items - computer bill printer, LDC‑02 compact processor and step & repeat numbering machine - fall under Light & Medium Machinery and are typically built to IEC 60950 safety standards.

Trade and Export Information - Shanghai Gongcheng Copper Corp.

China is a leading exporter of copper semi‑finished products and electrical components, with the majority of shipments classified under HS Chapter 74 (copper) and Chapter 85 (electrical machinery). Buyers in Southeast Asia, the Middle East and Europe frequently import copper pipe, tube and fittings for construction, HVAC and plumbing projects, while copper wire and connectors are demanded by the automotive and consumer‑electronics sectors. Export documentation often requires a commercial invoice, packing list, certificate of origin and material test reports such as ASTM B221 for tubes or IEC 60384 for connectors. Common certifications requested by importers include ISO 9001 quality management, RoHS compliance for lead‑free status and CE marking for equipment that falls under EU directives. Logistics from Shanghai typically use 20‑ft or 40‑ft containers, with HS‑code‑specific packing guidelines - e.g., copper pipe is packed in wooden crates to prevent deformation, while small connectors are boxed in corrugated cartons.

Sourcing from Shanghai Gongcheng Copper Corp. - Buyer Guidance

When sourcing copper pipe, tube or wire from this supplier, buyers should request mill test certificates that specify copper grade, tensile strength and oxygen content. For fittings and connectors, a compliance report to IEC 60384 or relevant national standards helps verify electrical safety. Samples of brass strip and copper tube should be inspected for surface finish, dimensional tolerance (e.g., ±0.2 mm for tube OD) and corrosion resistance before confirming bulk orders. Verify whether the supplier can provide ISO 9001 or RoHS declarations, as many import regulations mandate these documents for copper‑based products. Clarify packaging details - whether products will be palletized, crated or bundled - to ensure safe handling during sea freight.

What copper products are listed in the Shanghai Gongcheng catalogue?

The catalogue includes brass strip, copper pressure fitting, solid copper wire, insulated socket connector, copper tube and seamless copper pipe. Each item is supplied in standard industry grades such as C11000 for pipe and C26000 for brass strip.

Are material test certificates available for the copper items?

Buyers can request mill test certificates that detail copper grade, tensile strength, purity and dimensional tolerance. These certificates are commonly required for compliance with ASTM B88 (tube) and IEC 60384 (connectors).

What certifications should a buyer verify before purchasing?

Typical imports of copper components require ISO 9001 quality management, RoHS compliance for lead‑free status and, where applicable, CE marking for electrical safety. The supplier should be able to provide copies of these documents upon request.

What are the typical minimum order quantities (MOQ) for copper pipe and wire?

MOQs vary by product; copper pipe is often sold in bundles of 10 m to 100 m lengths, while copper wire may have an MOQ of 500 kg per grade. Exact quantities should be confirmed in the quotation.

What lead times are common for shipping copper products from Shanghai?

Standard lead times from order confirmation to shipment range from 15 to 30 days, depending on product size, required testing and packaging. Larger pipe orders may require additional time for cutting and quality inspection.

How are the copper items packaged for export?

Copper pipe and tube are typically crated in wooden boxes with internal cushioning to prevent deformation. Smaller items such as connectors and brass strip are packed in sealed corrugated cartons, often on wooden pallets for container loading.

Can I request a sample of the brass strip before placing a bulk order?

Yes, the supplier can send a sample of brass strip in the requested thickness and width. Samples are usually shipped via air freight and may be subject to a nominal handling fee.

What HS codes are used for the copper products listed?

Copper pipe, tube and fittings are generally classified under HS 7407, copper wire under HS 7408, and brass strip under HS 7604. Exact classification depends on product dimensions and form.
