Marine Crossion Service Limited supplies copper alloy bars manufactured in China. The bars are made from electrolytic copper with a minimum purity of 99.9 % and contain alloying elements designed for marine corrosion resistance. They are a key component of impressed current cathodic protection (ICCP) systems used on ship hulls, offshore platforms and subsea structures. The relevant HS Code is 7403.11, covering electrolytic copper in bar form.
Industry practice typically offers round or square bars from 10 mm to 50 mm in diameter and lengths of 1 m to 3 m, with a standard tensile strength around 210 MPa. Dimensional tolerance is usually ±0.2 mm for diameters under 30 mm and ±0.3 mm for larger sections. Shipments are commonly packed in wooden crates with protective coating and accompanied by a mill test certificate.
Primary buyers include shipyards, offshore platform owners and manufacturers of ICCP anodes who require bulk quantities. The supplier can arrange FOB or CIF terms, but exact lead‑time and MOQ must be confirmed directly with the company. Buyers should request a mill test certificate and verify alloy composition before loading. Payment is often handled via letter of credit, aligning with standard international trade practice.

Before placing an order, importers should ask Marine Crossion Service Limited for a recent mill test certificate that lists the exact chemical composition, copper purity and mechanical properties of the alloy bars. The supplier should also confirm the HS Code 7403.11 and provide dimensional drawings that show diameter, length and tolerance. Verifying these documents helps avoid customs delays and ensures the material meets the specifications required for ICCP systems.
The company indicates that FOB or CIF terms can be arranged, but the precise incoterm and estimated lead‑time are not disclosed publicly. Buyers should negotiate the preferred port of loading in China and request a shipping schedule that aligns with project timelines. Clarifying whether containerised or bulk loading will be used aids in calculating freight costs and planning downstream logistics.
For quality assurance, importers often engage a third‑party inspection agency to verify bar dimensions, surface condition and compliance with the supplied mill test certificate before loading. Upon shipment, the supplier should issue a certificate of origin, commercial invoice and packing list that match the declared specifications. Keeping these records facilitates smooth customs clearance and supports any future warranty or liability claims.
