About Jiangsu Aohai Anchor Chain Co., Ltd. - Industrial Chains, Anchor & Hooks Supplier in China

China hosts Jiangsu Aohai Anchor Chain Co., Ltd., which currently lists 11 active products across industrial chains, anchor hardware and related agricultural items. The catalogue includes 44mm Grade U2/U3 stud link chain cable, standard Grade U2/U3 stud links, a 68mm offshore chain supplied with a class certificate, and a marine casting centre shackle designed for anchor chains. Additional items are the AM3 38mm black tar stud link anchor chain, a navy‑type stockless anchor, a 64mm marine mooring anchor chain, and self‑coloured U1‑U3 stud link chains. The supplier also offers a high‑quality black marine anchor chain, a Danforth high‑holding‑power anchor, and an adjustable marine centre shackle, all described by size and basic grade without further certification details. The product list reflects typical marine‑grade steel chain components used in anchoring and mooring systems.

The listed items fall within the HS chapter 73 family for iron or steel articles, which is the standard customs classification for chain and anchoring hardware. Buyers of such products usually require compliance with international standards such as ISO 1361 for chain dimensions and EN 818 for tensile strength, as well as class society certificates (DNV‑GL, ABS, LR) for offshore applications. The absence of explicit HS codes in the supplier data prevents a direct citation, but the product types correspond to the usual 7315‑xx sub‑heading for chain and anchoring fittings. Export of these steel products from China typically follows bulk packaging in bundles or drums, loaded into 20‑ft or 40‑ft containers for shipment to shipyards and port facilities worldwide.

Product Range and Specialties of Jiangsu Aohai Anchor Chain Co., Ltd.

The catalogue focuses on marine‑grade steel chains and related hardware. Items such as the 44mm stud link chain cable, 68mm offshore chain with class certificate, and 64mm mooring anchor chain are offered in standard stud‑link configurations (U1, U2, U3) that meet the dimensional tolerances of ISO 1361. The black tar‑coated AM3 38mm chain and the adjustable centre shackle are designed for corrosion resistance in saltwater environments. Additional products include a navy‑type stockless anchor and a Danforth high‑holding‑power anchor, both common in commercial fishing and offshore platforms.

In the broader industry, stud‑link chains are classified by grade (U1‑U3) indicating tensile strength ranges from approximately 135 kN (U1) to 250 kN (U3) for 6 mm link pitch, with higher grades for larger diameters. Typical material specifications involve high‑tensile carbon steel, often heat‑treated to achieve a minimum yield strength of 355 MPa. Buyers frequently request compliance with class society standards (DNV‑GL, ABS) and may ask for test reports confirming proof load, elongation, and corrosion‑resistant coating thickness (e.g., tar or zinc).

Trade and Export Information - Jiangsu Aohai Anchor Chain Co., Ltd.

China is one of the world’s largest exporters of marine chain and anchoring systems, supplying shipyards, offshore oil & gas developers, and port authorities across Southeast Asia, the Middle East, Europe and the Americas. The primary HS headings for these goods are 7315‑xx (chain and chain fittings) and 7318‑xx (anchor fittings), which are subject to customs duties that vary by destination country but generally follow standard MFN rates for steel products. Export shipments are commonly packed in wooden crates or steel drums, with each 20‑ft container holding roughly 12‑15 tons of chain, depending on diameter and link type. Buyers typically arrange CIF or FOB terms, and may require an export class certificate that verifies compliance with the destination’s classification society requirements.

Regulatory expectations include proof‑load testing according to the class society’s guidelines, material test certificates (MTC) for steel grade, and corrosion‑coating certificates for tar‑ or zinc‑coated products. Many importing ports also conduct pre‑shipment inspections under the ISM Code or SOLAS regulations for safety‑critical anchoring equipment. The supplier’s listed class‑certified offshore chain aligns with these expectations, facilitating acceptance in regulated markets that demand documented test results and conformity to international standards.

Sourcing from Jiangsu Aohai Anchor Chain Co., Ltd. - Buyer Guidance

When sourcing chains or anchors from this supplier, buyers should request a material test certificate that specifies the steel grade, tensile strength, yield point and chemical composition. For offshore chains and class‑certified items, a class society approval document (e.g., DNV‑GL or ABS) should be obtained to verify that the product meets the required proof‑load and corrosion‑protection standards. Samples of the coating (tar, black paint) can be examined for thickness and adhesion, and buyers may ask for a third‑party inspection report that confirms compliance with ISO 1361 dimensions and EN 818 mechanical properties.

Verification of packaging details is also advisable; chains are normally bundled in steel straps or wooden pallets, and the total weight per container should be confirmed to match shipping line limits. Requesting a pre‑shipment inspection report (PSIR) can further ensure that the dimensions, link integrity and coating condition are consistent with the catalogue specifications before the goods leave the factory.

What sizes of stud‑link chain does Jiangsu Aohai provide?

The supplier lists 44 mm, 38 mm (tar‑coated), 64 mm and 68 mm stud‑link chains, covering grades U1‑U3 as indicated in the product titles.

Are the offshore chains class‑certified?

Yes, the 68 mm offshore chain is supplied with a class certificate, which typically aligns with standards from classification societies such as DNV‑GL or ABS.

Which standards apply to the marine chains offered?

Typical standards include ISO 1361 for chain dimensions, EN 818 for tensile strength, and class‑society rules (DNV‑GL, ABS) for offshore applications.

What documentation should a buyer request before purchase?

Buyers should ask for a material test certificate, the class certificate for offshore chains, and a coating verification report for tar‑coated items.

How are the chains packaged for export?

Chains are generally bundled in steel straps or placed on wooden pallets, then loaded into 20‑ft or 40‑ft containers; exact packaging details can be confirmed with the supplier.

Which markets typically import these marine chains?

Major importers include shipbuilding hubs in Southeast Asia, offshore oil‑and‑gas projects in the Middle East, and port facilities in Europe and the Americas.

What is the typical lead time for an order?

Lead times for steel chain products from Chinese manufacturers usually range from 30 to 60 days, depending on order size and any required certifications.

Can a buyer obtain sample chains for testing?

Yes, the supplier can provide small sample lengths for dimensional and coating verification; buyers should request a sample quote specifying the required size and grade.
