About Ningbo Haitian Hardware & Plastic Co., Ltd - Bolts Supplier in China

Ningbo Haitian Hardware & Plastic Co., Ltd is based in Ningbo, Zhejiang province, China and lists five active product entries in its catalogue. The company’s catalogue covers standard fasteners such as Bolts, Screws and Washers together with a Brass fitting and a Hinge, each identified by its generic product name. The listed items fall under the broad hardware category and are typical of the small‑size mechanical components exported from Chinese manufacturers. No additional product lines or proprietary designs are mentioned in the supplied data. All entries are presented without specific material or dimensional details, reflecting a focus on generic fastener types rather than specialized engineered components.

The supplier’s catalogue groups the items by function: Bolts and Screws serve as threaded joining elements, Washers act as load‑distribution components, Brass fittings are usually for fluid connections, and Hinges provide pivoting motion. Each product is associated with a generic HS‑code family used for hardware, but the exact codes are not disclosed in the source facts. The count of five distinct product entries indicates a narrow but focused product scope, suitable for buyers seeking standard hardware components from a Chinese source.

Product Range and Specialties of Ningbo Haitian Hardware & Plastic Co., Ltd

The five catalogue entries include metric Bolts, standard carbon‑steel Screws, plain Washers, a Brass fitting and a metal Hinge. In the fastener market, Bolts are commonly supplied in grades 8.8, 10.9 or 12.9, with thread standards such as ISO 68‑1 (M‑series) or UNC/UNF for imperial sizes. Screws may be supplied as pan head, flat head or socket head, typically in stainless‑steel (A2, A4) or zinc‑plated carbon steel. Washers are offered as plain, lock or spring types, often with thicknesses ranging from 0.5 mm to 3 mm and diameters matching standard bolt threads. Brass fittings generally conform to BS 4290 or equivalent, used for pipe connections, while Hinges are usually stamped steel or stainless steel with pin diameters from 2 mm to 6 mm. These industry specifications provide a baseline for evaluating the supplier’s generic listings.

Trade and Export Information - Ningbo Haitian Hardware & Plastic Co., Ltd

China is one of the world’s largest exporters of fasteners, with the majority of shipments destined for the United States, the European Union, and Southeast Asian markets. Export shipments of bolts, screws and washers typically use 20‑foot or 40‑foot containers packed on wooden pallets, with each pallet holding 1 000 kg of mixed fasteners. Buyers often require compliance with ISO 9001 quality management systems and may request CE marking or RoHS declarations for metal components destined for the EU. Standard customs documentation includes a commercial invoice, packing list and, where applicable, a material safety data sheet (MSDS) for brass alloy fittings. Logistics for hardware from China frequently employ FOB Ningbo or CIF destination ports, reflecting the coastal facilities available in the region.

Sourcing from Ningbo Haitian Hardware & Plastic Co., Ltd - Buyer Guidance

When sourcing from Ningbo Haitian Hardware & Plastic Co., Ltd, buyers should request detailed product data sheets that specify material grade, thread size, tensile strength and surface finish for each fastener type. Third‑party test reports, such as tensile testing according to ISO 898‑1 for bolts or hardness testing for brass fittings, help verify compliance with typical industry standards. Samples of the actual parts, packaged in the same bulk cartons intended for shipment, enable physical inspection of dimensions and finish before confirming larger orders. Verification of the supplier’s ISO 9001 certification, or a statement that such certification can be provided, is advisable given the lack of explicit certification information in the source facts.
