Yajiada — Verified Supplier
About Yajiada - Nails Supplier in China
Yajiada operates out of China and currently lists seven distinct hardware items in its catalogue. The product set covers four core categories: nails, screws, wires & cables, and steel wires. Within the nail segment the supplier offers high‑quality common nails, low‑price coil nails, concrete nails sold directly from the factory, roofing nails for umbrella roofs, and a versatile nail wire product. The screw offering is a drywall screw marketed with a favorable price. The only item with a specified customs classification is a low‑price cut wire assigned HS code 7217.20 and described as high‑carbon steel, galvanized.
The catalogue does not provide detailed dimensions, but the listed items correspond to standard construction fasteners widely used in building projects. The cut‑wire product falls under HS Chapter 72 for steel wire products, which typically requires compliance with tensile‑strength specifications measured in MPa. Yajiada’s product list reflects the common assortment found in Chinese fastener manufacturers that serve both domestic construction and export markets. The supplier is classified in the “harbor” trust tier, indicating a level of verification within the platform. No additional product specifications, such as coating thickness or length, are supplied in the facts.
Product Range and Specialties of Yajiada
The catalogue enumerates seven fastener items: high‑quality common nails, low‑price coil nails, factory‑direct concrete nails, drywall screws, roofing nails for umbrella roofs, a versatile nail wire, and a low‑price cut wire (HS 7217.20). In the nail market, common nails are usually supplied in diameters ranging from 2 mm to 6 mm and lengths from 25 mm to 120 mm, often meeting ASTM A153 for zinc coating. Coil nails are typically produced in high‑speed coil‑forming machines and are graded by wire gauge (e.g., 0.9 mm to 1.2 mm) and holding power. Concrete nails are hardened steel, frequently conforming to DIN 1052, and may carry a galvanized or epoxy coating for corrosion resistance.
Drywall screws are generally #6 to #8 gauge with a coarse thread, designed to meet ASTM C1002 for gypsum board fastening. Roofing nails for metal or umbrella roofs are commonly produced from high‑carbon steel with a flat or ring head, often required to meet ISO 9001 quality‑management standards. The versatile nail wire and the cut wire listed under HS 7217.20 are steel wire products; standard specifications include tensile strength of 400 - 600 MPa and a minimum zinc coating of 5 µm for corrosion protection. Buyers typically request material test reports, dimensional drawings, and coating thickness certificates for these categories.
Trade and Export Information - Yajiada
Chinese manufacturers of nails, screws and steel wire products primarily export to construction‑intensive regions such as Southeast Asia, the Middle East, Europe and North America. The cut‑wire item cited with HS 7217.20 belongs to the steel wire products chapter, which is subject to customs duties based on weight and may require a Certificate of Origin for preferential trade agreements. Fasteners like nails and screws fall under HS 7318 and HS 7317 respectively, and importers often request compliance with ASTM A153 (zinc coating) or EN 14679 (corrosion‑resistant steel).
Typical import documentation includes a commercial invoice, packing list, bill of lading, and, where required, a material safety data sheet for coated steel products. Buyers frequently ask for ISO 9001 certification, CE marking for EU markets, and test reports confirming tensile strength, hardness and coating thickness. Shipping is usually performed in 20‑ft or 40‑ft containers, with nails packed in bulk bags or cardboard cartons and wire products coiled and strapped on pallets. Common Incoterms used by Chinese fastener exporters are FOB Shanghai or CIF destination port, depending on buyer preference.
Sourcing from Yajiada - Buyer Guidance
When sourcing Yajiada’s fasteners, buyers should request detailed product datasheets that list dimensions (diameter, length), material grade (e.g., high‑carbon steel, galvanized), and any applicable standards such as ASTM A153 or DIN 1052. For the cut‑wire (HS 7217.20), a tensile‑strength test report and a galvanization thickness measurement are standard verification items. Samples are typically supplied in small bulk quantities packed in cardboard boxes to allow physical inspection of coating quality and dimensional accuracy.
Before confirming an order, verify that the supplier can provide a Certificate of Origin and, if required by the destination market, an ISO 9001 quality‑management certificate or CE conformity declaration. Check the packaging details - nails are often bundled in 1 kg or 5 kg packs, while wire products are shipped in coils secured on pallets - to ensure they meet handling and storage requirements. Clarify the minimum order quantity, lead time (commonly 15 - 30 days for standard fasteners from Chinese factories), and the preferred Incoterm to align logistics with your supply chain.
