AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company, but the provided information also indicates professional technical, R&D, design, OEM, ODM, inventory, overseas warehouse, overseas showroom, and export capabilities. It reports substantial annual production capacities across several fastening-product categories and offers extensive customization. Service governance is supported by written procedures and records for corrective actions, complaint handling, supplier assessment, and approved-supplier updates. Innovation evidence includes new products within the past year, while ERP-based digital management is in use. Financial records are referenced for 2021–2023, but no financial results or assessment outcomes are provided. No certification information is stated. Customer-related evidence includes OEM service for well-known brands, overseas agents or branches, and participation in named trade shows.

After-Sales capabilityThe supplier has documented and followed procedures for customer complaints and corrective/preventive actions. It also reports overseas agents or branches, overseas warehouses, an overseas showroom, inventory capability, and written supplier-service assessment procedures, supporting service coverage, although no specific warranty or repair terms are provided.

R&D capabilityThe supplier reports R&D capability, new products within the past year, ODM services, and ERP-based digital management covering production, procurement, quality control, and logistics. It has no available SDK, but that limitation is not sufficient to negate the broader product-development and process-digitization evidence.

Production capacityReported annual capacity includes threaded rods, bolts and nuts, anchor bolts, screws, and hex bolts, with the largest stated capacity for hex bolts. The supplier also reports in-stock capability, while outsourcing procedures and manufacturing-capacity contracts remain unknown; overall, direct production strength is supported but its full manufacturing governance is not established.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full, minor, and flexible customization, together with 3D software design services. ODM and OEM capabilities further support its ability to develop or manufacture customer-specific products.

Product Q&A

Q:What is your Minimum Order Quantity (MOQ)?

For standard in-stock items, we support small trial orders with no strict MOQ. For mass production or custom orders, the MOQ generally ranges from 100 kg to 500 kg per specification, depending on the product size and processing requirements. Please contact our sales team for specific details.

Q:How long is your delivery time?

For in-stock items, the delivery time is 7 to 10 days. For mass production or custom orders, it generally takes 30 to 45 days, depending on the order volume and specific production requirements.

Q:What is your payment method?

Our standard payment term is 30% T/T deposit in advance, with the remaining 70% balance paid against the B/L copy. For orders under $1,000 USD, we recommend 100% advance payment via T/T to minimize international bank charges. We also accept L/C at sight for large orders.

Yes, we provide standard samples free of charge, but the courier/freight cost is covered by the customer. For custom-made samples based on your drawings, a sample tooling fee may apply, which is refundable upon bulk order placement.

We work with a wide range of materials, including Carbon Steel, Alloy Steel, Stainless Steel (SUS304/SUS316), and Brass. For strength grades, we specialize in high-tensile fasteners, offering Grade 4.8, 8.8, 10.9, and 12.9 to meet rigorous industrial and engineering standards.
