AI-Powered supplier vetting

SummaryJiangSu XingRui Tools Co., Ltd. is a China-based limited company established in 2018, with 38 employees and five production lines. It offers thread taps and HSS drill bits, and its stated business scope includes manufacturing and sales of pneumatic and electric tools and metal-cutting processing services. The supplier reports ODM and OEM capabilities, but no available SDK and no new products in the past year. Service-management documentation is weak: no written procedures or records are reported for service assessment, corrective actions, or complaint handling. Overseas service coverage is listed as zero, although FOB, CIF, and EXW quotations and one-month lead times are available. Audit-related data identifies BV and an SGS report period, but the audit result is recorded as 0 without an explanatory interpretation. Financial information consists only of year labels, so financial credibility cannot be assessed.

After-Sales capabilityThe supplier reports no written procedures or records for service-capability assessment, corrective and preventive actions, or effective customer-complaint handling. It has no stated overseas service coverage, although it lists standard quotation terms and one-month peak- and off-season lead times.

R&D capabilityThe supplier reports no available SDK and no new products during the past year. It does report ODM service availability and OEM capability for popular brands, showing customization-oriented development support despite limited evidence of recent product innovation.

Production capacityThe supplier reports five production lines, 6–10 quality-control staff, one year of total R&D-engineer experience, and an annual production-output category. Its stated scope also includes manufacturing and sales of pneumatic and electric tools and metal-cutting processing services, supporting the existence of production operations, although engineering experience is limited.

Customization capabilityThe supplier explicitly reports ODM service availability and OEM capability for popular brands. Its product scope includes thread taps and HSS drill bits, while its broader business scope includes manufacturing and metal-cutting processing services, supporting a positive assessment of customization capability.

Product Q&A

Q:How do I choose this geometry?

Pipe thread form and taper or parallel designation must match the mating connection and gauge. Send the hole type, depth, material and machine setup so the correct variant can be selected.

Q:Are all material grades and coatings interchangeable?

No. Material, coating and cutting geometry are separate options. Confirm the exact combination and drawing for each ordered SKU.

Q:What size table governs my order?

The approved drawing and order confirmation govern pitch or TPI, overall and thread length, shank, square, chamfer and tolerance. The table above is a catalogue reference.

Q:Can you provide a batch material certificate?

State any chemistry, hardness or coating-document requirement before quotation so availability can be confirmed.

Q:Can I request mixed sizes or private-label packing?

Yes. Provide quantities by size, the required case or individual packaging, and your approved artwork and barcode rules.
