AI-Powered supplier vetting

SummaryQingdao Chengmingde Industry and Trade Co., Ltd. is a China-based trading company established in 2022 with two employees and a valid import/export license. It provides 3D software design and broad customization services, including sample-based, design-based, full, minor, and flexible customization, and also offers ODM services. However, it is explicitly not classified as a professional technical supplier, reported no new products in the past year, and has no SDK or known OEM service for popular brands. Finished products are checked by packing staff, while corrective and preventive action procedures or records are absent. The supplier has no overseas warehouse, showroom, overseas agent or branch, or offline trade-show participation. The provided financial records show zero reported operating revenue and other listed financial indicators for the stated periods, so financial credibility cannot be established from the available evidence.

Supplier typeThe supplier is identified as a limited trading company located in Qingdao, Shandong, China, rather than a professional technical supplier. Its stated business scope includes technical promotion, information-system operation and maintenance, appliance installation, fire-fighting and security equipment sales, and metal-product manufacturing through branches.

CertificationsThe supplier is explicitly reported to hold a valid import/export license. No other certification information is provided, so the assessment is limited to this license.

After-Sales capabilityQuality assurance is reported in quality-control processes, but there are no written corrective and preventive action procedures or records, and complaint-handling capability is recorded only as “Others.” The supplier also lacks overseas warehouses, showrooms, agents or branches, and has not participated in offline trade shows, limiting demonstrated service coverage.

Financial creditThe provided records report zero operating revenue and zero values for the listed costs, profits, cash receipts, cash inflows, cash outflows, and current ratio across the stated periods. These figures do not provide positive evidence of financial strength or operating activity, although no independent conclusion about solvency is possible from the slices alone.

R&D capabilityThe supplier provides 3D software design and ODM services, indicating some design-related capability. However, it is not identified as a professional technical supplier, reported no new products in the past year, and has no available SDK.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, flexible customization, and ODM services. It also provides 3D software design services, directly supporting a broad customization capability.

Product Q&A

Q:What materials are available?

Our vent caps use grade 304 (standard) or 316 (marine grade) stainless steel, both offering excellent rust and corrosion resistance. 316 is ideal for coastal or humid areas.

Q:What sizes do you offer?

We provide round and square models for 4 inch, 5 inch, 6 inch, 8 inch, 10 inch, and 12 inch ducts. Custom sizes available for bulk orders.

Q:Does it come with an insect screen?

Yes, all models feature a built-in fine mesh stainless steel screen (approx. 1mm opening) to keep insects, mice, and debris out while maintaining airflow.

Q:Can it prevent rain from entering?

Absolutely. Overlapping louvers shed rain and block wind-driven water. An optional backdraft damper offers extra protection against drafts and heavy storms.

Q:Is it suitable for dryer exhaust?

Yes, it's ideal for dryer vents. The 4 inch round model with a flap damper is popular. Stainless steel construction resists lint and high temperatures.
