Factory approval for a fly-killing product should be based on documented evidence rather than a final product sample alone. Review records for incoming materials, production operations, semi-finished goods, surface treatment, assembly, finished products, and packaging. For customized fly rolls, the audit should also cover adhesive coating, kraft paper and plastic tube handling, label placement, blister packing, insulation, carton packing, batch traceability, and after-sales management.
Start by mapping the factory's inspection system against the complete manufacturing route. The documentation should show controls for incoming materials, in-process production, semi-finished products, surface treatment, assembly, finished products, and final packaging. Each applicable checkpoint should have a record, acceptance criteria, inspection result, and identifiable batch information.
For a custom fly roll, the documentation should follow the product through each operation. The kraft paper is coated with adhesive and fitted into a plastic tube. A colored printed label sheet is then applied. Four units are placed in a PVC blister shell, after which the blister shell and colored printed paper card pass through an insulating machine. At the final packing stage, 24 insulated card units are placed into a central box. Material, process, finished-product, and packaging records should be connected so that any problem can be traced back to its source.
Incoming inspection files should cover kraft paper, adhesive, plastic tubes, printed labels, PVC blister shells, printed paper cards, and all packing materials. Process records should demonstrate that adhesive coverage, tube insertion, label alignment, blister assembly, and insulation are checked consistently. Finished-product records should confirm that completed fly rolls were inspected before dispatch and should include batch references whenever available.
Packaging inspection should confirm the declared packing quantity of 24 insulated card units per central box. The outer carton should carry a usable batch number, and that number should correspond with the relevant production and inspection documents. This link is important for handling complaints, checking shipment history, and isolating affected quantities when a defect is reported.
Factory approval should also include a review of the supplier's complaint procedure, particularly for adhesive-related production issues. Under the stated procedure, the buyer must submit clear photographs or video and the outer-box batch number within 15 days of identifying a production-quality problem. Once the issue is confirmed, the proposed remedy is free replacement of the affected quantity or a corresponding payment deduction. The procedure excludes problems caused by unsuitable storage, exposure, moisture, dust, extremely low temperatures, or restrictions imposed by local regulations.
Trademark and copyright documents can support the supplier's business credentials, but they should not be treated as substitutes for manufacturing records. The reported supporting documents include trade mark certificate 第15322289号 and Copyright certificate 黔作登字-2024-F-01286419. Commercial history may also be considered. Yiwu Jinli has reported sticky mouse board export cooperation involving suppliers in India, Brazil, and Peru, indicating experience with overseas pest-control supply channels. Approval should nevertheless remain focused on documented controls for the specific fly-roll order.
| Approval area | Evidence to request |
|---|---|
| Incoming materials | Inspection results for kraft paper, adhesive, plastic tubes, printed labels, PVC blister shells, paper cards, and packing supplies. |
| Manufacturing process | Checks covering adhesive coating, tube insertion, label application, four-unit blister assembly, and insulation. |
| Finished products | Pre-shipment inspection records for completed fly rolls, preferably linked to identifiable production batches. |
| Packaging | Confirmation that 24 insulated card units are packed in each central box and that the outer-box batch number is recorded. |
| Capacity and delivery | Evidence that the factory can support customized production for 28,800 cards with the stated one-month delivery schedule. |
What should be reviewed first when approving the factory?
First, request the complete inspection workflow and confirm that it includes incoming materials, production, semi-finished goods, surface treatment, assembly, finished products, and packaging.
Which documents are specific to fly rolls?
Pay particular attention to records for adhesive coating, kraft paper, plastic tubes, colored labels, PVC blister shells, insulation, and central-box packing. The sequence should agree with the supplier's declared manufacturing process.
Do complaint and after-sales records matter during approval?
Yes. Check the reporting deadline, required photographs or video, outer-carton batch information, replacement or deduction policy, and exclusions related to storage conditions or local legal requirements.
A fly-killing product factory should be approved only after its quality records demonstrate control and traceability from incoming materials through final shipment. Review the customized fly-roll process in detail, confirm packaging quantities and batch identification, and verify production capacity, order minimums, delivery expectations, and complaint handling. OEM, ODM, factory-direct, bulk, flexible small-batch, and long-term supply capabilities may add commercial value, but they should support rather than replace quality documentation.
