How to Verify Whether Your Stock Shares the Same Production Batch

When goods arrive from existing stock, carton markings are the quickest way to check whether they carry the same production batch reference. Review each outer carton, document any differences, and ask the supplier to compare the markings with the shipment information. For fly paper sheets, these steps help clarify whether the delivered cartons are recorded under one batch or should be treated as mixed stock.

Steps for Checking Batch Information

1. Read and record the batch number printed on every outer carton before accepting the shipment.
2. Sort cartons by batch reference. Matching numbers show the same stated reference; different numbers mean you should seek supplier confirmation.
3. Take clear photos or video of the carton labels, packaging, and product condition for your records.
4. Compare the visible markings with the supplier’s shipment details and request written clarification if anything does not match.

For fly paper sheets, confirm that the batch references on the cartons correspond with the supplier’s shipment information. If the markings are unclear or inconsistent, share the evidence with the supplier before treating the stock as a single batch.

What to Include in a Quality Report

If you discover a quality concern after delivery, keep the affected cartons and note their batch numbers. Send Yiwu Jinli Commodity Co., Ltd. clear photos or video showing the outer-box markings, packaging, product condition, and affected quantity. The company asks customers to report adhesive-product quality issues within 15 days of receipt.

After the issue is reviewed and confirmed, the stated resolution is free replacement stock or a deduction from payment based on the affected quantity. The after-sales terms exclude issues resulting from improper storage, extremely low temperatures, or local regulatory restrictions.

Quality Checks and Supplier Information

The supplier describes a quality process that includes raw-material checks, production-process and semi-finished-product inspections, surface-treatment and assembly checks, final-product review, and packaging inspection. For buyers checking warehouse stock, the carton batch marking and packaging inspection are the most immediately visible sources of information.

Yiwu Jinli also reports holding trademark registrations and copyright certificates, including trademark certificate No. 15322289 and copyright certificate No. 黔作登字-2020-F-00118638. Its cooperation history includes sticky mouse board supply cases in India, Brazil, and Peru.
