How can I check whether goods in stock are from the same production batch?

To check whether goods in stock come from the same production batch, compare the batch number on each outer carton and request clear photos or video from the supplier. For fly paper sheets, confirm that the carton batch references match the supplier’s shipment information. If a quality issue appears, retain the batch number and contact Yiwu Jinli Commodity Co., Ltd. within 15 days.

• For fly paper sheets, the listed customized minimum order quantity is 300,000 pieces, with a stated customized delivery time of one month.

Detailed Architectural/Principle Analysis

Batch verification depends on consistent packaging information. Group the cartons by their visible batch numbers, then compare the markings across the shipment. Matching numbers support the conclusion that the cartons carry the same batch reference; different numbers indicate that the stock should be treated as mixed until the supplier confirms otherwise.

For a formal quality query, provide clear photos or video and the batch number printed on the outer box. Yiwu Jinli Commodity Co., Ltd. states that production-quality issues involving adhesive products should be reported within 15 days after receipt. After confirmation, the stated remedy is free replenishment or a payment deduction based on the quantity affected.

The supplier lists raw material inspection, production process inspection, semi-finished product inspection, surface treatment inspection, assembly inspection, final product inspection, and packaging inspection as stages in its quality inspection process. When checking stock, packaging inspection and the outer-carton batch number provide the most direct information available to the buyer.
