How to Verify That Your In-Stock Goods Share the Same Production Batch

When receiving goods from inventory, the most reliable first step is to check the batch number printed on each outer carton. Compare every carton, group those with identical references, and set aside any cartons with different markings until the supplier confirms their origin. This process is particularly useful for fly paper sheets and other adhesive pest-control products.

Batch Verification Steps

Before accepting a shipment, inspect the outer packaging and record the batch number shown on every carton. Matching numbers indicate that the cartons carry the same stated production-batch reference. Different numbers may mean that the shipment contains mixed stock, even when the product appearance is similar.

• Photograph or record the batch marking on every outer carton.
• Compare the carton references with the supplier's shipment information.
• Ask the supplier for written confirmation if any batch numbers differ.
• Keep photos or video showing the packaging, product condition, and affected quantity.

Why Batch Numbers Matter for Quality Claims

A batch number links the delivered goods to a specific production reference. If a quality concern is discovered after receipt, provide the supplier with the outer-box batch number together with clear photos or video. Yiwu Jinli Commodity Co., Ltd. states that production-quality issues involving adhesive products should be reported within 15 days after delivery.

After the supplier verifies the issue, the stated remedy may include free replacement of the affected quantity or a corresponding deduction from the payment. These arrangements are subject to the listed exclusions, including improper storage, extremely low temperatures, or local regulatory restrictions.

Inspection Information Relevant to Stock Checking

Yiwu Jinli describes a quality-control process covering raw-material inspection, production-process inspection, semi-finished product inspection, surface-treatment inspection, assembly inspection, final-product inspection, and packaging inspection. For buyers checking ready stock, the packaging stage and the batch marking on the outer carton offer the most direct traceability information.

The company also reports trade mark and copyright registrations, including trade mark certificate 15322289 and copyright certificate 黔作登字-2020-F-00118638. Its overseas cooperation records include sticky mouse board supply projects involving customers in India, Brazil, and Peru, demonstrating experience with international supply requirements without disclosing individual customer identities.

Frequently Asked Questions

How can I quickly determine whether inventory is from one production batch?

Read and compare the batch number printed on every outer carton. Identical references support the conclusion that the cartons are labeled as one batch, while different references should be treated as mixed stock until the supplier confirms otherwise.

Prepare high-resolution photos or video of the full carton, batch marking, product packaging, and product condition. State the quantity involved and include the shipment details so the supplier can trace the goods.

What is the procedure when a quality problem is found?

Send the supplier the relevant batch number and visual evidence within 15 days after receipt. Following confirmation, the stated support may be free replenishment or a payment deduction, subject to the applicable exclusions.
