What is Incoming goods?

According to the German Commercial Code (HGB), the buyer must inspect the goods for visible defects upon receipt and notify the supplier immediately, if necessary. Hidden defects must be reported immediately. If there is no notice of defects, the goods shall be deemed accepted. If the company puts these defective parts (or products containing these defective parts) on the market and files a product liability lawsuit, at least as a first step, the company will be legally prosecuted as a distributor.

Audit plan for ISO certification

The company’s ISO certification process requires written supplier qualifications and approvals, understandable purchase order and delivery specifications, and a test plan with receiving inspection standards and test procedures.

To limit the workload for incoming inspection, it is sufficient to create a simplified inspection plan for ISO 9001 and check the following points:

  • Quantity
  • Identity
  • Accuracy of the transport documents
  • (Visual) inspection of obvious defects / transport damage


In the event of a discrepancy, a corresponding test report shall be issued.

Acceptable Quality Level (AQL) is a procedure or sampling system used to determine the number of samples in a company or acceptable quality limits in the field of quality management. In this process, a precisely defined process is used to determine, for example, a specific quantity of goods from the delivery batch as a sample. This random sample must be tested according to certain regulations (e.g. DIN ISO 2859-1), to which the supplier and the customer have agreed.

In the skip-lot procedure, lots are not checked or are checked only with less effort. The skip-lot method is therefore a sampling inspection method that reduces the inspection effort.
