Cause of a defect

Establishing the probable cause of a shortcoming: manufacturing defect, transport damage, improper use, installation error, storage, natural wear or external impact.

What is included

Establishing the probable cause of a shortcoming: manufacturing defect, transport damage, improper use, installation error, storage, natural wear or external impact.

The examination uses the product, photographs, video, packaging, labeling, components, purchase documents, contract, technical specifications, specifications, product listing, formal claim, seller's response or service center's report.

What is checked

  • presence and nature of a shortcoming;
  • location and description of the defect;
  • probable cause;
  • traces of delivery, impact, dropping, opening, repair, use or installation;
  • completeness, packaging, tags, seals and labeling;
  • conformity to the contract, description, technical specifications, specifications and product listing;
  • whether an additional specialist in a relevant field or laboratory examination is needed.

What to provide

  • the product and packaging in their current condition;
  • photos and video of the defect;
  • receipt, order, contract and delivery note;
  • product description, listing, specifications or technical specifications;
  • instructions, warranty card and product data sheet;
  • correspondence, formal claim, seller's response or service report;
  • if supplied as a batch, batch documents and a selection of objects.

Pricing

from 30 000 ₽. The final fee depends on product type, number of objects, defect complexity, need for an on-site visit, document volume, number of questions and final document format.

How alternative explanations of a defect's origin are compared

One visible indicator may relate to manufacture, transport, assembly, storage or use. A substantive examination first describes the shortcoming itself: location, nature, size or functional manifestation. The suspected cause is recorded separately from the observation, so a party's initial explanation does not replace verification.

For each plausible explanation, identify supporting indicators and missing data. For example, the condition of a joint, damage locations, signs of previous intervention, installation documents or pre-handover photographs may matter. Considering alternatives helps explain why the chosen conclusion is more consistent with the materials.

Useful information to provide before inspection

  • When the shortcoming was first discovered and whether its manifestation changed.
  • Which operations took place between receipt of the product and discovery of the shortcoming.
  • Whether documents or images show its condition before those operations.
  • Which parts have been replaced, lost or are unavailable.

Not every sign of use is connected to the failure examined, and the absence of external damage does not automatically establish a manufacturing cause. A conclusion about the mechanism must be technically substantiated for the specific object.

If the available information establishes only the presence of a defect, that result must be distinguished from the question of its cause. A useful result shows the indicators found, explanations considered and limits of the answer. It clarifies whether an additional document, access to a component or a separate examination in a relevant field is needed.

Inquiry

A product has arrived, and you are unsure whether it is defective?

Send photos of the product, packaging, labeling and defect, purchase documents, contract, specifications, product listing, correspondence or the seller's report. We will initially determine which questions can be put forward for examination.

  • whether the product has a shortcoming;
  • whether it is a manufacturing defect, delivery damage, a result of use or an acceptable condition;
  • whether the product conforms to the description, contract, technical specifications and stated contents;
  • which format to choose: inspection record, specialist opinion or review.

How data is processed: Personal Data Processing Policy. Attach only the materials needed; where possible, conceal unnecessary data about other people.

Before inspection, preserve the product, packaging, labeling, tags, components, receipt, contract, correspondence and photos and video of receipt where possible.

Attachments: up to 10 files of up to 10 MB each, with a maximum combined size of 15 MB. If a file is rejected, the enquiry is not sent.

Product examination: whether it is defective, defect causes, delivery, completeness and description
