When membranes, cartridges or resins arrive, check the order, packaging and supply documents together before the relevant personnel arrange their use as required. Similar appearance does not establish identical models or applications.
Information preparation and assessment basis
First check that the brand, complete model, specifications and quantity match the order. Record batch, manufacturing and storage information as marked on the product. Record packaging damage, leaks or document discrepancies separately and contact the supplier first.
To verify the source, ask the supplier for purchasing, supply or authorization documents traceable to this batch. A certificate, brand logo or packaging photograph alone cannot establish that all goods came through the same channel.
Substitute models must match documents confirmed by both parties, and equipment and operating conditions must still be checked before use. Clearly mark unconfirmed products to keep them separate from stock already checked as usable.
Store, install and use materials according to the relevant product instructions and technical confirmation. Do not judge authenticity solely from impressions after opening the packaging, or publish transaction information without authorization.
For questions about models or documents, describe the intended use and discrepancies through an inquiry channel currently available on this page. Redact unrelated customer and personal information before sending photographs.
