Inventory disclosure
Supplier inventory changes. We confirm stock and ship timing again before quote.
What Marchiano verifies before quote
Marchiano uses SATA 81810 and the documented filter-series context as the starting evidence, then verifies the buyer's filter series, the identity of the offered cartridge, source, current stock or lead time, shipping, price, and applicable return or warranty terms. A prior dealer inventory observation is useful sourcing evidence, but it is re-checked because supplier inventory changes.
Best information to send
Send the filter series, quantity, urgency, and any visible label or old supplier reference tied to the existing cartridge. A clear photo of the filter assembly can help when the series is uncertain. Marchiano uses that evidence to confirm the correct sourcing route before quote and before any commercial commitment is made.
