Frequently Asked Questions
Are all components 100% genuine and authorized?
Yes. Every component in our ready-stock inventory is sourced exclusively through authorized distribution channels directly from manufacturers or their appointed distributors. We maintain a strict zero-tolerance policy against grey market and counterfeit components.
What is the minimum order quantity (MOQ)?
Most components are available in single-unit quantities, making Keszoox ideal for prototyping and R&D. Bulk pricing tiers are available for production volumes — contact us for a volume quote.
Can I get date codes and lot traceability?
Yes. Date codes, lot numbers, and certificates of conformance (CoC) are available upon request for all orders. This is standard practice for our industrial and automotive customers.
Do you stock obsolete or end-of-life (EOL) components?
We maintain buffer stock of many components that have been discontinued or placed on allocation. If you need an EOL part, contact our team — we may have remaining stock or can suggest a pin-compatible alternate.
How quickly will my order ship?
In-stock orders placed before 3PM (local warehouse time) ship the same business day. Express delivery to most destinations in 2–5 business days via DHL or FedEx.
Do you provide ESD-safe packaging?
Yes. All ESD-sensitive components (ICs, MOSFETs, microcontrollers, RF modules) are shipped in anti-static bags, moisture barrier bags (MBB), or conductive trays as appropriate for the component type.
