Scope & Limits — Read Before You Inquire
- Minimum order: no hard MOQ; for overseas orders we recommend at least 1,000 pcs per item because freight dominates small parcels.
- Lead time: 2–5 days for stock items; 15–25 days for production; 30–90 days for ODM/OEM projects.
- Custom work (dimensions, materials, colors, logo/barcode printing, molds, silanization, ultra-clean treatment) requires drawings or samples for quotation.
- What we do not do: we do not sell analytical instruments; we do not provide method development as a standalone service.
