We manufacture high-purity fused-silica cuvettes, flow cells and quartz plates in Yixing, China, and ship to US laboratories, universities and distributors every day. This page explains how a US order is processed, which carriers we use, typical transit, and what to expect at US customs.
Yes. We ship worldwide, and the United States is one of our busiest destinations. US customers order both in-stock items and custom-made cells — from a single 10 mm quartz cuvette for a routine assay to bulk and OEM quantities for production.
Our products are used with standard spectrophotometer holders from Agilent, Shimadzu, PerkinElmer, Thermo Scientific, Hitachi and Jasco, so a US lab can drop a Scuvette cell straight into existing instrumentation.
Lead time depends on whether the item is in stock or made to your specification:
| Item type | Production lead time |
|---|---|
| In-stock (standard cuvettes, quartz plates) | Dispatched within 1 business day after payment confirmation |
| Custom / made-to-spec (screw-cap to drawing, special path length, non-standard windows) | 10–20 business days to produce |
There is no minimum order quantity — US labs routinely order one cell or a few, and scale up to bulk runs when needed.
Our standard US service is Yanwen international express, which delivers to the United States in 8–15 days from our export hub. DHL, FedEx and UPS are available on request for faster delivery. For larger or heavier shipments, economy air or sea freight can be arranged on request.
For an in-stock order, the full journey to your US door is:
| Step | Time |
|---|---|
| Dispatch from our Yixing warehouse (after payment confirmed) | 1 business day |
| Transit to Shanghai export hub | ~2 days |
| Yanwen international express to the US | 8–15 days |
| Estimated total to US door (in-stock) | ~11–18 days after payment |
A tracking number is emailed to you as soon as the parcel is handed to the carrier.
Laboratory consumables and optical components imported into the United States may be reviewed by US Customs and Border Protection (CBP). Whether duties or taxes apply, and at what rate, is determined by CBP based on the product type and declared value.
Most US orders ship on Delivered At Place (DAP) terms — import duties and taxes, if any, are paid by the buyer at delivery. If you prefer a Delivered Duty Paid (DDP) quote with duties prepaid and included in one all-in price, contact [email protected] before ordering and we will quote it per shipment.
Once dispatched you receive a tracking number by email. Most carriers deliver to the door; a signature may be requested for higher-value parcels. If a delivery attempt is missed, the carrier will leave instructions for redelivery or pickup.
