Shipping Policy

Shipping is quoted per order. Prices on this site are the manufacturer's base list prices and exclude shipping. Single small items shipped across continents are rarely economical; we are set up for wholesale quantities, institutional orders and custom formulations, and we quote the most economical route for each destination.

How shipping is quoted

Tell us the products, quantities and delivery address on the quote page or at checkout. We reply within one business day with the shipping cost, the transit time and any cold-chain requirement. Orders ship by tracked courier (DHL, FedEx, UPS) or, for pallet quantities, by air or sea freight.

Ship-from location

Orders are prepared and dispatched from Shanghai, China (Building 5, 3rd Floor Reception, 657 Guangzhong Road, Shanghai, China).

Lead time

• Catalog products (in stock) — 2-3 business days to dispatch, plus transit time to your country (typically 3-7 business days).
• Catalog products (made-to-order) — 7-14 business days for production, plus standard transit.
• Custom formulations — lead time confirmed at quote (typically 4-8 weeks for first run; faster for repeat orders).
• Bulk and process-scale orders — lead time confirmed at quote.

Temperature control

Temperature-sensitive products (most liquid media, some reagents, all sera) ship cold-chain. Standard cold-chain shipping uses insulated containers with cold packs (2-8°C) or dry ice (-78°C) sized to the destination transit time. Cold-chain packaging and transit are quoted with the order; for cold-chain products we recommend consolidated wholesale shipments.

Tracking

We share a tracking number on dispatch by email. Tracking covers the full transit from our warehouse to your delivery address.

Customs and import

Standard shipping is delivered DAP (Delivered at Place) — customs duties, taxes, and import-clearance fees are the responsibility of the importer of record. For institutional customers we provide the documentation needed for duty-free import where applicable (e.g., research and biological-product classifications).

Damaged or lost shipments

If a shipment arrives damaged or fails to arrive, contact [email protected] within 7 days of expected delivery. We replace damaged or lost product at no charge.

Expedited shipping

Standard expedited options (next-day, 2-day air, special-handling) are available on request through the quote page.
