International Shipping
For destinations outside mainland China, shipping — together with any cold-chain or dry-ice surcharge — is quoted per destination and packaging requirement; the free-shipping threshold above does not apply. Duties, import taxes and customs clearance fees are payable by the recipient. We will send you a shipping quote and estimated transit time within one business day of receiving your order, and dispatch only once you have confirmed it.
Cold Chain & Temperature Control
Qihe Biotech applies strict cold-chain logistics management for temperature-sensitive products. We offer the following temperature-controlled shipping options based on storage requirements:
Blue-Ice Cold Chain (2–8°C)
For fluorescent dyes, antibodies and most reagents requiring refrigerated storage. Medical-grade blue ice + insulated box maintains a cold environment for 48 hours.
Dry-Ice Shipping (-20°C / -80°C)
For enzymes, lyophilized products and customer-specified deep-frozen items. Industrial dry ice + high-strength insulated box ensures products arrive still frozen.
Ambient Shipping
For stable lyophilized powders, chemical reagents and other ambient-stable products. Shock-resistant foam packaging provides moisture and impact protection.
⚠️ Summer Heat Advisory:From June to September each year, insulation measures for cold-chain products are automatically upgraded to ensure safe transit in high temperatures. If you notice any issue upon receipt, please contact customer service within 24 hours.
