At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.

Ambient temperature shipping helps to control shipping costs for our customers. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. How does the storage temperature relate to shipping conditions?
