OSYRIS ships within the contiguous United States only. That policy is not arbitrary. It reflects the fact that domestic shipping of research chemicals is far simpler than international export, both from a regulatory and a product-integrity perspective.

Inside the US, standard carriers such as UPS, USPS, and FedEx can handle ordinary research-chemical shipments with appropriate labeling. International shipments are different: customs classifications, import permits, country-specific restrictions, and clearance delays all add compliance and product-risk complexity.

Peptides are also shipping-sensitive products. Domestic overnight and 2-day delivery windows make it possible to manage temperature-conscious packaging more reliably. International routes introduce customs holds, handoffs, and unpredictable delays that can compromise temperature-sensitive material.

That matters even when the underlying legal framework might allow an export. A shipping policy has to account for product condition, not just paperwork.

OSYRIS focuses on a compliant US domestic shipping footprint rather than trying to navigate every country's import rules. We also do not support re-exporting or informal forwarding arrangements as a workaround for international delivery limits.

If your institution or team needs international research-chemical movement, the right answer is to work through the import and customs rules that apply in the destination jurisdiction rather than assuming domestic rules carry over.
