Contact Dihydrocodeine USA

The fastest way to reach us is email. Average response time is under four hours during US business days, longer on weekends.

Sales, orders, shipping and refunds: sales@dihydrocodeineusa.com

Certificate of Analysis requests: Include your order number and the batch printed on the foil blister. We will reply with the relevant COA as a PDF.

Lost or stuck packages: If USPS tracking has not updated for 5+ business days, email us with the tracking number. We will open a Postal Service trace request the same day. See the refund policy for the full procedure.

We do not operate a phone line. All support is handled by email so both sides have a written record of every order, refund and reship.
