Before you mail it
- Arrange the submission first. Wait for acceptance, your sample ID, and the confirmed shipping destination. Do not send an unannounced package.
- Label each vial. Include its sample ID and a simple identifier such as the cap color or lot number. Keep multiple vials separate.
- Protect the glass. Make sure the cap is secure. Put the vial in a small sealed bag and wrap it with paper towel, packing paper, or bubble wrap. Cushion it so it cannot rattle against another vial.
- Choose a package. A padded mailer can work for a vial inside a small rigid protective container. A small box is better for several vials or fragile glass. A free USPS Priority Mail box is fine when you are using Priority Mail; fill empty space with crumpled paper or clean paper towels so nothing moves.
- Include the submission sheet. Use the assigned IDs, retain your tracking number, and send us the carrier and tracking details.
Please do not reconstitute a dry sample unless ZAVCO specifically asks you to. If your sample is liquid, temperature-sensitive, damaged, or otherwise unusual, contact us before packing it.
