Shipping

Products will be shipped by FedEx, UPS, DHL, or USPS. All in‑stock items will be shipped within two business days after the order is received. Customers should inspect shipments immediately upon receipt.

Certain orders are subject to a handling charge, which will be added to the invoice. Hitobiotec Corp. is not responsible for duty or customs fees; customers may be invoiced separately for these charges.

Regulated Shipments

The Department of Transportation enforces strict rules regarding packaging and shipping of regulated chemicals. Compliance is mandatory. A hazardous shipping charge will be included in your invoice for materials requiring special HazMat packaging and shipping (e.g., Poison, Corrosive, extremely flammable). We will try to keep this expense to a minimum.

If you have any additional questions, please contact our customer service at 423‑520‑6880 or support@hitobiotec.com.
