Shipping & Returns

Products will be shipped by Fedex, UPS, DHL or USPS.
All of our in-stock items will be shipped within two business days after the order is received. Customers should inspect the shipments immediately upon receipt.
Certain orders are subject to a handling charge and will be added to the corresponding invoice. Hitobiotec Corp. is not responsible for any duty or customs fees and customers may be invoiced separately for these charges.

Regulated Shipments:
In the past year the Department of Transportation has enforced new rules and regulations regarding the packaging and shipping of regulated chemicals. Compliance to these regulations is mandatory. Therefore, a hazardous shipping charge will be included in your invoice for only those materials requiring special HazMat packaging and shipping (Poison, Corrosive, extremely flammable etc.). We will try our best to keep the expense to a minimum.

If you have any additional questions, please contact our customer service at 423-520-6880 or
