Ordering and services

To initiate an order for Teklad custom research diets or ingredients, choose one of the following:

Be prepared to provide the following information:

  • Product code (five or six digit number starting with CA or TD)
  • Quantity required (in kg)
  • Diet form (pellet or powder)
  • Additional services (irradiation, vacuum packaging)
  • Bill to address
  • Ship to address
  • Purchase order number or credit card number

  • Order initiator contact information for order confirmation

The minimum order for diets and most ingredients is three kg. The minimum order for vitamin and mineral mixes is 500 grams.

Diets are custom made to fill each order, and are not inventoried. Diets are usually shipped from our production facility ten business days after an order is placed. Transit time depends on the type of delivery method used (regular ground, overnight, etc.). Weight and delivery method affect shipping costs, that are typically added to the invoice.

Outside the USA or Canada
Most European countries, Israel, and Mexico have Envigo affiliates available for help in placing an order. For other countries, prepayment is required via credit card or electronic transfer. It is highly recommended that a customer be aware of any necessary permits and conditions of importation. Trading companies are often very helpful in this regard.

Prices are dependent on formulation (ingredients and complexity), quantity ordered, final product form (powder or cylindrical pellet), and special packaging, processing, or analysis. Contact customer service about current prices for existing product codes, including diet ingredients. Terms are net 30 days. A nutritionist in technical services can assist you with price estimates for new formulas.

Standard packaging includes a small box (9 x 9 x 11 inches) that will fit up to five kg, a medium box (10 x 10 x 15 inches) that will fit up to ten kg, and a larger heavy-duty box (13 x 13 x 20 inches) with inset handles that holds up to 20 kg. Every container also includes a three-mil poly liner to keep your research diet as fresh as possible. Vacuum packaging and specific quantity packaging are also available at additional cost. Vacuum packaging will typically reduce the amount of diet fit into a box.

Most custom research diets do not withstand autoclaving; however, we can arrange for qualified diets to be irradiated. The irradiation dose range is two to five MRad, or 20-50 kGy. Nominal fees and extra time are involved.  Please contact Customer Service for details about irradiation costs and additional lead time. Vacuum packaging may be helpful in reducing irradiation-induced peroxide formation in high fat diets. A nutritionist in Technical Services can assist you in determining if a formula is suitable for irradiation.

Specific chemical analyses can be arranged upon request. The fees from independent testing labs are added to the invoice.

We are careful about the information exchanged with others, and we will consider formal agreements if necessary.
