Procedural Requirements

First, the basics:

• We do not accept items shipped “collect.”
• For return shipments, specify shipping preference and account number to bill for cost. Otherwise, return shipment is sent collect.
• If a purchase order (PO) is required, submit with documents authorizing tests.
• Payment may be made by credit card (MasterCard, Visa, American Express and Discover accepted).
• Unless an exemption has been approved, international orders require prepayment.
• All sample residues and excess raw materials become the property of the FBRI unless a specific request is made for return.
• To ensure faster fiber preparation and testing, please follow these guidelines:
  • Sample Preparation: Do not use staples or plastic sacks. If sacks need to be closed by folding over; do not use rubber bands.
  • Sample Identification: Limit identification codes to ten digits and use numerals only (no letters, symbols, dots or dashes). If possible, use bar codes.

DATA DELIVERY: Email copies of test data
