Why Ship to NAFA?
The world's largest and oldest Wild Fur Auction, professionally managed and now owned by trappers.
The only auction company willing to spend money to protect your future through international promotion of Wild Fur.
Largest buyer attendance guarantees highest prices and clearances for Wild Fur. Large can be beautiful, especially when it means more buyers bidding.
NAFA offers our shippers on-line access to their accounts. You can securely view receipts, lotting letters, sales summaries and financial statements.
Access your account on our web site by completing our Registration Form.
First-Time Shippers
You do not need to have an account number before sending your skins; an account will be created for you after your first shipment.
Shippers have the option of joining NAFA's Wild Fur Shippers Council (more on WFSC benefits...). As a NAFA shareholder, the WFSC gives trappers a voice in guiding NAFA's operations.
Carefully read "Shipping Info" and "Conditions of Sale" for your country to ensure you know the shipping requirements.
Pelts can be shipped directly to NAFA, dropped off at a NAFA Depot or given to one of our collectors on a pick-up route.
Please be aware of the last receiving dates for each auction, some collectors have earlier last receiving dates.
Pelt Handling information can be found in NAFA's Anniversary 2004 issue magazine.
