Q: You ship all over the world, How are customs duties and taxes handled?


Our standard terms are CIF from our California facility, we do provide customs compliant paperwork. We can ship collect to your account where all shipping and duties will be charged directly to our shipping account (there is a $15 customs paperwork charge). This is the best method to minimize customs delays.

If you check out through our standard website checkout you will be charged for transportation charges, and your order will be shipped DDU (Delivery Duty Unpaid). You will still receive a separate bill from the carrier for any customs and VAT charges associated with the import of the material these charges are your responsibility.

On special request we can provide you with a quote for DDP (delivery duty paid), where we will charge you for all shipping and customs duties.
