Tariffs into the USA

Based on recent policy changes, there is a probability that tariffs will be charged.  Crazy Arms deliver the goods Delivery Duty
Unpaid (DDU) to all countries outside of Australia and New Zealand and the UK,
which means the end customer is responsible for paying any duties or taxes upon delivery.

This latest US ruling comes into effect as of August 29, 2025, whereby the U.S. has suspended the"de minimis" duty exemption for all countries. Previously, shipments
valued at USD800 or less could enter the U.S. duty-free.

• Tariff Application: All goods, including
  apparel, shipped from Australia to the USA are now subject to applicable duties
  and taxes, regardless of their value.
• Baseline Tariff: A 10% baseline tariff is
  currently applied to most Australian goods entering the U.S.
• Country of Origin: The tariffs are based on
  the country of origin of the product. 
  Crazy Arms are manufactured in both Australia and China with the same fabric,
  specifications and quality standards.  In
  any one delivery you may receive both made-in-Australia and Made-in-China
  product, depending on the styles and colours you choose.  Made in China products may be subject to a
  30% tariff.

 The Process for Paying Tariffs?

The process for paying tariffs typically rest with the importer, which in this case is our customers in the USA.

• Payment Collection: Tariffs and any
  associated fees are collected by U.S. Customs and Border Protection (CBP) when the package goes through customs clearance.
• Shipping Carrier's Role: The shipping
  carrier (e.g., Australia Post/USPS, FedEx, DHL) often handles the collection of
  these fees on behalf of CBP. They will usually contact the customer to notify
  them of the fees and collect payment before delivering the package.

In summary, for the time being, shipments of apparel under USD80 from Australia to the U.S. will now incur tariffs, and unfortunately the responsibility for paying these fees rests with the customer upon delivery.

We will be keeping a very close watch on how this develops, but we do
anticipate potential delays and costs with deliveries in the short term, as the
system is implemented.
