Help & policies

Prices update every 60 seconds based on COMEX spot rates. We apply a transparent premium over spot for manufacturing and handling. You can view the live premium breakdown on product pages.

Once you reach the checkout, your price is locked for 5 minutes to complete the transaction. If the timer expires, the page will refresh with the current market rate.

We accept Bank Transfer (cleared funds required before dispatch) and POLi for instant bank payments. Credit cards are currently not accepted for bullion purchases due to processing fees.

Yes, unlike investment gold or silver, copper bullion is subject to standard 15% GST in New Zealand. All prices shown in the cart will explicitly state the GST component.

All shipments are sent via fully insured, signature-required couriers. Discreet packaging is used. Insurance covers the package until it is signed for at the destination address.

For bulk wholesale orders (100kg+), please allow a 4-week lead time for production runs and logistical handling. Contact the trade desk for precise scheduling.

We primarily serve the NZ market. International shipping enquiries for bulk orders are handled on a case-by-case basis. Export compliance and incoterms will apply.

Store in a cool, dry place. Avoid high humidity to slow down the natural oxidation process. We recommend keeping them in their original plastic sleeves if pristine appearance is desired.

Copper is a reactive metal. Natural tarnish or patina (darkening or green hues) over time is normal and does not affect the metal's intrinsic value or purity (99.9%).

We offer a buyback programme for Global Copper branded bars. Items must be verified upon receipt. Payment is issued within 2 business days of physical verification.

The buyback price is based on the live COMEX spot rate minus a processing spread. You can lock in a buyback price over the phone before shipping the goods to us.
