Last updated: 17/02/2026

These Website Terms & Conditions ("Site Terms") govern access to and use of the C4Cu / Cooper 4 Copper website and platform ("Platform"), operated by A42C Ltd ("C4Cu", "we", "us", "our").

They apply only to use of the Platform and do not replace or override the terms governing copper transactions, which are set out separately in the Governing Documents (defined below).

By accessing, browsing, or using the Platform, you confirm that you have read, understood, and agree to be bound by these Site Terms. If you do not agree with any part of these Site Terms, you must not use the Platform.

1. About Us

1.1 C4Cu / Cooper 4 Copper is an online platform operated by A42C Ltd, a company registered in England and Wales (Company No. 16627000), with its registered office at 27 Old Gloucester Street, London, WC1N 3AX.

1.2 The Platform enables users to access information about, and enter into agreements for, the purchase, allocation, sell-back, and physical delivery of LME Grade A copper cathodes.

1.3 C4Cu is not a bank, exchange, brokerage, investment platform, or regulated financial services provider. The Platform is a technical interface only. All copper sales and contractual obligations are entered into between the Buyer and the Seller (A42C Ltd) under the Governing Documents.

2. Scope of These Site Terms

2.1 These Site Terms govern:

Access to and use of the Platform
Account registration and management

The Privacy & Cookie Policy

2.3 In the event of any conflict between these Site Terms and the Governing Documents, the Governing Documents shall prevail to the extent of the inconsistency.

All activity that occurs under your account, whether or not authorised by you
Notifying C4Cu immediately at support@c4cu.com if you become aware of any unauthorised access to or use of your account

4.3 You must not share your login credentials with any third party or allow any other person to access your account. C4Cu shall not be liable for any loss arising from your failure to comply with this requirement.

4.4 C4Cu reserves the right to refuse registration, suspend, or terminate any account at its discretion, including where it reasonably suspects that account information is inaccurate, incomplete, or fraudulent.

4.5 Each individual may hold only one (1) account on the Platform. The creation of multiple accounts by the same individual is prohibited and may result in the suspension or termination of all associated accounts.

5. Communications & Notifications

5.1 By registering an account, you consent to receive communications from C4Cu by email to the email address associated with your account. These communications may include, but are not limited to:

Transaction confirmations and receipts
Account status notifications (including dormancy warnings)
Changes to these Site Terms or the Governing Documents
Security alerts and verification requests
Service updates and maintenance notices

5.2 It is your responsibility to ensure that:

The email address associated with your account is current, valid, and actively monitored
Emails from C4Cu (including from the domains c4cu.com and cooper4copper.com) are not filtered into spam, junk, or other folders that you do not regularly check
You add C4Cu email addresses to your safe sender or whitelist to prevent misdelivery
You update your email address promptly via the Platform if it changes

5.3 C4Cu shall not be responsible for communications that are not received or not read due to incorrect email details, spam filtering, full inboxes, or any other reason outside of C4Cu's control. Notifications shall be deemed delivered when sent by C4Cu to the email address on record, regardless of whether they are actually received or read by the user.

5.4 Notwithstanding Section 5.3, in relation to Dormant Account notifications specifically (see Section 6), C4Cu commits to making reasonable efforts to contact users via multiple channels where possible, as further described in Section 6.

6. Dormant Accounts

6.1 Purpose: The dormant account provisions exist to manage inactive accounts, ensure the security of the Platform, and comply with applicable regulations. They are not intended to penalise long-term holders of copper. Users who maintain periodic activity on their accounts (as described below) will not be affected by these provisions.

6.2 Definition of Activity: For the purposes of this Section, "activity" means any of the following actions performed by the account holder:

Logging in to the Platform (including via the website or any associated application)
Completing a purchase, sell-back, or delivery request
Contacting C4Cu support in writing (email or through the Platform)
Updating account information or settings
Responding to any communication from C4Cu that requires acknowledgement

6.3 Dormancy Classification: An account shall be classified as Dormant where there has been no activity (as defined in Section 6.2) for a continuous period of twelve (12) months.

6.4 Notification Process: Before an account is classified as Dormant, C4Cu will make the following notification efforts:

First Notice (Month 9): Approximately nine (9) months after the last recorded activity, C4Cu will send a courtesy reminder to the email address on record, advising the user that their account is approaching dormancy and that a simple login will reset the inactivity period.
Second Notice (Month 11): Approximately eleven (11) months after the last recorded activity, C4Cu will send a formal dormancy warning to the email address on record, clearly stating the date on which the account will become Dormant and the consequences of continued inactivity.
Final Notice (Month 12): Upon classification as Dormant, C4Cu will send a confirmation notice to the email address on record, advising the user that the account has been classified as Dormant and explaining the reactivation process and applicable fees.

C4Cu will make reasonable efforts to deliver these notices successfully. However, as set out in Section 5.3, C4Cu cannot guarantee delivery where the user's email address is invalid, the user's inbox is full, or emails are filtered by the user's email provider. It remains the user's responsibility to ensure their contact details are current and that C4Cu communications are not filtered.

6.5 Reactivation (12–24 Months): Between twelve (12) months and twenty-four (24) months of inactivity:

The user may request reactivation of the account by contacting C4Cu at support@c4cu.com
A reactivation fee of USD $75 (or local currency equivalent) shall apply, as set out in the Fee Schedule
Reactivation is subject to completion of any required identity verification (KYC) and confirmation of current account details
Upon successful reactivation, the account shall be restored and all allocated copper positions shall be fully reinstated, subject to deduction of any fees lawfully due under the Governing Documents
The reactivation fee is non-refundable once the account has been reactivated

6.6 Account Closure (24+ Months): Where an account remains inactive for a continuous period of twenty-four (24) months:

The account shall be permanently closed
All allocated copper associated with the account shall be forfeited to C4Cu
No compensation, payment, or credit shall be due to the user

Before permanent closure and forfeiture, C4Cu will send a final closure notice to the email address on record, providing a minimum of thirty (30) days' notice of the intended closure date. During this 30-day notice period, the user may still reactivate the account by contacting C4Cu and paying the applicable reactivation fee.

6.7 Safeguards for Long-Term Holders: C4Cu recognises that some users may wish to hold copper allocations over an extended period without actively transacting. To avoid dormancy classification, users need only perform one (1) of the qualifying activities listed in Section 6.2 at least once every twelve (12) months. A simple login to the Platform is sufficient to reset the inactivity period.

6.8 Exceptional Circumstances: Where a user can demonstrate that their failure to maintain activity was due to exceptional circumstances beyond their reasonable control (such as serious illness, incapacity, natural disaster, or military deployment), C4Cu may, at its sole discretion, consider a request for reinstatement of a closed account and any forfeited copper. Such requests must be made in writing to support@c4cu.com with supporting evidence. Any reinstatement granted under this provision is entirely at C4Cu's discretion and shall not create a precedent or obligation to grant similar requests in the future.
