This Payment Policy explains the payment methods, payment processing, order verification, refunds and payment-related procedures of Chuanhe Energy Storage Systems Co., Ltd., operating under the brand name CHUANHE ESS (“CHUANHE ESS,” “we,” “us,” or “our”).

This policy applies to eligible orders placed through: https://chuanhe-ess.shop .

Wholesale, distributor, OEM, ODM, private-label and project orders may be subject to additional payment terms stated in the applicable quotation, pro forma invoice, purchase agreement or sales contract.

1. Accepted Payment Methods

We currently accept the following online payment methods:

• PayPal: Customers may select PayPal during checkout and complete payment through the PayPal payment interface.
• Credit and debit cards: We accept eligible credit and debit cards supported by the payment provider displayed during checkout.

Available card brands, payment options and authentication methods may vary according to the customer's billing country, issuing bank, device, transaction currency and payment provider.

The payment methods displayed during checkout are the payment methods currently available for that order.

2. PayPal Payments

When PayPal is selected, you may be redirected to PayPal or presented with a PayPal checkout window to review and authorize the transaction.

The payment options available through PayPal depend on your PayPal account, country, account status and the funding sources made available by PayPal.

PayPal payments are also subject to PayPal's own user agreements, privacy policy, security procedures and dispute-resolution rules.

Please ensure that the email address, billing information and delivery address submitted through PayPal are accurate before approving payment.

3. Credit and Debit Card Payments

When paying by card, you may be asked to provide:

• Name of the cardholder.
• Card number.
• Expiration date.
• Card security code.
• Billing address.
• Additional verification required by the issuing bank.

Your bank or payment provider may require an additional verification step, such as a one-time password, banking-app approval or another authentication procedure.

The billing information entered during checkout should match the information registered with the card-issuing bank. Incorrect or incomplete billing information may cause payment authorization to fail.

4. Payment Currency

Product prices and the final transaction currency will be displayed during checkout before payment is submitted.

If your payment card, PayPal account or bank account uses a different currency from the checkout currency, your payment provider may convert the transaction into your account currency.

Currency-conversion rates, foreign-transaction charges and international payment fees are determined by your bank, card issuer or PayPal. CHUANHE ESS does not control these exchange rates or third-party fees.

5. When Payment Is Charged

Depending on our payment-processing settings and the payment provider, your payment may be authorized and captured when:

• You complete checkout.
• Your order is reviewed and accepted.
• Your order enters processing.
• Another payment-capture event permitted by the payment provider occurs.

An authorization verifies that sufficient funds or credit are available. A captured payment is the completed charge applied to the payment method.

Placing an order does not guarantee acceptance. We reserve the right to review, cancel or decline an order before fulfillment where reasonably necessary for payment, security, inventory, compliance or shipping reasons.

6. Authorization Holds and Pending Charges

Your bank or payment provider may place a temporary authorization hold on your account when a payment attempt is made.

A pending authorization is not always a completed charge. If the order is cancelled, declined or not completed, the issuing bank may require several business days to remove the authorization.

The release time for a pending authorization is controlled by the card issuer, bank or payment provider. CHUANHE ESS cannot directly remove a bank authorization hold.

7. Order Confirmation

After an order is submitted, you should receive an order confirmation at the email address provided during checkout.

An automated order confirmation acknowledges that we received your order. It does not necessarily confirm that:

• The payment has passed all verification checks.
• The order has entered production or fulfillment.
• The product is available for immediate shipment.
• The transaction has received final acceptance.

We may contact you if additional information is needed before the order can be processed.

8. Payment Verification and Fraud Prevention

To protect customers and our business, orders may be reviewed for fraud, unauthorized payment activity, sanctions compliance, address inconsistencies or unusual transaction patterns.

We may request reasonable additional information, including:

• Confirmation of the cardholder or PayPal account holder.
• Billing or delivery-address verification.
• Telephone or email confirmation.
• Company information for commercial orders.
• Additional evidence reasonably required by the payment provider.

We will not ask you to send a complete payment-card number or card security code by email.

An order may be delayed or cancelled if the payment cannot be verified, appears unauthorized or presents an unacceptable fraud or compliance risk.

9. Failed or Declined Payments

A payment may be declined for reasons including:

• Insufficient funds or available credit.
• Incorrect card or billing information.
• An expired or restricted card.
• International or online transactions being disabled.
• Bank security controls.
• Payment-provider risk checks.
• Incomplete authentication.
• Technical or network interruptions.

If a payment is declined, please verify the information entered, contact your card issuer or PayPal, or try another available payment method.

For privacy and security reasons, banks and payment providers may not provide us with the exact reason for a declined transaction.

10. Duplicate or Multiple Charges

If you believe you have been charged more than once for the same order, first review whether one of the entries is a temporary pending authorization rather than a completed charge.

If multiple completed charges appear, contact us and provide:

• Your order number.
• The transaction dates.
• The amounts charged.
• The payment method used.
• A screenshot with sensitive card information hidden.

Do not send us your complete card number, PayPal password or card security code.

11. Prices, Discounts and Promotional Codes

The price charged is the price displayed during checkout after any eligible discount has been applied.

Promotional codes must be entered and accepted before payment is completed. Unless expressly stated otherwise:

• Discounts cannot be applied after an order has been completed.
• Discount codes cannot be exchanged for cash.
• Only eligible products and orders qualify.
• Discounts may not be combined.
• Expired promotional codes will not be accepted.

We reserve the right to correct obvious pricing, discount or calculation errors before fulfilling an order.

12. Shipping Charges

Shipping charges, where applicable, are displayed or communicated before the order is finalized.

Eligible online orders with a qualifying merchandise subtotal of US$800 or more may receive free standard shipping where that option is available at checkout.

Express delivery, special handling, lithium-battery transportation, remote-area charges, customs services and commercial freight may require additional payment.

Please review our Shipping Policy for complete shipping terms.

13. Taxes, Duties and Customs Charges

Applicable taxes collected through checkout will be displayed before payment is submitted.

International shipments may also be subject to import duties, value-added tax, customs fees, brokerage charges and other government charges imposed by the destination country.

Unless checkout or a written sales agreement expressly states that such charges are included, the recipient is responsible for applicable import duties, taxes and customs-clearance costs.

14. Refunds

Approved refunds are normally returned to the original payment method used for the order.

We generally process an approved refund within seven business days after the refund is approved or an eligible returned product passes inspection.

After we issue a refund, your bank, card provider or PayPal may require additional time to post the funds to your account.

The time required for a completed refund to appear is controlled by the payment provider and financial institution.

Please review our Return and Refund Policy for information about eligibility, return shipping, inspections, deductions and non-returnable products.

15. Refunds to Expired, Replaced or Closed Cards

Refunds are normally sent to the original payment method even if the card has expired or been replaced.

The issuing bank is generally responsible for directing the refunded amount to the correct replacement card or account.

If the original account has been closed, contact the issuing bank or payment provider for assistance after we confirm that the refund has been processed.

16. Order Cancellations

If an eligible order is cancelled before fulfillment, any captured payment will be refunded to the original payment method.

An authorization that has not been captured may be voided instead of refunded. The issuing bank determines how quickly a voided authorization disappears from the customer's account.

Customized, OEM, ODM, private-label or made-to-order products may become non-cancellable after production, customization, material purchasing or packaging preparation begins.

17. Payment Disputes and Chargebacks

If you do not recognize a payment or believe there is an order problem, please contact us before opening a payment dispute whenever reasonably possible.

We will review the order and attempt to resolve legitimate concerns relating to:

• Unauthorized transactions.
• Duplicate charges.
• Incorrect products.
• Non-delivery.
• Damaged or defective products.
• Approved refunds that have not appeared.

When a chargeback or payment dispute is submitted, we may provide the payment provider with relevant records, including order confirmations, customer communications, payment records, shipping information, delivery confirmation and policy acknowledgements.

Fraudulent chargebacks or knowingly false payment disputes may result in cancellation of current orders, restriction of future purchases and other remedies permitted by law.

18. Payment Security

Online payments are processed through Shopify and the payment providers enabled for our store.

We generally do not directly receive or store your complete payment-card number, PayPal password or card security code.

Customers should only enter payment information through the secure checkout process or an authorized payment-provider interface.

We will never ask you to send your complete card number, card security code or PayPal password through email, social media or messaging apps.

If you receive a suspicious payment request claiming to represent CHUANHE ESS, contact us before making payment.

19. Wholesale, OEM, ODM and Project Orders

Payment terms for wholesale, distributor, OEM, ODM, private-label and project orders may differ from standard Shopify checkout terms.

Commercial payment terms may include:

• Deposit requirements.
• Balance payments before shipment.
• Milestone payments.
• Production and tooling charges.
• Certification and customization fees.
• Separate freight and customs charges.

Any commercial payment schedule must be confirmed in the applicable quotation, pro forma invoice, purchase agreement or sales contract.

A commercial order may not enter production until the required deposit or other agreed payment has cleared.

20. Changes to This Payment Policy

We may update this Payment Policy periodically to reflect changes in payment providers, checkout functions, business operations, security requirements or applicable laws.

The updated policy will be posted on this page with a revised “Last updated” date.
