Issued by: Kunshan Zhengbai Mechanical&Electronical Co.,Ltd. (hereinafter “Seller”)
Effective Date: April 29, 2026
Scope: All orders placed through zbcharger.com or any written agreement between the parties

Please read these terms carefully. By submitting an order to the Seller, Buyer (hereinafter “Buyer”) is deemed to have read, understood and agreed to be bound by these Terms and Conditions of Sale. If Buyer does not agree to these terms, Buyer shall not place any order for the Products.

§ 1. Definitions and Scope

1.1 These Terms and Conditions of Sale apply to all quotations, order confirmations and supply contracts for the sale of Products between Seller and Buyer, and constitute the entire agreement between the parties.

1.2 “Product(s)” means the goods listed in Seller‘s quotation or order confirmation, including standard packaging and accompanying documents.

1.3 “Written form” includes but is not limited to e-mails, faxes, paper letters, and formal message records of instant messaging tools.

1.4 Any additional or conflicting terms contained in Buyer’s purchase order shall be null and void and have no legally binding effect.

1.5 Seller‘s performance of Buyer’s order shall not be deemed as acceptance of any of Buyer‘s terms and conditions, nor as a modification of these Terms and Conditions of Sale.

§ 2. Quotations and Orders

2.1 Buyer must include a description of the Products, quantity, requested delivery date and shipping address when submitting an order.

2.2 Seller’s quotations are valid for thirty (30) days from the date of the quotation. Seller reserves the right to amend or withdraw a quotation at any time before receiving Buyer‘s acceptance.

2.3 An order becomes binding only upon Seller’s written (including e-mail) order confirmation. If Seller does not issue a confirmation, it shall be deemed that Seller does not accept the order. Seller has the right to accept or reject any order (including partial acceptance) at its sole discretion. Once an order has been accepted, Buyer may not amend or cancel it without Seller‘s prior written consent.

If Buyer unilaterally cancels the order without Seller’s consent after order confirmation, Buyer shall indemnify Seller for the direct losses suffered by Seller (including but not limited to unrecoverable costs already incurred by Seller for performing the order, such as raw material procurement, custom processing fees, etc.). “Unrecoverable costs” means raw materials, parts, molds and dedicated labor costs specially procured or custom‑made for performing the order which cannot be used for other orders.
If the parties agree in writing to cancel the order, the costs already incurred shall be shared by mutual agreement.

2.4 Seller has the right to make partial shipments at its sole discretion; Buyer shall accept partial shipments and pay the corresponding price. The undelivered portion may be cancelled or postponed upon Buyer‘s consent.

§ 3. Prices and Currency

3.1 Base Currency. The base currency for pricing all Products is Renminbi (CNY). Seller’s cost accounting, profit calculation and internal management are all based on Renminbi.

3.2 Front-End Price Display. For the convenience of global customers, the website product pages display both the Renminbi reference price and the US Dollar reference price converted at real-time exchange rates. Foreign currency prices are for reference only and may fluctuate with exchange rates.

3.3 Transaction Currency and Lock-in. Buyer must select the actual settlement currency when placing the order. After order confirmation, the transaction currency and amount are locked and will not be adjusted for subsequent exchange rate changes.

If Buyer chooses Renminbi (CNY) settlement: the amount payable is the Renminbi base price at the time of order confirmation.
If Buyer chooses US Dollar (USD) settlement: the amount payable shall be converted at the US Dollar to Renminbi spot selling rate published by the Bank of China on the date of order confirmation. If that rate is not published on that day, the rate published on the preceding working day shall apply. The converted USD amount, once confirmed, becomes the fixed transaction price.

3.4 Taxes and Duties. Seller shall bear the export customs clearance fees and export duties (if any) required by the laws of China. Buyer shall bear all import customs clearance fees, import duties, value-added taxes and any other taxes, fees or charges imposed in the destination country.

3.5 Price Adjustment. Seller reserves the right to adjust the Renminbi base price at any time. Adjusted prices apply to orders confirmed after the adjustment date.

§ 4. Payment

4.1 Payment Methods. Buyer may pay the full order price by the following methods:
(a) Online instant payment: pay instantly through the online payment methods provided on the website. The order will automatically enter the processing flow after Seller receives confirmation of full payment. Any online payment processing fees shall be borne by Buyer.
(b) Telegraphic Transfer (T/T): pay 100% advance payment by T/T to the bank account designated by Seller. Seller will arrange production and shipment after confirming receipt of the full amount. T/T charges shall be borne by Buyer.

4.2 Payment Conditions. Seller reserves the right to require Buyer to provide additional payment security. For new customers or large orders, Seller may require full payment before production.

4.3 Late Payment. If Buyer fails to pay the full advance payment within 10 working days after order confirmation, Seller has the right to notify Buyer in writing to cancel the order and claim compensation for the direct losses suffered by Seller. Upon cancellation, Seller is entitled to estimate the amount of direct losses and deduct such amount from the paid advance payment, returning the remaining balance within thirty (30) days; Seller shall provide Buyer with a detailed statement of losses within fifteen (15) working days after the deduction. Any discrepancy shall be settled separately by the parties.

4.4 Costs of Enforcement. If Seller takes legal action to recover payment due to Buyer‘s default, Buyer shall bear all costs incurred by Seller, including but not limited to attorneys’ fees, litigation costs, preservation fees, enforcement fees, travel expenses and any other costs of enforcement.

§ 5. Delivery and Risk of Loss

Depending on the mode of transport chosen by Buyer, different Incoterms 2020 shall apply. Seller‘s obligation ceases upon delivery of the goods to the carrier designated by Buyer within China.

Sea: FOB (named loading port). Seller’s delivery point is the named loading port in China. Risk transfers when the goods are loaded on board the vessel named by Buyer.
Air: FCA (carrier named by Buyer). Seller‘s delivery point is the named airport cargo terminal in China. Risk transfers when the goods are delivered to the carrier named by Buyer.
Rail: FCA (carrier named by Buyer). Seller’s delivery point is the named rail departure station in China. Risk transfers when the goods are delivered to the carrier named by Buyer.

5.1 Once the goods are delivered to the carrier at the above risk transfer point, all risk of loss, damage, deterioration, delay, theft or any other form of loss of the goods shall pass entirely to Buyer. Seller shall not be liable for any loss occurring after the risk transfer.

5.2 Seller is only responsible for packing the goods in a reasonable manner before the risk transfer point and ensuring that the goods conform to the order at the time of delivery to the carrier. Seller shall not be liable for any liability during carriage, including but not limited to transit delay, damage to goods, carrier insolvency, transport accident, weather effects, customs inspection losses, etc.

5.3 Buyer shall decide at its own discretion whether to insure the goods, and shall purchase adequate insurance for the goods during carriage at its own expense. Seller is not responsible for arranging insurance.

5.4 If loss occurs after risk transfer, Buyer shall claim directly against the carrier. Seller may, upon Buyer‘s request, provide necessary supporting documents to assist Buyer in its claim, but Seller itself shall not bear any compensation liability.

5.5 Delivery Time. After receiving and confirming receipt of 100% advance payment, Seller shall negotiate with Buyer in writing to determine the estimated delivery time, taking into account the order quantity, production schedule and availability of raw materials. The parties shall negotiate in good faith.
If Seller is unable to complete production within the agreed delivery time due to Seller’s own reasons, Seller shall promptly notify Buyer in writing and negotiate a new delivery time. Buyer shall not cancel the order, demand a refund or claim any compensation solely on the ground of delivery delay.
If Seller is genuinely unable to perform the order due to its own objective reasons (including but not limited to insufficient production capacity, shortage of raw materials, technical failures, etc.), Seller has the right to unilaterally cancel the order and, after deducting the unrecoverable costs already incurred (including but not limited to specially procured raw materials, custom processing fees, dedicated labor costs, etc.), return the remaining amount to Buyer within thirty (30) days. Seller shall provide Buyer with corresponding cost evidence (invoices, time records or copies of procurement contracts).
Any delay caused by force majeure or Buyer‘s reasons (such as failure to provide necessary information in time, payment delay, etc.) shall not be the responsibility of Seller, and the delivery time shall be extended accordingly.

6.4 For latent defects that could not be discovered during reasonable inspection, Buyer shall notify Seller in writing within seven (7) working days after discovery, and in any event no later than the warranty period.

If Seller otherwise agrees in writing to accept a return for non-quality reasons, Seller is entitled to charge a restocking fee of 15% to 25% based on its assessment of the condition of the returned Products.
