3.1 Quotations. All quotations issued by EOSYS are valid for the period specified therein. Unless otherwise stated in writing, quotations are valid for thirty (30) calendar days from the date of issue. Quotations do not constitute a binding offer until an order is confirmed by both parties.

3.2 Order Confirmation. An order is deemed confirmed only upon written acknowledgment by EOSYS (via email, signed proforma invoice, or formal purchase contract). Verbal agreements or informal communications do not constitute binding orders.

3.3 Order Modifications. Any modifications to a confirmed order (including but not limited to quantity changes, specification adjustments, delivery schedule changes) must be submitted in writing and are subject to EOSYS approval. Additional costs arising from order modifications shall be borne by the Client.

3.4 Minimum Order Quantities. Certain products and customization services are subject to minimum order quantities (MOQ). MOQ requirements will be communicated during the quotation process and may vary based on product type, customization level, and material specifications.

4.1 Currency. Unless otherwise agreed in writing, all prices are quoted in United States Dollars (USD) or Chinese Yuan Renminbi (RMB) as specified on the proforma invoice.

4.2 Payment Terms. Standard payment terms are as follows unless a separate agreement is in place:

4.4 Taxes and Duties. Prices quoted are Ex-Works (EXW) or FOB unless otherwise stated. Import duties, taxes, customs clearance fees, and any other charges imposed by the destination country are the sole responsibility of the Client.

5.1 Sample Approval. For custom and OEM/ODM orders, EOSYS will produce pre-production samples for Client approval. The Client must review and provide written approval or feedback within fourteen (14) business days of receiving samples. Failure to respond within this period may result in production delays.

5.2 Sample Retention. Upon Client approval, EOSYS will retain sealed reference samples in our engineering and quality departments. These reference samples serve as the benchmark for batch production quality inspection.

5.4 Non-Refundable Custom Orders. Due to the bespoke nature of custom-manufactured products (including but not limited to custom keyway profiles, proprietary pin configurations, branded key heads, and specific cylinder structures), custom orders are non-cancellable and non-refundable once production has commenced.

6.1 EOSYS Patents and IP. EOSYS holds over 100 patents worldwide, including EU invention patent EP4411093A1, multiple WIPO PCT filings, and numerous Chinese invention patents.
