Effective Date: June 29, 2026

These Terms of Service constitute a legally binding agreement between this website and all users who access, browse, inquire, and conduct business cooperation via the site. By accessing this website, submitting inquiries, or consulting on products and cooperation matters, you fully acknowledge, understand, and unconditionally agree to be bound by all clauses herein. If you do not accept any part of these Terms, you must immediately cease all use of this website’s services.

These Terms, together with our Privacy Policy, Return & Refund Policy, and Shipping Policy, form a complete set of business service regulations. All users utilizing the website’s services shall fully comply with the above provisions.

1. User Qualification and Usage Rules

Cooperating users must be legally registered business entities or individuals with full civil capacity, capable of independently bearing all legal and commercial liabilities arising from business cooperation. Minors are not eligible to use the website’s inquiry and cooperation services and are prohibited from conducting any relevant business activities through the site.

If you register an account on this website, you shall independently keep your account, password and verification information confidential and bear full legal and commercial responsibility for all inquiries, consultations and business intentions under your account. You shall not lend, rent or trade your website account. In case of abnormal login, account theft or information leakage, you shall take timely self-rescue measures and contact us for assistance.

You warrant that all corporate information, contact details, delivery addresses and qualification materials submitted on this website are true, accurate, valid and complete. You shall be solely responsible for all consequences arising from false, invalid or incomplete information, including delayed inquiries, terminated cooperation, performance abnormalities and after-sales disputes. We reserve the right to suspend services, freeze accounts and terminate cooperation qualifications without liability.

2. Product Information and Content Specifications

All product images, parameters, specifications, craftsmanship, performance and introductions displayed on this website are for reference only and compiled to ensure authenticity and accuracy. Slight differences between physical products and webpage displays may exist due to shooting light, screen color deviation, manual measurement errors, product batch updates and process fine-tuning. Such reasonable discrepancies shall not be deemed product quality issues and are hereby accepted by the user.

We reserve the right to correct errors, omissions and deviations in webpage information without prior notice, and to update product information, parameters and page content independently based on product upgrades, category adjustments and market changes. All online content on this website is merely for business consultation reference and does not constitute any commercial commitment, offer or legal guarantee.

All products displayed on the website are legally compliant commodities. You undertake that all products consulted and purchased through the website shall be used for legitimate production and business purposes only. Any illegal production, transaction, processing or other unlawful application is strictly prohibited, and you shall bear all legal liabilities arising from irregular use.

3. Quotation, Transaction and Performance Rules

All online product prices displayed on the website are reference quotations only and do not represent final transaction prices. They do not include international logistics fees, customs duties, clearance fees, customization charges, service fees and other additional expenses. The final transaction price, detailed fees, cooperation terms and performance standards shall be subject exclusively to the written quotations, Proforma Invoices (PI) and formal sales contracts issued by our authorized business personnel and confirmed by both parties.

We may update online reference prices independently according to market fluctuations, raw material cost changes, capacity adjustments and promotional policies without prior notice. Price adjustments apply only to online display and shall not affect the validity of confirmed written quotations and signed contracts. All locked cooperation terms shall be governed by bilateral written agreements.

This website is a B2B enterprise display and business inquiry platform and does not provide any online payment, online deduction or online transaction functions. All business cooperation is conducted through offline negotiation, written confirmation and bank transfer between corporate accounts. After you submit an inquiry or cooperation intention, our professional sales team will follow up with negotiations, confirm cooperation details and issue official transaction documents. Production, payment and delivery shall be performed strictly in accordance with signed formal contracts.

Any incorrect online reference prices, product parameters or cooperation information caused by system failures, abnormal page display or manual entry errors shall have no transaction validity. Final cooperation standards shall be subject to bilateral written confirmation documents, and we shall not be liable for disputes or losses arising from such information deviations.

4. Inquiry and Order Confirmation Mechanism

Submission of product inquiries, cooperation intentions or procurement demands on this website constitutes only a business consultation invitation and does not form a valid purchase order or legally binding transaction contract. All official orders shall take effect only after bilateral negotiation, confirmation of cooperation details, signing of Proforma Invoice or sales contract, and completion of payment by the buyer, before entering production, stocking and delivery procedures.

We retain independent rights of inquiry review and order acceptance. We may terminate consultations, refuse orders or suspend cooperation for legitimate reasons, including but not limited to insufficient production capacity, stock shortage, product upgrading and removal, webpage information errors, false inquiries, malicious quotation solicitation, fraud risks, undeliverable destinations, and violations of these Terms or compliance requirements.

Before an official order enters production, stocking or delivery procedures, either party may negotiate to modify or terminate cooperation. No unilateral cancellation is permitted once production, stocking or delivery has commenced. Any modification or termination shall be implemented strictly in accordance with the signed formal contract. For cooperation terminated legally by us, follow-up refund and settlement procedures shall be handled in accordance with contractual provisions.

5. Logistics, Delivery and Risk Rules

We only provide logistics and delivery services to countries and regions confirmed as deliverable by both parties. Shipping fees and transit times vary by destination and logistics channel, subject to final contractual agreements and actual logistics execution.

All delivery times displayed on the website are estimated durations for reference only and do not constitute a guaranteed delivery commitment. We shall not be liable for any delays or losses caused by uncontrollable factors including customs inspection, international logistics congestion, extreme weather, public emergencies, policy adjustments and holiday suspensions.

All cross-border tariffs, value-added taxes, customs clearance fees, inspection charges and overdue fines incurred in the destination country shall be borne solely by the buyer. We shall not be responsible for reshipment, compensation or refunds if parcels are returned, invalidated, damaged or lost due to the buyer’s refusal of signature, failure to complete customs clearance or incomplete qualification documents.

Once goods are picked up and signed for by the logistics carrier, all risks of custody, damage or loss of products shall be fully transferred to the buyer. All subsequent logistics abnormalities shall be resolved by the buyer through negotiation with logistics providers and local customs authorities.

6. Return, Refund and After-Sales Policy

All after-sales return and refund applications must be submitted in writing within 14 calendar days after product delivery and acceptance. Any after-sales claims exceeding this time limit may be rejected by us.

Only brand-new, unused, unmodified and undamaged products with original packaging, accessories and complete documents that remain resalable are eligible for return application. Final return eligibility shall be subject to our official inspection and verification.

The following items are not eligible for non-reason returns and shall not be returned or exchanged once production or shipment is initiated: customized non-standard products, personalized products, clearance discount products, disposable consumables, hygiene products, technical service products and store credit/gift card products.

After we receive and verify returned goods and confirm compliance with after-sales conditions, refunds will be processed via the original payment channel within 5 to 10 working days. The actual arrival time depends on bank and third-party settlement rules, for which we make no time-bound guarantees.

Original logistics shipping fees are non-refundable. Return shipping fees shall be borne by the buyer for returns caused by personal reasons. We shall bear return shipping fees only for problems attributable to us, including incorrect shipment, original quality defects, and specification inconsistencies.

7. Intellectual Property Protection

All website text content, page layouts, logos, product images, videos, technical descriptions, parameter materials and design achievements are legally protected intellectual property works.

Without prior written authorization from us, no user, institution or third party may copy, repost, modify, intercept, commercially use or disseminate any website content. Malicious crawling, data scraping and unauthorized data acquisition are strictly prohibited. We reserve the right to pursue full legal liability for all infringing acts.

8. User Code of Conduct

When using the website for inquiry and business cooperation services, users shall abide by national laws, regulations and business integrity principles. The following behaviors are strictly prohibited: malicious frequent inquiries, false cooperation consultations, unauthorized quotation solicitation and data collection, website data crawling, fraudulently using others’ business qualifications, conducting illegal transactions, and initiating malicious disputes or unreasonable after-sales claims that damage our legitimate rights and interests.

In case of any prohibited behaviors, we have the right to terminate consultation and cooperation immediately, block user access, refuse future cooperation permanently, and reserve the right to pursue legal remedies.

9. Disclaimer of Liability

This website and all services and product information are provided on an “as is” basis. We do not guarantee uninterrupted, error-free, secure or flawless website operation at all times. We shall not be liable for any direct or indirect losses caused by network fluctuations, system maintenance, equipment failures, third-party platform abnormalities or force majeure events that result in inquiry delays or abnormal webpage access.

This website serves only as a product display and business docking platform. We assume no liability for users’ business profits, expected returns, operational losses or commercial risks. All B2B cooperation performance standards, liability division and risk allocation shall be subject exclusively to the formal signed sales contract between both parties.

10. Policy Revision and Update

We reserve the right to revise, supplement and update these Terms of Service at any time. Revised clauses shall take effect immediately upon website publication with an updated revision date, without separate individual notification. Your continued website access, inquiry submission and business cooperation shall constitute acceptance of the latest Terms.

11. Dispute Resolution

All disputes arising from website services, business consultations and contract performance shall first be settled through friendly negotiation based on the principle of good faith. If negotiation fails, disputes shall be resolved in accordance with the dispute resolution clauses stipulated in the signed formal sales contract. In the absence of contractual agreements, disputes shall be handled in accordance with applicable laws and regulations.
