How long is the typical delivery time?

The delivery time for imported industrial spare parts primarily depends on the brand's country of origin, whether the product is a standard stock item, the manufacturer's production schedule, and international logistics efficiency. Below are general delivery time references:

• Standard Models in Stock: Ruilianxin maintains regular stock or can coordinate overseas stock for some popular brand models, reducing delivery to 1-2 weeks.
• Regular Orders: Most standard models have a delivery time of 4-8 weeks, including manufacturer production scheduling (2-4 weeks), international shipping (1-2 weeks), and customs clearance.
• Custom/Special-Order Items: Special parameter or custom models require confirmation based on the manufacturer's production plan, typically 8-16 weeks.

Ruilianxin will clearly state the estimated delivery time at the quotation stage and provide regular progress updates during order execution. We understand the importance of spare parts delivery to customer production and will make every effort to coordinate expedited channels to shorten waiting time.

How can I ensure products are genuine?

Authenticity assurance is Ruilianxin Technology's core commitment. We ensure every product is genuine through the following methods:

• Direct Source Procurement: Procured directly from European and American manufacturers or first-tier authorized distributors, without middlemen, eliminating risks of refurbished, counterfeit, or salvaged parts.
• Traceable Documentation: We can provide manufacturer shipping documentation (order confirmations, shipping invoices), original serial number traceability, and original packaging with certificates of conformity/factory test reports.
• Tenfold Compensation Guarantee: Backed by our business reputation, we promise tenfold compensation if any product is found not to be genuine.
• Customer Verification: After receiving products, customers can verify serial number authenticity through the brand's official website or by contacting the manufacturer's customer service.

Over the past decade, Ruilianxin Technology has served more than 500 enterprise customers with zero genuine product quality issues — this is the foundation of the long-term trust we've built with our clients.

How to inquire without a complete model number?

Many customers only have nameplate information from equipment, partial markings on old parts, or just know the brand and approximate parameters without a complete product model when inquiring. This is very common, and Ruilianxin has multiple ways to help you confirm the model:

• Nameplate/Label Identification: Send photos of equipment nameplates or product labels to us, and our technical team can identify the model based on brand characteristics and coding rules.
• Parameter Reverse Lookup: Provide key parameters (such as voltage, interface type, range, dimensions) combined with brand selection manuals for model matching.
• Equipment Model Reverse Deduction: Tell us the complete equipment model and brand, and we can deduce the corresponding component models from the equipment manufacturer's spare parts list.
• Sample Submission: For old parts that truly cannot be identified through information alone, samples can be sent for physical comparison and confirmation.

Even if there is uncertainty about the final confirmed model, we will fully communicate with you before quoting to ensure technical parameters are correct before proceeding with procurement.

How are customs duties and shipping costs calculated?

Customs duties and shipping costs for imported industrial products are important components of total procurement cost. Ruilianxin provides a transparent fee structure:

• Quotation Method: Our standard quotation is a CNY DDP (Delivered Duty Paid) price, already including product price, international shipping, import duties, and VAT. Customers do not need to handle customs clearance themselves.
• Tariff Rates: Industrial sensors, encoders, connectors, and similar products typically have relatively low import tariff rates (mostly between 0%-7%), subject to customs HS code classification.
• VAT Invoices: We can issue special VAT invoices (13% rate), which customers can use for input tax deduction.
• Trade Term Options: If customers have import/export qualifications and wish to handle customs clearance themselves, EXW (Ex Works) or FCA (Free Carrier) trade terms are also available, with our assistance in providing clearance documentation.

Payment Methods and Credit Terms

We offer flexible and diverse payment options to accommodate different customer procurement processes:

• Standard Plan: 30%-50% deposit upon contract signing, with the balance settled before shipment.
• Long-Term Cooperative Customers: Can apply for 30-day or 60-day monthly settlement terms, with credit limits determined based on cooperation history and credit assessment.
• Large Projects: Installment payment plans can be negotiated, with settlement by project milestones.
• Settlement Methods: We support corporate bank transfers and accept both RMB and USD settlements. Payments are made to Ruilianxin Technology's corporate account, ensuring safety and compliance.

After-Sales and Warranty Policy

All imported industrial products purchased through Ruilianxin Technology enjoy manufacturer warranty service:

• Warranty Period: Standard warranty period is 12 months from the date of shipment. Some brands offer 18-24 month extended warranties.
• Warranty Scope: Covers design, material, and manufacturing defects of the product itself. Damage caused by improper use, incorrect installation, use beyond specified ranges, natural disasters, or human damage is not covered.
• After-Sales Process: When customers discover issues, contact Ruilianxin. We assist in submitting after-sales applications to the manufacturer and coordinate repair, replacement, or return solutions.
• Receipt Inspection: We recommend customers complete visual inspection and quantity verification within 7 business days of receiving goods, and promptly report any issues.

What is the minimum order quantity?

Ruilianxin Technology understands the "many varieties, small batches" characteristic of industrial enterprise spare parts procurement, and therefore implements a flexible minimum order quantity policy:

• 1 Piece Minimum: The vast majority of products support single-piece ordering with no need to bundle or force bulk purchases.
• Minimum Order Amount: Some brands or special channels may have minimum order amount requirements (typically ¥500-2,000 CNY), which we will communicate in advance at quotation.
• Multi-Variety Consolidated Procurement: For multi-variety, small-batch spare parts needs, different brands and models can be consolidated into a single order for unified procurement, sharing international logistics and reducing per-unit allocated costs.
• Tiered Pricing: For customers with bulk requirements, larger quantities can enjoy better pricing, negotiated and confirmed at quotation.
