High-quality products tailored for wholesalers and distributors worldwide.
China Loong Generator Co., Ltd. supplies diesel generator sets, generator spare parts, and related products for international B2B customers. Our product range includes portable, residential, commercial, industrial, standby, prime power, silent, open-frame, containerized, trailer-mounted, air-cooled, and water-cooled diesel generators. The following guide explains our standard process from inquiry and specification review through production, shipment, and after-sales communication.
Please send us your application requirements so that we can recommend a suitable generator model or prepare a quotation based on your requested specifications. For an accurate assessment, your inquiry should include as much of the following information as possible:
For diesel generator spare parts or auto connectors, please provide the part number, dimensions, photographs, compatible equipment information, and required quantity whenever available.
Customization can be discussed according to the generator type, application, quantity, and technical feasibility. Options may include power configuration, voltage and frequency, control panel functions, enclosure design, color, branding, sockets, fuel tank arrangement, trailer configuration, packaging, and selected accessories.
After reviewing your requirements, China Loong Generator Co., Ltd. will provide a quotation describing the proposed model, main specifications, quantity, unit price, packaging, applicable trade terms, estimated production schedule, and quotation validity. Pricing may vary according to technical configuration, customization, raw material conditions, order quantity, testing requirements, shipping arrangements, and destination.
Any tooling, design, sample, inspection, documentation, or special packaging costs will be stated separately when applicable. Buyers should review the full quotation rather than relying only on a preliminary or verbal price indication.
Before an order is confirmed, both parties should review the technical information carefully. The review may cover rated output, voltage, frequency, phase, speed, engine and alternator configuration, cooling method, control system, dimensions, noise-control requirements, accessories, labels, manuals, and packaging.
If a sample or pre-production unit is required, the sample specifications, cost, payment, evaluation method, and delivery arrangement will be confirmed separately. Approval of a sample does not automatically confirm a bulk order unless the relevant commercial documents have also been accepted.
An order is considered confirmed after the buyer and seller have agreed on the product specifications, quantity, pricing, payment terms, delivery terms, packaging, and other relevant conditions, and the required order documents have been accepted.
Depending on the transaction, confirmation documents may include a quotation, proforma invoice, purchase order, specification sheet, drawing, packaging artwork, label file, or other written approval. Buyers should verify the following details before approval:
Any requested change after order confirmation may affect price, production progress, packaging, or delivery time. Changes must be reviewed and approved in writing before implementation.
Payment terms are determined according to order value, product configuration, customization requirements, production arrangement, and the agreed commercial terms. The applicable payment schedule, currency, beneficiary information, and payment method will be shown in the quotation or proforma invoice.
Production and shipment arrangements are subject to receipt of the agreed payment and completion of any required technical approvals. Bank charges and other transaction fees are handled according to the confirmed order terms.
To reduce payment risk, buyers should use only the beneficiary details stated in official documents issued by China Loong Generator Co., Ltd. Any request to change payment information should be verified through an established communication channel before funds are transferred.
Production is arranged according to the confirmed specifications and order schedule. For customized generator sets, production may begin after the required payment, technical documents, artwork, drawings, or samples have been approved.
Estimated completion and delivery times depend on product type, quantity, component availability, customization, testing, packaging, and logistics conditions. Any schedule provided before final order confirmation is an estimate and may be updated according to actual order requirements.
During production, relevant progress updates, photographs, specification confirmations, or document checks may be provided when agreed. Buyers should respond promptly to approval requests to avoid delays caused by pending technical, branding, or packaging decisions.
Products are checked according to the confirmed order specifications and applicable inspection arrangements. Depending on the product and order requirements, checks may include appearance, assembly, key dimensions, electrical configuration, control functions, operating condition, accessories, labels, and packaging.
If the buyer requires third-party inspection, pre-shipment inspection, witnessed testing, or a specific test procedure, this requirement should be stated before the order is confirmed. Related costs, scheduling, access, documentation, and acceptance criteria are subject to separate agreement.
Inspection results should be evaluated against the specifications and acceptance requirements confirmed for the order. Requirements introduced after production has started may require additional review and may affect cost or schedule.
Packing is selected according to the generator model, product dimensions, weight, transportation method, destination, and buyer requirements. Depending on the product, packaging may include cartons, protective materials, pallets, wooden packing, or other suitable export arrangements.
Special requirements for logos, shipping marks, barcodes, labels, manuals, spare-parts kits, moisture protection, or reinforced packaging must be provided before production or packing begins. Artwork and marking information should be supplied in a usable format and approved in writing.
Where wooden packaging or destination-specific packing treatment is required, the arrangement will be confirmed according to the order details and applicable import requirements.
Orders may be shipped by sea, air, courier, rail, road, or a combined transport solution, depending on cargo size, urgency, destination, and cost considerations. The selected Incoterm, port or place of delivery, freight responsibility, and insurance arrangement will be stated in the confirmed commercial documents.
Freight quotations and transit estimates may change because of carrier availability, route conditions, fuel adjustments, seasonal demand, customs procedures, or other logistics factors. Shipment will be arranged according to the confirmed order and payment status.
Documents may include a commercial invoice, packing list, bill of lading, airway bill, or other agreed shipping documents. Any destination-specific documentation requirements should be communicated before order confirmation so that availability, preparation time, and possible costs can be reviewed.
The buyer is responsible for checking local import regulations, customs duties, taxes, installation rules, fuel requirements, electrical standards, and any permits or approvals required at the destination unless otherwise agreed in writing.
Upon receipt, the buyer should inspect the external packaging, product quantity, model, accessories, and visible condition before installation or operation. Any apparent transport damage or package shortage should be noted on the carrier’s delivery record and documented with clear photographs or video.
If an issue is identified, please contact China Loong Generator Co., Ltd. promptly and provide the order number, product model, serial or identification information when available, photographs, video, and a detailed description. Products should not be modified, dismantled, or operated under abnormal conditions before the issue has been reviewed.
Generator sets must be installed and operated by appropriately qualified personnel in accordance with the supplied documentation, local electrical rules, ventilation requirements, exhaust requirements, grounding provisions, fuel-system practices, and site safety procedures.
The buyer should confirm that the installation site is suitable for the generator’s dimensions, weight, airflow, noise conditions, service access, and environmental exposure. Correct fuel, lubricant, coolant, battery, cable sizing, load arrangement, and routine maintenance are important for reliable operation.
When connecting a standby or automatic generator to a building or utility supply, the transfer and protection system should be designed and installed by qualified professionals. Generator specifications and control functions should be verified before connection.
China Loong Generator Co., Ltd. supports customers with order-related documentation, product identification, operation questions, troubleshooting communication, and spare-parts inquiries. The available solution will depend on the product, issue, operating history, order terms, and evidence provided.
For efficient technical review, please provide:
Warranty scope, duration, exclusions, and remedy procedures are governed by the terms confirmed for the specific order. Damage related to incorrect installation, unsuitable operating conditions, unauthorized modification, improper maintenance, normal wear, transport handling, or use outside the confirmed specifications will be assessed according to the relevant circumstances and agreed terms.
Cancellation or modification requests must be submitted in writing and are subject to review based on production status, purchased materials, completed work, customization, packaging, and other costs already incurred. Customized, branded, specially configured, or made-to-order products may not be eligible for cancellation or return once production has started.
Returns must not be sent without prior written authorization and agreed shipping instructions. Claim handling may require photographs, videos, inspection records, return of relevant parts, or other evidence necessary to identify the cause and determine an appropriate solution.
Specifications, commercial terms, delivery instructions, and order changes should be confirmed in writing. If information in a purchase order differs from the accepted quotation, proforma invoice, drawing, or specification sheet, both parties should resolve the difference before production proceeds.
These order terms provide a general purchasing framework. The final quotation, proforma invoice, sales agreement, accepted specifications, and other confirmed order documents will define the requirements and conditions applicable to each transaction with China Loong Generator Co., Ltd.
