Our product range includes smoke, combustible gas, carbon monoxide, toxic gas, water leakage, temperature and humidity, intrusion, emergency call, pressure, and equipment condition alarms. The following ordering process is designed to help international buyers confirm technical requirements, customization, payment, production, packing, and delivery clearly before shipment.
Please send us an inquiry with the product type, intended application, required quantity, and destination country or region. To help us recommend a suitable model and prepare an accurate quotation, please provide as much of the following information as possible:
Reference photographs, drawings, specification sheets, or samples are helpful when the inquiry involves a replacement product, a special installation, or integration with an existing alarm system.
After receiving the inquiry, China Loong Alarm Co., Ltd. will review the application and product requirements. We may contact the buyer to clarify the detection principle, alarm output, operating voltage, communication interface, installation conditions, or other technical details before recommending a product.
Customization may include product appearance, color, logo, label, packaging, alarm settings, wiring, connectors, communication functions, accessories, and documentation, depending on the selected model and technical feasibility. Any customization request must be evaluated and confirmed before the order is placed.
Quotations are prepared according to the confirmed model, specifications, quantity, customization, packaging, testing requirements, and delivery terms. Unless otherwise stated, a quotation does not include unconfirmed changes, destination import duties, local taxes, or additional third-party charges. Quotation validity and applicable trade terms will be stated in the commercial documents.
Buyers may request samples for functional evaluation, installation testing, or market assessment. Sample availability, sample cost, customization options, payment, and transportation arrangements are subject to confirmation.
Buyers are responsible for checking whether a sample meets the intended application and local requirements before approving a bulk order. A sample or pre-production confirmation may be recommended for customized products, printed packaging, special labels, networked alarm functions, or non-standard technical configurations.
Approval of a sample does not automatically include later modifications. Any change requested after sample approval may affect the price, production schedule, tooling, packaging, or minimum order requirements.
An order is considered ready for processing after both parties have confirmed the applicable commercial and technical details. The order confirmation may include:
The buyer should carefully review the quotation, specification sheet, artwork, packing details, and pro forma invoice before approval. Any discrepancy should be reported promptly. Purchase orders are accepted based on the specifications and commercial terms confirmed by both parties.
For customized branding or packaging, the buyer should provide clear logo files, text, product information, barcodes, warning statements, and other required content in an appropriate format. The buyer is responsible for ensuring that supplied trademarks, artwork, instructions, and claims may be legally used in the target market.
We may provide an artwork layout or digital proof for approval before production. The buyer should check spelling, model numbers, technical information, colors, barcode data, carton marks, and language content carefully. Production will follow the final approved files, subject to reasonable manufacturing tolerances.
Payment terms are confirmed according to the order value, product type, customization level, transaction history, and agreed trade conditions. The accepted payment method, currency, payment schedule, bank information, and any related charges will be specified in the pro forma invoice or other agreed order document.
Production, material preparation, customization, or shipment may begin only after the required payment or payment confirmation has been received. Buyers should remit funds only to the bank account stated in official documents issued by China Loong Alarm Co., Ltd. Any request to change payment information should be verified with our authorized contact before payment.
Bank charges and intermediary bank fees are handled according to the agreed payment terms. Orders delayed by incomplete payment, payment verification, or missing buyer information may require a revised production or shipping schedule.
Production is arranged after the order requirements and applicable payment conditions have been confirmed. The estimated lead time depends on the product model, quantity, material availability, customization, testing, packaging, and current production schedule.
For customized orders, production updates or reference photographs may be provided when agreed and practical. Such updates support communication but do not replace any formally agreed inspection procedure.
Requests to change specifications, quantities, artwork, packaging, or delivery instructions after order confirmation must be submitted in writing. China Loong Alarm Co., Ltd. will evaluate whether the requested change is feasible. Approved changes may affect price, material usage, production time, testing, or delivery arrangements. Materials or finished products already produced according to the original approval may be charged as part of the order.
Products are checked according to the confirmed specifications and applicable internal inspection procedures. Depending on the product, checks may cover appearance, assembly, power supply, sensing or alarm response, audible and visual output, communication functions, labeling, accessories, and packaging.
If the buyer requires a specific inspection standard, test method, inspection report, third-party inspection, or pre-shipment inspection, this requirement should be stated before the order is confirmed. Related feasibility, costs, sample quantities, timing, and acceptance criteria must be agreed separately.
The buyer or an authorized inspection company may request a pre-shipment inspection by prior arrangement. If an inspection identifies a difference from the confirmed order requirements, both parties will review the findings and agree on appropriate corrective action before shipment.
Standard or customized packing will be used according to the confirmed order. Packing may include individual product boxes, inner cartons, export cartons, protective materials, labels, manuals, accessories, and shipping marks as applicable. Special packing requirements should be provided during the quotation stage.
Delivery may be arranged by express courier, air freight, sea freight, rail, or another suitable method depending on shipment size, urgency, destination, and buyer preference. Freight cost, insurance, export arrangements, and delivery responsibilities are determined by the agreed trade terms.
Estimated shipping dates and transit times are provided for planning purposes and remain subject to production completion, carrier schedules, customs procedures, weather, destination conditions, and other circumstances outside the reasonable control of the supplier. Shipping documents will be prepared according to the agreed order and transportation arrangement.
The buyer should confirm the technical, labeling, documentation, registration, installation, and import requirements that apply in the destination market before placing an order. Requirements may vary according to product type, intended use, country, industry, and distribution channel.
Please inform us during the inquiry stage if specific documentation, testing, markings, packaging language, or product configuration is required. China Loong Alarm Co., Ltd. will review the request and confirm what can be supplied for the selected product and order. No compliance requirement should be considered included unless it is identified and confirmed in the order documents.
Upon delivery, the buyer should inspect the outer cartons, quantities, product models, labels, accessories, and visible condition of the goods. Any apparent transport damage, carton shortage, or delivery discrepancy should be recorded with the carrier where applicable.
If a product issue or order discrepancy is found, please contact us promptly and provide the order number, product model, quantity affected, batch or label information, photographs, videos, test conditions, and a clear description of the issue. Products should be stored, installed, powered, and used according to the applicable instructions while the matter is being reviewed.
