China Loong Water Filter Co., Ltd. supplies water filtration and treatment products for international distributors, wholesalers, project contractors, private-label customers, and other business buyers. Our product range includes reverse osmosis systems, whole-house and under-sink filters, commercial filtration systems, water dispensers, filter cartridges, membrane elements, water purifier parts, water treatment machinery, cable ties, and related accessories. The following guide explains our standard ordering process. Specific commercial terms are subject to confirmation according to the product, quantity, customization requirements, and destination.
Please send us an inquiry with as much information as possible so that we can recommend a suitable product and prepare an accurate quotation. You may provide a product model, specification sheet, reference image, drawing, or description of the intended application.
If you are unsure which model is suitable, our team can review your application details and discuss available options. Product suitability depends on actual operating conditions and the specifications confirmed for the order.
Samples may be arranged for product evaluation when applicable. Sample availability, charges, customization options, preparation time, and shipping costs depend on the selected product and current requirements. Customized samples may require confirmation of artwork, specifications, tooling, or packaging before preparation begins.
Sample approval does not automatically confirm a bulk order. Final bulk-order details, including quantity, price, packaging, production schedule, and shipment terms, must be confirmed separately in the relevant order documents.
China Loong Water Filter Co., Ltd. can discuss product configuration and private-label requirements according to the selected item. Customization may include branding, color, filtration configuration, filter cartridge combinations, connection types, electrical specifications, packaging, manuals, labels, and accessories, depending on product feasibility.
Our quotation will normally be prepared based on the confirmed specifications, order quantity, customization level, packaging method, delivery term, and destination information. The quotation may include the following details where applicable:
Prices may change if specifications, quantities, raw material requirements, exchange conditions, packaging, or shipping arrangements are revised. Any change should be confirmed in writing before the order proceeds.
An order is considered ready for processing after both parties confirm the essential commercial and technical details. Depending on the order, confirmation may be recorded through a quotation, proforma invoice, purchase order, sales contract, specification sheet, artwork approval, or other written document.
Please review the following information carefully before approval:
The buyer is responsible for checking approved specifications, artwork, spelling, barcodes, model numbers, electrical information, and shipping details. Changes requested after approval or after production has started may affect cost and schedule and will require separate confirmation.
Available payment methods and payment timing are determined according to the order value, product type, customization requirements, transaction history, and other commercial considerations. The applicable arrangement will be stated in the quotation, proforma invoice, sales contract, or other confirmed order document.
Please make payment only to the company account specified in our verified commercial documents. If you receive a request to change bank details, contact our authorized representative through a previously verified communication channel before transferring funds. Bank charges and transaction fees will be handled according to the payment terms confirmed for the order.
Production, customization, or shipment will be scheduled after the required payment and order information have been received, unless a different arrangement has been agreed in writing.
Production is arranged according to the approved order details. For customized products, we may request confirmation of drawings, artwork, labels, packaging layouts, samples, or key specifications before proceeding with the relevant production stage.
We will communicate material questions, specification issues, or necessary adjustments when they arise. Production schedules depend on product complexity, order quantity, component availability, customization, approval timing, and other order-specific factors. Any schedule provided before final confirmation is an estimate rather than a fixed commitment.
If the buyer needs a design or order change, the request should be submitted in writing as early as possible. We will evaluate whether the change is feasible and advise of any effect on price, materials, production progress, or delivery timing.
Products are checked against the confirmed order requirements using inspection procedures appropriate to the product type. Checks may cover appearance, dimensions, assembly, quantity, packaging, labeling, accessories, and relevant functional items. The exact inspection scope depends on the product and agreed specifications.
When requested and feasible, production or packing photographs may be provided for communication purposes. If the buyer requires third-party inspection, special testing, or specific documentation, these requirements must be stated before order confirmation. Related costs, procedures, acceptance criteria, and scheduling implications are subject to agreement.
Standard or customized packaging can be arranged depending on the product and order requirements. Water filter systems, replacement cartridges, membrane elements, dispensers, treatment equipment, parts, and accessories may require different protective packing methods.
Please advise us in advance if the order requires private-label cartons, color boxes, neutral packaging, barcode labels, shipping marks, palletization, multilingual manuals, special accessory placement, or destination-specific labeling. Customized packaging is subject to artwork approval, material availability, quantity requirements, and additional charges where applicable.
Packaging dimensions and weights may be estimated during quotation and confirmed after the final product configuration and packing method are established.
Orders may be shipped by express courier, air freight, sea freight, rail, or another agreed method, depending on the shipment size, destination, urgency, product characteristics, and buyer preference. The applicable trade term and shipping responsibility will be specified in the confirmed order documents.
Freight charges and transit times are subject to carrier schedules, routing, fuel costs, customs procedures, port conditions, peak-season demand, and other factors outside the manufacturer’s direct control. Estimated delivery information is provided for planning purposes and may change.
The buyer should provide complete and accurate consignee details, contact information, tax or registration information where required, and any import instructions before shipment. Unless otherwise agreed, the buyer is responsible for understanding local import regulations, customs duties, taxes, permits, and product compliance obligations in the destination market.
Shipping documents will be prepared according to the agreed transaction and available order information. Requests for certificates of origin, special invoice formats, packing details, or other documents should be communicated before shipment and are subject to availability and confirmation.
Upon delivery, the buyer should promptly check the number of packages and inspect the outer cartons for visible damage. If damage, shortage, or delivery irregularity is identified, record the issue on the carrier’s receipt where possible and retain the packaging, labels, photographs, and relevant transport documents.
The buyer should inspect the products within a reasonable period after receipt and compare them with the confirmed order specifications. Products should be stored, installed, flushed, operated, and maintained according to the applicable instructions and intended use. Filter performance and service life can vary with water quality, pressure, usage volume, operating conditions, and maintenance practices.
If you identify a product or order issue, contact China Loong Water Filter Co., Ltd. with the order number, product model, quantity affected, and a clear description of the problem. Photographs, videos, packaging labels, installation details, water conditions, and test information may be requested to support evaluation.
We will review the information and discuss an appropriate response based on the confirmed specifications, inspection findings, product use, order terms, and available evidence. The handling method may vary according to the nature and cause of the issue. Products should not be returned, discarded, repaired, or modified without prior written communication, as this may affect verification and resolution.
For repeat orders, please reference the previous order number and confirm whether the specifications, packaging, artwork, quantity, and destination remain unchanged. Do not assume that all details will automatically remain the same, as components, packaging materials, logistics conditions, and commercial terms may require reconfirmation.
For ongoing distribution, private-label programs, replacement filter planning, or project supply, buyers are encouraged to share estimated purchasing schedules in advance. This supports better coordination of product selection, materials, packaging, and shipment planning without creating a fixed purchase or delivery commitment unless separately agreed in writing.
To begin, send us the product name or reference image, required specifications, estimated quantity, customization details, and delivery destination. China Loong Water Filter Co., Ltd. will review the request, clarify necessary technical and commercial information, and provide the corresponding quotation or order proposal for your confirmation.
