China Loong Electrical Instrument Co., Ltd. supplies electrical measuring, testing, calibration, and diagnostic instruments to international B2B customers. Our product range includes digital and analog multimeters, clamp meters, insulation and earth resistance testers, power quality analyzers, oscilloscopes, cable testing instruments, process calibrators, transformer testers, and other electrical inspection equipment. Each order is reviewed according to the selected product, technical requirements, quantity, customization needs, destination, and applicable commercial terms.
Customers may send an inquiry with a product model, product name, application description, or required measurement function. To help us identify a suitable instrument and prepare an accurate quotation, please provide as much of the following information as possible:
Drawings, photographs, specification sheets, reference models, and application notes are helpful when a standard model does not fully describe the requirement.
We review the inquiry to confirm whether a standard product is suitable or whether customization is required. Available customization depends on the product type, order quantity, technical feasibility, component availability, and production requirements.
For customized instruments or private-label orders, the confirmation process may include technical specifications, functional requirements, appearance, labeling, artwork, manual language, accessories, and packaging. Development costs, tooling costs, sample costs, or minimum order requirements may apply and will be stated before the order is confirmed.
If a sample or pre-production unit is needed, its availability, price, preparation time, and shipping arrangement will be confirmed separately. Approval of a sample does not replace the need to confirm the final written order specifications.
Our quotation is prepared according to the confirmed model, specifications, quantity, customization, accessories, packaging, delivery destination, and trade terms. The quotation may include the following information:
Prices may change if the specification, quantity, packaging, delivery method, or other order details are revised. Freight, insurance, import duties, taxes, customs clearance charges, bank fees, and destination handling costs are included only when expressly stated in the quotation.
An order is considered confirmed after both parties have agreed on the product and commercial details and the required order documents have been accepted. Depending on the transaction, the confirmation documents may include a purchase order, proforma invoice, specification sheet, artwork file, packing requirements, or other written approvals.
Before confirming the order, customers should carefully check:
Any detail not shown in the confirmed order documents will be handled according to the applicable standard product configuration or subject to further written confirmation.
Payment arrangements are confirmed according to the order value, product type, customization level, transaction history, and other commercial considerations. The accepted payment method, payment schedule, currency, bank information, and applicable charges will be stated in the proforma invoice or sales agreement.
Production, customization, or shipment may begin only after the required payment stage has been completed and the funds have been verified. Customers should use only the bank details shown on our formally issued documents. If any request is received to change payment details, please verify it directly with China Loong Electrical Instrument Co., Ltd. before making payment.
Bank charges and intermediary bank fees are handled according to the confirmed payment terms. Delays in payment or payment verification may affect material preparation, production scheduling, or shipment timing.
Production or order preparation is arranged after the technical requirements, commercial documents, artwork, and applicable payment conditions have been confirmed. The estimated schedule depends on the model, quantity, customization, material availability, inspection requirements, and production workload.
For customized orders, we may request approval of labels, artwork, product information, packaging layouts, or samples before proceeding. Customers should provide complete feedback within the agreed review period to avoid unnecessary scheduling changes.
Products are checked according to the confirmed order requirements and the applicable inspection process for the relevant instrument. Depending on the order, inspection may cover appearance, configuration, basic operation, measurement functions, included accessories, labels, quantity, and packaging. If additional inspection, testing records, calibration documents, or third-party inspection arrangements are required, these must be discussed before order confirmation and may involve additional time or cost.
Production updates, photographs, or pre-shipment information may be provided when agreed for the order. Such materials are intended to support order communication and do not replace the final specifications or agreed inspection criteria.
Requests to change the model, quantity, specification, logo, packaging, shipping address, or delivery method should be submitted in writing as early as possible. We will review whether the change can be accepted based on the current order status.
Changes requested after materials have been purchased, customization has begun, or production has started may affect the price and delivery schedule. Related material, labor, tooling, packaging, or administrative costs may also apply. Cancellation conditions are subject to the confirmed order documents and the actual progress of the order.
Products are packed according to the product characteristics, selected accessories, order quantity, transportation method, and agreed packaging requirements. Standard export-oriented packaging or customized packaging may be arranged subject to confirmation.
Delivery may be arranged by express courier, air freight, sea freight, rail, or another agreed logistics method. The available shipping method depends on the shipment size, weight, destination, required timing, product characteristics, and local transportation conditions.
The applicable Incoterm, freight responsibility, insurance arrangement, estimated dispatch date, and required shipping documents will be confirmed for each order. Transit times provided by carriers are estimates and may be affected by customs procedures, transportation capacity, weather, holidays, destination regulations, or other circumstances outside the seller’s direct control.
Customers are responsible for providing accurate consignee information and reviewing local import requirements before shipment. Import licenses, duties, taxes, customs clearance, and destination charges are handled according to the agreed trade terms. Any special document or labeling requirement should be communicated before order confirmation.
Upon delivery, customers should check the outer packaging, carton quantity, product model, quantity, accessories, and visible condition. If there is apparent transportation damage, the condition should be recorded with the carrier at the time of receipt whenever possible.
Any discrepancy or product issue should be reported promptly with the order number, product model, serial number where applicable, a clear description of the issue, and supporting photographs or videos. Please retain the product, accessories, labels, and original packaging while the issue is being reviewed.
China Loong Electrical Instrument Co., Ltd. provides order-related communication and technical assistance for supplied products.

We will review the information and recommend appropriate next steps, which may include operating guidance, additional testing, replacement parts, return inspection, repair, or another solution depending on the product condition and the confirmed order terms. Products should not be returned without prior authorization and return instructions.
Warranty scope, service conditions, return arrangements, and related costs are handled according to the applicable product documentation and confirmed sales terms. Damage caused by incorrect wiring, operation outside the specified range, unauthorized modification, unsuitable storage, improper handling, or normal wear may require separate evaluation.
For repeat orders, please provide the previous order number, product model, and any requested changes. Components, appearance, packaging, or specifications should not be assumed to be identical unless they are reconfirmed in the new order documents.
