Can a Sight Letter of Credit Work for a Large Aluminium Casement Window Order?

For a high-volume aluminium casement window order, a sight letter of credit can be an effective payment method when the buyer wants bank-controlled document review before funds are released. Xinhe Aluminium accepts sight L/C arrangements for aluminium profiles and supplies aluminium casement windows, doors, and architectural systems. Profile orders have a 3-ton minimum order quantity, an estimated 15–20-day delivery period, and inspection support throughout production.

Why a Sight L/C May Suit the Shipment

A sight L/C connects payment to the presentation of documents agreed by the buyer and seller. For a large shipment, these documents may include the commercial invoice, packing list, bill of lading, inspection records, product specifications, and other loading documents. This arrangement gives the buyer a defined documentary control process while allowing the supplier to receive payment once the conditions are met.

Sea freight is the listed shipping option for Xinhe Aluminium. It offers a lower unit freight cost, substantial loading capacity, and practical handling for long aluminium profiles and assembled window components. The L/C should therefore describe the product scope, packaging method, quantities, shipment schedule, and required shipping documents in precise terms.

Confirm the Product Scope Before Opening the L/C

The payment arrangement should reflect whether the order is for extruded aluminium profiles or complete aluminium windows and doors. The stated T/T terms are different for these two categories. Aluminium profiles require 30% D/P before production and 70% before loading, while aluminium windows and doors require 50% D/P before production and the remaining balance before loading. Buyers using an L/C should confirm the applicable commercial terms before the bank instrument is issued.

Technical specifications should also be finalized in advance. The architecture profile range supports 6063, 6060, 6061, 6463, 6005, 6082, and 6106 aluminium alloys, with T5 and T6 tempers available. Depending on the project, the order may cover standard casement window profiles, narrow-frame systems, large-section curtain wall profiles, or customized cross-sections.

Production, Inspection, and Project Capacity

For profile purchases, Xinhe Aluminium states a 3-ton MOQ and a 15–20-day delivery time. Its quality assurance process includes complete production-line inspection, laboratory sampling and testing, and inspection of incoming raw materials. These records can be included among the documents required under the L/C if the parties agree on the format and issuing authority before production begins.

The company’s project history includes large building and hospitality orders. A hotel project in Malaysia used approximately 700 tons of aluminium products, while a building project in the Philippines involved 830 tons. The Philippines project also included custom die development for special sections, such as narrow-frame and large-section curtain wall profiles. These examples show why a large casement window shipment may require coordinated planning for tooling, extrusion, inspection, packing, and vessel loading.

The listed credentials include SIRIM certificate PC003807 for aluminium and aluminium alloy extruded shapes used in windows and sliding doors in Malaysia. Xinhe Aluminium also holds Quality Management System Certificate 00225Q24002R3M under GB/T 19001-2016/ISO 9001:2015.

Payment and Shipping Comparison

Recommended L/C Preparation Checklist

Before issuing the letter of credit, the buyer and supplier should agree on the exact product description, alloy and temper, dimensions, surface finish, quantities, tolerances, packaging, inspection documents, shipment deadline, partial-shipment rules, and loading port. The commercial invoice and packing list should use descriptions that match the purchase contract and the L/C to reduce the risk of documentary discrepancies.

For a project involving complete casement windows, the parties should additionally define hardware, glass, assembly requirements, protection materials, and container-loading arrangements. For profile-only orders, the focus should be on bundles, lengths, surface protection, customized dies, and the handling of long extrusions during sea transport.

Frequently Asked Questions

No. The stated terms are 30% D/P before manufacture and 70% before loading for aluminium profiles. Aluminium windows and doors use a stated 50% D/P before manufacture, with the balance due before loading. The final terms should be confirmed for the specific order.

What inspection support is available for a large shipment?

Inspection includes 100% production-line inspection, laboratory sampling and testing, and incoming raw-material inspection. The related documents can be coordinated with the L/C requirements before manufacture.

Why is sea freight suitable for these products?

Sea freight combines lower unit freight costs with large cargo capacity. It is particularly suitable for long aluminium profiles and sizeable consignments of window and door components.

Conclusion

A sight letter of credit is a practical option for a large aluminium casement window shipment when payment must depend on clearly defined and bank-checked documents. The buyer should first distinguish between aluminium profiles and complete windows and doors, then align the L/C with technical specifications, inspection evidence, packaging, and sea-freight requirements. Xinhe Aluminium supports building, hotel, residential, office, curtain wall, and other architectural applications, with experience in both standard and customized aluminium profile projects.
