1. About package
1.1 In our daily production operations, we always maintain a rigorous and scientific attitude towards the product packaging process. When it comes to selecting materials for the inner packaging of products, we typically use plastic films, plastic bags, or plastic trays. Thanks to their excellent sealing properties and corrosion resistance, these materials can effectively protect products and perform the functions of moisture prevention and rust prevention remarkably well. Especially for those fastener products with high manufacturing precision or those that are relatively fragile and vulnerable, we will additionally use cushioning materials with excellent shock absorption performance, such as foam plastics and sponges, to further enhance the protection. In this way, we can avoid product damage caused by various collisions and jolts during transportation, ensuring the integrity and quality of products to the greatest extent. Regarding the outer packaging, we usually choose corrugated cardboard boxes, wooden cases, or plywood cases. Corrugated cardboard boxes are lightweight and cost-effective, making them suitable for fasteners with relatively light weights. Wooden cases and plywood cases have high strength, which not only allows them to bear heavier loads but also enables them to meet the fumigation requirements for export packaging, making them ideal for heavy-duty or vulnerable fasteners.
1.2 In addition, we attach great importance to the personalized needs of each customer and are committed to providing customized packaging services. If customers have unique design requirements for the color, pattern, and size of the packaging, or if they expect to print exclusive brand logos on the packaging to enhance their brand image, we will go all out, mobilize various resources of the company, and make every effort to meet each special requirement of the customers. We strive to create unique packaging solutions for customers that are in line with their brand concepts and market positioning.
2.About payment
Our company uniformly adopts T/T (Telegraphic Transfer) as the payment method. For regular orders, a 30% advance payment is required at the time of placing the order to initiate the order process. The remaining 70% balance must be fully settled before the goods are loaded onto the vehicle to ensure a seamless connection between the payment transfer and the goods transportation process.
In the case of customized products, considering the particularity of their production, the advance payment proportion is adjusted to 30% - 50%, which needs to be paid upon finalizing the customized details and signing the contract. The remaining balance is also required to be paid off before the goods are loaded. Only when the balance is cleared can the goods be guaranteed to be delivered to your designated location on time and smoothly, avoiding any possible delays or disputes.
3.About Delivery & shipment
For in-stock products, with the support of our efficient logistics distribution system and internal coordination mechanism, we promise to complete the delivery within 10 days, enabling you to obtain the desired goods promptly. As for customized products, since they need to be produced according to specific specifications and requirements, involving multiple processes such as design confirmation, raw material procurement, and production, we will generally complete the delivery within one month, ensuring that you can receive the customized products that meet your needs as scheduled.
