FAQ
  • Minimum Order Quantity (MOQ)？
    We have flexible MOQ requirements to support your procurement needs. For most regular single products, the minimum order quantity is 50 pieces. For small hardware products such as barbecue grills, air conditioner condensate drain pans and various mounting brackets, the MOQ is 100 pieces. We can adjust the MOQ appropriately according to your actual order demand to meet your procurement plan.
  • Standard & Customized Product Quotation
    We are professional in customizing various hardware sheet metal products and plastic parts. We will prepare and send you the detailed official quotation sheet within 3 working days. To ensure the accuracy of the quotation, please kindly inform us of the specific product models, specifications and customization requirements you need. We will provide you with the most reasonable and targeted price based on your detailed demands.
  • Packaging Solutions & Customization Service
    Our standard packaging adopts foam inner protection, carton outer packaging and outer plastic film winding, which can effectively protect products from damage during long-distance transportation. Meanwhile, we fully support personalized packaging customization. We can adjust the packaging specification, material and appearance according to your exclusive requirements to meet your supermarket sales and brand display needs.
  • Production Cycle & Delivery Time to Munich
    We have mature and efficient production capacity, with a daily output of 1,500 pieces for single products. Under conventional order quantities and production requirements, the total production cycle will not exceed 3 months. To support your urgent delivery demand, we can arrange overtime production, and the production period can be shortened to more than 1 month at the fastest.In terms of logistics, we adopt the FOB Ningbo cooperation term for all export businesses, which is the most secure and mainstream trade term. The sea freight from Ningbo Port to Munich, Germany takes about 50-60 days. We provide flexible logistics cooperation solutions: if you do not have a cooperative forwarder, we can recommend reliable logistics resources for you; if you need one-stop full shipping service, we can arrange the whole process for you. It is worth mentioning that if you confirm cooperation under FOB terms, the larger your order quantity, the more substantial price discounts and preferential policies we can offer. Meanwhile, we will provide you with more free value-added services accordingly.
  • Value-added Services & Compliance Support
    We provide free product customization and label pasting services for all cooperative customers. We support product production with multiple materials including stainless steel, galvanized sheet and aluminum sheet for your selection. Among them, stainless steel features strong corrosion resistance and durability with a slightly higher price; galvanized sheet has the highest cost performance and is the most cost-effective choice; aluminum sheet is low in price but poor in corrosion resistance, so we do not recommend it for long-term use.In terms of export compliance, we have complete product qualification certificates. We can fully cooperate with you in providing all official documents and materials required for German import customs clearance, and assist you in solving all compliance-related problems to ensure smooth customs clearance of goods.
  • Product Catalog & Company Strength
    Most of our previous orders are customized according to customers’ specific requirements, so we do not have a universal fixed price list. Upon receiving your inquiry, we will promptly send our official product catalog and price list of regular hot‑selling items for your reference. After you confirm target products and place a definite purchase order, we will prepare a precise, customized quotation for you without delay. We will immediately issue the production schedule, carry out manufacturing strictly in accordance with the schedule, and fully guarantee on‑time delivery.
