We specialize in efficient mixed container loading (FCL), allowing you to combine different product categories, types, and finishes from a single production base into one container shipment. This dramatically simplifies your sourcing and reduces your overall logistics complexity and warehousing costs.
What is your standard lead time for full container load (FCL) orders, and how do you ensure stable delivery during busy periods?
The standard delivery time for full-case orders is consistently 20-35 days after order confirmation, but this varies depending on the product. We ensure our delivery stability by employing a professional ERP manufacturing system, optimizing production planning, and maintaining strategic logistics partnerships. For long-term partners, we also maintain safety stock of commonly used raw materials to ensure stable supply even during peak industry periods. Of course, there are special circumstances (such as war, environmental inspections, holidays, etc.), but we will inform customers of any changes to the delivery date in advance and negotiate amicably with them.
For massive wholesale orders, how do you ensure color and dimensional consistency between different production batches?
Vertical integration is key. We do not rely on third parties to complete critical steps. We smelt aluminum ingots and rods ourselves, mix powders, and complete the anodizing process in a fully vertically integrated production chain. This absolute control, from raw materials to finished products, allows our quality control team to monitor parameters such as anodizing bath time, oven temperature, and powder consistency around the clock to ensure product consistency.

We always put quality and compliance first. We mainly use high-grade aluminum ingots (such as 6063-T5), which are renowned for their excellent hardness, durability and corrosion resistance. The manufacturing processes of all our production bases strictly follow the ISO 9001 quality management system standards. We have our own laboratory and conduct regular hardness tests and salt spray tests. Our products comply with the relevant compliance requirements of large-scale global construction projects.
Does Ghonor comply with international environmental and social responsibility (ESG) standards required by major retailers?
Absolutely. We are committed to sustainable production. We have implemented modern water treatment systems at both bases and adopted energy-saving production methods. We attach great importance to social responsibility and welcome comprehensive third-party factory audits (such as SGS and TUV) to verify our environmental and social compliance and ensure that our supply chain is suitable for major retail chains.
What is your policy and capability for custom mold development and proprietary design protection?
We offer comprehensive OEM/ODM custom mold development services. We sign a comprehensive Non-disclosure Agreement (nda) to ensure that your design is exclusive to your brand. Our engineering team will work closely with you to finalize the drawings, develop molds, and produce prototypes for approval. For bulk wholesale orders, we also offer flexible mold cost amortization solutions.
Logistics & Trade
How does importing from your Vietnam base mitigate anti-dumping duties and trade barrier risks in the USA and Europe?
This is our main strategic advantage. For markets where Chinese-made aluminum products are subject to high anti-dumping duties (such as the United States, Europe, and Mexico), we produce at our modern base in Vietnam. We carry out vertical integration in Vietnam and smelt our own steel ingots. We offer standard-compliant certificates of origin (C/O), enabling you to import high-quality products without incurting punitive tariffs, thereby significantly reducing your import costs and ensuring trade compliance.
Will purchasing from your Vietnam base mean higher costs or more complex logistics compared to importing from China?
Not at all. We have optimized our business in Vietnam to be vertically integrated and cost-effective like our headquarters in China. Although the material and labor costs will be higher than those in China, the overall cost-effectiveness of the Vietnamese factory is higher than that of the Chinese factory due to the reduction in tariff expenditures. In addition, our experienced export team in Vietnam has extensive experience in handling large volumes of global container transportation. From the factory to Haiphong Port, we manage the entire process smoothly to ensure that you receive equally reliable and cost-effective FOB/CIF services from top suppliers.
What specific trade and compliance documentation do you provide to facilitate smooth custom clearance in our destination country?
We provide a complete and compliant set of documents in accordance with the customs requirements of your country. This usually includes: commercial invoices, packing lists, bills of lading (B/L), and highly accurate certificates of origin (for example, standard C/O, Form D, Form E or EUR.1). For goods from our base in Vietnam, we ensure that all documents accurately reflect the origin in Vietnam to meet the eligibility for preferential tax rates or complete tax exemption in the US/EU markets.
How do you ensure the safe packing and securement of heavy and long building materials in containers to minimize damage during international transit?
We adhere to meticulous and professional building materials packaging standards tailored for global retail chains. For aluminium profiles, our processes include each piece of PE protective film, heat shrink film, reinforced main cartons, as well as sturdy, reinforced plywood pallets or crates. We use internal safety devices, straps and airbags inside the container to prevent movement. This ensures that long and heavy goods arrive at your project site in their original and displayable condition.
Which international trade terms (Incoterms) do you commonly operate under (e.g., EXW, FOB, CIF, DDP)?
We can flexibly meet your needs. The trade terms we most frequently use and recommend are FOB (Free on Board) and CIF (Cost, Insurance and Freight) at Chinese or Vietnamese ports. For large supermarket customers or specific project requirements, we can also explore DDP (Tax Paid Delivery) in selected countries. We work with you to select the terms with the lowest risk and cost for your specific operation model.
How do we track our shipment's progress, and what support do you provide regarding global delays or congestion?
We offer proactive tracking and communication. After shipment, we will provide the bill of lading and shipping details for tracking on their official portal website. Our trade service team monitors key goods. In rare events such as global supply chain disruptions or port congestion, we work closely with freight forwarders to find alternative solutions or at least provide timely updates to ensure that you can manage your supermarket's inventory and project expectations.
Do you accept less-than-container-load (LCL) shipments for small wholesalers or project trials?
Yes, we can handle less-than-container load (LCL) transportation as long as our minimum order quantity requirement is met. We know this is crucial for testing new products or managing smaller project requirements. Although the transportation cost per unit of LCL is higher than that of FCL due to the handling and processing fees at LCL ports, we offer this flexibility to support your business expansion towards full container orders.
We are importing into Mexico. Given recent tariff hikes on various Chinese metal goods, how does your Vietnam base provide a duty-safe alternative?
Our Vietnam base is the perfect solution for the Mexican market. By purchasing from our factory in Vietnam, you can avoid the recent increase in specific tariffs imposed by Mexico on Chinese steel and aluminum products. Ghonor has a well-established logistics route from Vietnam to Mexico, which is efficient and reliable. Purchasing from Ghonor Vietnam can ensure that your building materials demand in Mexico maintains stable prices and a secure, tariff compliant supply chain.
Can Australian importers benefit from purchasing from your Vietnam base under the ASEAN-Australia-New Zealand Free Trade Agreement (AANZFTA)?
Absolutely. Vietnamese-origin goods are eligible for preferential duty treatment in Australia under the AANZFTA. We hold standard Form AANZ/Form D preferential Certificates of Origin for our Vietnamese production. When importing from Ghonor Vietnam, you qualify for significant duty reductions or zero preferential tariffs on many of our aluminum building products, making our vertically integrated Vietnam solution a highly competitive option for Australian wholesalers and contractors.
There are concerns about transshipment fraud from some Southeast Asian suppliers. How does Ghonor prove its Vietnam origin is legitimate and not just a transshipment of Chinese goods?
We offer absolute transparency. We are not a simple processing workshop. We carry out vertical integration in Vietnam, melting primary aluminum ingots into alloys and managing the entire life cycle. We welcome you or your designated agent to conduct an on-site factory audit and visit to our factory in Vietnam. We proudly showcased our melting furnaces, modern extrusion production lines, fully automatic anodizing lines, powder coating workshops and precision deep processing machinery. These physical evidences, along with carefully reviewed production records, provide us with legal evidence of origin in Vietnam and more.
Can we expect the same precise dimensional accuracy and complex deep-processing capabilities from your Vietnam factory as we would from your established China facility?
For Ss, each piece sticks protective film, 20pcs wrapped by shrink film, 40pcs per carton for SS304 trims. (Adjust according to the actual situtation) For aluminium: each piece sticks protective film, 20pcs wrapped by shrink film, 200pcs per carton.
How do you ensure that the origin documents (for example, the certificate of origin for Vietnam) are accurate and verifiable to ensure that our customs broker can handle customs clearance without being rejected?
Our documents are issued by official Vietnamese institutions (for example, the Ministry of Industry and Trade). Our documents are regularly reviewed and verified in the official source check to ensure complete accuracy. Moreover, we have already reached cooperation with many customers from Europe, America, Australia and Mexico. When you purchase products from Ghonor Vietnam, our certificate of origin complies with the strict verification requirements of international customs and is accompanied by clear document guarantees.
