Importing doors and windows from China does not need to be complicated.You do not need to understand every technical detail before contacting a supplier.
For most projects, you can start with what you already have: dimensions, quantities, drawings, reference photos or a door and window schedule. From there, the product configuration can be discussed and confirmed step by step.
What matters more is knowing what you are buying and what you are comparing. Two windows that look similar can have very different specifications, prices and performance.
This guide covers the main things worth considering before you place an order.
1. Why Can Door and Window Prices Be So Different?
Many buyers start with the same question:
“How much is it per square meter?”
That is a reasonable place to start. But for doors and windows, the price per square meter only tells part of the story.
Two windows can have the same dimensions and look very similar, but the price may be quite different because of the profile, glass, opening style and hardware.
For example, glass thickness affects the price. Double or triple glazing, Low-E glass and argon filling also make a difference. A basic sliding window and a thermal-break casement window are not really comparable products, even if they are the same size. Hardware quality can create another noticeable difference.
So when comparing quotations, do not look only at the final number. Check what configuration is included in that price.
This makes it easier to tell whether one quotation really offers better value or simply represents a different product.
2. Know What You Need and Set a Rough Budget
Before asking for a final quotation, it helps to have a general idea of your project.
Is it a budget-focused project, a standard residential project or a higher-end development?
What matters most to you: price, insulation, appearance, durability, or a balance of several factors?
And roughly how much have you planned to spend on the doors and windows?
You do not need to decide every technical specification yourself. A clear project position and approximate budget already give the supplier a useful direction for recommending a suitable configuration.
If you are not sure which level to choose, comparing a standard option and an upgraded option can be more useful than simply asking several suppliers for their lowest price.
You can then see where the additional cost comes from and decide whether the upgrade is worthwhile for your project.
3.What Do You Need to Quote Doors and Windows from China?
You do not need to prepare a complicated technical package just to start an inquiry.
For most projects, the following information is enough to begin:
- Dimensions
- Quantity
- Door or window type
- Preferred material
- Opening style, if known
- Drawings or reference photos, if available
- Project location
For a larger construction project, a door and window schedule or opening schedule is especially useful. It allows different sizes, quantities and opening types to be organized clearly.
If you already have architectural drawings, send them as well.
If some details are still undecided, that does not necessarily prevent an initial discussion or quotation. Start with the information you already have, and the remaining specifications can be confirmed as the product configuration develops.
4. Choose the Right Door, Window, Glass and Hardware
Once the basic project information is clear, the next step is choosing a suitable configuration.
For windows, common options include aluminum and uPVC systems, with styles such as casement, sliding, tilt and turn, awning and fixed windows.
Doors may include aluminum doors, steel entrance doors, wooden doors, sliding doors and fire-rated doors.
There is no single configuration that is best for every project. Climate, building type, appearance, required performance and budget all influence the choice.
Glass is another important part of the configuration. If your project already specifies the glass, simply send the specification to the supplier, for example:
5 mm + 12A + 5 mm insulated glass
Depending on the project, other options may include Low-E glass, argon filling, tempered glass, laminated glass or triple glazing.
The same applies to hardware. Some projects specify a particular brand, while others focus more on function, durability and budget.
The goal is not to choose the most expensive configuration, but to choose one that suits the actual project.
5. What About Fire Doors?
Fire-rated doors need a little more information than ordinary doors.
Besides dimensions and quantity, the most important points are the required fire rating and applicable standard or certification requirement.
Depending on the project, other details may include:
- Single or double leaf
- Opening direction
- Vision panel
- Panic bar
- Door closer
- Lock and handle
- Smoke or intumescent seals
If you already have a fire door schedule or project specification, the easiest approach is to send it to the supplier for review.
A “60-minute” or “120-minute” fire rating alone does not necessarily indicate which standard the project needs to follow. Confirming the applicable requirement before production helps avoid comparing products that appear similar but are based on different standards.
6. Check Sizes, Colors and Samples Before Production
For simple replacement orders, you may already know the required finished size.
For construction projects, however, the wall opening and the final manufacturing size of the door or window may not be exactly the same. Frame dimensions, installation clearance and wall construction all need to work together.
You do not need to calculate every detail yourself. If architectural drawings, rough opening dimensions or wall details are available, provide them so the relevant dimensions can be checked before production.
For larger projects, shop drawings are useful for confirming dimensions, opening directions and key installation details in one place.
Appearance should also be confirmed before mass production.
RAL color references are commonly used for aluminum and steel products. If the project is particularly sensitive to color, finish, glass appearance or hardware, physical samples can also be used for confirmation.
For larger orders, a product sample may help you check the finish, profile, hardware and general workmanship before moving ahead with the full quantity.
Not every project needs a physical sample. It depends on the order size, level of customization and how important the visual details are.
7. Packaging, Shipping and Freight Cost
Doors and windows need proper protection during international transportation, especially glass and finished surfaces.
Depending on the product, export packaging may include protective film, corner protection, foam, reinforced cartons, pallets, wooden frames or wooden cases.
For project orders with many different sizes, package numbers can also correspond with the door and window schedule. This makes the products easier to identify and distribute after arrival.
When importing doors and windows from China, another cost worth considering early is international freight.
Sometimes the product price looks attractive, but the shipping cost comes as a surprise. Doors and windows are relatively large products, so international transportation can represent a significant part of the total landed cost.
Under similar shipping conditions, freight costs are generally influenced more by shipment volume, container utilization, shipping route and destination than simply by which Chinese supplier you purchase from.
This is also why purchase quantity matters.
For a small order, the freight cost allocated to each door or window can be relatively high. As the quantity increases and container space is used more efficiently, the transportation cost can be spread across more products.
So when planning an import, it is better to consider product cost and transportation cost together, rather than judging the purchase only by the factory price.
Depending on your logistics arrangement, quotations can also be prepared under different delivery terms such as EXW, FOB, CIF or DDP.
8. Check Local Requirements Before Ordering
Building requirements vary between countries and projects.
Depending on the destination and building type, doors and windows may need to meet requirements related to thermal performance, wind resistance, safety glazing, water and air performance, fire resistance or other local standards.
This does not mean you need to study an entire building code before contacting a Chinese supplier.
If your architect, contractor or project specification already states the required performance or certification, provide that information during the quotation process. The proposed product configuration and available documentation can then be checked against those requirements.
This is particularly important for fire doors and projects with mandatory performance or certification requirements.
For international projects, doors and windows are also commonly supplied from China and installed by local contractors. Product drawings and relevant installation information can be coordinated according to the agreed supply scope, while site conditions and local installation should be considered by the project team.
9. Keep the Purchasing Process Simple
In practice, importing doors and windows from China can follow a fairly straightforward process:
Project information → Configuration → Quotation → Drawing or sample confirmation → Production → Inspection and packing → Shipment
You do not need to have every technical answer at the beginning.
Start with the information you already have, understand what is included in the quotation, and make sure the important details are confirmed before production.
For larger projects, it is also useful to look at the door and window package as a whole rather than comparing each item only by its lowest unit price. The right configuration, clear drawings, consistent finishes, organized packaging and reasonable container utilization all affect the final result and overall purchasing cost.For a broader overview of project purchasing, read our guide to Building Material Sourcing from China.

For an initial quotation, your existing drawings, schedules, quantities and project requirements are usually enough to get started.
FAQ
What information is needed to order doors and windows from China?
For an initial quotation, start with the dimensions, quantities, window type and project location. If you already have drawings, an opening schedule or reference photos, send them as well.
Glass, hardware, colors and other details can then be confirmed as the quotation and product configuration are developed.
Can Chinese windows meet local building codes?
Doors and windows can be produced for different performance requirements, but compliance depends on the specific product configuration, applicable standard, testing and documentation required by the project.
If your project has specific performance or certification requirements, provide them before the final product configuration is confirmed.
How are doors and windows packed for export?
Packaging depends on the product, dimensions and shipping method. Common protection includes protective film, corner protection, foam, reinforced cartons, pallets, wooden frames and wooden cases.
For project orders, packages can also be numbered according to the door and window schedule, making the products easier to identify after arrival.
Is it worth importing a small quantity of doors and windows from China?
It can be, especially for customized products or specifications that are difficult to source locally. However, international freight should be considered together with the product price.
For very small orders, freight may represent a relatively high cost per unit. Larger orders generally make better use of container space and allow the transportation cost to be spread across more products.
