How to Import Aluminum Windows from China: Complete Guide for US & European Buyers
Aluminum windows are one of the most globally sourced building products – China produces a large share of the world’s aluminum window and door systems. For distributors, builders and project buyers, importing directly from a Chinese manufacturer can significantly reduce cost. But it also comes with risks if you don’t know the process.
This guide walks through the entire import process, step by step.
Why Import Aluminum Windows from China
- Cost advantage – manufacturing cost is typically 30-50% lower than domestic production in the US or Europe.
- Mature supply chain – world-class aluminum extrusion, glass, and hardware ecosystems.
- Custom production – most Chinese factories build to client drawings (OEM/ODM).
- Certification capability – leading factories hold CE, NFRC, and AAMA/WDMA certifications.
The key is choosing the right factory and managing the process professionally.
Step 1: Find and Vet Suppliers
Don’t pick a supplier from price alone. Vet them on:
| What to check | Why it matters |
|---|---|
| Factory vs trading company | Factories give better control and price |
| Years in business | Stability and experience |
| Export markets | US/Europe experience = knows your codes |
| Certifications | CE, NFRC, AAMA/WDMA (verify authenticity) |
| Product range | Can they supply your full project? |
| References | Ask for 2-3 past projects in your market |
Verification tip: Ask for certification numbers and check them in the official databases (NFRC, AAMA, UL). A supplier with valid approvals will share them without hesitation.
Step 2: Request Quotations (RFQ)
Send a clear RFQ with:
- Product type (casement, sliding, door, etc.)
- Drawings or dimensions
- Quantity per size
- Glass specification
- Surface finish
- Destination port
- Required certifications
Don’t accept a one-line price. A professional factory will ask clarifying questions and provide a structured quotation.
Step 3: Samples and Drawings
- Request shop drawings for approval before production.
- Order a sample if the project is large or the supplier is new.
- Confirm: profile, glass, hardware, finish, and packing.
Sample cost is usually credited to your first bulk order.
Step 4: Understand MOQ and Lead Time
| Item | Typical Range |
|---|---|
| MOQ | 20-50 sets per size/project (flexible for trials) |
| Lead time | 15-30 days after drawing approval |
| Sample lead time | 7-15 days |
Clarify both before committing – especially if you have a project deadline.
Step 5: Payment Terms
Common terms:
| Term | Meaning |
|---|---|
| T/T 30/70 | 30% deposit, 70% before shipment |
| L/C at sight | Letter of credit (safer for large orders) |
| T/T 50/50 | For custom or first-time orders |
Safety rule: avoid paying 100% upfront to a new supplier. Use a deposit + balance structure.
Step 6: Quality Control
Protect yourself with:
- Pre-production sample approval
- In-process photos/videos during production
- Third-party inspection (e.g., SGS, BV) for large orders
- Pre-shipment inspection before balance payment
- Clear quality criteria in the contract (AQL standards)
Step 7: Shipping and Logistics
| Term | Who arranges | Best for |
|---|---|---|
| EXW | You arrange everything | Experienced importers |
| FOB | Supplier delivers to port | Most common |
| CIF | Supplier arranges freight | Simpler for beginners |
| DDP | Supplier handles all + duties | Hands-off, higher cost |
Packing: confirm seaworthy export packing (foam + wooden crates) – glass and frames are fragile.
Step 8: Customs and Duties
You’ll need:
- Commercial invoice
- Packing list
- Bill of lading
- Certificate of origin (may reduce duties)
- Compliance documents (CE / NFRC as required)
Before ordering, check:
- Import duty rate for your HS code
- Any anti-dumping duties on aluminum products
- Local building code requirements (codes are enforced locally, not by the supplier)
Common Mistakes to Avoid
- Choosing on price alone – the cheapest quote usually cuts corners (profile, glass, hardware).
- Skipping sample approval – small spec errors become expensive on bulk orders.
- No quality inspection – always inspect before paying the balance.
- Ignoring codes – a supplier’s product must meet your local code, not just theirs.
- Paying 100% upfront – never with a new supplier.
- Vague specs – the more precise your RFQ, the fewer surprises.
