Step 2: Understanding the Quotation

Chinese suppliers typically quote in USD with these terms:

Common Incoterms

  • EXW (Ex Works): Price at factory gate. You arrange everything from factory.
  • FOB (Free on Board): Price includes delivery to Chinese port + export customs. Most common for windows.
  • CIF (Cost, Insurance, Freight): Price includes ocean freight and insurance to your port.
  • DDP (Delivered Duty Paid): Price includes everything to your doorstep. Rare for windows due to complexity.

What’s Included in the Price

  • ✅ Aluminum profiles (6063-T5/T6)
  • ✅ Glass (tempered, double/triple glazed)
  • ✅ Hardware (hinges, handles, locks)
  • ✅ Rubber gaskets and seals
  • ✅ Assembly labor
  • ✅ Protective packaging
  • ✅ Quality inspection before shipment
  • ❌ Ocean freight (unless CIF)
  • ❌ Import duties and taxes
  • ❌ Customs clearance fees

Hardware$8-2010-15%
Accessories (gaskets, etc.)$3-54-5%
Labor & Assembly$5-86-8%
Packaging$2-43-4%
Total FOB Price$73-127100%

Step 3: Sample Order – Critical Step!

Never skip the sample order. Always test a sample window before placing bulk order.

Sample Order Process

  • Sample Size: 1-2 typical windows (e.g., 1200×1500mm)
  • Sample Cost: $300-600 (2-3× unit price, includes custom production)
  • Sample Lead Time: 5-7 days production + shipping
  • Shipping: Air freight (7-10 days) or sea LCL (20-35 days)
  • Sample Cost Refund: Often refunded with bulk order (negotiate this!)

What to Test on Samples

  • ✅ Profile quality (wall thickness, finish, thermal break)
  • ✅ Glass quality (tempering mark, spacer, sealant)
  • ✅ Hardware operation (smooth opening/closing)
  • ✅ Air/water tightness (simple spray test)
  • ✅ Color match (compare to RAL swatch)
  • ✅ Dimensions (verify against your specifications)
  • ✅ Packaging (sufficient for ocean freight?)

Red Flags in Samples

  • ❌ Profile wall thickness < 1.4mm (should be 1.4-2.0mm)
  • ❌ Rough or uneven powder coating
  • ❌ Hardware feels cheap or sticky
  • ❌ Glass spacer not straight or sealant messy
  • ❌ Dimensions off by >2mm
  • ❌ Color significantly different from RAL sample

Step 4: Payment Terms & Security

Standard Payment Terms

  • 30% Deposit: Paid after sample approval, before production
  • 70% Balance: Paid after production, before shipment (against photos/videos)
  • Payment Method: T/T (bank transfer) most common
  • L/C (Letter of Credit): Available for large orders ($100K+)

Payment Security Tips

  • ✅ Verify bank account matches company name (not personal account)
  • ✅ Use company email domain for all communication
  • ✅ Request business license and export license copies
  • ✅ Consider Trade Assurance (Alibaba) for first orders
  • ✅ Never wire 100% upfront (standard is 30/70)
  • ✅ Keep 5-10% retention for large projects (pay after installation)

Bank Transfer Information (Example)

  • Beneficiary: Foshan Rogenilan Windows & Doors Co., Ltd.
  • Bank: [Chinese bank name]
  • SWIFT: [SWIFT code]
  • Account: [Account number]
  • ⚠️ Always verify with supplier directly before transferring!

Step 5: Production & Quality Control

Production Timeline

  • Profile Cutting & Machining: 3-5 days
  • Assembly: 5-8 days
  • Glass Installation: 3-5 days
  • Quality Inspection: 2-3 days
  • Packaging: 1-2 days
  • Total: 15-25 days (standard orders)

Quality Inspection Checklist

  • ✅ Profile wall thickness (caliper measurement)
  • ✅ Thermal break continuity (visual inspection)

  • ✅ Spacer and desiccant (check for gaps)
  • ✅ Hardware operation (open/close 10+ times)
  • ✅ Sealant application (continuous, no gaps)
  • ✅ Color consistency (compare to approved sample)
  • ✅ Dimensions (random sample measurement)

  • Intertek: $300-500 per day
  • Local Inspector: $200-300 per day (hire via Upwork or local contacts)

Recommendation: For orders >$50K, hire third-party inspection. Worth the cost to avoid costly mistakes.

Australia5%10% GSTNo
UK0-4%20% VATNo
Germany0-4%19% VATNo
UAE5%5% VATNo
Singapore0%8% GSTNo

Customs Clearance Process

  1. Hire customs broker (or use freight forwarder’s service)
  2. Submit documents (invoice, packing list, B/L, certificates)
  3. Pay import duties and taxes
  4. Customs inspection (if selected)
  5. Release and pickup from port

Typical Clearance Time: 3-7 days (depends on country and documentation)


Step 8: Installation Considerations

Installation Options

  • DIY Installation: Possible for experienced contractors. Save 30-50% on labor.
  • Local Installer: Hire local window installation company. Typical cost: $30-60/m².
  • Supplier’s Installer: Some suppliers offer installation teams (rare for overseas).

Installation Best Practices

  • ✅ Verify opening dimensions before installation
  • ✅ Use proper shims for leveling (never force windows)
  • ✅ Apply waterproof membrane or flashing tape
  • ✅ Use low-expansion foam for insulation (not regular foam!)
  • ✅ Seal exterior joints with quality sealant (Sikaflex or equivalent)
  • ✅ Test operation after installation (adjust if needed)
  • ✅ Remove protective film within 30 days (prevents adhesive residue)

Common Installation Mistakes

  • ❌ Forcing windows into undersized openings (causes frame distortion)
  • ❌ Skipping waterproofing (leads to water infiltration)
  • ❌ Using regular expanding foam (can warp frames)
  • ❌ Not leveling properly (causes operational issues)
  • ❌ Leaving protective film on too long (adhesive bakes in sun)

Total Cost Comparison: China vs Local

Example: 100 m² Thermal Break Series Windows

Cost ComponentChina ImportLocal Supplier (USA)
Window Units (FOB)$10,000$18,000
Ocean Freight (FCL)$2,500
Import Duties (5%)$500
Customs & Broker Fees$400
Inland Transport$800$500
Installation$4,000$5,000
Total$18,200$23,500

Savings$5,300 (22.5%)

Note: Savings vary by country, order size, and local labor costs. Larger orders typically save 30-40%.


Risk Mitigation Checklist

  • ✅ Order samples before bulk production
  • ✅ Use written contracts with clear specifications
  • ✅ Hire third-party inspection for orders >$50K
  • ✅ Keep 5-10% payment retention until after installation
  • ✅ Verify all certifications match your country’s requirements
  • ✅ Use reputable freight forwarder (not supplier’s default)
  • ✅ Purchase cargo insurance (0.3% of cargo value)
