Key Definitions

Lumen Output (lm)
Total visible light emitted. More meaningful than wattage for brightness comparison. Always verify via IES LM-79 test report, not manufacturer claims.
CRI (Color Rendering Index)
0-100 scale measuring color accuracy. CRI ≥80 for general commercial; CRI ≥90 for retail and healthcare. Check R9 (red) value separately.
IP Rating (Ingress Protection)
Two-digit code per IEC 60529. First digit: solid protection (0-6). Second: liquid protection (0-9). IP65 = dust-tight + water jets. IP20 = indoor only.
Efficacy (lm/W)
Lumens per watt. Commercial LED fixtures achieve 100-150 lm/W. System efficacy is lower than LED package efficacy due to driver and optical losses.

Quick Answer

A standard LED export order from China involves 10 critical milestones: RFQ → Sample → Commercial negotiation → Purchase Order → Deposit → Production → Pre-shipment inspection → Customs clearance (export) → Shipping → Delivery. The most common delays occur at milestones 3–5 (negotiation, PO confirmation, deposit receipt) and milestone 7 (pre-shipment inspection scheduling). Understanding this timeline helps you plan lead times, set buyer expectations, and identify where delays are most likely to occur.

The 10 Milestones in Order

Milestone Duration Key Documents Delay Risk
1. RFQ received Day 0 Product spec, quantity, target price, delivery date Low
2. Sample submission 2–4 weeks Sample unit(s), test report, datasheet Medium
3. Commercial negotiation 1–3 weeks Revised quotation, Incoterms, payment terms High
4. Purchase Order confirmed Day 0 Signed PO with all commercial terms Medium
5. Deposit received 1–5 business days SWIFT confirmation, bank statement High
6. Production 3–6 weeks Production schedule, QC plan Medium
7. Pre-shipment inspection 1–2 days before shipment PSI report, AQL standard Medium
8. Export customs clearance 1–3 days Export declaration, CI, PL, BL Low
9. Ocean freight 10–35 days B/L, packing list, insurance policy Low
10. Import customs clearance + delivery 3–10 days Import declaration, duty payment Medium

Common Delays and How to Prevent Them

Delay at Milestone 3 (Negotiation): The most common cause is buyers requesting DDP pricing without providing destination country import duty details. Prevention: Require buyers to provide HS Code and import duty confirmation before quoting DDP.

Delay at Milestone 5 (Deposit): International wire transfers from some countries (Nigeria, Pakistan, Bangladesh) can take 5–7 business days. Prevention: Confirm wire transfer timeline with your bank before quoting lead times.

Delay at Milestone 7 (Pre-shipment Inspection): PSI companies are often booked 2–3 weeks in advance during peak season (Q3). Prevention: Schedule PSI at the same time you confirm the production completion date with the factory.

Final Decision

Build your order timeline backwards from the buyer’s required delivery date. Subtract ocean freight time (10–35 days), import clearance time (3–10 days), and your production lead time (3–6 weeks) to determine your sample submission deadline. Communicate this timeline clearly to the buyer at the start of each order. Set milestone deadlines in writing in the Purchase Order.

Key Takeaways

  • A standard LED export order timeline: RFQ → sample (2–4 weeks) → production (3–6 weeks) → shipping (10–35 days sea freight) = 6–12 weeks total from PO to delivery
  • Pre-shipment inspection (PSI) must be scheduled at least 2–3 weeks ahead during peak season (Q3) , book the inspector early
  • Deposit receipt is the start signal for production . do not begin production until the deposit has cleared in your bank account
  • Build your timeline backwards from the buyer’s required delivery date and set milestone deadlines in the Purchase Order

FAQ

Q: Can I start production before the deposit clears if the buyer is a long-term customer? A: No, even with trusted buyers, always wait for deposit clearance. Bank transfers can be recalled, payment instructions can be disputed, and buyer financial situations can change between sending the wire and it clearing. The risk of starting production without a cleared deposit is a factory full of inventory belonging to a buyer who has not paid.

Q: What is the typical production lead time for LED luminaires from a Chinese factory? A: For orders of 500–2,000 units of a standard LED luminaire (panel, downlight, high bay), production typically takes 3–4 weeks after deposit clearance. For new product development (custom housing, custom PCB, new LED chip selection), add 2–3 weeks for LED binning verification and optical testing. For orders above 5,000 units, add 1–2 weeks for capacity ramping.

Q: Who books the pre-shipment inspection and who pays for it? A: Standard practice is for the buyer to instruct and pay for the PSI. However, the exporter should coordinate the inspection scheduling with the factory. If the buyer does not arrange PSI, the exporter should recommend a reputable company (SGS, Bureau Veritas, QIMA) and request the buyer to instruct them, this protects both parties.
