How to Import LED Filament Bulbs from China

Step 1: Decide Your Specification Before You Contact Anyone

The biggest mistake first-time importers make: emailing suppliers saying "I want LED filament bulbs, send me your catalog." Any supplier who responds with a price immediately — without asking about your target market, wattage, base type, CCT, CRI, or certification needs — is not vetting the fit. They're just quoting to quote.

Before you contact a supplier, decide:

• Target market — US/EU/Middle East/Australia? Each requires different certifications and base types.
• Bulb shape and base — A19 E26? ST19 E26? B11 E12? G25 E26? Know what your customers need.
• Wattage range — 4W is bright enough for decorative use. 8W if you're replacing 60W incandescent.
• Color temperature — 2700K is warm white (standard for residential). 2200K or 1800K for true vintage / antique amber glow. 3000K–6500K for commercial/utility/daylight applications.
• CRI — 90 is "fine." 95 is "good." 97 is "premium" — and visible in side-by-side comparison, especially on reds and wood tones.
• Dimmable? — If yes, which dimmer types does your market use? (See our dimmable bulb page for details.)
• Certification — UL or ETL for US/Canada. CE + RoHS for EU. SAA for Australia. SASO for Saudi Arabia.
• Packaging — Plain white box? Your own branded box? Retail blister pack? Bulk industrial packing?

Step 2: Vet the Supplier — Not the Alibaba Listing

Alibaba rankings are paid. A supplier at the top of search results bought their way there. Instead of relying on platform rankings, do this:

1. Ask for their certification file number. If they claim UL, ask for the file number and verify it yourself at UL Product iQ. If they won't give you the number, they don't have the certification — end of conversation.
2. Request a sample. Pay for it. A supplier who won't sell you a sample won't sell you a container. When the sample arrives, test it: install it with a dimmer you actually use. Leave it on for 48 hours. Check if the color temperature matches what you ordered.
3. Ask for a video call showing the production line. Not the showroom — the actual production floor. If the supplier deflects or only shows you a meeting room, they're a trading company, not a factory.
4. Check company registration. In China, you can verify a company's business license at the National Enterprise Credit Information Publicity System. If the company name on the license doesn't match the one on the invoice, walk away.

Step 3: Understand the Real Costs

The FOB price you're quoted is only part of the cost. The full picture:

• FOB price — product cost + factory-to-port transport + export documentation
• Ocean freight — currently $1,500–$3,500 per 20ft container (China → US West Coast, fluctuates seasonally). Per-unit cost depends on how many bulbs fit in your container.
• Customs bond — roughly 0.5% of cargo value for US imports (minimum $25–$75 per entry)
• US import duty — LED bulbs are classified under HTS 8539.52.0050. Current duty rate for Chinese-origin LED lamps: check with your customs broker; additional Section 301 tariffs may apply.
• Inland trucking — port to your warehouse or Amazon FBA center, roughly $0.50–$1.50 per mile depending on distance
• Warehousing — if you're not sending directly to Amazon, budget ~$0.50–$1.00 per pallet per month

Step 4: Don't Skip Pre-Shipment Inspection

Even with a good supplier, production batches vary. Before your goods leave the factory, have them inspected. You can hire a third-party inspection company (SGS, Bureau Veritas, or local firms) for roughly $300–$500 per day. The inspector checks:

• Random sample AQL inspection (usually AQL 2.5)
• Functionality test — every sampled bulb powered on, dimmed, checked for flicker
• Visual inspection — glass defects, filament alignment, printing quality on the base
• Packaging integrity — box condition, labeling accuracy, barcode scannability
• Carton drop test — a packed carton dropped from shoulder height to simulate shipping handling

Pre-shipment inspection costs $300–$500. A container of defective bulbs costs $10,000+ to fix and damages your relationship with your customers. The math is obvious.

Step 5: Plan Your Shipping Timeline

• Production lead time: 30–45 days from order confirmation (longer for OEM with custom tooling)
• Ocean transit: 18–25 days China → US West Coast; 30–35 days China → US East Coast; 28–35 days China → Europe
• Customs clearance: 2–5 days (if documentation is complete)
• Inland delivery: 2–7 days depending on destination
• Total timeline from order to warehouse: 60–90 days

Plan your inventory 3 months ahead. LED filament bulbs won't go bad in transit, but running out during peak season (October–December for holiday lighting demand) means lost revenue you can't recover.
