How to Source Private Label Products from China: End-to-End Guide

What Is Private Label Sourcing?

Private label sourcing means finding a factory that manufactures a generic product, then selling it under your own brand. The factory makes it; you brand and sell it. This is how most Amazon FBA sellers operate, how many DTC brands are built, and how large retailers like Costco create their Kirkland Signature line.

The economics work because factories charge 20-60% of the eventual retail price for manufacturing. The branding and distribution markup — the part you control — is where the value is created.

Step 1: Product Validation Before Sourcing

The most common private label mistake is sourcing before validating demand. Before contacting a single supplier:

BSR below 10,000 in a category typically means the product sells 10+ units per day. Use Jungle Scout or Helium 10 to convert BSR to estimated monthly sales.

Filter by 5 years. Avoid seasonal spikes unless you're prepared to manage seasonal inventory. Flat or growing trends are better than peaks.

Target: 30%+ gross margin after COGS (landed cost) and Amazon FBA fees. If a comparable product sells for $30 and Amazon fees are $10, your landed cost must be below $9 to hit 30% margin.

Look at the top 10 listings. If all 10 have 10,000+ reviews and are from established brands, the category is too competitive. Find niches where the top sellers have 500-2,000 reviews.

Step 2: Finding Suppliers on 1688 and Alibaba

1688.com is China's domestic B2B marketplace — factory-direct pricing, 30-60% cheaper than Alibaba.com international, but Chinese-only interface. Alibaba.com is the international version — English UI, higher prices, Trade Assurance protection.

For private label sourcing, the typical workflow is:

1. Search both platforms for suppliers of your product category
2. Use 1688 pricing as the baseline (factory-direct cost)
3. Use Alibaba for first-time orders if you need Trade Assurance protection

Install the Source Finder Chrome extension and open any Amazon product page. Click the extension icon to run a simultaneous image + keyword search across 1688 and Alibaba. Results show within 30-60 seconds with:

• Supplier price ranges (by order quantity)
• Minimum order quantities
• Gold-supplier years (proxy for reliability)
• Transaction volume

This gives you 10-30 factory matches without any Chinese language skills.

Use Google Translate to search for your product category in Chinese. Add "工厂" (factory) to filter out trading companies. Add "OEM" or "定制" (customization) to find factories that do private label.

Step 3: Evaluating and Shortlisting Suppliers

After identifying 10-20 potential suppliers, narrow to 3-5 using these criteria:

More years of Gold Supplier status on 1688 or Alibaba indicates a stable, ongoing business. Prefer 3+ years. 10+ years is excellent.

Higher transaction counts mean more experience fulfilling orders. Very low volumes on an established account is suspicious.

On 1688, "实地认证" means Alibaba staff physically visited and verified the factory. Prioritize these.

Send an inquiry and measure response time. Factories that respond within 24 hours are better operational partners. Very slow or generic copy-paste responses are red flags.

Can they do custom packaging, logo printing, and slight product modifications? Private label requires this. Ask specifically: "Can you print my brand logo on the product and packaging?"

Step 4: Requesting Samples

Never skip samples. The cost of sampling ($50-200 per supplier) is trivially small compared to the cost of ordering 500 defective units.

Product: [describe your product]
Target quantity for first order: [e.g., 500 units]
Customization required: [logo, packaging, color options]
Target unit price: [your budget]
Shipping: I will arrange my own freight forwarder
Questions:
1. What is your minimum order quantity?
2. Can you provide product samples? What is the sample cost?
3. What is your typical lead time for production?
4. Do you have experience with private label / OEM production?

Use Catalayer Sourcing Agent to generate and send this RFQ automatically after selecting suppliers from Source Finder results.

• Does it match the photos and specifications exactly?
• Check dimensional accuracy (measure with calipers for precision products)
• Test durability: drop tests, stress tests, repeated-use tests
• Compare to competitor products on Amazon

Step 5: Negotiating Terms

Once you have 3 competing quotes, you have leverage. Tell your preferred supplier: "I have a lower quote from another factory. Can you match $X per unit at [your target quantity]?" Getting a 10-20% price reduction through negotiation is normal.

Standard: 30% deposit upfront, 70% before shipping. For trusted long-term suppliers: 20%/80%. Never pay 100% upfront to a new supplier.

Get lead time in writing. Standard production runs: 15-30 days for simple products, 45-60 days for complex or tooled products. Add 5-7 days buffer.

For unique product designs, include a confidentiality clause in your purchase order. Larger factories are accustomed to these requests.

Step 6: Freight and Import

For 1688 orders: most freight forwarders offer a "buy and ship" service where they handle payment (via Alipay) and ship to your address. Fee is 5-10% of order value.

• Air freight: 5-10 days, expensive (~$8-15/kg). Good for first orders and seasonal restocking.
• Sea freight LCL (less than container load): 25-40 days, $100-400 per CBM. Best for 50-300 kg shipments.
• Sea freight FCL (full container): 25-40 days, $1,500-4,000 per 20-foot container. Best for large volumes.

• Commercial invoice
• Packing list
• Bill of lading / airway bill
• Certificate of origin (if needed for preferential tariff rates)
• Any product-specific certifications (CE, FCC, CPSC)

US Customs charges duty on most products. Rates vary by HTS code (product category). China-origin goods may face additional Section 301 tariffs (7.5%-25% on many categories). Calculate the total landed cost including duty before committing to a sourcing price.

Monitoring Your Product Category

After launching a private label product, ongoing competitive intelligence matters. Use Catalayer News Monitor to track:

• Competitor product launches in your category
• Regulatory changes affecting your product type
• Raw material price changes (e.g., aluminum prices for metal goods)
• Import/export policy changes affecting China-sourced products

Set a Monitor rule: ([your product category] AND (launch OR new OR recall OR regulation)) OR ([competitor brand names] AND (product OR release)).

Common Mistakes to Avoid

1. Ordering too much on the first run — Start with 100-200 units to validate sell-through before committing to a full production run
2. Skipping third-party quality inspection — $200 for a pre-shipment inspection by SGS, Bureau Veritas, or Asia Inspection is mandatory for any order over $2,000
3. Using the factory's packaging — Custom branded packaging increases perceived value and ASP by 20-40%
4. Not verifying certifications — A factory claiming FCC or CE certification should be able to provide test reports from a recognized lab
5. One supplier dependency — Always qualify a backup supplier after your first order succeeds
