China B2B Sourcing Checklist for North American Buyers: 2025 Edition
A step-by-step reference for US and Canadian importers sourcing from Chinese manufacturers — from supplier discovery through to delivery
China remains the world's dominant supplier of manufactured goods for North American buyers — from small commodities and consumer electronics to industrial parts and apparel. But the sourcing process has real failure points at every stage. This checklist covers each phase so you don't miss a critical step.
Phase 1: Supplier Discovery
PHASE 1 Finding the Right Suppliers
Define your sourcing criteria first — product category, target MOQ, max unit price, required certifications (CE, UL, CPSC, etc.)
Choose the right sourcing channel for your category — Alibaba (general), Global Sources (electronics), Yiwu/MapleBridge (small commodities), Made-in-China.com (industrial), Canton Fair (high volume)
Contact minimum 5–8 suppliers per product category — response rates are low; cast a wide net
Send identical RFQ (Request for Quotation) to all — standardize what you're asking so you can compare apples-to-apples
Include target unit price in RFQ — suppliers respond more seriously when you show price awareness
Phase 2: Supplier Vetting
PHASE 2 Verifying Supplier Legitimacy
Request a live video factory tour — any legitimate factory will agree to this in 2025. A refusal is a red flag.
Verify business registration — ask for their 营业执照 (Business License). Cross-check company name on China's National Enterprise Credit Information System (gsxt.gov.cn)
Confirm factory vs. trading company — ask directly if they manufacture in-house or source from other factories. Both are workable, but pricing and lead times differ.
Check certifications relevant to your market — BSCI (labor standards), ISO 9001 (quality management), CE (EU/EU-aligned markets), UL/CPSC (US electrical safety), CSA (Canada)
Ask for 3 existing customer references — legitimate suppliers can usually provide contact details for other buyers in your region
Check Alibaba/trade show history — years on platform and exhibition history signal established operations
⚠️ Trading company vs. factory: Trading companies are legitimate intermediaries, but they add 10–20% markup. For repeat, high-volume orders, going direct to the factory pays off. For one-time or low-volume orders, a trading company may actually be faster and more reliable.
Phase 3: Sampling
PHASE 3 Sample Ordering & Evaluation
Order samples from top 2–3 shortlisted suppliers — never skip this step, even for repeat product categories with a new factory
Label each sample clearly — if ordering from multiple suppliers simultaneously, mark the packaging immediately to avoid confusion on arrival
Evaluate against written spec sheet, not memory — create a simple scoring rubric: dimensions, material, finish, packaging, function
Confirm bulk production will match sample — get written confirmation that production specs will match the approved sample
Test compliance certifications on samples if required — for regulated categories (toys, electronics, personal care), test samples at a US/Canadian lab before committing to production
Phase 4: Ordering & Payment
PHASE 4 Contracts, Terms & Payment
Use a written Purchase Order (PO) — include: product specs, quantity, unit price, delivery date, payment terms, packaging requirements, port of loading
Payment terms: 30% deposit, 70% balance before shipment — this is standard. Never pay 100% upfront for a first order with a new supplier.
Pay via T/T (wire transfer) to verified company bank account — confirm bank account matches the company name on the business license
Avoid paying to personal accounts or WeChat Pay for large orders — only acceptable for very small sample payments
Specify FOB (Free On Board) pricing — FOB means supplier delivers to port, you control freight. CIF (Cost, Insurance, Freight) means supplier arranges shipping — convenient but you lose control over freight costs.
Confirm HS codes for your products — both Chinese export HS code and North American import HS code. Tariff rates vary significantly by category, especially under current US-China trade policy.
Phase 5: Quality Control
PHASE 5 Pre-Shipment Inspection
Book a third-party inspection for orders over $5,000 — SGS, Bureau Veritas, and QIMA offer pre-shipment inspections in China for $200–350 per inspection day
Provide inspectors with your original approved sample and spec sheet — inspectors compare production against your documented standards, not their judgment
Inspect before releasing final payment — release the 70% balance only after inspection passes
Check carton count and labeling against PO — verify quantity, inner pack configuration, and labeling match what was ordered
Phase 6: Shipping & Import Compliance
PHASE 6 Logistics & Customs
Use a licensed customs broker — required for commercial imports into the US (CBP) and Canada (CBSA)
Confirm current tariff rates before placing order — US Section 301 tariffs on Chinese goods range from 7.5% to 25%+ depending on category. Canada has separate tariff schedules.
Prepare commercial invoice, packing list, and bill of lading — standard required documents for customs clearance
Verify product safety compliance for North American market — CPSC (US consumer products), Health Canada (Canadian consumer products), FCC (US electronics), ISED (Canadian electronics)
Calculate total landed cost before committing — unit price + freight + customs duties + broker fees + warehousing. Common mistake: orders that look profitable at ex-factory price are unprofitable after duties.
US vs. Canada: Key Import Differences
| Item |
United States |
Canada |
| Customs Authority | CBP (Customs and Border Protection) | CBSA (Canada Border Services Agency) |
| China Tariffs | Section 301: 7.5–25%+ by category | Standard MFN rates (lower than US Section 301) |
| De Minimis Threshold | $800 USD (as of 2025) | $20 CAD formal entry threshold |
| Product Safety | CPSC, FCC, FDA (food/health) | Health Canada, ISED, CFIA (food) |
| Electrical Standards | UL / ETL | CSA / cUL |
| Children's Products | ASTM F963, CPSIA | Canada Consumer Product Safety Act |
The Most Common Sourcing Mistakes (and How to Avoid Them)
- Skipping the sample stage to save time — the single largest cause of failed first orders. Always sample.
- Choosing supplier based on price alone — the cheapest quote often reflects lower material grade, higher defect rate, or a trading company obscuring a factory that can't deliver.
- Failing to calculate landed cost before committing — many first-time importers discover that duties make their order unprofitable after the goods have shipped.
- Not specifying packaging requirements — assume nothing. Specify inner pack, master carton dimensions, labeling, and barcoding in your PO.
- Letting the communication gap kill the spec — EN↔ZH misunderstandings on dimensions, materials, and colors are responsible for a majority of failed bulk orders. Use bilingual documentation for anything spec-critical.
