International Supplier Sourcing: Finding and Vetting Overseas Suppliers

For product businesses, the supplier relationship is arguably the most important business relationship you have — more so than customers, because your ability to deliver to customers depends entirely on your supply chain.

International sourcing unlocks cost advantages, product variety, and manufacturing capabilities unavailable domestically — but introduces risks: quality variability, lead time uncertainty, minimum order quantities, communication barriers, and geopolitical risk.

Online sourcing platforms:

• Alibaba.com — largest global B2B marketplace, mainly Chinese suppliers
• Global Sources — similar to Alibaba, strong in electronics and consumer goods
• Made-in-China.com — Chinese manufacturers across all categories
• Kompass — European and global manufacturer directory

Trade fairs:

• Canton Fair (Guangzhou, China) — world's largest trade fair, twice yearly
• Hong Kong Electronics Fair, Cosmoprof — category-specific
• Pure London, Autumn Fair — UK-based but with international exhibitors

Referrals: existing suppliers, trade associations, other founders in your network who have complementary supply chains.

Before placing a first order:

1. Verify they are the manufacturer, not a trading company (unless you want a trading company) — ask for factory photos, audit reports, or a video call from the factory floor

2. Check certifications — ISO 9001 for quality management; CE, FDA, or other product-specific certifications relevant to your markets

3. Request references — ask for contact details of 2–3 existing customers in your country; speak to them

4. Review their terms — minimum order quantities, lead times, payment terms, sample costs, tooling costs

5. Order a sample — evaluate quality, packaging, and lead time on a small order before committing

6. Run a credit or company check — services like Alibaba's Verified Supplier, Bureau van Dijk, or Creditsafe provide background data on larger suppliers

Never pay 100% upfront to a new supplier — standard terms are 30% deposit, 70% on receipt of bill of lading.

Quality control (QC) is the most common failure point in international sourcing. Options:

Pre-shipment inspection (PSI): hire a third-party QC company (Bureau Veritas, SGS, TÜV, AsiaInspection) to inspect your goods at the factory before they ship. Cost: ~$200–400 per inspection day. Essential for first orders and any order over £5,000.

Factory audit: a broader assessment of the supplier's manufacturing processes, management systems, and compliance. Typically done before the first order or when scaling.

Sample approval: require a final production sample (FPS) to be approved before mass production begins. Compare FPS against your original approved sample.

AQL sampling: define an Acceptable Quality Level (typically AQL 2.5 or 1.0 for critical defects) and apply it to inspection. Your QC partner will use a statistically valid sample size.

Once you have established suppliers, use the AskBiz Supplier Scorecard to track their performance across five dimensions: price, lead time reliability, quality, communication, and payment terms.

Ask AskBiz:

• *'Which of my suppliers has the worst on-time delivery rate over the last 6 months?'*
• *'Compare the landed cost of my current China supplier vs the Vietnam alternative I'm evaluating'*
• *'What is the lead time variance on orders from Supplier A?'*

The Supplier Scorecard gives you structured data for supplier reviews and negotiating leverage — and helps you spot deteriorating relationships before they become supply chain crises.
