The conventional playbook for finding overseas suppliers is slow and broken. You pay $5,000 to attend a trade show in Las Vegas, collect 300 business cards, and spend six weeks emailing factories who ghost you, quote you retail prices, or turn out to be trading companies pretending to be manufacturers. Alibaba gives you 4,000 results for "stainless steel fittings" and no reliable way to tell which suppliers actually ship product at scale versus which ones just have a nice storefront.
The problem is information asymmetry. The data that would actually help you — who is shipping what, at what price, to which buyers, how often — exists. It's in customs records. Every shipment that crosses an international border generates a bill of lading or a customs filing that is, in most countries, a matter of public record. For years that data was only accessible to large multinationals who could afford six-figure enterprise contracts. Platforms like Volza have changed that calculus.
This guide walks you through exactly how to use Volza to find, evaluate, and contact overseas suppliers — with specific steps, filter logic, and red flags to watch for at each stage.
What Is Volza?
Volza is a global trade intelligence platform built on top of 3 billion+ shipment records sourced from customs authorities across 209 countries. The core data type is the bill of lading — the legal document issued by a carrier that describes a shipment: what was shipped, how much, from where, to whom, and at what declared value. These aren't surveys. They aren't aggregated estimates. They are the actual transaction documents that move goods through customs, indexed and made searchable across 20+ filter dimensions.
This is the key distinction between Volza and most other sourcing tools. A market research report might tell you that the global market for industrial fasteners is $90 billion. That number is useless when you're trying to decide whether a specific factory in Ningbo is reliable. Volza tells you that the Ningbo factory shipped 47 containers of M8 hex bolts last year to 12 different buyers in 6 countries, with an average declared value of $2.14/kg — and that their shipment volume grew 23% year-over-year. That is actionable intelligence.
Step-by-Step: How to Find Overseas Suppliers on Volza
Step 1: Search by HS Product Code
Don't start with a keyword. Start with an HS code. The Harmonized System (HS) is the international product classification framework used by customs authorities in every country — a 6-digit numeric code that precisely defines a product category. HS code 8517.12 is smartphones. 6204.62 is women's cotton trousers. 3924.10 is plastic tableware. When you search by HS code in Volza, you're matching against the exact product classification that appeared on the customs document, not a keyword that someone typed into a search box.
To find your HS code, use the U.S. International Trade Commission's HTS Search tool at hts.usitc.gov or the World Customs Organization's nomenclature browser. Enter a plain-English description of your product and work through the classification tree. Use 6-digit codes for cross-country searches (the first 6 digits are internationally harmonized). Narrow to 8 or 10 digits if you want country-specific precision.
Pro tip: Search multiple HS codes for the same product. A silicone phone case might classify under 3926.90 (other plastic articles) or 4205.00 (leather goods) depending on the manufacturer's declaration. Cast a wide net at first, then narrow based on what the volume data tells you.
Step 2: Filter by Country of Origin and Shipment Frequency
Once you have HS code results, the two most important filters to apply are country of origin and shipment frequency. Country of origin is obvious — you want to source from China, Vietnam, Bangladesh, Mexico, or wherever makes sense for your product and tariff structure. Shipment frequency is less obvious but more important: it tells you whether a supplier is actively shipping or whether they shipped a handful of containers three years ago and haven't been active since.
Set a minimum shipment frequency that matches your production expectations. If you need a supplier who ships monthly, filter for suppliers with 10+ shipments in the last 12 months. A supplier with 3 shipments in 3 years is a hobbyist exporter — not a factory you want handling your supply chain. Volza lets you filter by shipment count over trailing 12 months, last 3 months, or custom date ranges.
Step 3: Analyze Price Per Unit Trends
Every bill of lading includes a declared value — the price at which the goods were invoiced. Volza aggregates this into a price-per-unit metric, which gives you a real benchmark for what buyers around the world are actually paying, not what a supplier quotes you in a cold email. This is one of the most underused features on the platform.
Use it in two ways. First, as a sanity check: if the market data shows buyers are paying $3.20/unit on average and a supplier quotes you $6.00/unit, you know immediately that you have significant negotiation room — or that the supplier is misrepresenting their cost structure. Second, as a trend indicator: if price per unit for a product category has risen 15% over 18 months, that's a real input cost signal that should inform your pricing model and inventory decisions.
Note: Declared values on customs documents are not always 100% accurate — some exporters undervalue shipments to reduce duty exposure. Treat the price data as a directional benchmark, not a contract price. The trend is almost always more reliable than any single data point.
Step 4: Check Supplier Buyer Diversity
This step separates experienced sourcing managers from first-timers. Before you reach out to any supplier, look at how many distinct buyers they ship to. A supplier with 1 buyer — especially if that buyer is a large retailer — is a concentrated risk. If that relationship ends, the factory's economics collapse, and they'll either cut corners on your order, fail to fulfill, or price you in a way that compensates for their instability.
A healthy supplier profile looks like this: 8–25 active buyers, spread across multiple countries, with no single buyer accounting for more than 40% of shipment volume. Volza shows you the full buyer list for any supplier — company names, countries, shipment counts, and volume share. This is information that would previously require a factory audit or months of relationship building to approximate. Here you get it in 30 seconds.
Step 5: Pull Verified Contacts and Reach Out
Most trade data platforms stop at the company level — you get a factory name and maybe a city. Volza goes further by providing verified contact information for decision-makers at each supplier: direct phone numbers, business email addresses, and LinkedIn profiles for sales managers, export managers, and in some cases founders or CEOs. This data is sourced and verified separately from the shipment records.
When you reach out, lead with the data. Don't cold pitch. Instead, reference what you already know: "I can see you've shipped [product] to buyers in [countries] — we're building a similar supply chain for the [market] and would like to understand your capacity and MOQs." This signals that you're a serious buyer, not a tire-kicker, and puts you in a completely different conversation than the 50 generic RFQs the factory gets weekly from Alibaba.
Competitor Monitoring: The Use Case Everyone Overlooks
The supplier discovery workflow gets most of the attention, but competitor intelligence is where Volza can create real strategic leverage. Because bills of lading are public records, any company's import history is visible. Search your competitor's name as an importer and you'll see every supplier they've used, the volume of product they've pulled, the HS codes they're importing under, and the price per unit they're paying.
This is information that used to require an industry insider or someone willing to work at a competitor. Now it's a few searches. If a competitor just started importing from a factory in Vietnam that you didn't know about, you can identify and approach that same factory before your competitor locks in an exclusive arrangement. If you see a competitor's import volume spike 3x in Q4, that's a signal worth building into your demand planning. Volza lets you set real-time alerts on specific importers, exporters, or product categories so you get notified when something changes without having to log in and check manually.
Volza vs. The Alternatives
There are four serious players in global trade data: Volza, Panjiva (now S&P Global Market Intelligence), ImportGenius, and Trademo. Here is an honest comparison:
Panjiva / S&P Global
The legacy enterprise option. Deep coverage, excellent data quality, robust analyst tools. Pricing starts around $15,000/year for a basic seat and scales well past $50,000 for team licenses. Best for Fortune 500 sourcing teams with dedicated trade compliance staff. Overkill — and financially inaccessible — for most importers, startups, or mid-market brands.
ImportGenius
Strong U.S. import data coverage, reasonably priced for U.S.-centric searches. Global coverage is thinner than Volza and the contact data layer is less developed. Good tool if you're primarily tracking U.S. inbound shipments and don't need deep supplier-side contact enrichment.
Trademo
Newer platform with strong Southeast Asia coverage and a clean interface. Still building out the depth of historical data and contact enrichment that Volza has accumulated. Worth watching, but Volza has a meaningful head start in both data volume and feature set as of 2026.
Volza
Best combination of coverage (3B+ records, 209 countries), contact enrichment (verified phone/email/LinkedIn), filter depth (20+ parameters), and price ($1,500/year Starter). The standout choice for sourcing teams, importers, and founders who want actionable intelligence without enterprise pricing.
Who Volza Is Best For
Volza is not equally useful for everyone. Here's an honest map of who gets the most value from the platform:
- →Importers and brand owners who manufacture overseas and need to vet, compare, and monitor suppliers across multiple countries. This is the core use case and where the ROI is clearest.
- →Dropshippers scaling beyond Alibaba who want to find factory-direct sources instead of trading companies, and who need to benchmark real landed costs before committing to a product.
- →Sourcing consultants and 3PLs who are building supplier shortlists for clients and need defensible, data-backed recommendations rather than directory listings.
- →Trade finance and due diligence teams who need to verify that a company actually ships what they claim, at the volumes they claim, before extending credit or making an investment.
- →Startup founders entering physical goods who need to understand the supply landscape before they can write a credible sourcing strategy or unit economics model.
Volza is less useful if you're entirely domestic, if you're in a services business, or if your product category has extremely thin international trade data (some highly specialized industrial parts, for example, may have sparse records in any platform).
Pricing Reality Check
Volza's Starter plan is $1,500/year. For that, you get access to 90+ countries of direct customs data plus 119 additional countries through mirror data — 209 countries total — with a point-based search system that covers the volume most mid-market sourcing teams actually need.
Compare that to Panjiva's typical entry-level quote of $15,000–$20,000/year for a single user, or the six-figure enterprise licenses that large consumer goods companies pay. The data quality difference between those tiers exists, but it's nowhere near proportional to the price difference. For the vast majority of importers, the intelligence you get from Volza at $1,500/year is more than sufficient to make better sourcing decisions.
Think about it in terms of leverage: if Volza helps you find one better supplier who saves you $0.30/unit on a product you sell 10,000 units of per month, that's $36,000/year in margin improvement from a $1,500 subscription. The ROI math is not complicated.
Bottom Line
Finding overseas suppliers is a data problem that most people are still solving with gut feel, trade shows, and Alibaba browsing. Volza gives you the actual transaction record of global trade — who ships what, to whom, at what price — and makes it searchable with enough filter depth to run a real sourcing process rather than a prayer campaign.
The five-step process above — HS code search, frequency filtering, price benchmarking, buyer diversity check, contact outreach — is repeatable across any product category and any target country. Build it into your standard sourcing workflow and you'll consistently arrive at supplier conversations with more leverage than the buyers who showed up cold.
