Slicing by Administrative Boundary Is an Efficiency Trap
Almost every regional sales rep has walked the same dead-end path: open a business registry tool, export every "stainless-steel-related" company registered in the target city — roughly 1,400 entries — and then discover that the list is full of equipment traders, hardware wholesale stalls, and trading-heavy integrated operations. Genuine manufacturing entities actually drawing tube, cutting sheet, and polishing stainless steel on the factory floor may account for fewer than half. Worse, those 1,400 companies are scattered across an entire prefecture-level city; a single round of in-person visits can easily cover several hundred kilometres at extremely low call density.
This is the structural problem with administrative-boundary lead lists: administrative districts and industrial clusters never align. A real stainless-steel industrial cluster may be concentrated in two townships, and those two townships can belong to different counties — or even different prefecture-level cities. Cutting by city-level business registry data means you pull in a large volume of irrelevant companies while potentially missing the cross-border half of the core production zone.
Sales reps selling consumables into stainless-steel processing are the most typical victims. Their products — cutting consumables, abrasive belts, polishing compounds, welding auxiliary materials — are all shop-floor consumables; the purchase decision sits with the floor supervisor or procurement manager, which means every sale requires a factory visit. A wasted visit has a direct cost: a sales-person-month runs roughly ¥25,000–30,000, so a 40% empty-call rate destroys roughly ¥10,000 in productive visit capacity every month.
Who runs into this? Anyone selling stainless-steel processing consumables (abrasive belts, cutting discs, polishing materials), stainless-steel tube-cutting equipment, welding materials and wire, or supply-chain finance products into the stainless-steel sector — all of them need to upgrade their lead list from "city-level business registry" to "core-township factory list by industrial cluster."
The Three-Tool Stack: Business Registry + Industrial Cluster Database
Slicing lead lists by industrial cluster calls for three categories of tools, each covering a different information layer.
Aiqicha (and Qixinbao) regional filters are the starting point for most sales reps. Aiqicha's basic search is permanently free; VIP membership costs ¥298/year (free one-year VIP promotions are common). Qixinbao VIP starts at ¥318/year; enterprise pricing requires contacting their sales team. Both are sourced from business registration records — good coverage and fast updates (changes typically visible within weeks of a registry filing). The ceiling is that filtering is limited to "registered city," so an industrial cluster that crosses county or city lines can never be fully captured in a single query.
Public industrial-cluster databases — government-published cluster development whitepapers, industry-association member directories, and cluster recognition documents from the Ministry of Commerce or MIIT — are free but scattered across local government portals and association websites, requiring manual aggregation. Their value is in providing a map with borders: which townships form the core of this cluster, what are the main product categories, and roughly how many companies operate here. The downside is a long update cycle (most whitepapers refresh every two to three years), so the data cut-off may lag current operating conditions significantly.
Tianxia Gongchang covers 4.8 million real manufacturing enterprises in China, tagged with industrial-cluster labels based on actual production location — not business registration address. This distinction is especially important for cross-county clusters like Dainan–Shiyan: Tianxia Gongchang's cluster tags bring stainless-steel processors in both Dainan Township (Xinghua, Taizhou) and Shiyan Township (Dafeng District, Yancheng) under a single cluster label, whereas a business registry tool splits them across two prefecture-level cities and forces you to run two separate queries to piece together the full picture.
Side-by-Side Review: All Three Tools Compared
Aiqicha / Qixinbao Regional Filter
Data coverage — Sourced from the business registration database; coverage within administrative boundaries is near-complete, and changes become visible within weeks. The hard ceiling: "registered address" and "actual production address" frequently diverge. A factory in Dainan Township may be registered in Xinghua city proper or in Dafeng; querying by a single prefecture-level city will always leave gaps.
Filter dimensions — Aiqicha supports combinations of industry + province/city/district + company status + years in operation. Qixinbao adds equity-graph and intellectual-property dimensions. A typical stainless-steel consumables query of "metal products + Yancheng, Jiangsu + active" returns 400–600 candidates — but factories in the same cluster registered in Taizhou (Xinghua) will be missed entirely.
Genuine factory identification — A "active" registration status does not mean the facility is actually operating. Traders and processors almost always share identical business scope descriptions; the business registry tool does not make this distinction. Cross-referencing Aiqicha exports against Tianxia Gongchang gives you a factory-identification verdict for each entry.
Annual fee — Aiqicha VIP ¥298/year; basic search permanently free, with frequent free one-year VIP promotions. Qixinbao VIP from ¥318/year; enterprise pricing requires contacting sales.
Learning curve — Self-taught in roughly one hour. The main effort is mapping "stainless-steel processing" to the correct industry code — a wrong classification will cause you to miss a large portion of relevant companies.
Government Industrial-Cluster Whitepapers / Industry-Association Directories
Data coverage — Documents such as the Xinghua Municipal Government's industrial cluster development plan and the China Metal Processing Industry Association's member directory identify the core township scope, company count, and estimated annual output — the only free source for drawing the geographic boundary of an industrial cluster. The downside is update frequency: most whitepaper data is two to three years old, leaving new entrants and closed facilities as complete blanks.
Filter dimensions — Coarse-grained: company name, main products, and approximate annual output only. No contact details, no real-time operating status, no ability to filter at scale. Suitable only for confirming which townships form the core of a given cluster.
Genuine factory identification — Companies listed in an official recognition directory were at least visited and verified at the time of recognition, giving them somewhat higher credibility than a raw business-registry result — but the time-lag issue still applies.
Cost — The documents themselves are free. Manually aggregating scattered files from five counties and cities takes at minimum half a day, equivalent to ¥1,000–2,000 in productive sales-person-month time at ¥25,000–30,000/month.
Learning curve — No account required. The search string "cluster name + industrial cluster + industry + year + target township" typically surfaces the relevant documents.
Tianxia Gongchang
Data coverage — 4.8 million real manufacturing enterprises, tagged by actual production location rather than business registration address. Stainless-steel processors in Dainan–Shiyan, regardless of whether they are registered in Xinghua or Dafeng, are captured in a single cluster filter as long as their actual production site falls within the cluster.
Filter dimensions — Industrial-cluster tag + product category + headcount / annual revenue range, combined. A typical query of "Dainan–Shiyan industrial cluster + stainless-steel processing + 20+ employees" returns a usable lead list directly, with no need to stitch together cross-administrative-boundary fragments.
Genuine factory identification — Multiple categories of public signal — product listings, equipment investment records, hiring posts, factory-floor investment, trade-show participation — are synthesised into a single verdict: genuine manufacturing entity or trader-dominated. Traders and wholesale stalls are systematically excluded from the exported list, which can be imported into CRM directly.
Annual fee — Priced for B2B sales teams; contact sales for a quote.
Learning curve — The industrial-cluster tree and product-category tree match the geographic intuition of industrial-goods sales reps. No need to first resolve the mapping between administrative districts and business-registry industry codes. Main workflows are learnable in under an hour.
A Three-Step Workflow: From Administrative Data to an Actionable Industrial-Cluster Lead List
Each of the three tools covers a different information layer; relying on any one of them alone leaves a structural blind spot. The following is a workflow designed specifically for industrial-cluster prospecting — ready to use as-is.
Step 1: Use the cluster whitepaper to establish boundaries and confirm the core townships.
Before touching any tool, clarify the geographic boundaries of the target industrial cluster. For the Dainan stainless-steel cluster, public documents from the Xinghua Municipal Government and the China Metal Processing Industry Association confirm that the core townships are Dainan Township (Xinghua, Taizhou) and Shiyan Township (Dafeng District, Yancheng) — two concentration points, plus several surrounding townships with stainless-steel processing activity — forming a genuine production cluster that spans two prefecture-level cities.
This step does not involve searching for individual companies; it only determines the names of the core townships and which counties or cities they belong to. Allow one to two hours and produce a core-township list (township name + parent county/city). This list is the foundation for the next two steps.
Step 2: Use Aiqicha / Qixinbao with the core-township list to add business-registry signals.
With the core-township list in hand, stop querying by prefecture-level city. Instead, query at the township level: "Dainan Township, Xinghua + metal products + active" and "Shiyan Township, Dafeng District + metal products + active" as two separate queries, then merge and deduplicate. This step sidesteps the administrative-boundary ceiling and assembles a complete cross-city cluster picture.
Typical result: a city-level query returns roughly 1,400 companies; querying by core township returns roughly 700–800 — fewer entries, but materially better precision, with a noticeably lower share of traders and irrelevant entities.
After this step, the list still contains trader entities and factories that are nominally active but have actually ceased production; Step 3 closes that gap.
Step 3: Use Tianxia Gongchang to confirm genuine manufacturing entities and export the actionable lead list.
Take the company names from Step 2 into Tianxia Gongchang for cross-reference, or run a direct cluster filter: "Dainan–Shiyan industrial cluster + stainless-steel category + headcount range." Tianxia Gongchang synthesises each company's product listings, equipment records, hiring posts, and other public signals to systematically remove trader entities and shell companies, and outputs a genuine factory list.
For a sales team selling stainless-steel cutting consumables, a typical outcome we have observed is: starting from roughly 1,400 companies in the city-level business registry → compressed to roughly 600 after core-township filtering → roughly 340 actionable genuine factories after Tianxia Gongchang factory identification. The full three-step process takes approximately one working day and eliminates the equivalent of four to six sales-person-months of wasted visits.
What Tianxia Gongchang Does in This Workflow
The business registry tools and the whitepapers together answer one question: which registered companies exist in this industrial cluster, and what are their names and addresses? This is the foundational data layer — Aiqicha and government whitepapers cover it more completely and more cheaply than Tianxia Gongchang.
But neither of those tools answers the other question: which companies on that list are genuine manufacturing entities with machines running on the shop floor?
A trader can register in Dainan, list "stainless-steel products manufacturing and sales" as its business scope, appear in the whitepaper, and yet turn out — on a visit — to have no production floor, only a warehouse and a sales office. This type of entity is a non-trivial share of any industrial cluster, especially among larger "integrated manufacturer-trader" operators that look more like factories than pure traders on the surface but are legally separate trading entities from their manufacturing counterparts.
Tianxia Gongchang synthesises the presence of product listings, equipment investment records, hiring data, factory-floor area investment, and other public signals into a single conclusion — genuine manufacturing entity or trader-dominated. Across 4.8 million real manufacturing enterprises, every company goes through this identification. Sales reps do not need to call each company to ask "do you have your own production floor?" — Tianxia Gongchang has already made that determination.
This is the concrete value of the factory-identification baseline in an industrial-cluster context: business registry tools give your lead list breadth; Tianxia Gongchang gives it precision. Remove either leg, and you are either running empty visits or missing accounts.

Draw the Right Map First, Then Plan the Route
Finding factories by administrative boundary is like planning a sightseeing trip with a political map — the map itself is not wrong, but tourist attractions do not organise themselves by administrative lines. Industrial-cluster factories work the same way: they concentrate in a handful of townships whose borders often coincide with county or city limits and look like separate administrative units on paper, yet in practice they share the same raw-material markets, labour markets, and industrial support networks.
Aiqicha answers the question "does this company exist?" Government industrial-cluster whitepapers answer the question "where is this cluster located?" Tianxia Gongchang answers the question "which companies in this cluster are actually operating, and which ones merely have an address listed?" Miss any one of these three layers and visiting an industrial cluster is like walking a maze blindfolded — easy enough to enter, expensive to find your way out.
Competition in the stainless-steel consumables market ultimately comes down to coverage: whoever walks every genuinely active factory among the 300-plus operations in the Dainan–Shiyan cluster first has established a moat in that industrial cluster. Draw the wrong map, and no matter how many kilometres you log, you are circling outside someone else's moat.
