Glaze Sellers and Kiln Sellers Are Both Looking in the Wrong Place
A company selling high-temperature glazes searched "ceramics factory" on a B2B platform, exported a contact list, and started calling. After two weeks, conversions were almost zero. The post-mortem found that nearly half the names were branded sanitaryware distributors buying finished toilet bowls, not glaze; another batch were small relabeling dealers with no kiln line at all — glaze was meaningless to them. Two weeks of sales time, calculated at 25,000 RMB per person-month, was not a cheap mistake.
The ceramics and sanitaryware sector has many types of upstream suppliers: those selling glaze, pigment, and kaolin; those selling roller kilns and tile-press machines; those selling inkjet-printing equipment and inks; those selling smart-toilet electronic components (seat covers, solenoid valves, sensors). Each product type faces a different target factory profile, but they all share one core challenge — the hardest part of prospecting is not that the industry is fragmented; it is that real factories, traders, and brand owners are all mixed together, and distinguishing them by eye is nearly impossible.
China's total ceramic-tile output in 2024 reached 5.91 billion square meters, making the architectural ceramics market enormous (Ceramics Industry Information Network, 2024). In sanitaryware, dual policy pressure from water-efficiency certification and CCC mandatory standards is driving a concentrated wave of production-line upgrades and procurement windows. This timing is an opportunity for upstream sales — but only if you find the right targets first.
What These Factories Actually Look Like
Highly Clustered by Region — Sweeping Clusters Is the Most Efficient Play
Ceramics and sanitaryware has a trait relatively rare in Chinese manufacturing: production capacity is concentrated in a handful of clusters, not dispersed nationwide. This makes "following the cluster" the most efficient approach for upstream sales — instead of casting a national net, deep-working a few core clusters can cover the vast majority of genuine-production-line target factories.
Foshan is China's premier architectural-ceramics hub. As of end-2024, Foshan had 27 architectural ceramics producers, 138 production lines, and daily capacity of 1.728 million square meters; Guangdong province accounts for roughly 26% of national capacity (Ceramics Industry Information Network, 2024). The enterprise count looks modest, but each company runs large-scale lines with substantial procurement volumes for glaze, kiln consumables, and inkjet inks.
Chaozhou is the core cluster for sanitaryware ceramics. Chao'an Guxiang Township is known as "China's No. 1 Sanitary Ceramics Township," with sanitaryware output accounting for roughly one-third of the national total (China Daily Guangdong Bureau, 2024). Factories here focus on toilet bowls and washbasins; smart-bathroom upgrades are driving rising procurement of electronic components and new-generation glazes.
Zibo is Shandong's principal architectural ceramics cluster, focused on industrial and low-price engineering tiles. Local kiln and glaze companies hold a home-turf advantage; outside suppliers must offer clear differentiation on price or service.
Jingdezhen and Jiangxi's Gao'an and Fengcheng clusters specialize in mid-to-high-end ceramics, with some factories showing strong procurement appetite for artistic glazes and premium sanitaryware lines. Fujian's Jinjiang and Dehua focus on craft ceramics and export factories, with production configurations that differ markedly from mainland architectural ceramics clusters.
For glaze and kiln-equipment suppliers, Foshan and Chaozhou are the two highest-priority clusters: concentrated capacity, large factory scale, and reliable procurement volume.
Real Factory vs. Trader — The Kiln Is the Hard Line
OEM and relabeling are pervasive in ceramics and sanitaryware. Large numbers of "branded sanitaryware" companies handle only design and sales, sourcing toilet-bowl blanks from Chaozhou factories and shipping them under their own brand. Many online stores that claim "direct from factory" are backed by wholesale market stalls rather than their own production lines.
There is only one core criterion for identifying a real factory: does it have kilns and press-machine production lines?
A genuine ceramics factory — architectural type — will have roller kilns (often tens to over a hundred metres long) and hydraulic tile-press machines. Sanitaryware factories will have tunnel kilns or shuttle kilns plus slip-casting lines. These assets are costly to build, occupy large footprints, and cannot be hidden in a warehouse. Traders and brand owners, even if their business registration says "ceramics manufacturing," will have only warehouses and showrooms on site.
A second verification point is the production-site address on certifications. Both the Water Efficiency Label certificate for toilet bowls (GB 25502 water-efficiency grade) and the CCC mandatory certification certificate (mandatory from 1 July 2025) state the production-plant address — cross-checking whether that address matches the registered business address is a quick shortcut. Where a brand owner commissions OEM production, the certificate will carry the OEM factory's address. No certificate at all almost certainly means no in-house production line.
Three Steps to Find Ceramics & Sanitaryware Factory Customers
Step 1: Match Your Product to a Cluster, Then Build a Candidate List Within That Cluster
The priority cluster differs depending on what you sell.
Glaze and pigment sellers: Foshan factories run large-scale, stable-volume operations and are the primary battlefield; Chao'an Guxiang Township's sanitaryware factories have seen consistently growing procurement demand for functional glazes (anti-fouling, anti-slip, antibacterial) in recent years.
Roller-kiln and tile-press machine vendors: Foshan, Zibo, and Gao'an are the three main markets — factory scale is concentrated and upgrade cycles are trackable.
Inkjet-printing equipment and ink sellers: Foshan's large architectural ceramics factories have broadly completed their first-generation inkjet-line rollouts and are now entering the upgrade-and-replacement cycle, alongside slab-line expansion, making them the primary source of incremental equipment and ink demand.
Smart-toilet electronic component suppliers (seat covers, control boards, solenoid valves, sensors): Chao'an Guxiang Township is the most concentrated target cluster, currently undergoing a product-structure shift from standard toilet bowls to smart sanitaryware.
Once you have fixed your cluster, pull a candidate factory list within it. The most important thing to avoid at this stage is using keyword search to generate the list — searching "Chaozhou ceramics factory" returns results where traders and brand owners outnumber real factories.
Step 2: Use Industry-Specific Signals to Identify Factories That Are Actively Procuring
The ceramics and sanitaryware sector has several high-value procurement windows where upstream purchasing demand spikes:
Kiln upgrades and new-line construction. In early 2024, more than 45 new or upgraded architectural ceramics production lines were fired up nationally (architectural ceramics industry statistics, 2024). Each new line corresponds to a concentrated procurement burst for glaze, refractory materials, kiln ancillary equipment, and inkjet inks. Monitoring line-firing announcements and local government capacity filings is key to positioning early.
Slab-line expansion. Slabs — oversized ceramic panels, typically 1,600 mm × 3,200 mm and above — are the main growth segment in architectural ceramics in recent years. Slab lines require higher press tonnage, different kiln parameters, and more demanding glaze formulations than standard tiles, making them a high-value procurement window for relevant suppliers.
CCC mandatory certification compliance. CCC mandatory certification for smart toilets takes effect 1 July 2025; uncertified products may not be sold in the Chinese market and face fines of up to 200,000 RMB (policy driven by the State Administration for Market Regulation). The compliance window ahead of the deadline (2024–2025) has already driven large numbers of Chaozhou sanitaryware factories to procure specification-compliant electronic components and replace solenoid-valve and sensor models. This is one of the strongest procurement signals for electronic-component suppliers.
GB 25502 water-efficiency grade upgrades. The toilet-bowl water-efficiency standard GB 25502-2017 defines three efficiency grades; Grade 2 is the water-saving product certification baseline and Grade 3 is the market-access floor. When factories apply for or upgrade their Water Efficiency Label, they typically need to adjust components in their water-control systems — a natural entry point for valve and sensor suppliers.
Attending the Foshan Ceramic Expo / Smart Sanitaryware Exhibition. The Foshan Ceramic Expo (held at China Ceramics City) and the Chao'an Smart Sanitaryware Industry Summit are venues where factories publicly display their products and production-line status. Exhibiting factories have confirmed live production lines and tend to have relatively active procurement budgets around show dates.
Hiring records. Job postings for roller-kiln operators, slip-casters, glaze-application workers, and toilet-bowl inspectors are real-time signals that a production line is running and has expansion intent; postings predominantly for sales consultants or brand-promotion roles typically indicate a brand owner or trader.
Step 3: Use Tianxia Gongchang to Confirm Real Factories and Export an Actionable List
Steps 1 and 2 narrow the field. Step 3 requires a tool capable of distinguishing real factories from traders — serving as a final filter before you export your list.
Open Tianxia Gongchang, select "Architectural Ceramics" or "Sanitary Ceramics / Sanitaryware" under industry classification, layer on the production cluster (Foshan / Chaozhou Chao'an / Zibo / Jingdezhen), set an enterprise-scale range, and export the candidate list.
Tianxia Gongchang covers 4.8 million real manufacturing enterprises in China and has run a factory-identification assessment on every entity in the ceramics and sanitaryware segment — each record in the list is flagged for whether it is a genuine manufacturing entity, so traders, branded distributors, and shell registrations with no production lines are filtered out at this step. Log in to Tianxia Gongchang, filter by industry plus cluster, and check how many entries in your initial list are flagged as "non-factory entity" — in the Foshan architectural ceramics and Chaozhou sanitaryware clusters, the proportion of brand owners and traders mixed into the raw results routinely exceeds the expectations of first-time users.
Once the list is confirmed, layer in the procurement signals from Step 2 (new-line construction, CCC compliance, Ceramic Expo participation) to set priority order: factories with confirmed upgrade or certification activity go first; those with hiring-and-expansion signals in the past six months are next; the rest enter a regular nurture sequence.
How to Use Tianxia Gongchang for the Ceramics & Sanitaryware Sector
Factory-Identification Baseline: Whether a Production Line Exists — One Search Tells You
Tianxia Gongchang's core capability is real-manufacturing-entity identification, not a straightforward enterprise-database lookup. All 4.8 million enterprises covered have gone through factory-attribute verification, separating entities with genuine factory buildings, production lines, and manufacturing capacity from brand owners, traders, market stalls, and pure distributors.
This matters especially in ceramics and sanitaryware. Enterprise-lookup tools of the Qichacha type can pull up the registration record for "Chaozhou XX Sanitaryware Co., Ltd." but cannot tell you whether that company has its own tunnel kiln firing toilet bowls or is simply displaying samples at a market-stall unit and forwarding orders. On 1688, the "factory store" tag likewise covers large numbers of intermediaries with no in-house production lines. Tianxia Gongchang has built an independent judgment mechanism for factory identification, so glaze and kiln-equipment sales teams stand on solid ground at the very first step of list-building — and do not burn visit capacity on traders with no procurement need.
Ceramics & Sanitaryware — Recommended Filter Sequence
When filtering ceramics and sanitaryware in Tianxia Gongchang, apply conditions in the following order:
- Industry classification: Architectural Ceramics (subdivide: ceramic tiles / slabs / art ceramics) / Sanitary Ceramics (toilet bowls / washbasins / bathtubs) / Smart Sanitaryware
- Cluster / region: Foshan, Chaozhou Chao'an, Zibo, Jingdezhen, Gao'an — prioritise based on your own sales coverage
- Scale range: Large architectural ceramics factories (Foshan cluster tends toward large scale) / Mid-size sanitaryware factories (Chao'an Guxiang Township focus)
- Factory-attribute filter: Show only records identified as genuine manufacturing entities
- Export the list, then apply a second-pass priority sort using upgrade activity, CCC certification status, and Ceramic Expo participation from Step 2
Tianxia Gongchang integrates cluster selection, industry subdivision, and factory-attribute filtering in a single interface — glaze sales teams do not need to cross-reference multiple platforms; they get a directly actionable factory list ready for follow-up.

Four Questions to Verify a Real Factory
- Does it have roller kilns / tunnel kilns / tile-press machines or equivalent primary production equipment? (Ask for factory-floor photos or a production-line video.)
- Does the "production-plant address" on its CCC certificate or Water Efficiency Label match its registered business address?
- Do its job postings include kiln operators, glaze-application workers, slip-casters, or other front-line production roles?
- Can it provide the original water-efficiency test report or CCC certificate number? (Verifiable on the CNCA website.)
The Cluster Is Your Map — Work One Route and the List Writes Itself
The hard part of selling into ceramics and sanitaryware is not too few target customers; it is that clusters are so concentrated and real factories so hard to tell apart from fakes — and it is precisely these two factors that make the "follow the cluster" approach more effective here than in almost any other industry. Foshan's 138 architectural ceramics lines and Chao'an Guxiang Township's one-third share of national sanitaryware output together form the densest concentration of genuine ceramics and sanitaryware factories in China. Working one route thoroughly through one cluster yields a far higher hit rate than casting a national net.
Tianxia Gongchang combines cluster targeting with factory-attribute identification in a single workflow — glaze and kiln-equipment sales teams do not need to verify business-card by business-card at trade shows whether the person across from them actually has a production line running. Filter by cluster in Tianxia Gongchang, apply the factory filter, export the list, and invest the time saved in factories where kilns are genuinely in operation. That is the right way to build a lead list for upstream sales in this industry.
