Buying partitions from China is not hard. Buying them <em>well</em> is harder, because the supplier landscape is opaque and most of what you read online is written by the platforms that sell listings.
Start with the distinction that matters most
The single most consequential thing to establish is whether you are talking to a manufacturer or a trading company. A large share of storefronts under partition categories on B2B platforms belong to trading companies. That is not automatically a problem — a good trading partner can manage quality control and shipping effectively — but it changes who is accountable, how much specification control you have, and how the price breaks down.
Indicators that point toward a real manufacturer:
- An independent company website that describes production, not just a catalogue. Look for process descriptions, equipment lists, or a factory tour section.
- A published factory address that resolves to an industrial area when you check it on a map.
- Production photographs showing panels being fabricated, rather than finished goods photographed in a showroom.
- Willingness to do a live video call from the production floor without extensive scheduling friction.
- Specific answers to specific questions. Ask what core material is used and why, how the track is fixed, what tolerance the panels are made to. A trading company will defer; a factory will answer.
None of these is conclusive alone. The most reliable test remains technical depth: ask about the panel construction, the sealing mechanism, and how the system handles deflection at height. Watch whether the answer is immediate and detailed.
Verify the certifications, not the claims
Certification is where the most expensive misunderstandings happen. A few distinctions worth internalising:
A test report is not a certificate
An acoustic rating should come with a report from a recognised laboratory that names the tested construction, the standard used, and the result. Ask for the report itself, not a certificate of conformity issued by the supplier. Check that the tested panel thickness and construction match what you are ordering — a report for a 100 mm panel does not cover a 65 mm panel.
Match the standard to your market
Fire performance standards differ by destination: EN 13501 and BS 476 in Europe and the UK, ASTM E84 in the United States, and various national equivalents elsewhere. A supplier who cannot tell you which standard their documentation refers to has probably never had it checked by a buyer who needed it.
ISO 9001 is about process, not product
ISO 9001 tells you something about the company's quality management system. It says nothing about whether a specific partition achieves a specific acoustic or fire rating. Treat it as a baseline indicator, not evidence of product performance.
Fix the specification before you compare prices
Quotations are only comparable if the specification is fixed. Send every shortlisted supplier the same brief, including:
- Product type and configuration — stacking, sliding, folding, or fixed
- Panel thickness and core material, or an explicit statement that it is open
- Required acoustic rating and the test standard it must meet
- Required fire rating and the standard
- Clear opening dimensions and clear height
- Finish specification, or a reference photograph
- Destination port and preferred Incoterm
- Required delivery window
A supplier who quotes without asking about several of these is quoting a standard product and will revise upward once the real requirement emerges. That revision is where project budgets break.
Ask for evidence of comparable projects
A total project count tells you very little. What you want is a reference in a comparable climate and building type — a hotel ballroom in a humid climate, a hospital operating theatre, an airport terminal with heavy traffic. Ask for project names you can verify independently.
Where a manufacturer publishes project cases with a verifiable source, we record them and they contribute to the Factory Score. Self-reported totals without a source are recorded as claims and do not score.
Understand what the Factory Score does and does not tell you
Factory Score on this directory is a transparency metric: it measures how much publicly verifiable information a company publishes. It is not a quality rating.
A capable manufacturer with a Chinese-only website and no English documentation will score low here — often lower than a polished trading company with a long certification list. Use the score to find companies whose data you can verify, then do the commercial diligence yourself. Read the scoring methodology for the full breakdown.
Before you place the order
- Get the drawing approval step in writing, and confirm who is responsible for dimensional errors in the approved drawing.
- Agree the inspection regime — third-party inspection, or at minimum a pre-shipment video walkthrough.
- Confirm the packing method for panels and hardware, and who bears risk for transit damage.
- Establish the tolerance for finish variation in writing, with a physical sample if the finish matters.
- Confirm the warranty terms and what happens if a component fails in service.
The short version
Fix the specification before you ask for prices. Verify certifications against the standard your market requires. Establish whether you are buying from a factory. Get a reference you can check. Everything else is negotiation.
Frequently asked questions
How do I know if a Chinese supplier is a real factory?+
Look for an independent company website that describes production rather than just listing products, a published factory address that resolves to an industrial area on a map, production photographs showing your product being made rather than finished goods in a showroom, and willingness to do a live video call from the production floor. No single indicator is conclusive — the most reliable check is asking detailed technical questions about panel construction and judging whether answers come quickly and specifically.
What certifications should a partition manufacturer have?+
It depends on your project. For fire performance, the relevant standards are typically EN 13501, BS 476 or ASTM E84 depending on your market. For acoustics, ask for a test report showing the acoustic rating (Rw or STC) for the specific panel construction you are buying. ISO 9001 is a management system certificate — useful but it says nothing about whether a specific panel achieves a specific rating.
Should I buy from a manufacturer or a trading company?+
Both can work. Buying directly from a manufacturer usually gives you more control over specification and customisation, and clearer accountability when something goes wrong. A good trading company can manage quality control, consolidate orders and handle documentation more efficiently than you can yourself. The important thing is knowing which you are dealing with, because it changes your negotiation position and who is responsible for defects.
What should I include in a quotation request?+
Product type and configuration, panel thickness and core material, required acoustic rating with the test standard, required fire rating with the standard, clear opening dimensions and height, finish specification or a reference image, destination port and preferred Incoterm, and required delivery window. Quotations are only comparable if the specification is fixed.
