China’s established XPS supply chain gives importers and fabricators a strong sourcing base for insulation boards, processed cores and custom dimensions. Banarta connects that product choice with bulk purchasing requirements. A clear board schedule is how you turn manufacturing breadth into comparable quotations and a repeatable supply plan.
Use China’s product range to improve the purchasing plan
Group boards by their actual job: standard XPS insulation boards, slotted fabrication cores or another defined use. For a drawing-controlled or custom-label repeat-order brief, compare the OEM / ODM XPS supply requirements. Then separate the required grade, dimensions, edge profile and surface finish. This gives the supplier room to propose a suitable production format while keeping the performance requirement fixed.
For bulky boards, compare the purchasing cost per usable unit alongside packed volume. A lower piece price can be offset by a different thickness, cutting yield or pallet arrangement. Request the pack count, outside dimensions and gross weight for the proposed mix, then compare transport on the same basis. Use the board quantity and packing-volume guide to structure the calculation.
For repeat supply, submit the first-order quantity and expected replenishment separately. Agree which sample, grade documentation and specification revision the next order will follow. China’s depth of manufacturing and processing options is most useful when purchasing teams keep that specification consistent across quotations and reorders.
Explore XPS insulation boards supplied from China and include any cutting, groove, edge or packaging requirements in the same enquiry.
Download the bulk enquiry worksheet
Download the bulk enquiry worksheet (Excel .xlsx). Use one line per grade, size and finish. State whether the requested quantity is in pieces, m² or m³, and identify the performance documents needed for the proposed application.
Complete the Enquiry and Order items tabs, then email the workbook and supporting files to Tina at Banarta. Available configurations, minimum quantities, price and delivery timing are confirmed in the quotation.
Review a supplier’s quotation
After completing the enquiry and order items, use the Supplier response tab to record one supplier’s quoted terms, deviations and supporting references. Identify each configuration by its original Line number and update the manual check date when reviewing the quote.

The prompts flag missing responses and dates; purchasing decisions still require buyer review.
Use a board schedule
| RFQ field | What to include |
|---|---|
| Application | Floor, wall, roof or fabrication; attach the relevant section |
| Product requirement | Specified grade or performance requirement, with test basis where defined |
| Dimensions | Length × width × thickness; tolerances and edge profile |
| Surface | Skin, roughened surface, grooves or facing requirements |
| Quantity | Pieces and/or square metres, with cutting allowance identified |
| Delivery | Destination, delivery basis and required arrival window |
| Documents | Required datasheet, test reports and traceable product identification |
If you have not selected a grade, say so. Ask for a proposed configuration against the requirements rather than writing an assumed value into the order. Keep technical acceptance separate from a supplier’s ability to quote a size.

Ask for documents that match the offer
Check whether a report describes the material being offered, its thickness or relevant configuration, and the stated test conditions. A brochure covering a broad range is not the same as evidence for every combination. If the project requires a fire classification, request the named classification system and applicable report rather than accepting an unexplained letter or grade.
Agree the sample and acceptance record
Give the sample a reference and date. Record dimensions, appearance and the characteristics it is intended to represent. A small sample can support visual and dimensional checks; it cannot establish all installed performance. For machined boards, approve the drawing revision as well as the sample so that groove geometry and tolerances are not left to memory.
For bare cores that your workshop will laminate, use the XPS core thickness budget and first-piece record to compare the complete layer stack and agree individual measurement points before ordering.
Compare delivered cost and practical handling
- Ask how many pieces and square metres are in each pack.
- Confirm pack dimensions and weight for your unloading and storage arrangements.
- State which edges or surfaces need extra protection.
- Agree how quantities, damage and deviations will be recorded on receipt.
- Request separate confirmation of lead time, minimum quantity and any custom-processing conditions; do not assume standard terms.
Send this information when discussing Graphite XPS Foam Insulation Board. Ask the quotation to list any deviation explicitly. An offer that states its exceptions is easier to evaluate than a low price with an undefined specification.
Shortlist suppliers for the same order scope
Distributors, importers and project purchasing teams should compare an identified board configuration before comparing supplier prices. Banarta is a materials brand and supplier; ask which documents, sample arrangements and processing options apply to the offered grade. Do not treat a general company presentation as a specification for every board.
| Comparison item | Ask each supplier for |
|---|---|
| Material identity | Product reference and current grade-specific datasheet. |
| Repeat order control | How the approved specification, drawing revision and any substitutions will be identified. |
| Commercial scope | Same quantity, price unit, packing and named delivery basis. |
| Document gaps | An explicit list of requirements not yet supported or not included. |
Copy a bulk-order enquiry
Product link: [reference]. Application and country: [details]. Board dimensions and edge/surface: [schedule]. Required grade or performance: [requirement and test basis]. Quantity: [pieces per size and area]. Custom processing: [drawing revision or none]. Documents: [list]. Packing and labels: [requirements]. Destination and required arrival: [details]. Please identify exceptions and quote samples, minimum order, lead time and quotation validity separately.
Compare cost using consistent units. Board area in m² equals length in metres × width in metres; volume equals area × thickness in metres. State whether a price covers a board, m², m³ or pack. Keep freight and additional processing visible rather than comparing different units as though they were equivalent.
Worked example: board price versus volume price
Illustrative figures only — not a Banarta quotation or stock-size confirmation. Assume two technically approved offers cover the same 200 boards, each nominally 1.2 × 0.6 × 0.05 m. Gross area is 0.72 m² per board and volume is 0.036 m³. The order totals 144 m² or 7.2 m³; installed coverage and cutting losses are separate.
| Comparison | Offer A | Offer B |
|---|---|---|
| Quoted board rate, USD | $4.32 per board | $110 per m³ |
| Board-only cost per m² | $4.32 ÷ 0.72 = $6.00 | $110 × 0.05 = $5.50 |
| Boards for the same 200-piece order | $864 | $792 |
| Packing and transport for the same agreed scope | $40 | $160 |
| Total for this quoted scope | $904 | $952 |
| Total divided by 144 m² | $6.28 per m² | $6.61 per m² |
Offer B has the lower board-only rate, but Offer A has the lower total for the scope shown. This example excludes taxes, duties, installation and any charge outside the stated scope; it is not a landed-cost or installed-cost estimate. In an actual comparison, record every inclusion, exclusion, currency and delivery point before choosing.
Use volume conversion only for an offer that is actually priced by nominal board volume. Do not apply it automatically to coated, faced, grooved or assembled products, where the quotation may use a different basis. Equal calculated cost does not establish equal grade, strength, thermal performance or suitability.
Browse the XPS insulation board supply range and use the thickness and grade guide if the specification is undecided. Send Banarta your board schedule.
