Start with the four decisions that change the tender outcome
For NGO procurement, the blanket is not just a textile item. It is also a freight unit, a kit component, and an inspected humanitarian supply. The first decision is fabric weight basis. The second is finished size. The third is unit packing and carton density. The fourth is inspection logic. If any one of those is left vague, suppliers can quote against different assumptions and the tender stops being commercially comparable.
For this category, buyers should write the fabric line as 200gsm finished fabric basis weight, not greige weight. In most China sourcing programmes for fleece blankets, suppliers quote fleece GSM on the finished fabric because brushing, dyeing, heat-setting, and anti-pilling finishing change mass and handfeel. Some mills still discuss greige knitting weight internally, but that is not a reliable tender basis. If one supplier quotes 200gsm finished and another quotes 200gsm greige, the finished blankets will not be equivalent.
The packing decision matters just as much as the textile decision. A 150 x 200 cm fleece blanket at 200gsm can often be packed either loose-folded or vacuum-compressed, and the freight outcome is materially different. But higher compression raises risk of nap crush, hard fold memory, and poor first-use appearance. A tender should therefore define not only pack style but compressed dimensions, recovery window, and acceptance standard after opening.
The inspection decision must go beyond “AQL 2.5”. That phrase alone is incomplete. A usable scheme should name ISO 2859-1 or ANSI/ASQ Z1.4, state general inspection level, define AQL by defect class, and list actual defect examples. Without that, the buyer, supplier, and third-party inspector may all apply different acceptance logic to the same lot.
Define 200gsm with the exact test method and conditioning
The clean procurement wording is: 100% polyester polar fleece, 200gsm finished basis weight, measured on finished fabric after brushing, dyeing, heat-setting, and final conditioning. If recycled content is required, state it separately as a documentary claim and do not let it replace the physical construction description. For example: 100% polyester polar fleece made from virgin polyester, or recycled polyester with valid chain-of-custody documents where claimed.
For fleece in this weight band, the most common construction in the market is warp or circular knitted polyester fleece made from fine denier filament yarns that are brushed and sheared. For better control, specify yarn family rather than broad marketing language. A workable line is: polyester filament-based fleece, typically 75D/72F to 150D/144F equivalent filament input, low-lint anti-pilling finish. If a recycled option is accepted, ask the supplier to declare whether the fleece face is filament-based, spun staple, or blended construction, because pilling and lint behaviour differ.
Basis weight should be tested to ISO 3801 or ASTM D3776, and the PO should nominate one method so the lot is judged on a single basis. Conditioning should be at standard textile atmosphere, typically 20 +/- 2 degrees C and 65 +/- 4% RH, for not less than 24 hours before testing unless the nominated standard states otherwise. Sampling should be from finished production fabric, not lab swatches, with a practical plan such as 5 specimens per colour lot taken across the fabric width and across the beginning, middle, and end of the run.
To avoid arguments on small accessories affecting mass, state that GSM is measured on fabric specimens cut away from labels, seams, and edge finishes. Acceptance can then be written clearly: lot average 200gsm nominal, allowable range 194-210gsm; no individual specimen below 190gsm or above 214gsm. That is stricter than casual market language, but it gives a tender team and inspector a defensible decision rule.
Do not turn warmth into a contractual claim unless it is tested
A 200gsm polar fleece emergency blanket is commonly used for relief distribution, transit support, temporary shelters, clinics, and basic household coverage. It is lighter and easier to freight than 230gsm to 250gsm fleece, while giving better opacity and hand than many 160gsm to 180gsm offers. That is a sourcing observation, not a thermal guarantee.
Buyers should avoid contractual statements such as “suitable for 15-20 degrees C” unless the programme has validated a thermal method and use case. Fleece warmth is not standardised by GSM alone. Fibre type, pile height, air permeability, brushing intensity, moisture state, garment layering, wind exposure, and user age all change field performance. If thermal performance matters, specify a defined insulation or thermal resistance method and accept that testing adds cost and development time.
For standard NGO blanket tenders, it is safer to contract the physical construction and durability parameters rather than informal warmth language. Ask for basis weight, finished dimensions, pile uniformity, pilling resistance, colourfastness, dimensional change, and pack recovery. If a buyer needs a warmer product, the more defensible route is to move the specification upward to a heavier fleece or a filled construction rather than writing soft language around 200gsm.
For a lighter relief option, see 180gsm polyester fleece blankets with overlocked edges for disaster relief. For shade-stable fleece programmes where outdoor light exposure matters, see solution dyed 220gsm polyester fleece blankets.
Build the specification around measurable textile performance
A tender-ready specification should state at minimum: composition, yarn construction, brushing and shearing finish, anti-pilling finish, finished size, edge finish, colour standard, care label, unit packing, carton packing, inspection scheme, and test thresholds. Words such as soft, warm, premium, or heavy-duty do not control production.
A practical baseline blanket body is: 100% polyester polar fleece, filament-based knit, anti-pilling finished, brushed and sheared, 200gsm finished basis weight, finished size 150 x 200 cm, colour as approved standard, one-piece cut blanket with overlocked perimeter or folded hemmed perimeter. If cut-and-sewn edges are allowed, add measurable sewing requirements: overlock 3-thread or 4-thread, stitch density 8-11 SPI for hemmed seams, balanced tension, no skipped stitches, no seam grin, no broken yarns, and seam allowance 10-15 mm where applicable.
Durability comments should be tied to tests. If overlocked edge construction is used, require edge integrity after laundering with no seam opening greater than 10 mm and no continuous thread break along more than 50 mm of perimeter. If folded hem construction is used, require no seam slippage or edge roping visible at normal use distance after washing. Where buyers want a stronger sewn construction, add seam strength testing to ASTM D1683 or fabric grab strength to ISO 13934-1 on the body fabric, especially for blankets that will be repeatedly laundered in institutions.
If single-side and double-side brushing are both commercially acceptable, do not leave it as preference language. State the procurement rationale. For example: single-side brushed fleece may be specified to reduce cost and pack bulk; double-side brushed fleece may be specified only if approved handfeel, pilling, and lint results are maintained. That keeps the decision measurable instead of subjective.
Use exact pass-fail thresholds for pilling, fastness, and dimensional change
If the article or PO says the blanket is anti-pilling, the tender should define how that is judged. A workable baseline for emergency blanket fleece is ISO 12945-2 Martindale pilling, tested on conditioned finished fabric, with the face side and reverse side both assessed after 2,000 cycles. Pass criterion: minimum grade 3.5 on both face and reverse; no specimen below grade 3. If the programme expects repeated washing and extended reuse, tighten that to grade 3.5 after 5,000 cycles.
For wash fastness, use ISO 105-C06. A common tender setup is test condition A1S or equivalent agreed procedure, with assessment after 1 laundering cycle. Pass criterion for dyed solid fleece can be written as: colour change minimum grade 4; staining on adjacent multifibre strip minimum grade 3-4 for cotton, polyester, nylon, acrylic, wool, and acetate. If the programme requires multiple wash durability, add a second line after 5 cycles with colour change minimum 3-4.
For rubbing fastness, use ISO 105-X12 on the finished face side. Pass criterion: dry rubbing minimum grade 4, wet rubbing minimum grade 3. Dark shades, especially navy, red, and black, should be checked carefully because they are the common dispute colours in field tenders.
For dimensional stability, use ISO 6330 for home laundering procedure and ISO 5077 for measuring dimensional change. State specimen orientation explicitly: one set in the lengthwise wale direction and one set in the crosswise course direction. A practical baseline after 1 wash and line dry or tumble procedure as agreed is maximum dimensional change +/-3% in length and +/-3% in width. If the buyer wants a stricter reused-blanket programme, add a 3-cycle criterion of maximum +/-4%. This closes the common loophole where a supplier passes only in one fabric direction or after a single gentle cycle not representative of actual use.
Control size, colour, and shade with the right reference standard
Dimension disputes usually come from measuring the wrong thing. For NGO tenders, specify finished size after conditioning, not cut size. Example: finished size 150 x 200 cm, measured laid flat after conditioning at 20 +/- 2 degrees C and 65 +/- 4% RH, tolerance +/-2 cm each direction. If hemmed edges consume more turn-in than overlocked edges, that does not change the finished-size obligation.
Colour approval should also be formalised. The safest method is sealed lab dip approval before bulk dyeing, then production approval against either the sealed lab dip or a sealed approval blanket. Shade should be assessed under at least D65 and TL84 lighting conditions, plus visual check for metamerism where colour sensitivity is high. If the buyer uses instrumental colour control, write a tolerance such as Delta E CMC or Delta E 2000 not exceeding 1.0-1.5 against the approved standard, with the exact formula stated in the colour approval sheet.
Do not rely only on carton-to-carton visual checks. Ask the supplier to keep shade continuity by production lot and carton range, then mark each carton with colour code, lot number, and production date. This reduces mixed-shade complaints at destination, especially on dark relief colours where adjacent tone differences become obvious in stacked distribution.
A common supplier loophole is approval against one standard in the lab and another during final inspection. Corrective wording is simple: bulk shipment shade shall match sealed buyer-approved standard; internal mill standard cannot replace sealed approval reference.
Inspection needs a named scheme, defect classes, and examples
For finished blanket inspection, specify ISO 2859-1 single sampling, normal inspection, General Inspection Level II, unless the buyer has a different house standard. If the lot is unusually high risk or first-order, the buyer may move to tightened inspection, but that should be stated before production or before final inspection booking.
A practical acceptance structure is: Critical defects AQL 0.0, Major defects AQL 2.5, Minor defects AQL 4.0. Critical defects include wrong fibre content where regulated, sharp contamination, mould, severe odour, needle fragments, or gross mislabelling that creates a safety or compliance issue. Major defects include finished size outside tolerance, GSM below minimum, major holes, oil stains over agreed visibility threshold, open seams, severe shade variation, incorrect carton quantity, failed vacuum recovery, or incorrect care/content label. Minor defects include slight sewing waviness, small loose threads, minor soil that is removable, or slight fold impression within agreed recovery limit.
State actual inspection points. For example: dimensions on 100% of sampled pieces; weight by fabric specimen or agreed unit-weight cross-check; workmanship visual check under adequate lighting; shade by comparison to sealed standard; packing count; carton marks; and compression pack dimensions. If vacuum-packed units are supplied, include opening of at least 3 sampled units per inspected lot for recovery assessment at agreed intervals.
If the buyer wants extra discipline, add a defect photo appendix to the PO or quality manual. That is often more useful than broad wording because factories and third-party inspectors then score the same issue consistently. For broader QC practice, see blanket quality control inspection and AQL 2.5 inspection checklist for 200gsm fleece blankets.
Vacuum compression needs dimensions, recovery criteria, and carton data
If the tender promises carton planning and compression control, it needs numbers. For a common 150 x 200 cm, 200gsm fleece blanket with overlocked edge, the finished unit weight is often in the range of 0.62-0.70 kg net per piece depending on actual cut size, pile density, label package, and edge construction. A reasonable packed assumption for vacuum-compressed single units is one blanket per PE bag, then master carton packing of 15-20 pcs per export carton depending on target carton strength and handling limits.
A workable carton example for tender planning is 15 pcs/carton, carton size about 58 x 40 x 45 cm, net weight about 9.3-10.5 kg, gross weight about 10.0-11.5 kg. If the buyer pushes to 20 pcs/carton, dimensions may move closer to 60 x 42 x 55 cm and gross weight may approach manual handling limits in some destinations. Do not issue these as universal constants; write them as approved packing assumptions subject to PPS confirmation.
Compression should be written as a dimensional control, not just “vacuum packed”. Example clause: each blanket folded and vacuum-packed to 38 x 32 cm +/-2 cm, finished packed thickness 4-6 cm, bag seal intact, no air leakage after 24 hours at ambient storage. Recovery requirement should then be tested by opening sampled units and laying them flat. Practical acceptance can read: after opening, blanket shall recover to at least 90% of original measured loose thickness within 30 minutes and 95% within 24 hours at 20-25 degrees C; no permanent crushed band wider than 15 mm visible at 1 metre under normal lighting.
If the programme prefers loose fold rather than vacuum pack, say so explicitly. A common supplier loophole is to change fold style late in production to fit a target carton count. Corrective wording: fold pattern, unit bag type, and carton count are controlled characteristics and may not be changed without written buyer approval.
Add packaging compliance details that NGO tenders usually miss
Relief tenders often focus on the blanket but forget packaging compliance. That creates avoidable claims. The PO should state whether individual polybag packing is allowed, prohibited, or optional. If allowed, specify minimum two ventilation holes where required by the buyer's packaging policy, and specify bag thickness range if relevant. If not allowed for environmental or distribution reasons, write no individual retail polybag; units bundled in master carton with moisture barrier liner.
Export cartons should be specified with board grade or burst strength appropriate to route and pallet stacking. A practical baseline for sea freight is a 5-ply export carton with suitable compression strength for stacking, plus internal moisture protection such as a carton liner or pallet top cover where container humidity risk is material. For humid routes or monsoon discharge seasons, ask for desiccant use or pallet stretch-wrap with top cap, especially if the goods may sit in open warehouses.
Carton marks should be standardised. A useful format includes: consignee, PO number, item description, colour, size, quantity per carton, carton number sequence, gross weight, net weight, carton dimensions, country of origin, and any project code required by the NGO. If mixed lots are not allowed, write one colour/one production lot per carton unless buyer-approved.
Palletisation should also be written if required: for example fumigation-compliant or plastic pallet as destination requires, maximum pallet height 1.6 m, no pallet overhang, stretch-wrap plus top sheet, corner boards if stacked two-high. Without this, suppliers may optimise only for factory loading rather than inland handling at destination.
Use a procurement table so the PO cannot drift
A short technical schedule inside the PO usually works better than long prose. Buyers can adapt the following fields directly into tender documents or purchase orders.
Sample procurement table
Material: 100% polyester polar fleece, filament-based, anti-pilling finish, 200gsm finished fabric basis weight tested to ISO 3801 or ASTM D3776.
Size: 150 x 200 cm finished size after conditioning, tolerance +/-2 cm each direction.
Edge finish: 3-thread or 4-thread overlock, or folded hem 8-11 SPI if approved; no skipped stitches or seam opening beyond agreed limit.
Label: woven or printed care/content label, placement per approved artwork, tolerance +/-10 mm.
Packing: one piece folded and vacuum-packed or loose-packed as approved; bag vent holes yes/no as specified; no air leakage after 24 hours for vacuum pack.
Carton: 15 pcs or approved count; export carton dimensions and GW/NW per PPS; moisture barrier liner required.
Carton marks: consignee, PO, item code, colour, size, qty, carton number, GW/NW, dimensions, COO, project code.
Tests: ISO 12945-2 pilling grade >=3.5 at 2,000 cycles; ISO 105-C06 colour change >=4 and staining >=3-4; ISO 105-X12 dry >=4 wet >=3; ISO 6330 plus ISO 5077 dimensional change <=+/-3% after 1 cycle.
Tolerances: GSM 194-210 lot average range, no individual specimen below 190gsm; size +/-2 cm; shade to sealed standard under D65 and TL84.
Inspection: ISO 2859-1, General Level II, Critical 0.0 / Major 2.5 / Minor 4.0.
Documents before shipment: approved lab dips, PPS approval, test reports, packing list, carton spec, inspection report, and shipping marks approval.
This kind of table removes room for selective interpretation. It also makes it easier for freight teams, QA teams, and field distribution teams to work from the same controlled document.
Include a PO clause, document package, and common loophole corrections
A usable PO clause can be concise. Example: Supply 200gsm finished polyester polar fleece emergency blankets, finished size 150 x 200 cm +/-2 cm, colour to sealed buyer standard, anti-pilling finish, packed per approved PPS. Fabric basis weight tested on conditioned finished fabric to ISO 3801 or ASTM D3776 shall average 194-210gsm with no individual specimen below 190gsm. Final goods shall pass ISO 12945-2 pilling min 3.5 at 2,000 cycles, ISO 105-C06 colour change min 4 and staining min 3-4, ISO 105-X12 dry min 4 wet min 3, ISO 6330 plus ISO 5077 dimensional change max +/-3% after 1 cycle. Inspection to ISO 2859-1 Level II, AQL critical 0.0 major 2.5 minor 4.0. No change to material, finish, fold, unit pack, carton count, or production lot without written buyer approval.
Pre-shipment document package should be listed, not implied. A practical minimum is: approved material submission sheet; approved lab dip or sealed shade standard; pre-production sample approval; pre-shipment sample approval; test reports to the nominated standards; inline and final inspection reports; final packing list; carton mark artwork; carton specification sheet; weight and measure sheet; declaration of fibre content; recycled-content documents where claimed; and commercial documents matching shipment marks and quantities.
Common supplier loopholes are predictable. One is quoting finished size but cutting to that size before sewing or overlocking, which reduces delivered dimensions. Corrective wording: all dimensions refer to finished delivered blanket after full processing and edge finishing. Another is using blanket unit weight instead of fabric GSM, which can hide an undersized blanket. Corrective wording: fabric basis weight and finished dimensions are separate acceptance criteria; compliance with one does not waive the other. A third is testing only salesman swatches rather than bulk. Corrective wording: all acceptance tests shall be taken from bulk production lot and, where relevant, from packed finished goods.

Frequently asked
Should NGO tenders specify 200gsm on greige or finished fleece? Specify 200gsm on finished fabric. In the export fleece blanket trade, finished GSM is the more reliable tender basis because brushing, dyeing, shearing, and heat-setting change mass and appearance. Greige knitting weight is useful for internal mill control but should not be used as the acceptance basis for delivered blankets unless the buyer has a very specific development reason.
What is a realistic test package for 200gsm polar fleece emergency blankets? A practical baseline is GSM to ISO 3801 or ASTM D3776; pilling to ISO 12945-2 with minimum grade 3.5 after 2,000 cycles; wash fastness to ISO 105-C06 with colour change minimum grade 4 and staining minimum grade 3-4; rubbing fastness to ISO 105-X12 with dry minimum grade 4 and wet minimum grade 3; dimensional change to ISO 6330 plus ISO 5077 at maximum +/-3% after 1 wash cycle. Buyers with repeated-use programmes may add multi-cycle laundering and seam strength checks.
Is AQL 2.5 enough for blanket inspection? No. AQL 2.5 without a named inspection standard and defect classes is incomplete. A stronger setup is ISO 2859-1 or ANSI/ASQ Z1.4, General Inspection Level II, with Critical defects at AQL 0.0, Major at 2.5, and Minor at 4.0, plus written examples such as holes, oil stains, wrong size, open seams, shade variation, and packing errors.
Can 200gsm fleece be marketed as suitable for a certain temperature range? Not safely as a contractual claim unless the buyer and supplier agree a thermal test method and use case. GSM alone does not define warmth. Fleece warmth depends on loft, air permeability, moisture condition, layering, wind, and user factors. For tenders, control measurable textile properties rather than informal temperature statements.
What carton pack is typical for a 150 x 200 cm 200gsm fleece emergency blanket? A common export assumption is 15 pieces per carton at roughly 58 x 40 x 45 cm, with net weight around 9.3-10.5 kg and gross weight around 10.0-11.5 kg, depending on edge finish, label package, and whether the units are vacuum packed. Heavier carton counts are possible but can create handling and recovery issues, so they should be confirmed by approved pre-shipment packing data.
What pre-shipment documents should the buyer require? At minimum: approved lab dips or sealed shade standard, pre-production sample approval, pre-shipment sample approval, bulk test reports, inspection report, final packing list, carton specification, shipping mark approval, fibre content declaration, and any recycled-content chain-of-custody documents if those claims are part of the order. Without this package, final disputes are harder to resolve because the approval trail is incomplete.
