1. Start With Fabric Construction, Not Only GSM
For a 280gsm flannel fleece throw, GSM is only the weight. It does not define loft, warmth, surface feel or pilling risk. A workable RFQ should state: 100% polyester knitted fleece, target 280gsm with production tolerance of +/-5%, finished size such as 130x170cm or 150x200cm with +/-2cm tolerance before wash, and dimensional change after one domestic wash no worse than about -3% length and -3% width when tested to an agreed ISO 6330 procedure.
Most flannel fleece at this weight is knitted from fine polyester filament yarn, commonly in the 75D to 150D range depending on the mill's machine set-up and target hand feel. A finer filament gives a smoother face and better drape; a coarser yarn can feel bulkier but may show harsher nap lines after brushing. Ask the mill to declare yarn denier, filament count if available, knit type, machine gauge and whether the greige fabric comes from one knitting lot or mixed stock.
Brushing is the main risk area. One-side brushed flannel is cleaner for packing and sheds less lint. Double-side brushed flannel feels softer but raises more fibre ends, which can increase pilling and loose fibre during first unpacking. For a retail throw, a practical target is even nap direction, no bald bands, no hard crease lines from overfeeding, and a finished pile height that stays consistent across the panel. Over-brushing weakens the ground knit; under-brushing leaves a patchy hand. Put a sealed pre-production sample into the PO and use it as the bulk hand-feel standard.
For testing, set pilling to ISO 12945-2, with a realistic target such as grade 3-4 or better after the agreed number of rubs. Set rubbing fastness to ISO 105-X12, normally grade 4 dry and 3-4 wet or better for medium and dark shades. Set wash fastness to ISO 105-C06, usually grade 4 or better for colour change and staining on common adjacent fabrics. These targets are reachable for disperse-dyed polyester, but dark navy, black, burgundy and saturated red still need lab confirmation before shipment.

2. Treat UK Fire Scope Carefully
Do not write a PO that says every loose polyester blanket sold in the UK must carry a Furniture and Furnishings fire label. That is too broad. The UK Furniture and Furnishings (Fire) (Safety) Regulations 1988, as amended, primarily regulate domestic upholstered furniture and certain filling materials and covers. Loose throws, bedding blankets and travel rugs are not automatically treated the same as upholstered furniture components. Scope depends on how the product is marketed, constructed and supplied.
If the blanket is sold as a loose throw or bedding-style blanket, buyers should first confirm the applicable UK product-safety route with their compliance adviser or test lab. General product safety obligations still apply, including risk assessment, traceability and truthful labelling, but that is not the same as a mandatory permanent furniture fire label. If the blanket is supplied as part of an upholstered furniture article, used as a fitted furniture cover, or marketed in a way that brings it into furniture scope, the fire-test and labelling route may change.
BS 5852 is an ignition-resistance test method for upholstered seating composites and related materials. Ignition Source 0 is the smouldering cigarette source. Older reports may cite BS 5852:1979, while more current work is commonly reported against BS 5852:2006 or later lab methods accepted by the buyer's compliance programme. Do not accept a vague certificate saying 'BS 5852 passed'. The report should identify the exact standard version, ignition source, specimen description, fabric GSM, colour, finish, any FR treatment, test date, lab accreditation status and pass/fail observations.
Polyester flannel fleece often melts or shrinks away from a cigarette source rather than sustaining smoulder, but construction still matters. Deep raised nap, lint on the surface, heavy softener, mixed fibre contamination and printed coatings can change behaviour. If a buyer requires Source 0 for their own risk file, test the exact bulk construction and darkest/highest-risk colour, not only a light lab-dip colour.
Labelling should be separated into regimes. Fibre content, care symbols and importer/manufacturer traceability are not the same as furniture fire compliance labelling. A practical sewn-in label for UK retail can include fibre content, care instructions using ISO 3758 symbols or clear text, country of origin where required by the sales channel, importer or responsible business details, batch or PO number, and safety warnings where relevant. A fire statement should only be used when the product scope and test evidence support it.
3. MOQ, Colour Control and Price Assumptions
MOQ depends on whether the order uses available greige, existing dyed stock or a dedicated dye lot. For plain 280gsm polyester flannel fleece, small programmes may start around several hundred pieces per colour when the buyer accepts stock colours, standard sizes and standard edge finishing. Custom colour normally needs a dedicated dye lot, often in the low hundreds of kilograms of fabric per shade. Custom jacquard, special yarn, exclusive print screens or retail packaging can push MOQ higher.
For a 150x200cm blanket at 280gsm, the fabric alone weighs about 0.84kg before cutting loss, seam allowance, label and packing. A 130x170cm blanket is about 0.62kg before accessories. This simple calculation prevents false price comparisons: a supplier quoting a smaller throw can look cheaper while using the same fabric and finish.
FOB unit prices are highly date-sensitive because polyester yarn, dyeing, labour, carton board and exchange rates move. As a broad China mill reference, a plain 150x200cm 280gsm polyester flannel fleece blanket with simple hem and basic retail pack may sit in a low single-digit USD range at ordinary commercial MOQ. A more realistic RFQ should ask suppliers to break out fabric, cutting/sewing, edge finish, label/packing, inland transport, export documentation and testing charges rather than rely on a headline unit price.
The claim that 300gsm always costs 8-12% more than 280gsm is not reliable without assumptions. Fabric weight rises by about 7.1% from 280gsm to 300gsm at the same size, but the final unit increase may be lower or higher depending on wastage, edge finish, packing cube, labour and yarn price. Use a should-cost comparison: same size, same yarn, same edge, same packing, same Incoterm, same exchange-rate date.
Colour control should be written into the PO. Use a sealed master swatch, lab dip approval before bulk, and a batch tolerance such as Delta E CMC agreed by buyer and mill under D65/10 degree observer. Delta E <=1.0 is tight for fleece and may cause delay or re-dye cost; Delta E around 1.5 can be more practical for mid-price retail if visual approval is also required. For reorder programmes, keep one retained cutting from each dye lot and do not mix lots inside the same retail carton unless the buyer approves.
4. Incoterms, HS Code and Landed-Cost Controls
For UK import planning, polyester blankets and travelling rugs are generally reviewed under HS heading 6301. Synthetic fibre blankets commonly fall under the 6301.40 family in many tariff systems, but the final UK commodity code must be confirmed against the current UK Trade Tariff using fibre content, construction and intended description. Do not classify a polyester fleece blanket under a wool or fine animal hair travelling-rug line. Duty rates also change, so confirm the rate on the quotation date and again before shipment.
The commercial invoice should describe the goods plainly: '100% polyester knitted fleece blanket, 280gsm, size 150x200cm' plus quantity, net weight, gross weight, carton count and country of origin. Avoid marketing descriptions that confuse customs classification, such as 'wool-touch travel rug' when the fibre is polyester. If the blanket has a pouch, strap, gift box or coated backing, ask the forwarder whether those accessories affect declaration details.
Under Incoterms 2020 FOB Ningbo, the seller is responsible for export clearance and delivery of the goods on board the vessel nominated by the buyer. Costs before loading and local port practices must be stated in the quotation. Origin terminal handling charge, document fee, customs declaration fee, VGM, local trucking and booking charges are often treated differently by different factories and forwarders. Destination THC, UK port charges, customs clearance, duty, VAT and final delivery are normally buyer-side costs unless a different Incoterm is agreed.
Avoid the loose phrase 'FOB Ningbo includes everything to port'. Better PO wording is: 'FOB Ningbo, Incoterms 2020. Seller price to include export packing, export customs clearance, delivery to Ningbo port, origin local charges required to place goods on board vessel, and standard export documents. Buyer to pay ocean freight, insurance if required, destination charges, import clearance, duty/VAT and inland delivery.' If the seller excludes origin THC or other local charges, list the exclusion in RMB or USD before deposit.
Packing density can move landed cost more than a small sewing-cost saving. A 150x200cm 280gsm fleece blanket in an individual polybag may pack around 12-20 pieces per export carton depending on fold size and compression. Carton dimensions, carton board grade and whether vacuum compression is allowed should be fixed before freight quotation. Do not compare container load counts unless blanket size, fold, polybag thickness, carton size and maximum carton weight are identical.
5. Edge Finish, Packing and Inspection Criteria
For pop-up retail, the edge is handled constantly. A single-fold lockstitch hem is the most stable value option: specify 1.5-2.0cm hem depth, 8-10 SPI, polyester sewing thread, straight seam deviation no more than 3mm over 30cm, secure back-tack at seam ends and trimmed thread tails under 5mm. If the fabric curls after washing, the issue is usually uneven tension, poor relaxation before cutting or an over-narrow hem.
Blanket stitch gives a more visible gift feel but needs heavier thread and controlled spacing. Specify thread size, stitch density, colour standard and corner neatness. Sparse decorative stitching can snag and open after laundering. Satin binding has higher perceived value but adds two risks: ribbon shade mismatch and ribbon bleeding. For satin binding, test the ribbon separately to ISO 105-C06 and ISO 105-X12, then test the finished blanket after washing because the ribbon and fleece shrink differently.
Packing should match the sales setting. Polybag plus insert card protects against dust and customer handling but looks more promotional. Belly band exposes the hand feel and improves shelf appearance, but the blanket can pick up dirt during a wet outdoor market weekend. Gift boxes increase cube and crush risk. For cartons, specify 5-ply export carton where needed, carton gross weight usually kept below about 18-22kg for manual handling, clear shipping marks, barcode scan check and no mixed colours unless carton assortment is approved.
A useful pre-shipment inspection plan is ANSI/ASQ Z1.4 or ISO 2859-1, General Inspection Level II, with AQL 2.5 for major defects and AQL 4.0 for minor defects. Critical defects should be zero tolerance. Critical examples: needle or metal contamination, wrong fibre content, missing legally required traceability label, mould, strong chemical odour, unsafe packaging warning omission where applicable, or wrong product size by a large margin. Major examples: open seams, severe shade variation, holes, oil stains, wrong edge finish, barcode failure, carton assortment error. Minor examples: loose thread, slight fold mark, small label skew or minor carton scuff.
Needle control should be written into factory SOP, especially if blankets are sewn with labels, bindings, pouches or straps. Require broken-needle log, end-of-line metal detection where available, and documented machine-needle replacement records. For retail cartons, use a practical drop test such as ISTA 1A-style handling or buyer-specific carton drop sequence if the goods will move through parcel networks. Compression risk matters for fleece: excessive vacuum packing can reduce loft and leave hard fold lines, so approve a packed sample after at least 48 hours of recovery.

Frequently asked
Is 280gsm enough for a UK winter pop-up blanket? Yes for a soft retail throw, provided the buyer accepts a mid-weight fleece rather than a heavy sofa blanket. At 150x200cm, 280gsm gives about 0.84kg of fabric before cutting loss and packing. Warmth and shelf feel depend on brushing, pile height, edge finish and packing recovery, not GSM alone.
Should ordinary fleece blankets for UK retail carry UKCA or CE marking? Usually no. A normal non-electric loose blanket does not normally need UKCA or CE marking. Check again if the product has electric heating, toy positioning, PPE-type claims, medical claims, children's sleepwear positioning or another regulated feature.
Can we use HS code 6301.40 for all polyester fleece blankets into the UK? Do not treat it as automatic. Polyester blankets are commonly reviewed under HS heading 6301 and synthetic fibre blankets may fall in the 6301.40 family, but the importer or broker must confirm the current UK commodity code and duty rate in the UK Trade Tariff at quotation and shipment dates.
What AQL should be used for a 280gsm flannel fleece blanket order? A common retail setting is Critical 0, Major 2.5 and Minor 4.0 under ISO 2859-1 or ANSI/ASQ Z1.4. For higher-risk gift packs, children's positioning, strict barcode control or first orders with a new supplier, Major 1.5 is more conservative.
What wash test should be written into the PO? Write the ISO 6330 details, not only 'wash test'. A practical clause is 40C domestic wash, agreed reference detergent, line dry or tumble dry low according to the care label, one to three cycles depending on claim, and measurements taken before and after conditioning. State shrinkage limits such as max -3% length and -3% width.
Which edge finish is best for pop-up retail? Folded lockstitch hem is usually the safest balance of cost, durability and appearance. Overlock is cheaper but looks more promotional. Blanket stitch and satin binding improve gift presentation but add snagging, shade-match, bleeding and washing risks. Ultrasonic or heat cut edges need bulk trials because the edge can become hard, shiny or curled.
What documents should a UK buyer request before shipment? Request commercial invoice, packing list, bill of lading or sea waybill, material composition declaration, UK REACH/SVHC declaration, azo and restricted disperse dye declaration where applicable, lab reports tied to the bulk lot, barcode/carton mark approval, certificate of origin if needed, and insurance certificate if required by the Incoterm or buyer policy.
