Guest Supply Specification Sheet Fields

Why one missing line can change your quote by more than the logo

Most quotation drift starts before yarn is booked. A buyer asks for a 30×30 cm face towel and assumes every mill reads that as the same article. We do not. One mill may quote 380 GSM ring-spun with a 10s single ground yarn, another may quote 420 GSM combed cotton with a tighter reed setting, and a third may quote weight after finishing while you expected loom-state weight. All three can say "matches spec" if the guest supply specification sheet is thin.

For hospitality programs, the cost movement is usually hidden in construction details rather than decoration. On a recent tender for a 50×90 cm hand towel, changing from 16s/1 carded pile to 16s/1 combed pile added about USD 0.11 per piece at 8,000 pcs. Tightening shade tolerance from mill standard to approved lab dip against Pantone under D65 lightbox added another USD 0.02-0.03 because of extra dye control and rework risk. Neither line was clear in the buyer's first document.

Spec line omitted	Typical result in quoting	Commercial effect
Weight basis	Suppliers quote different GSM assumptions	FOB spread can widen by USD 0.08-0.19/pc
Shrinkage tolerance	Finishing route changes	Higher reject risk after wash approval
Carton packout	Packing costs vary by count and insert requirements	Freight cube and labor both shift
Colorfastness standard	Some quote internal standard only	Bulk may pass mill QC but fail hotel laundry trial

The eight fields every buyer should lock first

If your team needs a working document quickly, do not start with 40 fields. Start with the lines that decide whether two supplier quotes are actually comparable. For a usable guest supply specification sheet, these eight should be fixed before you ask for price:

1. Product name and end use: washcloth, hand towel, bath towel, bath mat, spa towel, pool towel
2. Finished size in centimeters, with tolerance after wash
3. Target GSM and whether tolerance is plus/minus or minimum only
4. Fiber content and yarn type: 100% cotton, combed cotton, zero-twist blend, cotton/poly
5. Construction notes: dobby border width, cam border, headerless, pile style, loop density
6. Color reference and matching condition: Pantone TPX/TCX, physical swatch, existing towel
7. Required tests and pass levels
8. Packing method: inner bag, carton count, barcode, carton dimensions or weight limit

These are not abstract admin fields. Border width affects loom setup and logo position. A request for "soft hand feel" without stating whether silicone softener is allowed creates trouble later if your property laundry program restricts finish buildup. A request for "white" without whiteness expectation can produce very different outcomes depending on optical brightener use and peroxide bleaching sequence.

How we format size, weight, and tolerance so QC can actually inspect it

A specification is only useful if the bulk inspector can check it with the same logic used by the buying team. We suggest writing dimensional lines in a measurable format, for example: "Finished size 70×140 cm, tolerance -3% / +2% after one home-laundering cycle at 40°C." That line tells sampling, finishing, and final inspection what standard to work to.

For weight, the cleanest approach is to state both target and acceptance band. Example: "Nominal 520 GSM, shipment acceptance 505-535 GSM on conditioned finished goods." If you only write "520 GSM," mills may interpret that as target average rather than shipment floor. We condition test swatches before weighing because moisture regain can distort readings, especially during humid months.

• Use centimeters, not mixed cm/inch formats
• State whether size is measured before or after washing
• State whether GSM is conditioned finished weight
• Add tolerance as a number, not words like "industry standard"

Field	Weak wording	Usable wording
Size	Bath towel 70×140	Finished 70×140 cm, measured after 1 wash, tolerance -3% / +2%
Weight	Around 500 GSM	Target 500 GSM, acceptance band 490-520 GSM on conditioned finished goods
Border	Standard border	Dobby border 4.0 cm top and bottom, no side border
Color	Bright white	Reactive white program with buyer-approved standard; no visible shade variation within lot under D65

Construction lines that look minor on paper but matter in bulk

This is the part many hotel procurement files skip because the towel "looks simple." It is not. Two towels with the same size and GSM can behave very differently in laundry if the construction line is vague. We have seen edge grin appear after twenty wash cycles because the side seam allowance was too narrow for the pile density. We have also seen border puckering on embroidered hand towels because the border was woven too light for the stitch count planned later.

At minimum, specify pile type and border structure. For example, a pool towel with high visual loft may use a looser pile and lower loop bind than a room bath towel intended for commercial wash endurance. A bath mat may need lower pile height and stronger warp support to keep shape after tumbler drying. If your guest supply specification sheet covers several towel categories, each needs its own construction note rather than one copied standard.

• Pile yarn: carded, combed, low-twist, zero-twist blend
• Ground yarn count and ply where relevant
• Border type: cam, dobby, jacquard border, hemmed all around
• Hem depth and side seam allowance
• Special finish limits: no cationic softener, low-lint target, bleach-safe color route

One practical example: a 600 GSM retail-style bath towel can impress in sampling, but for a city hotel with continuous tunnel-wash processing, a 500-540 GSM construction with stronger selvedge retention often gives lower replacement spend over twelve months. That is not a universal rule; it depends on laundry chemistry, extraction force, and room category. The point is that the sheet should reflect end use, not just showroom feel.

Tests to write into the document, with methods your suppliers will recognize

A good hotel towel technical data sheet does not say only "must pass colorfastness." It names the method or at least the test family. For cotton terry, we usually see buyers ask for wash colorfastness, rubbing fastness, absorbency, dimensional stability, and restricted substances compliance. If your operating region uses outside laundries, add a simple wash trial against your actual detergent and drying conditions before bulk approval.

Performance item	Common method	Typical commercial expectation
Colorfastness to washing	ISO 105-C06	Grade 4 minimum on color change for standard shades
Colorfastness to rubbing	ISO 105-X12	Dry 4 minimum; wet 3-4 minimum depending on shade depth
Dimensional change after washing	ISO 5077 or buyer laundry trial	Usually within 3-5% depending on item
Absorbency	Internal drop test or buyer method	Rapid wet-out with no obvious finish barrier

For chemical compliance, OEKO-TEX Standard 100 Class I is the cleanest common benchmark for many export buyers, even when the end use is not infant. If you ask for OEKO-TEX, make the certificate line item-specific during approval rather than assuming a generic factory certificate covers all dyed lots. For social and quality systems, BSCI and ISO 9001 are still standard screening lines, but they do not replace product testing.

A detail that saves arguments later: if dark shades are involved, state whether wet crocking grade 3 is acceptable or whether you require 3-4 or better. Navy, charcoal, and black terry often need tighter process control and may still not perform like white or pale beige under aggressive hotel wash chemistry.

Packout is part of the product, not an afterthought

Freight claims and receiving delays often come from the packaging lines that buyers leave blank. If you need shelf-ready amenity packs for a boutique group, that must sit in the same document as the towel specs. If you need simple export cartons for central warehouse receiving, write the carton count, gross weight cap, shipping marks, barcode type, and whether mix-size cartons are prohibited.

One resort client changed only one line in its packout: from 100 pcs per carton to 60 pcs per carton for a 100×180 cm pool towel. Piece cost rose by about USD 0.04 because corrugated use and packing labor increased, but they avoided repeated carton burst during local handling and reduced stain claims from floor contact in back-of-house. That was a sound trade.

• Carton count per SKU
• Maximum carton gross weight, often kept below 18-22 kg depending on region
• Inner polybag requirement or no-poly instruction
• Carton marks: PO, item code, color, country of origin, barcode format
• Palletization requirement if shipping to a DC

Price bands by item type when the sheet is complete

Below are practical FOB China bands for standard export orders when the specification is complete enough for clean quoting. These are not spot-market promises. They assume OEKO-TEX-compliant raw materials, MOQ 500 pcs per design per color, and standard woven terry without complex retail gift packaging. Cotton market moves, dye class, and border detail can shift the numbers.

Item example	Spec snapshot	Volume	Indicative FOB China
Washcloth	30×30 cm, 420-460 GSM, 100% cotton, white	10,000 pcs	USD 0.33-0.46/pc
Hand towel	50×90 cm, 450-520 GSM, reactive dyed	8,000 pcs	USD 1.04-1.42/pc
Bath towel	70×140 cm, 500-560 GSM, combed cotton	5,000 pcs	USD 3.28-4.18/pc
Bath mat	50×80 cm, 700-850 GSM, reinforced hems	5,000 pcs	USD 1.42-2.05/pc

The reason a complete guest supply specification sheet helps here is simple: the tighter the document, the narrower the quote spread for comparable goods. If you issue a vague RFQ, you may receive five offers that differ by more than 20%, yet only two are actually built to the durability level your operation expects.

Lead times from RFQ to bulk approval

Buyers often compress calendar time by focusing on production days only. In practice, the slowest part is usually approval traffic: confirming the spec form, lab dips, handloom or machine sample, and packaging artwork. For recurring white hotel programs the cycle is shorter. For dyed sets or programs with embroidery, barcode labels, or mixed property requirements, plan more review time.

Stage	Typical timing	What should be signed off
RFQ review and clarifications	2-4 days	Final data fields on the specification sheet
Lab dip / shade approval	4-7 days	Color standard and allowed variation
Sampling	7-12 days	Construction, hand feel, size, logo if any
Bulk production	18-32 days	Approved pre-production sample and packout
Final inspection and dispatch	3-5 days	AQL result, carton marks, shipment release

If your delivery window is narrow, do not wait until the PO stage to define carton labels or barcode symbology. We have seen EAN label changes hold shipments for two days because old artwork was already printed and applied to export cartons.

How buyers should use the sheet during supplier comparison

Treat the document as a bid-control tool, not just a product note. Send the same version to every supplier. Require them to fill in any blank technical field rather than leaving assumptions unspoken. Ask them to state where they are deviating. That makes supplier comparison much cleaner and exposes which quote is low because of an actual efficiency advantage and which is low because the article being priced is lighter, looser, or packed differently.

1. Issue one controlled version with revision date
2. Mark buyer-fixed fields versus supplier-fill fields
3. Request explicit confirmation of test methods and tolerances
4. Require sample comments against the same document
5. Lock the approved version before deposit and bulk booking

For teams building new hospitality programs, it helps to pair the sheet with a launch calendar and a supplier-ready tech pack. Related reads: build a towel tech pack that mills can quote, hotel towel sourcing guide 2026, and setting up hotel linen program 90 day roadmap.

A workable template for your internal approval meeting

Before your purchasing team sends an RFQ, run a 15-minute cross-check with operations or housekeeping. The goal is not to make the form longer. It is to remove the lines that create avoidable ambiguity. If a property expects heavy chlorine exposure, say so. If towels are for guest room display and low laundry rotation, that also changes what matters.

• Commercial: target volume by SKU, destination, Incoterm, requested ship window
• Product: size, GSM, color, construction, logo, hand feel limits
• Compliance: OEKO-TEX 100 Class I if required, BSCI/ISO 9001 supplier screening
• QC: wash, rubbing, shrinkage, absorbency, AQL level, sample retention
• Packing: carton count, barcode, assortment rules, pallet or floor-load requirement
