How to Write a Towel Specification Sheet a Factory Can Quote Accurately

Start with the commercial use, not a reference photo

A photograph or physical sample can communicate style, but it cannot define every quotation input. Begin with a product name or SKU, intended use, destination market and expected order quantity by size and colour. State whether the towel is for retail, hospitality, spa, gym, promotional or another programme, because use conditions affect construction, testing, labelling and packing decisions.

Record the target price position if it is useful, but do not ask the factory to hit a price by silently changing the product. Mark each line as required, target or factory to propose. This gives the supplier room to offer a manufacturable alternative without obscuring where it differs from the requested product.

The core fields a towel factory needs

GSM means grams per square metre: it is mass per unit area, not a complete quality grade. ISO 3801 describes determination of mass per unit area for woven fabrics. In an RFQ, say whether the target applies to the finished, conditioned product and how it will be checked. A finished-piece weight can also be useful because borders, hems and size tolerances affect the actual unit a buyer receives. For a deeper explanation, see what towel GSM tells you—and what it does not.

Write acceptance criteria as target, tolerance and method

“Same as approved sample” is useful evidence, but it is not a complete acceptance rule. For each material characteristic, specify three things: the target, the permitted variation and the agreed method or inspection condition. For example, dimensional change should name the laundering and drying procedure, number of cycles, measurement points and allowable result—not only “low shrinkage”. ISO 5077 provides a method for determining dimensional change after a specified combination of washing and drying procedures.

Colour requirements need similar precision. Define the approved colour reference and viewing conditions, then list any colourfastness test required for the intended use. ISO 105-C06, for example, covers colour fastness to domestic and commercial laundering with stated reference conditions; it does not mean one result covers every detergent, bleach system or industrial process.

Other criteria may include finished dimensions, mass, absorbency, lint or fibre shedding, seam and hem workmanship, colour difference, logo position and appearance after laundering. Do not copy a tolerance from an unrelated product. Agree what matters for the particular towel, how it will be measured and what happens when a result falls outside the limit. The towel sample approval checklist turns these fields into a repeatable approval record.

Treat labels and packaging as specification items

Destination-market requirements should be identified before labels are ordered. In the United States, the FTC Textile Fiber Rule requires covered textiles to disclose fibre generic names and percentages by weight, the manufacturer or marketer identity, and country of processing or manufacture. In the European Union, Regulation (EU) No 1007/2011 governs textile fibre names and related fibre-composition labelling. These are examples, not a global label template: the buyer should confirm every applicable rule for the destination and sales channel.

If care symbols are requested, name the system and intended laundering context. ISO 3758:2023 provides symbols for textile care and notes that industrial laundering uses a different standard. Also attach approved label artwork, translations, materials, dimensions, fold, stitch position and packing sequence.

For packaging, specify whether pieces are rolled or folded, individually packed or grouped, how sizes and colours are assorted, units per inner and master carton, barcode or sticker requirements, and carton-mark content. Ask the factory to quote special packaging as a separate line when you are still comparing options.

Make alternative quotations visibly different

A useful quotation repeats the main specification revision and lists assumptions and exclusions. If a factory suggests a different yarn, construction, GSM, branding method or pack, ask for it as a clearly labelled alternative rather than allowing it to replace the base specification unnoticed. This preserves a like-for-like comparison between suppliers.

Give files revision numbers and dates, and keep one source of truth. When a sample changes an agreed field, update the sheet as well as the approval comments. The specification, approved physical sample, test requirements, purchase order and packaging artwork should refer to one another rather than compete.

A quotation-ready checklist

1. Name every SKU and intended use.
2. List quantities by size, colour and design—not only the total order.
3. Define finished dimensions and tolerances.
4. State target GSM and/or piece weight, plus the measurement basis.
5. Specify fibre composition, yarn and terry construction where controlled.
6. Attach colour references and artwork with dimensions and placement.
7. Define borders, hems, labels, care information and packaging.
8. Name required tests, methods, conditioning or wash conditions, and acceptance limits.
9. Identify the destination market and buyer-supplied compliance requirements.
10. Mark open decisions and request separately priced alternatives.

Before sending the RFQ, ask someone who has not worked on the product to read it. If they cannot tell what is mandatory, what is optional and what must be proposed, the factory will probably have the same question.

Briefing a towel manufacturer in Vietnam

For a factory-direct discussion with Son Ha Textile in Phùng Xá, Hanoi, send the specification sheet with reference samples or images, artwork and a quantity breakdown. The team can then review the requested construction, sampling needs, packing and export context before commercial details are confirmed. You can also review Son Ha’s manufacturing capabilities, partnership approach and the broader guide to sourcing towels from Vietnam.

Frequently asked questions

Do I need both GSM and finished piece weight?

Not always, but recording both can reduce ambiguity. GSM describes mass per unit area; piece weight describes the finished unit, including the effect of actual dimensions, borders and hems. State which is the controlling requirement if the values do not align exactly.

Can a factory quote from an existing towel sample?

A reference sample is helpful for feel and construction, but the factory still needs quantities, fibre declaration, dimensions, colour, branding, labels, packaging, destination and acceptance criteria. If the sample cannot be destructively analysed, identify which characteristics are estimates.

Should I specify a universal towel tolerance?

No. Tolerances should reflect the product, process, test method and business need. Discuss achievable limits with the manufacturer, record them before approval and avoid applying a figure from another towel without checking its relevance.

What should remain open for the factory to propose?

Leave room where manufacturing input creates value: yarn count, detailed construction, finishing route, pack optimisation or an alternative branding method may be proposal fields. Keep end-use, appearance, performance, compliance and commercial constraints explicit so the proposal still answers the same brief.
