What ISO 3758 covers
ISO 3758 establishes graphic symbols for care labelling of textile articles. The symbols cover domestic washing, bleaching, drying and ironing, plus professional dry cleaning and wet cleaning. The standard is intended to communicate care information to the end user in a compact, consistent way.
The standard does not cover every object made with fabric. ISO's own abstract excludes certain non-removable furniture covers, non-removable mattress covers, and carpets or rugs that require professional carpet cleaning. For those products, use the relevant product-specific route rather than forcing a clothing-style label onto them.
- Published edition: ISO 3758:2023.
- Core treatments: wash, bleach, dry, iron, professional clean.
- Purpose: show severe treatments that should not irreversibly damage the textile.
Symbols describe limits, not preferences
A care symbol should describe the harshest treatment the article can safely tolerate, not the nicest way to pamper it. If a garment can be machine washed at 40 C without damage, the label should not imply dry clean only just because it sounds premium. Misleading over-restriction can frustrate customers and may create compliance issues in some markets.
At the same time, do not overpromise. If a hand-dyed cotton dress fades in warm water, do not mark it as a normal 40 C wash because the base fabric can handle it. The finished article includes dye, thread, trims, elastic, interfacing, print and construction.
Use the correct symbol order
Care labels commonly present symbols in the treatment sequence: washing, bleaching, drying, ironing and professional cleaning. This order helps customers and cleaners read the label quickly. It also keeps your labels consistent across styles.
If you add text, keep it short and directly tied to the symbols. Examples include wash with like colours, reshape while damp, dry flat, remove belt before washing, or turn inside out. Extra care text should clarify real risks, not fill space.
Test the finished article
ISO symbols are only as accurate as the care decision behind them. Test the finished item or a representative sample using the care process you plan to label. Measure shrinkage, colour change, seam twisting, trim damage, pilling, print cracking and texture change after washing and drying.
A fabric supplier's care recommendation is a starting point, not a finished product label. Your sewing thread, lining, buttons, embroidery, fusible interfacing and hand-dye process can lower the safe care level.
- Test after sewing, printing or dyeing where possible.
- Check shrinkage before and after drying.
- Use the weakest component to set the care limit.
Market rules still matter
ISO 3758 is a standard, not the whole law for every country. The United States has FTC care label rules and recognises ASTM care symbols for rule compliance. Other markets may use ISO-based or GINETEX-based systems and may have language, licensing or placement expectations.
If you sell internationally, decide your target markets before printing labels. One symbol set may be familiar to customers in one region but not accepted as a complete care instruction in another. Use local compliance guidance when needed.
Avoid symbol artwork problems
Do not redraw care symbols casually, distort them to fit a brand style, or use random icon sets from the internet. Symbol shape, bars, dots and crosses carry meaning. Small changes can change or confuse the instruction.
Keep symbols high contrast, large enough to read and durable for the life of the garment. A care label that fades after three washes is not doing its job. If you use printed satin, cotton labels or heat transfers, test legibility after care cycles.
Frequently asked questions
What is the current ISO care label standard?
ISO lists ISO 3758:2023 as the published edition for textile care labelling code using symbols.
Does ISO 3758 apply to all textile products?
No. ISO's abstract excludes some non-removable upholstery and mattress covers and carpets or rugs requiring professional carpet cleaning.
Can ISO symbols replace US care words?
Not automatically. The US FTC rule specifically discusses ASTM care symbols. Check the target market before using ISO symbols alone.
Do care symbols need to be in a specific order?
They are commonly shown in the sequence washing, bleaching, drying, ironing and professional cleaning.
Can I change the icons to match my branding?
No. Do not stylize symbols in ways that alter or obscure their meaning. Use correct, legible care symbol artwork for the market.
