The row of small icons on a care label decides how the customer washes the garment and who carries the blame when it comes back. The shared reference is the five-symbol system of ISO 3758: the EU requires fibre composition and care instructions side by side, while the US, Japan, Korea and Brazil each add wording of their own. This guide takes the symbols one at a time and maps where each market gets them wrong.

The temperatures and dots below follow the usual correspondences; the mandatory rules of the buyer's market always win. Brands shipping to both the EU and the US do best with a single layout that satisfies both, rather than two label versions.

1. What Each of the Five Base Symbols Controls

Symbol shape Meaning Most common error
Wash tub with a number Maximum washing temperature, with 30, 40 and 60 as the usual steps Writing cold wash, or the number without the tub
Triangle, with or without an X Whether bleaching is allowed, X meaning not allowed Words only; in the EU that reads as incomplete instructions
Square with a circle Tumble drying, with dots setting the heat level Confused with iron dots, drawn as a square with dots
Iron with dots Ironing heat: about 110°C at one dot, 150°C at two, 200°C at three Dots that do not match the stated soleplate temperature
Circle with a letter Dry-cleaning solvent class: A for any solvent, P for perchloroethylene, F for hydrocarbons Leaving the circle on a garment that must not be dry-cleaned

A symbol can carry three extras: a number for the maximum temperature, dots for intensity, and bars for a gentler cycle. Most mistakes are not wrong icons but a changed meaning once the extras are stacked on.

2. Reading Numbers, Dots and Bars

  • Wash temperature: the number is a ceiling, so 30 means 30°C or cooler; one bar is a mild cycle, two bars a very mild one.
  • Iron dots: one dot around 110°C for nylon and acrylic, two dots around 150°C for wool and blends, three dots around 200°C for cotton and linen.
  • Tumble-dry dots: one for low heat, two for normal; an X means no tumble drying, so line dry only.
  • An X means prohibited; words such as not recommended or use with care do not replace it, and inspectors treat the two differently.
  • A tub with a hand inside means professional wet cleaning, common on suits and coats, and it is not interchangeable with the dry-clean circle.

3. One Symbol Set, Different Market Rules

The EU: fibre composition and care instructions side by side under (EU) No 1007/2011, with symbols following EN ISO 3758; Germany adds the Textilkennzeichnungsgesetz (TKG), and the care label must name a reachable responsible party under GPSR (EU) 2023/988. The US mandates no symbols: 16 CFR 423 asks for washing, bleaching, drying and ironing in English words. Japan requires labelling under its household goods labelling act with the symbols of JIS L 0001 and fibre percentages; Korea requires quality labelling with KS K 0021 symbols; Brazil requires Portuguese wording under the consumer code (CDC, Lei 8.078/1990), with symbols modelled on ABNT NBR standards.

4. Symbols Only Count If They Survive the Wash

Correct symbols are not enough: a label that smears after a few washes may as well not exist. After printing or heat transfer, run the domestic wash and dry procedure of EN ISO 6330, usually three to five cycles, then check that the symbols are still legible. Keep symbols at least 5 mm high, and on dark fabric print light or reverse out. Repeated washing at 40°C exposes smeared screen-print edges first, while heat transfer holds better on synthetics.

5. The Four Most Common Mistakes

  • Words without symbols: accepted in the US, read as incomplete in the EU and Japan.
  • Wrong order: the standard sequence is wash, bleach, dry, iron, professional care, and a scrambled row gets misread in store and at the laundry.
  • One symbol carrying two meanings: putting no bleach and no dry cleaning in the same box leaves the reader guessing.
  • Mixing numbers and dots: writing 40°C as four dots hands temperature control to the iron.
Before sampling, put three things in the specification: which symbol set applies (ISO 3758 or JIS L 0001), which languages must appear, and how many wash cycles the print must pass. Once these are fixed, reprints become rare.
