Clothing Rules by Market: US, EU, and UK Compared

A clothing brand that sells in the United States, the European Union, and the United Kingdom must navigate three separate regulatory frameworks for what is fundamentally the same product. The US requires a flammability certificate and FTC labeling. The EU requires REACH SVHC communication and GPSR compliance. The UK — since Brexit — requires its own UKCA marking and separate chemical compliance documentation. None of these frameworks accept the others' certificates.

This guide compares apparel compliance across all three markets and explains how to manage it without tripling your regulatory overhead.

US Clothing Brand: The Rules Most Founders Miss

Starting a clothing brand looks simple: design some pieces, find a manufacturer, launch a website. What catches most first-time apparel founders off guard is the compliance — not the design. Your fabric choice affects which flammability standard applies. Your trim supplier determines whether you need a Prop 65 warning. Your packaging can make your product illegal in California if it fails a heavy metal test.

This guide walks through launching a clothing brand with the compliance steps built in at each stage — so you are not reworking labels and repackaging inventory the week before launch.

On the Sustalium platform, the apparel compliance issue we see most often is not missing flammability tests — it is missing Prop 65 assessments. A brand launches a clothing line with a valid GCC, correct FTC labels, and compliant packaging. Six months later, a Prop 65 enforcement notice arrives because a metal zipper or a screen-printed design contained a listed chemical above the safe harbor level. The testing costs $300. The settlement costs 100 times that.

US Apparel Compliance: Flammability, Labeling & Rules

Apparel compliance in the United States is deceptively fragmented. The federal requirements are relatively minimal — a flammability standard, a fiber content label, and a country of origin marking. But state-level obligations — California's Proposition 65, the emerging NY Fashion Act, PFAS restrictions across multiple states, and packaging heavy metal rules — add layers of compliance that many apparel importers discover only at the point of enforcement.

This guide maps every US compliance requirement for apparel and textiles, from the federal baseline through the state-level obligations that increasingly define market access.
