Surface Treatment (Oberflaechentechnik)

GewO §94 Z.51   Verified: April 2026

Key Facts

  • Type: Regulated trade (Handwerk)
  • Qualification: Master exam (Meisterpruefung)
  • Registration cost: Free (€0)
  • Environmental: Strict chemical and wastewater regulations
  • Note: a business premises approval is regularly required here — surface treatment usually meets the hazard test of § 74 (2) GewO, but the duty follows that test, not the trade

What This Trade Covers

Environmental Compliance Surface treatment operations use hazardous chemicals (acids, heavy metals, solvents). A business premises approval (Betriebsanlagengenehmigung) will regularly be required, because whether a permit is needed depends on the hazard test in § 74 (2) GewO and this trade normally meets it. Wastewater treatment, emission controls, and hazardous waste disposal must meet strict Austrian and EU environmental standards.

One qualification, several trades

Austrian trade law lists this as a verbundenes Handwerk (combined trade). § 94 Z 51 GewO reads, verbatim: „Oberflächentechnik; Metalldesign (verbundenes Handwerk)“

This is worth more than it looks. Under § 30 (1) GewO, once you have the qualification for one of the trades named there in full, you may also provide the services of the others — no second exam. The same applies under § 30 (2) if the authority has recognised your individual qualification (§ 19) without restricting it to partial activities.

What this licence additionally covers

§ 150 GewO grants rights beyond the trade's own field — no second registration needed. The statute is quoted below verbatim in German; we do not paraphrase legal text.

§ 150 (16): „Metalldesigner (§ 94 Z 51) sind auch zur Ausübung der Tätigkeiten des Gewerbes der Gold- und Silberschmiede (§ 94 Z 29) und der Gold-, Silber- und Metallschläger (§ 94 Z 29) berechtigt.“

Qualification: how to prove it

Oberflächentechnik is a regulated trade under §94 Z.51 of the Austrian Trade Act (GewO 1994). The standard route is the qualification exam (befähigungsprüfung).

  • Examined by: WK
  • Exam modules: 5
  • Exam fee: €0 — exam fees are covered by the federal government

If you cannot sit the exam, these routes are open to you:

  • Individual assessment under §19 GewO
  • Appointing a qualified managing director

Registering the trade

  • Cost: Free — registration itself carries no fee
  • Where: District administrative authority (Bezirksverwaltungsbehörde)
  • Decision within: max. 3 months
  • Typically takes: 1-5 Werktage (bei vollständigen Unterlagen)
  • Start trading: immediately on registration — you do not have to wait for the decision

You can register in these ways:

  • Online via GISA (the trade register)
  • Online via USP (the business service portal)
  • In person at the authority

Sole trader, GmbH, or partnership?

Trade law does not prescribe a legal form — but it does draw one line. Under § 9 (1) GewO, legal entities and registered partnerships (GmbH, OG, KG) may hold a trade licence, but they „must have appointed a managing director (§ 39)“ — a named person who carries the qualification and the legal responsibility for the trade. As a sole trader you are that person yourself.

Whether a GmbH pays off financially depends on profit, drawings, SVS contributions and allowances. There is no general profit threshold, and that question belongs to a tax adviser, not to this page.

Running this trade alongside a job

Nothing in Austrian law forbids running a trade as a side business. Two things about social insurance are regularly misremembered, and both cost money.

  • The obligation follows Chamber membership, not profit. Under § 2 (1) 1 GSVG compulsory SVS insurance attaches to membership of the Economic Chamber, which you acquire with the trade licence itself. It therefore applies in a year in which you make no profit at all.
  • There is an exemption — but only on application. § 4 (1) 7 GSVG lets very small businesses be exempted while turnover and income stay under the limits it refers to. Nothing happens automatically: without the application, the obligation stands.

If you are employed, check your employment contract separately for a secondary-activity clause — that is a matter between you and your employer, not trade law.
