ITWA 2026 entered its second day with booth-to-booth technical exchanges still running hot, but the conversation around translation has shifted from yesterday's "are there enough interpreters on-site?" to a stickier question — "is your translation AI-generated?" The trigger is the EU's Artificial Intelligence Act, whose transparency obligations for AI-generated content have been in force since 2 August 2026. Four months later the impact has reached Shenzhen's industrial exhibitors.
EU AI Act Article 50: AI-generated content must be identifiable
The core provision for content transparency sits in Article 50. Three practical requirements emerge: first, generative AI model providers must technically label content they generate, through machine-readable watermarks or metadata. Second, "deployers" — the companies that actually use this AI content — must clearly disclose to their audience which portions are AI-generated when they publish. Third, content on matters of public interest (news, policy commentary) must be specifically marked; commercial marketing material (product brochures) also needs marking when AI involvement is substantial.
When the Act took effect, media attention clustered on deepfake detection and social-media misinformation — few observers foresaw direct consequences for industrial translation. But transmission has been faster than expected: German industrial enterprises moved first, requiring Chinese suppliers to mark AI-generated product specifications. French automotive component manufacturers followed, making "AI-generated or AI-assisted" disclosure a formal requirement for brochures.
Which translation content needs marking?
This is the question exhibitors ask most. The Act regulates "AI-generated text", not the profession of translation itself. Three categories emerge from current enforcement practice:
Pure machine-translated output with no substantive human revision — marking required. Any file translated directly through Google Translate, DeepL or equivalent, with no substantial human rewrite. German buyers now state this requirement explicitly: files without substantive human revision must carry an "AI translated" notice.
Machine-translated first draft plus human post-editing (MTPE) — this is the grey zone. The EU Commission's June 2026 Code of Practice on Transparency mentions that "substantial modification" by the deployer can exempt content from mandatory marking, but this Code is voluntary and carries no legal force. Current German practice treats modification above 40–50% as the threshold below which marking is requested. We track MTPE modification ratios in our work and advise clients to proactively mark files below 50% revision to avoid future compliance risk.
Fully human-translated files with no AI assistance — no marking required. This includes files translated entirely from human term libraries and source material, or files where AI was used as reference but the final translation was written from scratch. Exhibitors should retain translation records proving human provenance.
Why the impact lands now on ITWA exhibitors
In the first weeks after the Act took effect, EU companies adjusted internal processes and absorbed the "deployer" role. By Q4 the transmission to supply chains began. German automotive groups inspected Tier 1 supplier documentation; French electronics manufacturers audited Chinese OEM specifications. ITWA exhibitors received these requests via email in the past week and are now confirming details face-to-face during the show — hence the sudden concentration of enquiries.
An additional accelerator: mid-October the EU Commission published guidelines on high-risk AI system translation work, explicitly classifying "professional translation files submitted for regulatory compliance" (CE, FCC, GSO) as high-risk AI output. Deployers face additional compliance responsibility if such files are primarily AI-generated.
Three compliance paths for exhibitors
Path one: full human translation. Avoids all marking issues but carries the highest cost and longest turnaround. Recommended for regulatory submission files — CE certification, import licence documentation — where pure MT should not be used in any case.
Path two: MTPE with revision ratio above 50%. Machine draft first, human revises to above 50% modification — avoids marking while remaining cost- and time-competitive. This is the path we recommend to most exhibitors. As a Shenzhen translation company, we have introduced internal modification-ratio tracking for all MTPE assignments, with a signed translator confirmation for every delivery.
Path three: proactive marking. If machine output quality is very high and revision ratio stays below 50%, mark the file "AI-assisted translation" voluntarily. This does not reduce acceptability for EU buyers, but the marking must be conspicuous and machine-readable — not buried in small grey text.
