A Costly Translation Error

Translation is often seen as a mere detail — a formality to be handled at the end of a process. Yet in many cases, a simple translation error can lead to catastrophic consequences — reputational, legal, or financial. And some companies have paid the price… by the millions.

Here are three real-world examples of costly translation errors, and what they teach us about the importance of professional, high-quality language services.

✔️ 1. HSBC and its famous “Do Nothing”

In the early 2000s, HSBC launched an international campaign using the slogan “Assume nothing,” meant to reflect their personalized approach to client services. The problem? In many countries, the slogan was poorly translated — sometimes as “Do nothing.”

Result: this translation error completely reversed the original message, ruining a major marketing investment.

➡️ Cost of the mistake: $10 million USD to relaunch a brand repositioning campaign.

Lesson learned: A slogan or marketing message cannot be translated literally. It must be localized, culturally adapted and tested in each target market.

✔️ 2. The mistranslation of a medication label in Canada

In 2011, Health Canada faced a serious situation: the French-language label for a drug prescribed to pregnant women had been mistranslated. An awkward phrase caused misinterpretation of the dosage. This translation error led to confusion about the correct dosage, with serious medical consequences.

Patients received incorrect quantities of the drug, resulting in multiple complications.

➡️ Cost of the mistake: Class-action lawsuits, temporary product withdrawal and damage to the manufacturer’s credibility.

Lesson learned: In sensitive fields like healthcare, a translation error isn’t just expensive — it can also put lives at risk. That’s why regulated industries require expert translators.

✔️ 3. The failed airline agreement

An Asian airline was negotiating a partnership with a European company. In an email exchange in English, the phrase “we are considering your terms” was internally mistranslated as “we accept your terms.” The European partner then made costly logistical decisions, believing the deal was finalized.

The airline later declined the offer, leading to a legal dispute.

➡️ Cost of the mistake: Several hundred thousand euros in losses and legal fees.

Lesson learned: In business communication, every word matters. A translation error in a key message led to a contract misunderstanding with expensive consequences.

✅ What these mistakes have in common

These very different examples share a key element: the strategic importance of translation is often underestimated — along with the risks a translation error can pose. Whether in marketing, business, healthcare or law, translation isn’t just about switching words between languages.

It’s all about interpreting, adapting, checking, validating. It requires:

• Full mastery of both languages;
• Deep understanding of the context;
• Subject-matter expertise (medical, legal, technical, etc.);
• A rigorous review process.

✅ How to avoid these mistakes?

Here are some best practices to avoid making translation your Achilles’ heel:

1. Work with qualified professionals, ideally specialized in your field.
2. Validate key messages (slogans, headlines, legal disclaimers) with local linguists.
3. Involve translation early in the process, not at the very end.
4. Plan for revision by a second translator, especially for sensitive documents.

At Traduction-Québec, we believe translation is a responsibility — not just a box to check. Every word matters, every nuance counts. And it’s precisely this level of care that protects you… from the consequences of a translation error.
