How to Translate an E-Commerce Product Catalogue for International Markets

Key Takeaways

• Translating an e-commerce product catalogue for international markets requires far more than converting product titles and descriptions word for word. Measurements, sizing systems, currency formats, and cultural references all need adapting for each target market.
• Product content that reads naturally in English often produces awkward, unconvincing copy when translated without localisation. Shoppers are more likely to convert when product descriptions feel written for them rather than translated at them.
• Large product catalogues containing thousands of SKUs require Translation Memory (TM) software to maintain consistent terminology, reduce per-word costs on repeated content, and accelerate delivery timelines.
• Marketplace platforms including Amazon, Zalando, and ASOS Marketplace each have their own formatting requirements. Translated listings must conform to platform-specific character limits, bullet structures, and backend search term fields.
• ISO 17100:2015 certified translation workflows guarantee that product content is reviewed by a second native linguist before going live, preventing terminology errors that damage brand credibility.

For UK brands expanding into European, Asian, or North American markets, the product catalogue is the commercial engine of the entire business. Every product title, description, bullet point, and specification page contributes to search visibility, conversion rates, and brand credibility in that market.

Translating a product catalogue is one of the highest-volume, highest-stakes translation projects a retail business can undertake. Done well, it unlocks new revenue streams and builds international brand trust. Done poorly, it produces confusing, unconvincing copy that pushes shoppers toward local competitors.

This guide walks through everything UK e-commerce brands need to know before translating a product catalogue for international markets.

Step 1: Audit Your Source Catalogue Before Translation Begins

Translating poor source content simply produces poor translated content in multiple languages. Before briefing a translation project, review your existing product catalogue for:

• Inconsistent product naming: If the same product is described differently across SKU variants, translators will reproduce those inconsistencies in every target language.
• Outdated specifications: Check that dimensions, materials, and care instructions reflect the current product rather than an earlier iteration.
• Colloquialisms and idioms: Phrases like "does exactly what it says on the tin" or "bang for your buck" have no direct equivalent in German or Japanese and require creative adaptation rather than literal translation.
• Placeholder copy: Generic filler text ("high quality product", "great value") adds no SEO or conversion value in any language. Remove it before translation.

A clean source catalogue produces cleaner, more cost-effective translations across every target language.

Step 2: Define Your Target Markets and Localisation Requirements

Not every market requires the same depth of localisation. The requirements differ significantly across regions:

EU Markets (Germany, France, Spain, Italy, Netherlands)

• Sizing must be converted from UK to EU standards (clothing, footwear, bedding).
• Prices display with local currency and VAT-inclusive formatting.
• Legal disclaimers and warranty language must reflect EU consumer rights legislation.
• Product descriptions should use formal register (Sie in German, vous in French) for most retail categories.

Middle East (UAE, Saudi Arabia, Kuwait)

• Right-to-left (RTL) text layout for Arabic requires DTP adjustment of product image placement and text alignment.
• Halal certification references must be handled carefully and accurately for food and cosmetic products.
• Seasonal references need updating as peak retail periods differ from the UK calendar.

East Asia (Japan, South Korea, China)

• Japanese product descriptions benefit from shorter, more precise sentence structures rather than long descriptive paragraphs.
• In China, product claims regarding health benefits, certifications, and materials are subject to strict advertising regulations.
• Korean e-commerce shoppers respond strongly to detailed product specifications, origin information, and material composition details.

Step 3: Use Translation Memory to Manage Scale

A mid-size e-commerce catalogue can contain anywhere from 500 to 50,000 product descriptions. Translating every line from scratch on each update is costly and slow.

Translation Memory (TM) software like MemoQ solves this:

• The first time a product description or specification phrase is translated, it is stored in a project-specific TM database.
• On subsequent catalogue updates, identical or near-identical segments are automatically matched and pre-populated, requiring only light review rather than full re-translation.
• Across a catalogue with significant repeated phrasing (care instructions, material descriptions, warranty terms), TM matches typically reduce translation volumes by 30% to 50%, cutting both cost and turnaround time considerably.
• All product names, registered trademarks, and brand terminology are locked in a client glossary to prevent inconsistencies across translators.

Step 4: Adapt for Marketplace Platform Requirements

If your products are listed on third-party marketplaces, translated content must conform to each platform's specific formatting rules:

Amazon International Marketplaces

Amazon product listings have strict character limits for titles (typically 200 characters), bullet points (five bullets, each under 500 characters), and product descriptions. Translated German product titles, for example, expand significantly in length due to compound noun structures and must be edited to fit within character limits without losing key search terms.

Zalando

Zalando requires product descriptions in a specific descriptive tone and forbids certain promotional language. Translated descriptions must pass Zalando's content validation checks before going live.

Shopify International

Shopify's Markets and Translate & Adapt features allow multi-language storefronts but require properly segmented translation files. We work directly within Shopify's translation export formats to deliver catalogue translations that import cleanly without breaking product variant structures.

Step 5: Apply ISO 17100 Quality Review Before Publishing

Before any translated product content goes live, it must be reviewed by a second native linguist who checks:

• Consistency of product terminology against your approved brand glossary.
• Natural, idiomatic phrasing that reads as written for local shoppers rather than translated.
• Numerical accuracy across dimensions, weights, capacities, and pricing.
• Compliance with platform character limits and formatting requirements.

Skipping this step and publishing first-pass machine-translated or unreviewed catalogue content is one of the most common and costly mistakes UK brands make when entering international markets.
