Simplified Chinese Translation Services
International Translating Company (ITC) provides professional Simplified Chinese translation services powered by native linguists from mainland China and more than 55 years of continuous operation since 1969. From tech manufacturing and pharmaceutical regulatory filings to F-1 student visa documents and cross-border e-commerce content, our team delivers accurate, culturally fluent translation across 230+ languages with deep expertise in both English-to-Chinese and Chinese-to-English directions.
Simplified Chinese Translation for Key Industries
Tech Manufacturing and Electronics
China is the world’s largest electronics and component exporter, and US-China trade generates continuous demand for technical translation. Semiconductor manufacturers, EV companies (BYD, NIO, Xiaomi), and consumer electronics brands (Lenovo, Huawei) all require precise EN-to-ZH and ZH-to-EN translation for technical specifications, supplier contracts, regulatory submissions, and software localisation. ITC’s linguists understand the engineering vocabulary, tolerance specifications, and compliance terminology that manufacturing documentation demands.
Pharmaceutical and Life Sciences (NMPA)
China’s National Medical Products Administration (NMPA) filings, the biotech sector, and companies like BeiGene and WuXi AppTec drive sustained demand for regulatory translation between English and Simplified Chinese. ITC handles clinical trial documents, Investigational New Drug (IND) applications, package inserts, and manufacturing documentation with linguists who understand GMP, GLP, and ICH terminology. Our pharma translation process includes a second-linguist review for regulatory submissions to catch any terminology that could trigger a regulator query.
Legal and Intellectual Property
US-China IP litigation, patent filings, cross-border mergers and acquisitions, and regulatory enforcement actions all require precise legal translation. Contract translation under PRC contract law conventions must align with US-law legal review on the parallel track. ITC’s legal translation linguists handle patent specifications, litigation discovery, corporate filings, and enforcement documentation with strict attention to the legal terminology differences between US and PRC jurisdictions.
Cross-Border E-Commerce
The explosion of cross-border e-commerce, from Amazon seller flows to Temu, Shein, and TikTok Shop, has created massive demand for product listing translation, marketing copy, user agreements, and consumer-dispute documentation. ITC translates product descriptions, A+ content, brand registry materials, and customer service templates for e-commerce sellers operating between the US and China. Our linguists adapt marketing copy to read naturally for mainland Chinese consumers, not as direct translations of English copy.
F-1 Student Visa and H-1B Immigration
The sustained flow of Chinese students to US universities, especially in STEM graduate programmes, generates consistent demand for certified translation of diplomas, transcripts, and identity documents for USCIS and university admissions. ITC provides certified Chinese translation of academic credentials with course-level detail, institutional naming conventions, and grading-system explanations that admissions offices and credential evaluators expect. We also handle H-1B and employment-based immigration document translation.
Manufacturing Supply Chain Documentation
The dominant US-China translation flow at scale is supplier documentation: supplier qualification forms, factory audit reports, ESG and labour-compliance documentation, supplier quality manuals, and logistics records. ITC translates these documents with consistency across long-running supplier programmes, maintaining a terminology glossary for each client to ensure that the same component, process, or standard is translated identically across every document in the supply chain.
Chinese Language Expertise
Simplified vs Traditional Chinese
Simplified Chinese (简体中文) is the script of mainland China, while Traditional Chinese is used in Taiwan, Hong Kong, and Macau. A “Chinese” deliverable without script confirmation is potentially unusable: simplified reads as foreign typography to a Traditional-Chinese reader and vice versa. The simplification reform of the 1950s and 1960s reduced component complexity by roughly 70% for thousands of characters. ITC confirms script at intake before assignment, every time.
Mainland China vs Taiwan Terminology
Even at conversational level, mainland-trained and Taiwan-trained translators diverge in medical, legal, and technical vocabulary. The same English term may have completely different accepted translations in PRC mainland versus Taiwan contexts. Cantonese Chinese and Mandarin Chinese add further regional variation. ITC confirms the target jurisdiction (PRC mainland, Taiwan, Hong Kong, Macau) before assignment and routes to a linguist from the correct region.
Direction: English to Chinese and Chinese to English
EN-to-ZH is the dominant flow for US businesses translating marketing, training, and software materials into Chinese. ZH-to-EN is lower in volume but high in stakes: NMPA regulatory submissions, scientific publications, IP litigation documents, and supplier documentation that originate in Chinese and must be translated into English for US regulatory or legal use. ITC handles both directions with native source-side linguists, meaning a Chinese-to-English project is assigned to a linguist whose native language is English, and vice versa.
Certified Chinese Translation
ITC provides certified translation services for all Simplified Chinese documents required by US courts, USCIS, academic institutions, and government agencies. Our certified translations include a signed certificate of accuracy, translator credentials, and notarisation when required. We handle diplomas, transcripts, birth certificates, marriage certificates, household registrations (户口本), police certificates, and employment verification letters with full attention to the institutional vocabulary of PRC official documents.
Our Translation Process
1. Intake and specification. We confirm source and target languages, script (Simplified or Traditional), target jurisdiction (PRC mainland, Taiwan, HK, Macau), subject matter, file format, and deadline.
2. Linguist assignment. We match the project to a native linguist from the correct region with relevant industry experience (tech, pharma, legal, e-commerce, immigration, or supply chain).
3. Translation and self-check. The linguist translates and reviews against source for completeness, terminology, and character accuracy.
4. Independent review. A second qualified linguist reviews for terminology, register, and jurisdictional appropriateness.
5. Formatting and delivery. We deliver in the requested format, with certified documentation if required.

Frequently Asked Questions
What is the difference between Simplified and Traditional Chinese?
Simplified Chinese (简体中文) is used in mainland China. Traditional Chinese (繁體中文) is used in Taiwan, Hong Kong, and Macau. The scripts differ in character forms, and using the wrong one makes the deliverable unreadable or inappropriate for the target audience. ITC confirms the script at intake.
Can you translate Chinese documents for USCIS?
Yes. ITC provides certified Simplified Chinese to English translation for USCIS filings, including birth certificates, marriage certificates, household registrations (户口本), police certificates, and academic transcripts. Our certified translations include a certificate of accuracy.
Do you handle both English-to-Chinese and Chinese-to-English translation?
Yes. English-to-Chinese is the dominant flow for US businesses localising materials for the Chinese market. Chinese-to-English is common for regulatory submissions, IP litigation, and supplier documentation. ITC assigns native target-side linguists for each direction.
How do you handle mainland China versus Taiwan terminology differences?
Mainland-trained and Taiwan-trained translators use different vocabulary for medical, legal, and technical terms. ITC confirms the target jurisdiction at intake and assigns a linguist from the correct region to ensure the deliverable reads naturally for the intended audience.
Can you translate NMPA regulatory filings?
Yes. Our pharmaceutical translation team handles NMPA submissions, IND applications, clinical trial documents, package inserts, and manufacturing documentation with linguists who understand GMP, GLP, and ICH terminology.
What file formats do you support for Chinese translation?
We support all standard formats including Word, Excel, PowerPoint, PDF, InDesign, XML, JSON, and various localisation file types. For software and website localisation, we work with your CMS or localisation platform directly.
How quickly can you deliver Simplified Chinese translation?
Standard documents (birth certificates, one-page letters) are typically delivered within 24 to 48 hours. Larger projects receive a timeline at quote stage. Rush service is available for urgent deadlines.
Do you maintain terminology glossaries for ongoing projects?
Yes. For supply chain, regulatory, and corporate communication programmes, we maintain client-specific glossaries to ensure consistency across every document. This is especially important for manufacturing and pharmaceutical clients where terminology drift can cause compliance issues.
