Technical documentation for Korea starts from a legal floor. A foreign equipment or materials supplier selling into a Korean fab needs Korean-language safety data sheets as a statutory obligation, plus installation and operation manuals, maintenance procedures, spare parts lists, training material, change-control documents, and SEMI conformance reports Korean engineers can read without a dictionary. The rest is commercial, and English-only packages stall qualification.

Documentation sits early in the entry sequence mapped in the guide to Korea semiconductor market access for foreign suppliers, and it is the deliverable most often deferred until a fab asks for it. The request then carries a deadline, and a Korean document set takes months to build. Treat the regulatory position as current to August 2026.

What Does Korean Law Actually Require in Korean?

The hard legal requirement covers chemical safety documentation. Under Article 110 of Korea’s Occupational Safety and Health Act, a manufacturer or importer of a chemical meeting the GHS classification criteria must prepare a material safety data sheet and file it with the Ministry of Employment and Labor before manufacture or import. Bergeson and Campbell reported that the obligation, created by the 2019 amendment, took effect on 16 January 2021. Article 111 requires the supplier to pass the sheet down to the recipient, and Article 114 requires the employer to post it where workers see it.

Both the sheet and the container label must be in Korean under the Ministry’s standards for classification, labeling and material safety data sheets, with proper nouns such as chemical names and your contact details permitted in English. ChemSafetyPro states the same position: a filing in English alone is non-compliant.

That standard moves. REACH24H reported Notice No. 2025-50, issued on 6 August 2025 and effective the next day, which overhauled Section 15 of the MSDS format, and legacy templates expired on 30 June 2026. Korea’s National Law Information Center then records Notice No. 2026-26, in force from 24 April 2026, whose published scope covers foreign-language warning labels and mixture entries, and whose supplementary provision sets an effective date and nothing else. Sheets already rebuilt to the 2025-50 format stand under it, so the label clause is your check item.

Enforcement turns on the Korean-language point. CIRS Group reported that in late November 2025 KOSHA issued a rectification notice after reviewing a large volume of submitted sheets, listing recurring defects: unclear importer details, incomplete toxicological information, product names that did not match Korea’s chemical registration records, and sheets not in Korean. Recipients had to resubmit by 16 January 2026, after which KOSHA moved to mandatory enforcement.

That date closed the last of the phased grace periods. The Ministry announced on 11 December 2025, in coverage carried by the Korean environmental daily Hwankyung Ilbo (환경일보), that from 16 January 2026 every safety data sheet in circulation must carry the submission number issued at filing, and that any trade-secret substitution must use pre-approved alternative data. The exemption had been phased out by tonnage band since 2022, and the band below one tonne a year, where many specialty semiconductor chemicals sit, was the last to lose it.

A company with no Korean legal entity cannot submit to KOSHA directly: Article 113 lets an overseas manufacturer appoint a qualified Korea-based person to file in place of the importer. Article 112 sets the trade-secret route, an approval to write authorized alternative names and contents into the sheet, filed on Enforcement Rule Form 63 through KOSHA’s material safety data sheet system (물질안전보건자료시스템) and renewed at least 30 days before it lapses. ChemSafetyPro describes it as prior approval, so schedule it. Both recur in chemical registration under K-REACH, which materials suppliers should run alongside this one.

Which Korean Certifications Put Documentation on the Critical Path?

Equipment runs on a separate track, and the statute names the routes. Article 84 requires safety certification (안전인증), the KCs mark, from manufacturers and importers of designated hazardous machinery, administered by KOSHA. Article 89 requires a self-declaration of conformity (자율안전확인신고) for a lower-risk designated list, with the declarant keeping the evidence on file. Article 93 adds periodic safety inspection (안전검사) for machinery already in service. TUV Rheinland’s guidance notes that the certification route adds an initial factory audit and annual follow-up inspections.

Whether your tool falls inside a KCs category is answerable in month one of Korea planning. Article 74 of the Act’s Enforcement Decree enumerates the Article 84 list, and it names general industrial machinery: presses, shears and benders, cranes, lifts, pressure vessels, rollers, injection molding machines, aerial work platforms and gondolas, plus protective devices and personal protective equipment. Semiconductor process tools are absent as a category, so what catches fab suppliers is the component level. Pressure vessels and explosion-proof electrical equipment sit on that list, and Enforcement Decree Article 78 puts fixed local exhaust ventilation, industrial centrifuges and industrial robots on the Article 93 inspection list for machinery already installed.

Separately, the Korean Agency for Technology and Standards runs the KC mark scheme, introduced on 1 July 2009 to integrate thirteen mandatory certification marks then operated by the Ministry of Knowledge Economy and the Ministry of Labor, per the KATS material on ANSI’s Standards Portal and the US Commerce country commercial guide for Korea. A Korean user manual with operating instructions and safety warnings forms part of the KC application file, putting translation upstream of certification.

Two further filings sit on the customer’s side of the line and reach back to you for data: the hazard prevention plan (유해위험방지계획서) an employer submits under Article 42 when installing or relocating designated production equipment, and the process safety management report (공정안전보고서) a workplace running designated hazardous facilities files under Article 44. The supplier’s job is to hand over the drawings, interlock descriptions, chemical inventories and operating parameters that go into them, in Korean, on the fab’s schedule, which is why a set built for a Western customer arrives incomplete.

The commercial set is larger than the legal one, and Korean fabs ask for most of it during vendor review. A package for a process tool covers installation and facilities requirements, an operation manual, maintenance procedures with intervals, a spare parts list with part numbers and stocking levels, training material, your change-notification process and the safety conformance file.

That conformance file is where SEMI standards do the work. SEMI S2, the environmental, health and safety guideline for semiconductor manufacturing equipment, stands at the S2-0724E edition in SEMI’s standards store as of August 2026. Intertek’s guidance on the preceding 0821 edition, which ran to 28 sections and 5 appendices, identifies Section 9 as documents provided to the user and Section 10 as hazard alert labels; confirm the numbering against the 0724E text before you index against it. SEMI S8 covers ergonomics, and SEMI S13 sets out what belongs in the operation, maintenance, installation and safety manuals. Intertek and TUV SUD both note that most fabs expect an S2 report with new equipment, and that S2 and S8 language appears in purchase contracts.

Language allocation across that set is a commercial judgment rather than a statutory rule. Safety data sheets and on-tool hazard labels go into Korean because the law and the workplace demand it, and operation, maintenance and training material follow because the people using them are technicians on a rotating shift. S2 and S8 evaluation reports are still delivered in English, though SEMI announced a Korean translation of S2-0724 in the August 2025 issue of its Standards Watch newsletter. Proposal packages should be Korean or bilingual, because a committee reads them.

Technical documentation for Korea has a delivery address, and that address is a portal. A foreign supplier enters a large fab’s system through vendor registration (협력회사 등록). SK hynix takes new suppliers through its shared growth portal, where a company files its particulars and submits an evaluation request that purchasing and the relevant technical group review before approval. Samsung Electronics runs an equivalent open sourcing route and, under its published supplier code of conduct, requires suppliers to disclose their labor, safety, health and environmental management status. Your material goes into fixed templates and through an EHS screen, so a package assembled fresh for each request will not survive.

Who Should Translate Technical Documentation for Korea?

A translator with semiconductor process experience, followed by technical review from a Korean-speaking engineer who has worked with the tool. Machine translation belongs upstream, as a first pass that specialist corrects line by line, and has no place in the delivered safety file: liability under Articles 110 and 111 attaches to a named company, KOSHA reviews submissions, and a mistranslated exposure limit is a workplace incident waiting for a court to assign responsibility.

Terminology is where most foreign suppliers lose credibility. Korean semiconductor engineers use English loanwords for much of the process vocabulary, so etch, chamber, CMP, purge and recipe stay transliterated while procedural and safety language becomes fully Korean. A translator without industry exposure renders those loanwords as pure Korean coinages, which reads to a fab engineer the way an amateur-drafted contract reads to a lawyer.

Build a bilingual glossary before volume translation begins. A few hundred approved term pairs, reviewed by your distributor’s engineering staff, will govern every document you produce. Attach it to the contract and require a translation memory you own.

How Do You Keep Korean and English Documentation in Sync for a Korean Fab Audit?

With document control, applied to the Korean file with the discipline you apply to the English original. Every engineering change notice generates a delta in two languages, and a Korean version two revisions behind the English creates a finding during a fab audit and an argument during a warranty claim.

Run a simple control matrix: document identifier, revision, language, issue date, translator, technical reviewer, approval. Tie each Korean revision to its English source revision, and decide in advance which changes trigger retranslation.

If your Korean distributor produces the documentation, the agreement should say who owns the glossary, the memory and the translated files at termination. Suppliers who skip that clause find during a partner transition that a decade of Korean documentation belongs to the company they are leaving. Raise it while you are still selecting a Korean distributor.

What Does Korean Technical Documentation Cost and How Long Does It Take?

Pricing units vary by vendor: Korean domestic agencies commonly quote by manuscript page (원고지) or A4 page, while specialist practices quote per word or per character. One published specialist rate card, that of Korean Consulting and Translation Service, the practice of American Translators Association member Steven S. Bammel and current under a 2025 to 2030 copyright, puts premium English into Korean at USD 0.22 to 0.36 per source word, Korean into English at USD 0.12 to 0.19 per Korean character, and notes that difficulty alone can move a quote by 30 to 50 percent. Semiconductor work sits at the upper end of that band before the engineering reviewer’s time, and FrameMaker source or CAD callouts add a desktop publishing layer.

Lead time matters more than unit price: safety data sheets need Korean preparation, review and KOSHA submission before import. MPR Korea Certification puts KCs safety certification at three to four months without a factory audit and four to five months with one, plus one to two months for product testing, and states that those figures assume the documents are already available, which for a foreign supplier means already translated. MPR also notes that KOSHA publishes its guidance in Korean only, so an applicant with no Korean-reading staff carries a monitoring burden on top of the filing.

The trade-secret route carries its own published clock. Under Article 162 of the Act’s Enforcement Rule, KOSHA decides a non-disclosure approval or extension within one month of application and may push that deadline by up to ten days for unavoidable reasons. Article 112-2 of the Act gives an applicant 30 days from the result to file an objection, decided within 14 days under the procedure in Enforcement Rule Article 163. A supplier who starts documentation at the fab’s request has inserted months of avoidable delay into a fab qualification process that runs twelve to eighteen months at best.

Sequence the work: safety data sheets and hazard labels first because they are legally gated, the proposal package second because it carries the sales conversation, manuals third because installation needs them. Budget it inside the qualification line rather than the marketing line, because it is a condition of entry into one of the world’s largest semiconductor manufacturing bases.

Why Does Documentation Quality Read as a Proxy for Seriousness to a Korean Fab?

Because it is the first evidence a Korean procurement committee has that you will still be supporting the tool in year seven, and it is read by people who never meet your sales team.

A Korean procurement review reads four signals. Completeness tells them whether you have supported this product elsewhere. Korean-language depth tells them how much of your organization is committed to the market rather than to the deal. Terminology consistency tells them whether a professional handled the work. Revision discipline tells them what your change management will look like at two in the morning.

Frequently Asked Questions

Is a Korean-language safety data sheet legally required? Yes. Article 110 of the Occupational Safety and Health Act requires manufacturers and importers of GHS-classified chemicals to file an MSDS with the Ministry of Employment and Labor before manufacture or import, and the Ministry’s classification and labeling standards require the sheet and the label in Korean, with proper nouns such as chemical names allowed in English.

Can I use machine translation for Korean technical documentation? Use it as an internal first pass only, never as the delivered document for safety, installation or maintenance content. Liability under Articles 110 and 111 sits with your company, KOSHA reviews submitted sheets and issued a rectification notice in November 2025 according to CIRS Group, and Korean engineers know raw output on sight.

Do SEMI S2 and S8 reports need to be in Korean? Korean fabs generally accept S2 and S8 evaluation reports in English, since EHS teams read those international deliverables routinely. SEMI announced a Korean translation of S2-0724 in its Standards Watch newsletter in August 2025, so expect that to broaden. What needs Korean today is what people use on the floor: safety data sheets, hazard labels, maintenance procedures and training material.

Documentation is the cheapest credibility a foreign supplier can buy in Korea and the most expensive thing to fix once a fab has formed an impression. What I do at Inquivix Technologies is the judgment layer ahead of the production work: which documents are legally gated, which are commercially gated, what language each belongs in, and the order they have to exist in. The execution behind it is set out in the company’s guide to entering the Korean semiconductor market. To see how your set reads to a Korean committee, reach Joon K Lee at joon@joonklee.com.
