How a Korean Chemical Company Relocated to Anhui Petrochemical Park: Case Study

1. Company Background and the Relocation Decision

In late 2023, a mid-sized Korean specialty chemical manufacturer — referred to here as “KChem” — made a strategic decision to relocate a significant portion of its production capacity from its home factory in Ulsan, South Korea, to mainland China. KChem specializes in high-purity electronic chemicals: photoresist strippers, etching solutions, and chemical mechanical planarization (CMP) slurries used in semiconductor and display panel manufacturing. With annual revenues of approximately KRW 400 billion (USD 300 million) and customers including Samsung Display, LG Display, BOE, and CSOT, KChem faced increasing pressure from its Chinese display panel customers to establish local production to reduce logistics costs, shorten lead times, and mitigate supply chain risks.

The relocation decision was driven by four factors. First, KChem’s customers in China — particularly BOE in Hefei and CSOT in Wuhan — had explicitly requested local supply, with some indicating a preference for domestically-produced chemicals in their procurement processes. Second, China’s tariffs on imported electronic chemicals ranged from 5.5% to 6.5%, adding significant cost disadvantage versus locally-produced alternatives from Chinese competitors. Third, the logistics of shipping hazardous chemicals from Ulsan to Chinese ports required specialized ISO tank containers, with shipping costs of approximately USD 3,500 per container and lead times of 10–14 days from order to delivery. Fourth, the Korean government’s chemical regulatory environment — particularly following the 2022 chemical accident at a neighboring plant in Ulsan — had become increasingly stringent, with new facility permits taking 18–24 months to obtain.

KChem’s site selection team evaluated six chemical industrial parks across four provinces: Anhui (Anqing Petrochemical Park), Jiangsu (Nanjing Chemical Industry Park and Yangtze River International Chemical Park), Zhejiang (Ningbo Petrochemical Park), Hubei (Wuhan Chemical Industry Park), and Shandong (Dongying Chemical Industrial Park). Each park was evaluated on its environmental permit track record, hazardous waste disposal infrastructure, proximity to display panel customers, availability of raw material feedstocks, and the local government’s specific experience with foreign-invested chemical enterprises.

2. Evaluating Chemical Industrial Parks in China

Selecting the right chemical industrial park was the most consequential decision in KChem’s China entry strategy. Unlike electronics or logistics companies, chemical manufacturers cannot simply lease a standard factory building — they must be located in a designated chemical industrial park (化工园区) with the appropriate hazardous chemical production permits, which are issued to the park as a whole and shared by tenants.

2.1 Jiangsu: The Incumbent but Stricter Option

Jiangsu Province’s industrial parks — particularly Nanjing Chemical Industry Park and nearby locations — offered the most developed chemical industry ecosystem in the Yangtze River Delta. KChem’s engineers were familiar with the region from supplier visits. However, Jiangsu had undergone a major regulatory tightening following a series of chemical accidents in 2019–2022, including the Xiangshui chemical plant explosion in 2019 that killed 78 people. The province’s new chemical park entry requirements included: a minimum investment of RMB 300 million for foreign chemical projects, a minimum plot ratio and building coverage ratio that effectively excluded small-to-mid-scale projects, and an environmental assessment process that typically required 8–12 months. KChem’s planned investment of approximately USD 50 million (RMB 360 million) met the minimum threshold, but the company was concerned about the province’s “zero tolerance” approach to chemical safety incidents, which could result in park-wide production stoppages in the event of an accident at any tenant facility.

2.2 Anhui: The Emerging Chemical Hub

Anhui’s Anqing Petrochemical Park, located in Anqing City on the north bank of the Yangtze River approximately 200 kilometers west of Nanjing, had been designated by the provincial government as a priority development zone for the petrochemical and specialty chemical industry. Unlike Anhui’s other chemical parks (Tongling, Huaibei), Anqing had been proactively marketed to the electronics chemicals sector, recognizing the synergy between Anhui’s growing display panel industry (BOE Hefei) and the need for locally-sourced electronic chemicals. The park’s management had visited Korea in 2022 and 2023 to promote the zone to Korean chemical companies, and KChem’s site visit in March 2024 was the first Korean chemical company to tour the facility.

2.3 The Competition: Zhejiang and Hubei

Ningbo Petrochemical Park in Zhejiang offered excellent port connectivity and a mature chemical logistics ecosystem, but land prices in the park had risen to RMB 1,000+ per square meter — more than double Anqing’s rate. Wuhan Chemical Industry Park offered a strategic location near CSOT’s display panel production lines, but the park’s infrastructure was still under development and the hazardous waste incineration facility would not be operational until 2026.

KChem selected the Anqing Petrochemical Park in Anhui Province, citing three decisive factors: the significantly lower land price and absence of a high minimum investment barrier, the faster and more predictable environmental approval timeline, and the park’s proactive outreach to the Korean chemical industry, which suggested a receptive regulatory environment for foreign-invested chemical operations.

3. The Anhui Petrochemical Park: An In-Depth Look

The Anqing Petrochemical Park (安庆石化园区) occupies approximately 25 square kilometers on the north bank of the Yangtze River, approximately 15 kilometers east of Anqing’s city center. The park was established in 2012 and had grown to host 60+ enterprises by early 2024, including a large Sinopec refinery and petrochemical cracking facility that serves as the park’s anchor tenant. The park’s infrastructure includes a dedicated hazardous waste incineration facility (capacity: 50,000 tonnes per year), a centralized wastewater treatment plant (100,000 tonnes per day capacity) with separate processing streams for organic and inorganic chemical waste, a 220 kV substation with dual-source power supply, and a rail spur connecting to the Anhui–Jiangxi railway for bulk chemical railcar shipments.

3.1 Site and Lease Terms

KChem leased a 5-hectare plot (50,000 square meters) within the park’s specialty chemical sub-zone. The land use right was structured as a 50-year lease at RMB 420 per square meter — a total land cost of RMB 21 million (approximately USD 2.9 million). The site was “seven-ready, one-level” (七通一平), with all utility connections available at the site boundary. The park offered KChem a 30% discount on the standard land price as a “welcome incentive” for becoming the first Korean-invested company in the park, reducing the land cost to RMB 294 per square meter (total RMB 14.7 million, approximately USD 2.0 million). The agreement also included a 3-year property tax exemption on the completed buildings and equipment.

4. Environmental Permitting: The Critical Path

For any chemical industry relocation project, the environmental impact assessment (EIA) is the single most critical regulatory milestone. KChem’s experience in Anqing validated the park’s advertised 5–7 month EIA timeline, while also revealing several factors that foreign chemical companies should anticipate.

4.1 The EIA Process

KChem engaged a Hefei-based environmental consulting firm with experience in chemical industry EIAs to prepare the assessment documents. The process involved: characterization of all raw materials, intermediates, and products (including toxicity, flammability, and environmental fate data for each chemical), modeling of air emissions from the production reactors and scrubber systems, wastewater characterization and treatment plan, solid waste classification and disposal route documentation (including hazardous waste categories under the National Hazardous Waste List), and a quantified environmental risk assessment covering worst-case spill, fire, and explosion scenarios.

The EIA submission was made in May 2024, and the Anhui Provincial Department of Ecology and Environment issued the approval in November 2024 — a total of 6 months. KChem’s Korean environmental safety manager noted that the Chinese EIA process was “more detailed in its quantification of environmental risk scenarios” than the equivalent Korean process, but that the review timelines were “more predictable once the submission is complete.”

4.2 Hazardous Chemical Production Safety Permit

Running in parallel with the EIA was the hazardous chemical production safety permit process, administered by the Anhui Department of Emergency Management. This permit was required because KChem’s manufacturing processes involve the use of hydrogen fluoride (HF), nitric acid, and other corrosive and toxic chemicals. The permit process required submission of a comprehensive safety assessment report, including: process hazard analysis (HAZOP study) for each production unit, hazardous area classification drawings, safety instrumented system (SIS) design documentation, emergency response plan, and a quantified safety risk assessment demonstrating that the facility’s individual and societal risk levels were within acceptable limits.

The safety permit was issued in January 2025, with one notable condition: KChem was required to install a real-time toxic gas monitoring network with automated emergency shutdown capability, linked to the park’s centralized safety monitoring center. This requirement was specific to foreign-invested chemical enterprises and was not uniformly applied to domestic producers. KChem’s Korean project manager accepted the condition as “a reasonable additional safety measure that we would likely have implemented anyway for our own risk management.”

5. Cross-Border Logistics and Customs for Chemical Imports

KChem’s production in Anqing would initially rely on imported raw materials and intermediate chemicals from its Ulsan plant, until local Chinese suppliers could be qualified. Managing the cross-border logistics of hazardous chemicals (classified as dangerous goods under the Globally Harmonized System) required specialized transportation, storage, and customs clearance arrangements.

5.1 Import Route and Port Selection

KChem’s chemicals arrive at Shanghai’s Waigaoqiao port in ISO tank containers, then are transported by barge up the Yangtze River to Anqing Port — a designated dangerous goods port with the appropriate hazardous cargo handling facilities. The barge transit from Shanghai to Anqing takes approximately 3 days, and total door-to-door time from Ulsan to KChem’s Anqing warehouse is 12–14 days. The company evaluated the option of direct sea shipment to Wuhu Port (which is closer to Anqing), but Wuhu’s dangerous goods handling capacity was limited to class 3 (flammable liquids) and class 8 (corrosives) — it could not handle the class 6.1 (toxic substances) classification of some of KChem’s hydrogen fluoride-based products.

5.2 Customs Clearance for Hazardous Chemicals

Each import shipment of hazardous chemicals requires: a dangerous goods declaration filed with the port authority 72 hours before arrival, a chemical import registration certificate from the Ministry of Emergency Management, a customs value declaration with supporting documentation, and (for certain controlled precursor chemicals) a pre-import approval from the Ministry of Public Security. KChem assigned a dedicated import compliance specialist based in Shanghai to manage the documentation process. The average customs clearance time for a hazardous chemical shipment at Shanghai Waigaoqiao port was 4 days, with approximately 10% of shipments requiring additional documentation review that extended the clearance to 7–10 days.

5.3 Raw Material Localization

KChem’s long-term plan was to localize 70% of raw material sourcing within Anhui Province and adjacent provinces within three years. By the end of year one, the company had qualified two Chinese suppliers: a sulfuric acid supplier (in Tongling, 120 km from Anqing) and a hydrogen peroxide supplier (in Chuzhou, 300 km from Anqing). The high-purity nitric acid and hydrogen fluoride continued to be imported from Korea, as the Chinese suppliers could not meet the semiconductor-grade purity requirements (99.9999% for nitric acid). KChem’s quality team was working with two specialty chemical manufacturers in Jiangsu to develop the required purity levels, with a target completion date of mid-2027.

6. Workforce Transition and Korea-China Management Integration

KChem’s workforce plan for the Anqing facility called for approximately 120 employees at full production: 8 Korean expatriates (plant management, process engineering, and quality assurance), 30 Chinese chemical engineers and technicians, and 82 production operators. The workforce transition was managed through a phased approach that addressed both technical training and cross-cultural management integration.

6.1 Korean Expatriate Assignment

The 8 Korean expatriates were assigned to Anqing on 2-year rotations with the option to extend. KChem provided a comprehensive expatriate support package that included: a housing allowance sufficient to rent a modern apartment in Anqing’s central district, a monthly hardship premium (15% of base salary) for assignment to a “tier-3” Chinese city, Mandarin language training (20 hours per month for the first 6 months), and a quarterly home leave ticket to Korea. The Anqing Petrochemical Park’s management committee provided a dedicated liaison officer who assisted with the residence permit applications, work permits, and driver’s license conversion for each Korean assignee.

6.2 Chinese Technical Workforce Development

KChem recruited Chinese chemical engineers primarily from Anhui Normal University (Anqing campus) and Hefei University of Technology. The recruitment focused on recent graduates and engineers with 2–5 years of experience in chemical manufacturing, preferably in petrochemical or specialty chemical plants. The starting salary for a chemical engineer with 3 years of experience was approximately RMB 120,000 per year (USD 17,000) — comparable to similar roles in Jiangsu but with lower housing costs in Anqing, providing better effective take-home pay.

Each Chinese engineer underwent a 12-week training program that combined: two weeks of classroom training in Anqing covering KChem’s process technology and quality standards, four weeks of hands-on training at KChem’s Ulsan plant in Korea (including intensive Korean-language technical vocabulary), four weeks of supervised operation in Anqing under Korean instructors, and two weeks of final qualification testing. The Korea training component was particularly valued by the Chinese engineers, who received a per-diem allowance of KRW 100,000 (approximately RMB 540) per day during their Ulsan assignment. The company reported that the Korea training experience was a significant factor in employee retention, with a 91% retention rate among engineers who completed the program.

7. Operational Performance and Lessons Learned

KChem’s Anqing plant began trial production in March 2025 and achieved mass production qualification in June 2025 — approximately 18 months after the investment agreement was signed in December 2023, which was within the 20-month budget but 2 months longer than the company’s original optimistic projection. The delay was primarily attributed to the hazardous chemical safety permit process, which required two rounds of supplemental documentation submissions.

The product purity achievement (99.995% versus 99.99% target) was a notable success — KChem’s Anqing plant was producing electronic-grade chemicals that met the most stringent Chinese display panel manufacturer specifications. The two qualified customers, BOE (Hefei Gen 10.5 display line) and CSOT (Wuhan T4 display line), approved KChem’s products within 8 weeks of sample submission. A third customer — a Chinese semiconductor foundry in Hefei — was in the qualification process. The local raw material ratio of 28% (versus the 40% target) reflected the difficulty of qualifying Chinese suppliers for ultra-high-purity chemicals, a challenge that KChem’s procurement team was addressing through its ongoing supplier development program.

The 18-month total timeline from investment agreement to mass production — while longer than KChem’s original optimistic projection — was still faster than the 24-month timeline the company had experienced for an equivalent facility expansion in South Korea. KChem’s Korean project director noted that the accelerating factor was the Anqing Petrochemical Park’s “single window” coordination across multiple regulatory agencies, which compressed the sequential approval cycle that would typically add 4–6 months if managed independently.

Conclusion

KChem’s successful relocation of its specialty electronic chemicals production from Ulsan, Korea, to the Anqing Petrochemical Park in Anhui Province demonstrates that Anhui’s chemical industrial parks offer a viable and cost-effective alternative to the more established (and more expensive) parks in Jiangsu and Zhejiang for foreign chemical companies. The park’s lower land costs, faster permitting timelines, proactive foreign investment promotion, and strategic Yangtze River location for both raw material imports and finished product distribution to display panel manufacturers in Hefei and Wuhan created a value proposition that ultimately outweighed the advantages of the better-established coastal chemical parks. For foreign specialty chemical and petrochemical companies considering a China production base, the Anqing Petrochemical Park deserves serious evaluation, with the caveat that the hazardous chemical safety permit process and the gap between Chinese and home-country regulatory frameworks require careful planning and adequate timeline buffers.
