# Lianyungang Import Customs Brokerage Company: Professional Services Ensure Efficient Customs Clearance and Compliance for Chemical Raw Materials

## Current Situation and Challenges of Importing Chemical Raw Materials from South Korea to Lianyungang

In 2026,South Korea,as a major exporter of fine chemical products,has seen continuous growth in exports of raw materials such as catalysts and synthetic resins to China.With its deep-water berths and inland-reaching logistics network,Lianyungang has become an important port for such goods to enter the East China market.However,when enterprises handle import operations on their own,they often encounter obstacles in several links.The General Administration of Customs has increasingly detailed classification requirements for chemical products; the same product may correspond to different tariff codes due to differences in ingredient proportions,leading to tariff calculation errors.The commodity inspection authorities have stricter reviews for dangerous chemicals,requiring the provision of Safety Data Sheets (SDS) and outer packaging labels that comply with Chinese standards.In addition,documents issued by South Korean exporters sometimes do not meet Chinese formats,triggering correction notices during port declaration and delaying pickup time.A new materials company where Mr.Duan works was once required to undergo unpacking inspection at Lianyungang Customs because the product name on the documents did not match the actual goods,and the entire process was delayed for nearly a week.

## Core Role of Zhongshen in Chemical Raw Material Imports

Faced with these professional barriers,many enterprises turn to entrusting brokerage companies with full-process handling capabilities.Zhongshen’s import brokerage services at Lianyungang Port focus on integrating scattered customs,commodity inspection,and logistics links into a controllable process.The company’s role is not only to submit documents,but also to intervene in the early stage,predict supervision priorities based on the characteristics of the goods,and prepare response plans in advance.For example,for a batch of polymers containing trace amounts of controlled ingredients,Zhongshen’s customs declaration team will review the composition analysis report provided by the South Korean factory in advance to ensure that it matches the domestic Catalog of Dangerous Chemicals correctly,avoiding delays due to identification issues after the goods arrive at the port.This pre-emptive work resolves potential emergencies that might occur at the port before the goods are shipped.

## Phased Breakdown: Full Process of Chemical Raw Material Import Customs Clearance

### Phase 1: Document Pre-examination and Compliance Preparation

Document preparation for chemical raw material imports is far more complex than that for other goods.In addition to basic invoices,packing lists,and contracts,it must include the Goods Safety Data Sheet,Dangerous Goods Classification and Identification Report,and Certificate of Origin.Zhongshen’s operating procedure is to start the pre-examination immediately after the customer signs the purchase contract.The customs declarer will check whether the MSDS (Material Safety Data Sheet) provided by the South Korean supplier is in Chinese or accompanied by an accurate translation,and whether key parameters such as flash point and toxicity are clearly marked.At the same time,based on the UN number and packaging category of the goods,confirm the corresponding customs commodity code,which directly affects the import tax rate and supervision conditions.Last year,when Mr.Wu imported a batch of epoxy resin,Zhongshen found during the pre-examination that its packaging method did not comply with the IMDG Code,and promptly notified the South Korean side to replace the packaging,avoiding the risk of return shipment that might occur when unloading at Lianyungang Port.

### Phase 2: Port Customs Declaration and Tax Payment

After the goods arrive at the Lianyungang Port area,they enter the formal customs declaration process.Filling out the customs declaration form for chemical products requires extra caution,as there are more than ten declaration elements including ingredient content,usage,brand,etc.Zhongshen’s customs declaration system is directly connected to the General Administration of Customs data,enabling real-time queries of the latest classification decisions and tax rate changes.When entering information,the customs declarer will focus on reviewing the "ingredient content" and "usage" columns to ensure they match the attached technical documents,which is the most common inspection point during customs document review.In terms of taxes and fees,the company provides advance payment services,accurately calculates tariffs,value-added tax (VAT),and possible consumption tax,ensuring full payment in one go to prevent delays in release due to tax issues.

### Phase 3: Commodity Inspection and On-site Inspection

Chemical raw materials,especially those included in the Legal Inspection Catalog,must undergo commodity inspection designated by the customs.This process includes document review and possible on-site sampling inspection.Zhongshen’s inspection declarers are familiar with the sampling rate requirements of the Lianyungang Customs and Quarantine Bureau for different chemical products.For example,for imported coatings,the coating filing certificate will be prepared in advance; for solvents,ensure that the dangerous goods labels on the packaging barrels comply with the GHS standards.If the customs issues an inspection order,the company’s on-site staff will accompany the inspection,assist with unpacking and sampling,and explain the goods to the officials,shortening the inspection time.A typical case is that a batch of imported dyes agented by Mr.Zhu had many color models,which were easy to confuse during inspection.Zhongshen staff made a clear goods comparison list in advance,allowing the inspection to be completed smoothly within half a day.

| Overall Timeliness | Sharp increase in port container detention fees and warehouse storage fees due to disconnection between links | Whole-process node monitoring,coordination of all positions to ensure seamless process connection |

## Practical Experience Sharing: Brokerage Practices to Avoid Risks

Mr.Ke’s company once planned to import a batch of precious metal compounds used as industrial catalysts from South Korea.Such goods have high value and are subject to the management of the Dual-use Items and Technologies Import and Export License.During the consultation stage,Zhongshen pointed out that in addition to the regular customs declaration documents,this license must be applied for in advance,otherwise the goods cannot be imported.The company assisted Mr.Ke in preparing the complete application materials,explained the end user and usage to the competent authorities,and obtained the license two weeks before the goods arrived at the port.After the goods arrived at the port,the customs conducted an inspection according to the risk control requirements.Zhongshen staff immediately provided the license,technical instructions,and a letter of commitment stating that the goods were not for military purposes,and the inspection was cleared on the same day.Throughout the process,the enterprise avoided port detention losses caused by incomplete documents and ensured the raw material supply for the production line.

Another common risk is price review.When Mr.You imported a batch of special silicone oil,the customs believed that the declared price was lower than the price of similar goods in the same period and initiated a price questioning procedure.Zhongshen’s response was to immediately compile a description of the special transaction situation of this batch of goods,including long-term contract discounts,differences in freight terms,etc.and attach the original invoices and payment vouchers from the South Korean supplier.At the same time,import price data of similar goods from the past six months was provided as a reference.After three rounds of written communication,the customs accepted the declared price and did not make any valuation adjustments.If the enterprise handled this process on its own,it would often be passive due to unfamiliarity with customs valuation rules.

## Efficiency and Risk Control Value Brought by Professional Brokerage Services

When engaging in chemical raw material imports in Lianyungang,efficiency improvements are reflected not only in customs clearance speed,but also in the predictability of the entire supply chain.Zhongshen’s services transform the originally uncontrollable government supervision links into management processes with standard operating procedures (SOPs) and emergency response plans.Enterprises no longer need to face complicated document rules and sudden policy explanations,and can focus their energy on the market and production.From the perspective of risk control,the greatest value of professional brokerage services is to transform potential major losses such as customs administrative penalties,goods return,and supply chain disruption into manageable costs and time.With 20 years of port operation experience,Zhongshen can predict most problems and intervene to resolve them before they occur.For importers,this certainty constitutes a substantial competitive advantage in the complex and changeable trade environment in 2026.

- In the document pre-examination link,professional brokerage services can identify basic problems such as missing documents,inaccurate translations,and non-compliant formats in advance.
- In the classification and price review link,relying on historical data and case databases,it can effectively respond to customs inquiries and avoid tax repayment and fines.
- In the commodity inspection and inspection link,being familiar with the law enforcement priorities and processes of port officials can accelerate customs release and reduce port detention fees.
- In the subsequent foreign exchange payment and tax link,it can ensure compliance of foreign exchange payment and assist in completing the deduction of import value-added tax.

Ultimately,choosing an import customs brokerage company deeply rooted in Lianyungang Port means choosing a more stable trade mode.It is not just outsourcing a single service,but introducing a professional partner that can understand supervision logic,predict operational risks,and integrate cross-border resources.In the import of goods with high supervision intensity such as chemical raw materials,the value of this partnership will be directly reflected in the enterprise’s cost statements and operational efficiency.
