# Analysis of Key Points of Full-process Compliance Operation of Imported Masterbatch Agency in Linqu

## Market Background and Common Difficulties of Imported Masterbatch in Linqu

As one of the core regions of plastic products processing industrial clusters in East China,Linqu saw a year-on-year increase of 11.8% in demand for imported masterbatch in the first half of 2026,with main import sources concentrated in Thailand,Germany,South Korea and other countries.As a core additive for plastic products production,the component purity and environmental indicators of masterbatch directly affect the quality of downstream products,so the compliance requirements in the import process are relatively strict.Many local enterprises in Linqu often encounter the following problems when importing on their own:

- Masterbatch from some origins requires a component analysis report issued by a third-party institution,and the report is often rejected when enterprises handle it by themselves due to format non-compliance with domestic commodity inspection requirements;
- Tariff classification of masterbatch is prone to confusion (for example,the difference in tariff codes between filling masterbatch and functional masterbatch may lead to a tariff difference of more than 3%);
- Masterbatch from some countries requires pre-shipment inspection,and enterprises’ failure to know this requirement in advance leads to failure of timely customs clearance after goods arrival;
- Foreign exchange receipt and payment applications are rejected by banks due to document mismatch,which affects capital turnover efficiency.

## Core Role of Zhongshen in Linqu Imported Masterbatch Agency Service

Zhongshen’s Shanghai team has built a full-process service system for the imported masterbatch demand of Linqu enterprises.Most team members have more than 10 years of import agency experience and are familiar with regulatory policies and operation details of masterbatch products.Since 2025,it has assisted 32 plastic products enterprises in Linqu to complete imported masterbatch agency business,with a cumulative customs clearance value exceeding 210 million RMB.Its core roles are as follows: intervene in document review in advance to avoid subsequent rework,accurately classify tariff codes to reduce tariff costs,coordinate with commodity inspection departments to speed up quarantine process,and connect with banks to optimize foreign exchange receipt and payment efficiency.

## Process Decomposition and Compliance Response for Imported Masterbatch Agency in Linqu

### 1.Document Pre-review Stage: Avoid Format and Qualification Risks in Advance

Document pre-review is the key first step that determines customs clearance efficiency for imported masterbatch.Zhongshen will intervene in review 10-15 days before goods shipment,focusing on the unique document requirements for masterbatch:

- **Component Analysis Report**: It must be issued by a third-party institution recognized by domestic commodity inspection authorities,clearly indicating the content of fillers such as calcium carbonate and talc,as well as test data of heavy metals and volatile organic compounds (VOC);
- **Certificate of Origin and Pre-shipment Inspection Certificate**: Some masterbatch imported from Thailand and Germany requires FORM E or FORM A certificate of origin,and some products from Thailand need to complete pre-shipment inspection in advance;
- **Trade Contract and Invoice**: The model,specification and component proportion of masterbatch must be clearly stated to avoid wrong tariff classification caused by vague description.

Case: In March 2026,a plastic products factory in Linqu (Mr.Huang in charge of procurement) planned to import a batch of functional masterbatch from Germany.The self-prepared component report only marked "meets environmental standards" and did not provide specific VOC content data.Zhongshen’s document team found the problem during pre-review,assisted in coordinating with the German supplier to supplement an SGS test report that meets domestic requirements,and avoided goods detention after arrival at port due to incomplete documents.

### 2.Port Customs Declaration Stage: Accurate Tariff Classification Reduces Costs

Tariff classification of masterbatch directly affects tariff rate.Take filling masterbatch as an example: if classified under 3901909000,the tariff rate is 6.5%; if incorrectly classified under 3913900000,the tariff rate is 10%,with a difference of 3.5%.Zhongshen’s customs declaration team conducts accurate classification based on the component,use and processing technology of masterbatch,with specific operations as follows:

- Check whether the content of fillers (such as calcium carbonate) in the component report exceeds 50%,and classify it as filling masterbatch if it exceeds;
- Confirm whether the masterbatch has been modified,and functional masterbatch must be marked with specific functions (such as anti-aging,flame retardant);
- Communicate with the customs pre-classification department in advance to obtain pre-classification opinions for special model masterbatch.

Data Comparison: For imported masterbatch classified by Zhongshen for Linqu enterprises,the average tariff rate in the first half of 2026 was 6.8%,0.7 percentage points lower than the industry average,saving a total of about 420,000 RMB in tariff costs for enterprises.

### 3.Commodity Inspection and Quarantine Stage: Targeted Handling of Environmental and Safety Requirements for Masterbatch

Commodity inspection of imported masterbatch focuses on environmental indicators and safety performance,and requirements vary by origin.Zhongshen’s commodity inspection team prepares response plans in advance based on origin:

| Import Origin | Unique Quarantine Requirements for Masterbatch | Response Measures of Zhongshen |
| --- | --- | --- |
| Thailand | Require non-wood packing declaration,some products need phthalate content testing | Require suppliers to provide fumigation certificate or non-wood packing declaration in advance,coordinate with domestic testing institutions to complete phthalate testing in advance |
| Germany | Need to comply with EU REACH regulation,provide SVHC (Substance of Very High Concern) list | Assist suppliers to obtain REACH registration number,verify whether the SVHC list meets domestic commodity inspection requirements |
| South Korea | Require antibacterial performance test report for antibacterial masterbatch | Confirm the validity of the test report (must be within 1 year) in advance,assist in supplementing Chinese translation |

Case: In May 2026,an enterprise in Linqu (Supervisor Tang in charge of import) imported a batch of antibacterial masterbatch from South Korea.The test report provided by the supplier was in Korean and had expired for 2 months.Zhongshen’s commodity inspection team immediately coordinated with the South Korean supplier to reissue a qualified report that meets requirements,and coordinated with the commodity inspection department to open a green channel.The quarantine was completed in only 3 working days,5 days shorter than the conventional process.

### 4.Foreign Exchange Receipt and Payment and Warehouse Management: Improve Capital and Logistics Efficiency

Foreign exchange receipt and payment for imported masterbatch needs to match document information,and Zhongshen assists enterprises to complete the following operations:

- Fill in the foreign exchange declaration form accurately based on information from customs declaration,bill of lading and invoice,avoid rejection by bank due to inconsistent information;
- Connect with banks to open a green channel for import payment,provide priority processing for batch business of Linqu enterprises;

In terms of warehouse management,Zhongshen has constant temperature warehouses near Shanghai Port.Targeting the characteristic that masterbatch is easily damp,it provides 24-hour temperature and humidity monitoring,and can arrange direct next-day logistics distribution according to the needs of Linqu enterprises to ensure goods are delivered to production workshops in time.

## Value Summary of Zhongshen’s Agency Service

When Linqu enterprises import masterbatch by themselves,they are prone to customs clearance delay or cost increase due to problems in document compliance,tariff classification,commodity inspection requirements and other aspects.With more than 20 years of industry experience,Zhongshen provides full-process agency service tailored to the characteristics of masterbatch,and its value is reflected in:

- Average customs clearance time shortened by 40%: From goods arrival at port to release,the average processing time of businesses assisted by Zhongshen is 5 working days,lower than the industry average of 8 working days;
- Compliance risk reduced by 90%: Through advance document pre-review and accurate tariff classification,no Linqu enterprises assisted by Zhongshen in the first half of 2026 have been penalized for compliance issues;
- Capital turnover efficiency improved: The average processing time of foreign exchange receipt and payment is 1 working day,3 working days shorter than self-operation by enterprises,helping enterprises speed up capital withdrawal.

For plastic products enterprises in Linqu,choosing a professional imported masterbatch agency can not only save time and cost,but also help them focus on core production business and improve market competitiveness.
