# Full-Process Solution for Nantong Chemical Export Agency

## Market Status and Common Challenges of Nantong Chemical Exports

Nantong’s chemical exports showed a significant growth trend in 2026.According to data from the local foreign trade association,in the first 8 months of this year,Nantong’s exports of chemical raw materials to Southeast Asian countries such as Vietnam,Thailand and Malaysia increased by 18% year-on-year,with particularly prominent demand for products such as organic chemical raw materials and synthetic resins.However,many Nantong enterprises still face multiple challenges in the export process: some enterprises have their documents returned by customs because they fail to update the environmental protection certification of the target country in time; some hazardous chemicals are detained due to non-compliant packaging that does not meet the requirements of Southeast Asian ports; other enterprises see their export tax refund cycle extended to more than 30 days due to unclear export contract clauses.

## Core Value of Zhongshen’s Nantong Chemical Export Agency Services

Zhongshen has been deeply engaged in the foreign trade agency industry for more than 20 years.In view of the characteristics of Nantong’s chemical exports and combined with the latest trade policies of Southeast Asian countries in 2026,it provides enterprises with full-process customized agency services.The core value is reflected in three aspects: first,accurately matching the policy requirements of the target country to avoid shipment delays caused by compliance issues; second,integrating resources such as customs declaration,transportation and warehousing to improve overall efficiency; third,optimizing the tax refund process to accelerate the capital turnover of enterprises.

## Disassembly of Core Service Modules of Nantong Chemical Export Agency

### 1.Document Compliance Service: Matching Certification Requirements of Southeast Asian Countries

In 2026,Vietnam and Thailand added two key requirements for documents of imported chemicals: first,a **Life Cycle Assessment Report** is required,and second,hazardous chemicals need to be attached with **2026 Revised Globally Harmonized System of Classification and Labelling of Chemicals Labels**.Some Nantong enterprises have had their labels returned due to non-compliant content as they failed to pay attention to policy updates.

Manager Duan of Zhongshen’s document team will connect with enterprises in advance to obtain product parameters,and formulate differentiated document plans for different target countries:

- Vietnam market: assist in preparing Life Cycle Assessment reports and product safety certificates issued by third-party testing institutions recognized by the Ministry of Industry and Trade of Vietnam to ensure that the report content complies with local environmental standards;
- Thailand market: check the accuracy of the Thai translation of GHS labels to ensure consistency with the Hazardous Chemical Label Specification issued by the Ministry of Industry of Thailand in 2026;
- All documents are submitted to the agency customs clearance team of the target country for pre-audit 3 working days in advance to avoid delays caused by format issues.

### 2.Customs Clearance Service: Responding to Special Supervision Measures of Southeast Asian Ports

![2026 Tips for Improving Nantong Chemical Export Customs Clearance Efficiency](https://cndpic.sh-zhongshen.com/uploads/tradepics/tXxGzFLPiiP1I.webp)

In 2026,Bangkok Port in Thailand and Ho Chi Minh Port in Vietnam implemented a dual-track system of **pre-declaration + on-site inspection** for imported chemicals,covering the physical form of products and whether the packaging complies with the Southeast Asian Chemical Transport Packaging Specification.In addition,the anti-dumping duty rate imposed on organic chemicals by some countries is adjusted once a year.If Nantong enterprises fail to update the tax rate information in time,the customs clearance cost may increase by 10% to 15%.

Zhongshen’s customs clearance team’s response plan:

- Obtain the latest anti-dumping duty list of the target country 10 working days in advance.If the product is included in the list,assist enterprises to prepare surrogate country price certification materials to avoid paying excessive tariffs by mistake;
- Maintain daily communication with local customs in Thailand and Vietnam,complete pre-declaration for chemical products of Nantong enterprises in advance,and arrange dedicated personnel to follow up during on-site inspection,with the average customs clearance cycle 2 days shorter than the industry average;
- For liquid chemicals,confirm the compliance of port storage tanks in advance to avoid cargo detention at the port caused by storage tanks that do not meet environmental protection requirements.

### 3.Export Tax Refund Service: Accelerating Capital Turnover of Nantong Chemical Enterprises

Export tax refunds for Nantong chemical enterprises are often delayed due to problems such as "inconsistent information between customs declaration forms and VAT invoices" and **unclear export contract clauses**.In 2026,the State Taxation Administration’s audit focus for chemical export tax refunds is on "the matching degree between products and HS codes on customs declaration forms".Some enterprises have their tax refund cycle extended to more than 30 days due to incorrect HS code classification.

Optimization measures of Zhongshen’s tax refund team:

- Establish a green communication channel with the local tax bureau in Nantong,check HS codes and relevant document information in advance to ensure that the product name,quantity and specification on the customs declaration form are completely consistent with those on the VAT invoice;
- Supplement key information required for tax refunds such as "product specifications,packaging methods,transport clauses" for export contracts of Nantong enterprises to avoid audit rejection due to missing contract clauses;
- Automatically match the latest 2026 export tax refund policies through the internal system,shortening the average tax refund arrival time to within 15 working days,7 days faster than the industry average.

| Export Link | Average Cycle for Nantong Enterprises’ Self-Export | Average Cycle for Zhongshen Agency | Efficiency Improvement Rate |
| --- | --- | --- | --- |
| Document Preparation and Pre-audit | 7-10 working days | 3-5 working days | 42.9%-50% |
| Port Customs Clearance (including inspection) | 5-8 working days | 3-6 working days | 37.5%-40% |
| Export Tax Refund Receipt | 25-30 working days | 12-15 working days | 52%-60% |
