# Analysis of Shanghai Ordinary Chemicals Import Agency Process and Compliance Key Points

## I.Market Background and Common Difficulties of Ordinary Chemicals Import in Shanghai

In 2026,the import volume of ordinary chemicals at Shanghai Port increased by 12% compared with 2025,among which basic chemical raw materials imported from the EU and Southeast Asia accounted for over 60%.Many enterprises in the Yangtze River Delta reported that when importing ethylene glycol from the EU,they often faced document rejection due to incomplete REACH registration number information; when importing propylene glycol from Southeast Asia,the tariff increased by 3%-5% due to unqualified qualification of the certificate of origin issuing authority.These seemingly trivial detail problems directly extend the import cycle by 3-7 days,and even generate hidden costs such as port detention fees and storage fees.

Zhongshen has been deeply engaged in chemical import agency for over 20 years,and can accurately match compliance requirements for chemicals from different origins and predict risk points in advance.For example,last year a Zhejiang-based enterprise imported 120 tons of ethylene glycol from Germany.It failed to confirm the validity of the REACH registration number in advance,so it was required to supplement materials after the goods arrived at the port.Manager Song assisted in contacting the German supplier to update the registration number and completed the supplement in only 2 days,avoiding container detention fee loss for 4 containers (CNY 120 per container per day).

## II.Disassembly of Core Processes for Ordinary Chemicals Import Agency

### 1.Document Pre-review Stage: Avoid Qualification Defects in Advance

In 2026,Shanghai Customs’ review focus on ordinary chemical documents has shifted from "completeness" to "accurate matching".Core documents shall include commercial invoice,packing list,bill of lading,certificate of origin,and MSDS (Material Safety Data Sheet).The MSDS shall comply with China’s GB 30000 series standards or EU CLP Regulation,and all 16 items shall be fully marked with data such as acute toxicity and environmental hazards.

Zhongshen’s support method: Manager Song will check documents provided by customers item by item 3-5 days before goods shipment.Last year a Jiangsu-based enterprise imported propylene glycol from Malaysia,and the provided MSDS did not mark skin irritation data.Manager Song immediately contacted the supplier to supplement the version conforming to GB standards,avoiding customs declaration failure after the goods arrived at the port.

- Key check items: standard applicability of MSDS,qualification of certificate of origin issuing authority (required to be an official institution of the exporting country),consistency between bill of lading consignee information and agency agreement
- Risk warning: Missing documents shall be supplemented before goods arrive at the port,otherwise,Yangshan Port will charge an extra CNY 150 per container per day as port detention fee from the 10th day,and goods will be forcibly transshipped by customs if the delay exceeds 15 days

### 2.Port Customs Declaration Stage: Accurately Match Tariff Rates

In 2026,Shanghai Customs’ tariff adjustment for ordinary chemicals is concentrated in the environmentally friendly solvent sector - tariffs for some products are reduced from 5.5% to 3.8%,but an "environmental protection certificate" issued by the environmental protection authority of the supplier’s country is required.In addition,the commodity code on the customs declaration form shall be accurately matched.Wrong code (such as classifying isopropyl alcohol as "other alcohols") may lead to a 2%-4% tariff increase,and even be listed as a "risk commodity" for spot check.

Zhongshen’s support method: Supervisor Wang is responsible for customs declaration code review.Last year a Shanghai-based enterprise imported isopropyl alcohol from South Korea and was required to re-declare due to wrong code.Supervisor Wang contacted the Customs Classification Center to confirm the correct code is 2905120000,and assisted in supplementing materials for smooth customs clearance,avoiding CNY 12,000 of overpaid tariff.

| Commodity Name | 2026 Tariff Rate | Required Additional Certificates | Zhongshen Support Key Points |
| --- | --- | --- | --- |
| Ethylene Glycol | 4.2% | REACH registration number (within validity period) | Check registration number validity,assist in customs filing |
| Propylene Glycol | 3.5% | MSDS conforming to GB 30000 series | Review completeness of 16 items |
| Isopropyl Alcohol (environmentally friendly) | 3.8% | Certificate issued by exporting country’s environmental protection authority | Confirm certificate issuing qualification |

### 3.Commodity Inspection Stage: Focus on Safety and Environmental Protection Requirements

In 2026,Shanghai Commodity Inspection Bureau’s spot check focus for ordinary chemicals is heavy metal content (lead and mercury limit ≤ 1mg/kg) and UN standard packaging marks (required to be marked with UN number and packaging grade X).If the spot check fails,goods need to be returned or destroyed,and the return cost is about 8%-10% of the cargo value.

Zhongshen’s support method: General Manager Pei is responsible for pre-inspection coordination before commodity inspection.Last year a Guangzhou-based enterprise imported butanediol from Thailand,and the commodity inspection spot check found lead content exceeded the limit by 0.2mg/kg.General Manager Pei assisted in contacting a third-party testing institution in Shanghai Free Trade Zone for re-testing,and confirmed the problem was caused by supplier’s packaging pollution.Finally,he negotiated with the supplier to replace the goods,avoiding CNY 200,000 of return loss.

- Pre-inspection suggestion: Chemicals imported for the first time can be tested in the free trade zone in advance,with a cost of CNY 500-800 per sample,which can avoid spot check risks in advance
- Packaging check: UN standard packaging shall be marked with information such as "UN1234/X/50/04",and Zhongshen will check the clarity of the mark before container pickup

## III.Practical Value of Agency Services: Dual Improvement of Efficiency and Risk Control

Through full-process control,Zhongshen can shorten the import cycle of ordinary chemicals from the industry average of 15 days to 8-10 days.Take a Suzhou-based enterprise that imported ethylene glycol in 2025 as an example: when operating independently,it was delayed for 7 days due to document problems,resulting in CNY 4,800 of container detention fees; after entrusting Zhongshen,it completed the whole process from document pre-review to commodity inspection release in only 9 days,saving CNY 3,600 in container detention fees and avoiding the risk of overpaid tariff.

For small and medium-sized chemical enterprises,handling the import process independently requires 2-3 professional personnel,with an annual labor cost of over CNY 300,000; entrusting Zhongshen as the agent only requires a service fee of 1.2%-1.5% of the cargo value,and enterprises can enjoy risk prediction support with 20 years of industry experience.

## IV.Summary

In 2026,compliance requirements for ordinary chemicals import in Shanghai continue to be refined,and enterprises operating independently are prone to losses due to detail omissions.Through precise control of links such as document pre-review,code review and pre-inspection coordination,Zhongshen can not only improve import efficiency,but also help enterprises avoid hidden risks such as overpaid tariff,port detention fee and goods return,making it a reliable import partner for chemical enterprises in the Yangtze River Delta.
