Import Declaration Warning for Chemical Products: Three Compliance Traps and On-the-Ground Operations That 90% of People Overlook
or complex compliance issues.
clearance and fund security.

Can obtaining the "Dangerous Chemicals Business License" and the "Import License" ensure smooth customs clearance?Last year,out of the 12 Class I chemical import cases I handled,seven failed due to "non-compliance with regulatory details without approval documents" — either the MSDS version didn’t match and the goods were detained for three days,or label translation errors led to returns,resulting in a loss of 80,000 yuan in demurrage fees.What’s more troublesome is that once the customs add the company to the "Key Supervision List",the subsequent three months of customs declarations will be subject to stricter inspections.
The "invisible threshold" for declaring a certain category of chemical products: the real challenge lies not in obtaining the necessary approvals,but in failing to establish a complete compliance system
A category of chemical products (such as flammable liquids and corrosive substances)The core issue is not whether there is an approval document,but rather ensuring full-chain compliance beyond the approval process.According to the "Regulations on the Safety Management of Hazardous Chemicals" (State Council Decree No.591) and the General Administration of Customs Announcement No.129 of 2020,the import of Class I chemical products must meet three requirements: "document compliance,label compliance,and property compliance".Any failure in any of these three aspects will result in a failed customs clearance.
| Common Compliance Misconceptions | Correct operation requirements | Non-compliance consequences |
|---|---|---|
| It’s fine to use the Chinese version of the MSDS provided by the factory | It is required to provide a Chinese-English version that complies with GB/T 16483-2008,and it must be signed and stamped by the manufacturer | For the inspection of the goods,it is necessary to provide an MSDS that meets the requirements again,which will result in a delay of 3-5 days |
| For tag translation,just use machine translation directly | It must comply with the "Regulations on the Preparation of Labels for Hazardous Chemicals" (GB 15258-2019),and the key elements (hazard class,precautionary statements,UN number) must be accurate. | The mislabeling resulted in the return of the goods,which increased the cost by 20% to 30%. |
| We will conduct a hazardous goods characteristic test after the goods arrive | It is necessary to obtain the Hazardous Property Classification and Identification Report from a third-party testing institution (such as SGS or CTI) before customs declaration. | I can’t declare the goods,and the cargo is stuck in the port.The daily demurrage fee is 500-1000 yuan per container. |

Secrets Old Freight Forwarders Won’t Tell: The "Tax + Legal" Double Insurance for Class 1 Chemical Customs Declaration
1.Tax Traps: Some Class I chemical products are classified as "consumption taxable products" (such as gasoline,diesel,and solvent oil),and when declaring them,you need to select the corresponding consumption tax code in the "Product Code" (e.g.2710121000,gasoline).If you fail to select the correct code,you will be required to pay back taxes and penalties (5% per day) at a later stage.
2.Legal Skills: When signing contracts with foreign suppliers,it is necessary to add a "Seller’s Guarantee Clause" - "The seller guarantees that the MSDS and labels provided comply with Chinese GB standards.If the customs clearance fails due to errors in the MSDS or labels,the seller shall bear the costs of return shipment and demurrage fees." Last year,one of my clients successfully claimed 120,000 yuan in return shipment losses from the supplier based on this clause.
