Singapore is a signatory to the Chemical Weapons Convention (CWC), which regulates the trade of certain chemicals to prevent their misuse. Under Singapore Customs regulations, the import of chemicals classified as NA(CWC) Controlled Items must follow strict control measures including obtaining the proper CWC licence and import permit.
Businesses dealing with these regulated chemicals must ensure that all import declarations are accurate, complete, and compliant with Customs requirements.
What are NA(CWC) Controlled Items?
NA(CWC) refers to chemicals and related substances listed under the Chemical Weapons Convention (CWC) schedules. These include Schedule 1, 2, and 3 chemicals, which vary in sensitivity and control level.
Singapore Customs enforces these controls to ensure that chemicals are imported strictly for legitimate industrial, medical, or research purposes.
Import Requirements for NA(CWC) Controlled Items
Before importing such chemicals into Singapore, importers must:
- Hold a valid CWC licence issued by the National Authority.
- Apply for an import permit via TradeNet — with all necessary details and supporting documentation.
- Provide advance notification for Schedule 1 chemicals (before and after transfer).
- Comply with restrictions when importing from non-CWC Member States (for example, mixture concentration limits for Schedule 2 chemicals).
Permit applications are generally processed within two working days if all information is correctly submitted.
What Must Be Declared in the Permit Application
When submitting the import permit for NA(CWC) items, key details must be accurately declared, including:
- Customs Procedure Code (CWC)
- CWC Licence Number
- HS Code and Product Description
- CA or SC Product Code (as indicated in the licence)
- Purity or Composition of the chemical
- Quantity and Unit of Measure
Incomplete or incorrect declarations can result in permit rejection, shipment delays, or enforcement actions.
