China Revises Tariff Code for n-Heptane—Effective from 2025 for International Trade and Customs Declarations
As of 2025, the official HS code for n-Heptane (正庚烷) in China has been updated to 2901109000, replacing previous classifications. This change aligns with China’s ongoing efforts to streamline chemical import/export procedures and improve tariff data accuracy. Exporters, importers, and customs brokers dealing with n-Heptane must take note of this update to ensure smooth customs clearance and compliance in the new year.
HS Code Update 2025: New Customs Classification for n-Heptane
Starting in 2025, China has officially updated the HS code for n-Heptane (正庚烷) to 2901109000. This revision reflects the nation’s broader initiative to standardize customs procedures and enhance trade transparency for chemical products.
n-Heptane, a high-purity hydrocarbon solvent widely used in pharmaceutical synthesis, electronics cleaning, and laboratory research, was previously grouped under broader aliphatic hydrocarbon codes. The new classification under 2901109000 provides greater specificity, reducing ambiguity during customs declarations.
Key Implications for Exporters and Importers:
• Customs Declaration Compliance: All declarations for n-Heptane exports or imports must now reference the updated HS code 2901109000.
• Documentation Updates: Relevant shipping and trade documentation, including invoices, packing lists, and certificates of analysis, should reflect the new code.
• Tariff Adjustment Readiness: Businesses should recheck applicable tariffs or trade agreements tied to this new code to ensure accurate duty calculations.
• System Integration: Companies using ERP or logistics systems must update their product HS code databases accordingly.
This change reinforces the importance of staying current with evolving customs classifications, especially for chemical exporters. Failure to comply with updated HS codes may result in delayed shipments, penalties, or even rejections at ports.
For those exporting high-purity n-Heptane (99%) or technical-grade variants, we recommend verifying with local customs agents or trade authorities to ensure proper implementation.
