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.

As of April 28, 2025, the domestic price for 99% purity n-Heptane in China remains stable at RMB 15,900 per metric ton, approximately USD 2,170 per metric ton based on the current exchange rate (1 USD ≈ 7.327 RMB).

Following a sharp price adjustment around mid-April, the market has entered a period of stability, with no fluctuations recorded over the past two weeks. For global procurement teams, this price consistency provides a more predictable environment after recent volatility.

The stable trend is largely supported by balanced domestic supply and steady demand from key downstream sectors such as pharmaceuticals, adhesives, and industrial solvents. Buyers worldwide are advised to continue monitoring market conditions closely, as potential shifts in feedstock availability or production rates could impact export offers in the coming months.

With China being a major supplier of high-purity n-Heptane, the current stability offers an opportunity for strategic procurement planning and inventory management for Q2 2025.

n-Heptane, 99% Purity, Global Procurement, Market Price, Price Stability, China Exports, Solvent Market, April 2025, USD Price, RMB Price

This analysis focuses on the price trend of 99% pure n-Heptane in the Central China region from April 14 to April 25, 2025. The data reveals a significant price change within this period.

On April 14, the price of 99% n-Heptane was relatively high in the Central China market. However, the price began to decline soon after, marking a noticeable and continuous downward trend. By April 25, the price stabilized at RMB 15,200/ton (~USD 2,080/ton), with no further changes on that day, showing a price fluctuation of 0.00%.

For purchasers, this price trend highlights several key points to consider. First, whether this downward trend is temporary or indicative of a long-term market shift is crucial. If the decline is only a short-term adjustment, prices may stabilize or even increase later. In this case, excessive stockpiling at the current low prices could lead to higher costs if prices rebound. On the other hand, if the price drop is due to fundamental industry changes, such as increased raw material supply or heightened market competition, buyers could take advantage of this opportunity to increase their purchasing volume within reasonable limits to lower their average procurement costs.

The supply side dynamics are also essential for purchasers to monitor closely. If new n-Heptane production facilities are launched or existing companies expand production, market supply could significantly increase. If demand remains stable or grows slowly, prices may continue to face downward pressure. Conversely, if production plants shut down or face maintenance issues, leading to reduced supply, prices could stabilize or rebound. Therefore, purchasers should stay informed about supply-side changes through communication with suppliers and industry news.

Additionally, the availability of substitutes should not be overlooked. In the chemical raw materials market, multiple alternatives with similar functions often exist. If the price of n-Heptane continues to fall, its relative cost-effectiveness may change. If comparable substitutes with better pricing emerge, purchasers may need to reassess their procurement strategies or even consider adjusting product formulas to incorporate these substitutes and reduce costs.

Industry policies and the development of upstream and downstream industries also influence n-Heptane prices. For instance, stricter environmental regulations could limit the production of n-Heptane, impacting both supply and prices. Similarly, changes in the demand from n-Heptane’s downstream industries will directly reflect on its price. Purchasers should stay attuned to industry policies and the trends in upstream and downstream industries to make more informed purchasing decisions in a complex market environment.

In summary, the price of 99% n-Heptane in Central China decreased in April 2025 and stabilized by the end of the month. In future procurement activities, buyers should carefully consider factors such as the su
