Strategic Advantage of Junyuan Petroleum Group

Through global production and mature technology, Junyuan Petroleum Group provides high-purity, eco-friendly, and stable supply of n-Heptane, meeting the strict standards of European clients. With full REACH certification since 2025, the n-Heptane market in Europe is poised for comprehensive growth.

Abstract:
n-Heptane (CAS 142-82-5; EC 205-563-8) is a registered substance under the European Union’s REACH regulation, enabling its safe and compliant use across diverse industries. As a mono-constituent substance of petroleum origin, n-Heptane is registered for tonnage bands exceeding 1,000 tonnes per year, ensuring wide availability for European buyers. The REACH registration dossier highlights its extensive applications, including as a solvent in manufacturing, a fuel additive, a component in coatings and adhesives, and in laboratory processes. Businesses sourcing n-Heptane in the EU should request REACH certificates, Safety Data Sheets (SDS), and confirmation of tonnage coverage from suppliers to guarantee regulatory compliance. For downstream users, verifying that specific applications are covered in the supplier’s dossier is crucial, while importers must ensure valid registration via their EU-based entity or Only Representative. With its robust regulatory framework and versatile uses, n-Heptane is positioned as a reliable, compliant, and high-value solvent and process material in the European market.

n-Heptane and REACH Registration in the EU

n-Heptane has been successfully registered under the EU’s REACH regulation (Registration, Evaluation, Authorisation and Restriction of Chemicals). The registration process ensures that the substance complies with stringent European standards for safety, environmental impact, and responsible use.

• Identifiers:
  • CAS Number: 142-82-5
  • EC Number: 205-563-8
  • Typical Registration Number Format: 01-2119457603-38-xxxx
• Substance Type:
  n-Heptane is registered as a mono-constituent substance, most commonly of petroleum origin.
• Tonnage Band:
  Registrations cover >1,000 tonnes per year, reflecting its broad industrial demand.

Industrial Applications of n-Heptane

The versatility of n-Heptane makes it an essential material across multiple European industries. Key applications include:

• Solvent in manufacturing processes – widely used in adhesives, coatings, and extraction processes.
• Fuel and fuel additives – supporting clean combustion and blending.
• Cleaning agents – valued for its efficiency in dissolving oils and greases.
• Laboratory applications – as a reference solvent and calibration standard.
• Formulations – incorporated into paints, coatings, and industrial adhesives.

Compliance Documentation for Buyers

To ensure smooth operations and full compliance, buyers in the EU should request the following documents from suppliers:

1. REACH Certificate – official proof that the product is registered under REACH.
2. Safety Data Sheet (SDS) – including the REACH registration number and hazard/safety guidance.
3. Confirmation of Tonnage Coverage – assurance that the supplier’s registration covers the required quantity and intended use.

Obligations for Buyers in the EU

• Downstream Users:
  Businesses that use n-Heptane in production must confirm that their applications are included in the supplier’s registration dossier. The SDS will provide this detail.
• Importers:
  If n-Heptane is imported from outside the EU, the responsibility for REACH registration lies with the importer. Alternatively, the non-EU manufacturer can appoint an “Only Representative” to manage registration on their behalf. In both cases, importers should obtain the valid REACH registration number.

Conclusion

With full REACH registration, n-Heptane is a reliable and compliant material for European industries. Its wide-ranging applications, regulatory approval, and high-volume availability position it as a critical solvent and process chemical. By sourcing from trusted suppliers and ensuring the proper documentation, buyers can secure both regulatory compliance and uninterrupted supply.

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 Labour Day holidays vary across countries, timely coordination in logistics becomes essential. For global buyers of hydrocarbons like Pentane, Hexane, Heptane, and sulfiding agents, early planning ensures supply chain continuity during the early May slowdown.

With the global Labour Day (May Day) holidays approaching, it’s crucial for international buyers of chemical raw materials to prepare ahead—especially when sourcing from across regions with varying public holiday schedules.

Our product portfolio covers a wide range of high-purity hydrocarbons, including n-Pentane, Isopentane, Cyclopentane, n-Hexane, n-Heptane, and various sulfiding agents. These materials serve industries from polyurethane insulation, refrigeration, and adhesives to pharmaceuticals, refining, and electronics.

Key Holiday Timelines to Note:

• Russia: May 1–3, with many extending holidays until May 9 (Victory Day)

• Japan: Golden Week, typically May 1–7, with some businesses closed for up to 11 days

• France: May 1 only, strict labor laws prohibit most business activities

• Australia: Varies by state, with Queensland and Northern Territory observing May 6

• UK, Egypt, Pakistan, South Africa, Thailand, and others: May 1 as a national holiday

No May 1 Holidays:

Markets such as South Korea, Israel, the United States, Canada, and the Netherlands operate normally during early May but observe labor-related holidays at other times.

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.
