Camphor

When sourcing camphor, the primary focus should be on purity levels, which typically range from 96% to 99% or higher. For pharmaceutical applications, ensure the product meets USP (United States Pharmacopeia) or BP (British Pharmacopeia) standards. Key physical properties to verify include the melting point (typically 174°C to 179°C) and optical rotation, which distinguishes between natural (D-camphor) and synthetic (DL-camphor) varieties. Additionally, check for residual solvent levels and heavy metal content to ensure safety in end-use applications.

Natural Camphor is extracted from the wood of the Cinnamomum camphora tree and is preferred in high-end aromatherapy and traditional medicine due to its specific aromatic profile. Synthetic Camphor, derived from turpentine oil (alpha-pinene), is the industry standard for mothballs, plasticizers, and topical ointments due to its cost-effectiveness and stable supply. Buyers should request a Certificate of Analysis (COA) to confirm the origin and chemical composition before finalizing a bulk purchase.

Camphor is classified as a flammable solid (Class 4.1 hazardous material) under international shipping regulations. Suppliers must provide a Material Safety Data Sheet (MSDS) and comply with GHS (Globally Harmonized System) labeling. For entry into the EU, REACH registration is essential. If the camphor is intended for medical or cosmetic use, the manufacturer should hold GMP (Good Manufacturing Practice) or ISO 22716 certifications to guarantee hygiene and quality control.

Camphor is highly versatile, serving the pharmaceutical industry for topical analgesics and decongestants, the chemical industry as a plasticizer for celluloid, and the consumer goods sector for pest repellents and incense. In the fragrance industry, it is used as a base note for its cooling sensation. Understanding the specific application helps in choosing the right particle size (powder, tablets, or slabs) and packaging type to prevent sublimation during storage.

The biggest risk is product sublimation (evaporation) and quality degradation during long-term transit. To mitigate this, ensure the supplier uses airtight, moisture-proof packaging such as PE-lined drums or vacuum-sealed bags. For transaction security, use Trade Assurance services on Made-in-China.com and consider third-party inspections (like SGS or Intertek) to verify purity and weight at the loading port before final payment.

Since camphor is a flammable solid (UN 2717), it requires specialized dangerous goods (DG) packaging and labeling. Buyers should negotiate Incoterms like FOB or CIF carefully, ensuring the freight forwarder is experienced in handling Class 4.1 cargo. It is vital to avoid high-temperature storage areas on vessels to prevent the risk of fire or excessive loss through evaporation.

Camphor prices are often tied to the cost of raw materials like turpentine oil. To secure better rates, consider long-term supply contracts or purchasing during the off-peak season. Bulk orders exceeding 5-10 metric tons usually trigger significant discounts. Always ask for tiered pricing based on volume and inquire if the supplier can offer customized tablet sizes to reduce your local processing costs.
