Camphor tablet

When sourcing camphor tablets, the most critical factor is the purity level, typically ranging from 96% to 99%. For industrial use (mothproofing, fragrance), Technical Grade is sufficient. However, for pharmaceutical or topical applications, you must ensure the product meets USP (United States Pharmacopeia) or BP (British Pharmacopeia) standards. Always verify the melting point (174°C - 179°C) and non-volatile residue (less than 0.05%) to ensure the product is not adulterated with cheaper fillers like naphthalene.

Camphor is highly volatile and sublimes at room temperature. To prevent weight loss and potency reduction, tablets should be individually wrapped in cellophane or high-density polyethylene (HDPE) and then packed in airtight tin containers or multi-layer laminated pouches. Ensure the supplier provides UV-protected packaging, as exposure to light can cause yellowing and degradation of the camphor's chemical structure.

Because camphor is a chemical substance, you must request a Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch. For the US market, compliance with EPA (Environmental Protection Agency) regulations for pesticides/repellents is necessary. For the EU, ensure the supplier adheres to REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals). If the tablets are intended for religious or medicinal use, check for ISO 9001:2015 manufacturing standards to ensure consistent quality.

Synthetic camphor (derived from turpentine) is the most common for B2B bulk sourcing due to its cost-effectiveness in pest control, deodorization, and industrial manufacturing. Natural camphor (derived from the Cinnamomum camphora tree) is preferred for high-end aromatherapy and traditional medicine, though it carries a significantly higher price point. Buyers should clarify the source material to match their specific market segment's expectations for scent profile and skin sensitivity.

Camphor is classified as a Class 4.1 Flammable Solid (UN 2717). It is imperative to use a freight forwarder experienced in Hazardous Materials (HazMat). You must ensure the cargo is stored in a cool, well-ventilated area away from heat sources and oxidizers. Failure to declare camphor as dangerous goods can lead to heavy fines, shipment seizure, or vessel fires.

Focus on volume-based pricing tiers; camphor production is highly sensitive to raw material (alpha-pinene) costs, so long-term supply contracts can hedge against price volatility. Request pre-shipment samples for lab testing and insist on Trade Assurance or similar secure payment methods to protect your funds until the third-party inspection (like SGS or Intertek) confirms the purity and weight.

Always verify the supplier's Business License and Export Permit specifically for chemical products. Use the Verified Supplier filters on Made-in-China.com to identify manufacturers with audited production lines. Avoid suppliers who refuse to provide a COA (Certificate of Analysis) or those whose prices are significantly lower than the market average, as this often indicates naphthalene contamination, which is toxic and restricted in many countries.
