Pyrethrum powder manufacturers

Pyrethrum powder is derived from the Chrysanthemum cinerariifolium flower. The primary active components are Pyrethrins (Pyrethrin I & II, Cinerin I & II, and Jasmolin I & II). For B2B procurement, you must specify the concentration, typically ranging from 0.5% to 25% extract or pure ground flower head powder. Ensure the supplier provides a Certificate of Analysis (COA) to verify the exact pyrethrin content, as this directly impacts the biological efficacy against pests.

As a natural insecticide, Pyrethrum Powder must comply with strict regulations. For the US market, ensure the supplier is EPA registered or the product meets FIFRA requirements. For the EU, it must align with REACH and the Biocidal Products Regulation (BPR). If the product is intended for organic farming, look for OMRI (Organic Materials Review Institute) listing or ECOCERT certification to guarantee it is free from synthetic synergists like Piperonyl Butoxide (PBO) if a 100% natural profile is required.

Pyrethrins are highly photosensitive and thermolabile, meaning they degrade rapidly when exposed to light, heat, or oxygen. You should require UV-protected, airtight packaging (such as aluminum foil bags or fiber drums with inner liners). Suppliers should provide stability data; ideally, the powder should be stored in a cool, dry place below 25°C to maintain a shelf life of 12 to 24 months.

It is widely used in organic agriculture, public health pest control, and pet care products. In B2B sourcing, clarify if you need raw botanical powder (for incense coils or dusting) or refined extract powder (for wettable powders or aerosol formulations). For agricultural use, check the particle size (mesh count) to ensure compatibility with your application equipment or formulation mixing tanks.

The biggest risk is Customs Seizure due to lack of pesticide registration. Many countries classify Pyrethrum as a regulated pesticide rather than a simple botanical extract. Always verify the HS Code (typically 1302.14 or 3808.91) and ensure your import license matches the chemical's classification. Additionally, watch out for adulteration with synthetic pyrethroids, which are cheaper but illegal in organic applications; always demand Gas Chromatography (GC) testing results.

Utilize Trade Assurance services provided by reputable platforms like Made-in-China.com to protect your payment until delivery. For large orders, hire a third-party inspection agency (like SGS or Intertek) to perform pre-shipment sampling and testing. This ensures the Pyrethrin content matches the sample provided during the negotiation phase.

Pyrethrum Powder is often classified as Environmentally Hazardous Substance (UN 3077, Class 9) for sea freight depending on the concentration. Ensure the supplier provides a valid MSDS (Material Safety Data Sheet) and follows IMDG codes for labeling and stowage. Request 'Away from Heat' stowage on the vessel to prevent thermal degradation during transit through tropical zones.

Focus on long-term volume contracts rather than spot purchases, as pyrethrum flower harvests are seasonal and prices can fluctuate based on crop yields in major regions like East Africa or China. Ask for tiered pricing based on active ingredient percentage rather than just weight. Suppliers on Made-in-China.com are often open to providing free samples (shipping paid by buyer) for lab verification before finalizing bulk contracts.
