Public Health Insecticide Active Ingredients from China
WECON is a Hong Kong trading company exporting pesticide technical material and public-health insecticide actives from Chinese factories. We supply mosquito coil, aerosol, liquid vaporiser, repellent and veterinary ectoparasiticide manufacturers — including buyers specifically looking for a qualified second source in China.
Who we supply
Built for household and public-health manufacturers
Mosquito coil & mat producers
Tetramethrin, permethrin and allethrin-class actives in purities and colour grades that survive coil moulding and drying without odour issues.
Aerosol & LEV manufacturers
Knock-down plus residual pyrethroid combinations for aerosols, liquid electric vaporisers and pump sprays, with PBO synergist compatibility data.
Veterinary ectoparasiticide makers
Permethrin and cypermethrin technical for spot-on, dip and collar products, with isomer ratio matched to your registered specification.
Vector-control formulators
Deltamethrin and lambda-cyhalothrin TC for IRS, net treatment and space-spray programmes tendered by health ministries and NGOs.
Second-source programme
Single-supplier dependency is the biggest supply risk in this category. Our qualification path is designed to be audit-friendly and to keep your registered specification untouched.
- 1Share your current specification and impurity limits (NDA available)
- 2We match a factory and ship a free analytical sample with COA
- 3You run HPLC/GC-MS and formulation trials against your standard
- 425–200 kg trial batch, then parallel commercial supply

Frequently asked questions
Which public health insecticide actives do you supply?
Permethrin (25/75 and 40/60 cis/trans), tetramethrin, cypermethrin, beta-cypermethrin, deltamethrin and lambda-cyhalothrin technical material, sourced directly from Chinese manufacturers and shipped with lot-level COA, SDS, specification and impurity profile.
Can WECON act as a second source next to our current Chinese supplier?
Yes — second-source qualification is our core service. We match your existing specification (purity, isomer ratio, colour, odour, impurity limits), ship a qualification sample, then run parallel small-batch supply before you move volume across.
Do you supply actives for mosquito coils and liquid electric vaporisers?
Yes. Tetramethrin, permethrin and d-allethrin-class actives for coil, mat and liquid electric vaporiser (LEV) production, in purities and colour grades suited to household insecticide manufacturing.
What documentation comes with each shipment?
Specification sheet, batch COA, GHS-compliant SDS, impurity profile and, for registration files, 5-batch analysis and toxicology summaries. Dangerous-goods classification and UN-certified packing are handled in-house.
Can we order samples or small trial quantities first?
Analytical samples of 100 g to 1 kg are free of charge. Trial quantities of 25–200 kg ship at FOB cost and are credited against the first commercial order.
