Chemical categories

Isocyanates, polyols, prepolymers and curing agents for polyurethane foams, elastomers, coatings and adhesives. The flagship category of the platform: every grade listed here is matched against the CAS-verified product records buyers compare before requesting a quotation. Sits at the head of the taxonomy because flexible and rigid PU chemistry is where SupplierAssess has the deepest supplier coverage today.

Pharmaceutical intermediates, active ingredients, excipients and biological chemicals sourced from producers that publish the documentation importers need — DMF support, GMP statements and lot-level COA. Covers human and veterinary drug supply chains, from impurity standards used in analytical work to bulk fermentation-derived actives. Compare declared capacity, regulatory filings and certification sets before requesting a quotation.

Pesticide actives, intermediates, adjuvants and fertilizers for crop protection and crop nutrition. Buyers compare technical content, formulation type, impurity profiles and registration support for the destination market. This category aggregates producers of herbicides, insecticides, fungicides and plant growth regulators together with the upstream intermediates and inert ingredients behind them.

Raw materials and finished systems for architectural coatings, industrial paints, printing inks and their auxiliaries. Includes pigments, resins, solvents, additives, fillers and the ink chemistries used in packaging and publication printing. Buyers screen for tinting strength, dispersibility, VOC classification, light fastness and regulatory approval for food-contact or heavy-duty service.

Polymers, resins, metal and ceramic materials, nanomaterials and advanced materials used in plastics, composites, electronics and energy devices. The category spans commodity polymers and specialist substrates — from PVC and engineering resins to battery separators and printed-electronics materials. Buyers compare grade, molecular weight, filler loading and thermal performance.

Inorganic and organic pigments, solvent and disperse dyes and the intermediates behind them. Applications run from coatings, plastics and construction materials to textile dyeing, leather finishing and high-purity electronic colourants. Key comparison parameters are colour strength, tinting strength, heat stability, light fastness and heavy-metal limits such as APEO and free formaldehyde.

Aroma chemicals, essential oils and the intermediates and carriers used in flavour and fragrance compounding. Serves food and beverage, personal care, household and industrial odour-management applications. Buyers compare odour profile, purity by GC, optical rotation, allergen declaration and IFRA documentation for the intended use level.

Food-grade additives, acidulants, polyols, preservatives, thickeners and animal nutrition ingredients manufactured under FSSC 22000, ISO 22000, HALAL and KOSHER schemes. Buyers compare assay, mesh size, heavy-metal limits and the document set required for import clearance. This category lists fermentation and synthesis producers exporting to food, beverage and feed manufacturers.

Plant, animal and fungal extracts, botanical drug materials, natural colorants and natural toxins. Serves nutraceuticals, cosmetics, traditional medicine and analytical reference standards. Buyers assess marker-compound content, extraction solvent, extract ratio, pesticide residue and heavy-metal limits, plus the identification data needed for pharmacopoeial work.

Industrial catalysts and the processing auxiliaries — antioxidants, stabilisers, lubricants, flame retardants, accelerators and mould-release agents — that determine processing window and service life. Selection depends on polymer or feedstock type, operating temperature and regulatory approval. This category lists producers serving compounders, masterbatch makers and tyre manufacturers.

High-volume inorganic and organic building blocks: chlor-alkali products, industrial acids and bases, mineral fillers, oleochemicals, petrochemicals and bulk solvents. These feed almost every downstream chemistry, so buyers compare assay, impurity limits, packaging format and supply reliability more than differentiation. Includes Chinese producers with published capacity and export documentation.

Cosmetic ingredients, surfactants, detergents, oral care chemicals and household pest-control actives. Covers the raw materials behind personal care formulations — emulsifiers, humectants, thickeners, UV filters and conditioning agents — alongside cleaning and hygiene chemistry. Buyers screen for INCI name, grade, preservative system compatibility and cosmetic regulatory compliance.

Photonic and optical materials, liquid crystals, OLED and OFET materials, semiconductor-grade monomers, substrate and electrode materials and battery chemicals. Purity is the decisive parameter: trace-metal content, particle count and moisture are compared at ppb level. This category serves display, semiconductor, printed-electronics and energy-storage supply chains.

Categories that sit outside the main chemical families: adhesives, water treatment chemicals, forest products chemicals, leather and paper chemicals, and laboratory reagents. These are the consumables behind bonding, effluent control, pulping, tanning and analytical work. Buyers compare activity, dosage, compatibility with the substrate or process and certification for the target industry.
