Wholesale chemical and raw material categories include: industrial solvents (alcohols, ketones, esters, aromatic, glycol ethers); polymers and plastic resins (commodity PE/PP/PVC/PET and engineering ABS/PC/PA/PEEK); surfactants (anionic, cationic, nonionic, amphoteric, biosurfactant); adhesives and sealants (epoxy, polyurethane, silicone, hot-melt); pigments and dyes (organic/inorganic pigments, reactive/disperse dyes); specialty chemicals (food additives, flavours, fragrances, pharma excipients, personal care ingredients, electronic chemicals); fertilizers and agrochemicals (NPK, urea, potash, herbicides, insecticides, fungicides); industrial lubricants (gear oils, hydraulic fluids, cutting fluids, greases); and metal powders (aluminium, titanium, copper, iron, stainless steel, nickel alloy).

REACH (Regulation EC 1907/2006) requires chemical manufacturers and importers in the EU to register substances above 1 tonne/year with ECHA (European Chemicals Agency). Substances of Very High Concern (SVHC) are placed on the Candidate List and may require authorisation for continued use. Non-EU suppliers must appoint an Only Representative (OR) for REACH registration. Buyers importing chemicals into the EU should confirm REACH registration numbers (provided on the Safety Data Sheet under Section 1) and check the SVHC Candidate List before procurement. As of 2026, over 240 SVHCs are listed.

The Globally Harmonised System (GHS) classifies chemicals by hazard (physical, health, environmental) using standardised pictograms, hazard statements (H-codes), and precautionary statements (P-codes). In the EU, GHS is implemented as CLP (Classification, Labelling and Packaging — Regulation EC 1272/2008). Safety Data Sheets (SDS) in 16-section format are mandatory for all hazardous chemicals and must be provided in the buyer's official language. Always request an up-to-date SDS (revision date within 3 years) and confirm it complies with REACH Annex II.

Chemicals are classified under the UN Model Regulations into 9 classes: Class 1 (explosives), Class 2 (gases), Class 3 (flammable liquids — most solvents), Class 4 (flammable solids — some metal powders), Class 5 (oxidisers — some fertilizers), Class 6 (toxic/infectious), Class 8 (corrosives), Class 9 (miscellaneous). Transport regulations: ADR (road in EU/UNECE countries), IMDG Code (sea), IATA DGR (air). Each substance requires a UN number, proper shipping name, packing group (I/II/III), and emergency response information. Bulk chemicals in IBCs or ISO tanks require additional documentation.

Food-grade chemicals (emulsifiers, flavours, colours, preservatives, processing aids) used in halal or kosher food production must be certified accordingly. Halal certification applies to ingredients of animal origin (gelatine, glycerol, enzymes) and ensures no alcohol-derived processing aids. KOSHER certification requires rabbinic supervision and segregation from non-kosher processes. Major certification bodies: IFANCA, MUI (Indonesia), JAKIM (Malaysia) for halal; OU, OK Kosher, Star-K for kosher. Buyers should request current certificates with expiry dates and applicable product scope.

Chemical MOQs vary by product state and packaging: bulk liquids via ISO tanker from 20 tonnes; IBC (1,000-litre tote) from 1 unit; drum (200-litre) from 5 drums (1 pallet); specialty chemicals in pails (20–25 kg) from 10 units. Solid chemicals: big bags (500–1,000 kg) from 1 unit; 25 kg bags from 40 bags (1 pallet); metal powders from 5 kg for specialty grades. Commodity polymers (PE/PP pellets): minimum 1 FCL (20 tonnes). Specialty chemicals (pharma excipients, electronic chemicals): from 25–100 kg with sample quantities of 100 g–1 kg available.
