Understanding BIR e-Invoicing for Chemicals and Petrochemicals
Chemical and petrochemical companies sell raw materials, solvents, resins, fertilizers, industrial gases, lubricants and fuels to manufacturers, farms, construction firms, utilities and retailers. Products may ship by tanker, ISO container, drum, bag or small retail pack, and pricing often moves with raw material costs. Each shipment can involve safety documents, delivery records and different tax treatments, depending on the product and the transaction.
