Specification

Specification is a core term in foreign trade contracts and product descriptions, referring to the detailed explanation of specific requirements for a commodity such as technical parameters, dimensions, materials, performance, and packaging. It usually appears in purchase orders, proforma invoices, sales contracts, letters of credit, and product catalogs, and is the basis for both buyer and seller to confirm product standards, inspection criteria, and delivery conditions. Usage scenarios include: customers requesting specification sheets during inquiries, clarifying specification differences during quotation, confirming specifications before production to avoid disputes, and providing specification data during customs declaration and inspection. Notes: Specifications must be specific and quantifiable, avoiding vague expressions (such as 'high quality'); specification standards may differ across markets (such as voltage, plugs, environmental requirements), and must be confirmed in advance; specification changes require written confirmation and may affect price and delivery time. Difference from 'Quality': quality focuses on overall grade of superiority or inferiority, while specification focuses on specific technical indicators; difference from 'Model': model is a simplified code for specifications, while specification is the detailed expansion of the model. Difference from 'Description': description may include specifications but is broader and may contain subjective descriptions.
