Lumping
The manual unloading of freight from a trailer or container, typically performed by a specialist labour crew at a distribution facility.
Full Definition
Lumping refers to the physical labour of unloading goods from a truck trailer or shipping container, often performed by contracted workers (lumpers) rather than the driver or warehouse's regular staff. Lumper fees are a common line item in freight invoices and can be a source of billing disputes. Editors working on logistics invoices or carrier agreements should be familiar with the term and understand that it refers specifically to the labour cost of unloading, not loading. 'Lumping' is a gerund form; 'lumper' (the worker performing the task) is the related agent noun.
Usage
Usage note: Colloquial but widely used in North American trucking and warehousing. 'Lumper fee' is the standard billing term. Clarify in documents intended for international audiences.
