In foreign trade, 'Lock' (锁扣) typically refers to a mechanical fastening device used on containers, packing cases, doors/windows, or industrial equipment. Its core function is to ensure the safety and sealing of goods during transportation. Usage scenarios include: container door locks, air case locks, heavy equipment packaging locks, etc. Notes: 1. Specify the material (e.g., stainless steel, zinc alloy), dimensions, load-bearing grade, and surface treatment (e.g., galvanized, sprayed), as these directly affect price and applicability; 2. If used for export containers, it must comply with ISO standards or destination country customs requirements (e.g., US C-TPAT anti-terrorism locks); 3. Distinguish from 'Seal': locks are reusable, while seals are mostly one-time use and often carry a unique number for customs inspection; 4. Distinguish from 'Latch': locks usually have a key or combination lock core, while latches rely solely on mechanical snap fixation. When quoting, specify whether a lock core is included, the number of keys, and packaging method.
📝 Examples
1. Please quote FOB Shanghai for 5,000 stainless steel container door locks, requiring a load capacity of 2,000 kg, galvanized surface, and a third-party inspection report. (Note: Specify specifications, trade terms, and certification requirements to facilitate accurate supplier quoting.) 2. The batch of locks we received does not match the sample; the lock core cannot be opened normally. Please arrange replacement immediately and bear the related freight costs. (Note: Claim communication for quality non-conformity, emphasizing lock functional defects and liability.)
