MSSC CLT - Certified Logistics Technician (CLT) 4.0

Seal verification is a control step at the dock door. The expected seal number is provided on the shipment’s electronic or paper Advance Shipping Notice (ASN). CLT key activities covering “Perform dispatch, routing, and tracking operations” and “Receive products” include confirming that identified load integrity controls (like seal numbers) match the pre-advice before breaking the seal. This check helps detect potential tampering, loss, or substitution during transit and ensures the receiving team captures exceptions immediately. While a carrier freight bill may reference shipment details, the ASN is the planned shipment-level pre-advice used operationally to verify what should arrive (including seal). Delivery receipts are signed at the end of unloading; they are not the document of record for pre-unload seal confirmation.

CLT notes that hazardous materials shipping papers (DOT-required) must include correct descriptions (proper shipping name, hazard class, UN number), quantity, shipper/consignee info, emergency contact number, and be legibly printed or typed (mechanical). The requirement is primarily English for U.S. domestic shipments; many rules require English and Spanish, but the core regulatory requirement is legibility, not necessarily exclusively English text. Thus “text in English” is not an unconditional exception, but among those listed, “text in English” is the least direct regulatory requirement compared to accurate description, emergency contact, and legibility.

In transportation and storage planning, evaluatingweight limitsinvolves considering the weight of the product, packaging materials, pallets, and even fuel to avoid exceeding vehicle or racking limits. “Stock” is a general term for inventory quantity, not a weight-related concern. CLT 4.0 stresses that exceeding legal load or rack weight limits can lead to safety violations, equipment failure, or structural damage. Therefore, logistics personnel must calculate total load weight—including cargo, fuel, and vehicle weight—to comply with DOT and OSHA safety regulations. Ignoring these limits risks fines, product damage, or workplace injury.

JIT emphasizes delivering the right material, in the right quantity, to the right place, at the right time, with the right quality—minimizing waste and inventory. CLT notes how JIT shifts material handling from simple movement to synchronized flow and point-of-use delivery, often using kanban signals and small, frequent replenishments to support lean operations.
