Freight Forwarding & Incoterms: Key Terms Explained in Detail

Not Otherwise Specified (NOS) is a general description used in transport and customs documentation when a product does not clearly fit into a specific classification or detailed code. It acts as a fallback category, allowing goods to be declared when no exact description is available. NOS helps ensure shipments can still be processed without being delayed due to missing or overly specific classifications.

In logistics and customs, NOS is commonly seen in tariff schedules, dangerous goods descriptions, and shipping documents. While it allows flexibility, it usually triggers closer scrutiny from authorities. Customs officers may request additional details to confirm the nature, use, or composition of the product. This is because NOS classifications provide less clarity than precise product descriptions.

Using NOS should be done carefully and only when necessary. Overuse or incorrect use may lead to delays, reclassification, or penalties. Providing supporting documents such as product specifications or material safety data sheets can help reduce risks. Clear communication ensures smoother clearance even when NOS is applied.

Overall, NOS serves as a practical tool to keep shipments moving when exact classifications are unavailable. However, accurate and detailed descriptions are always preferred. When used correctly, NOS supports compliance while maintaining flexibility in complex trade scenarios.
