Bottom line: Total shipment tariff = the sum of duties calculated for each HS code in a single shipment. HSBot supports adding multiple HS codes at once, calculating and aggregating automatically to avoid errors from manual addition.
In trade practice, a single import often contains multiple products (multiple HS codes): one box might contain wooden chairs, screws, and earphones. Each product has different rates and regulatory conditions, requiring separate classification, separate calculation, and final aggregation to get the true total cost.
Three common problems with manual shipment calculation: 1. Missing items: 10 codes but only 8 calculated 2. Wrong base: Some on CIF, some on FOB, inconsistent basis 3. Forgotten fees: Only calculated duties, missed MPF/HMF
Any single error distorts the total cost, throwing off pricing and profit calculations.
Assume a Chinese shipment with total FOB of $30,000, containing three products:
| Product | FOB | MFN | 301 | 232 | Duty subtotal |
|---|---|---|---|---|---|
| Wooden chairs | $10,000 | 0% | 25% | 0% | $2,500 |
| Stainless steel screws | $10,000 | 0% | 25% | 50% | $7,500 |
| Bluetooth earphones | $10,000 | 0% | 7.5% | 0% | $750 |
| Duty subtotal | $10,750 | ||||
| Shipment MPF (0.3464% × $30,000) | $103.92 | ||||
| Shipment HMF (0.125% × $30,000, ocean only) | $37.50 | ||||
| Total shipment duties | ~$10,891 |
Illustrative figures. Actual rates depend on specific HS codes. Note that MPF/HMF are calculated on total shipment FOB (not per item), making manual calculation error-prone. Use HSBot for real-time calculations.
US/UK data is cached independently, supporting import/export comparison mode.
HSBot supports multi-HS aggregation, automatically stacking all rate layers and fees to provide a complete shipment summary — an efficient tool for calculating cross-border landed costs.
