Import duty = CIF value × duty rate, where CIF value = goods value + international freight + insurance (WTO customs valuation basis). Within this tool the rate is a chapter-level (HS-2) estimate; the actual rate depends on the destination’s 10-digit HTS classification and final customs determination.

Import VAT = (CIF value + duty) × the destination VAT rate, following the EU VAT Directive taxable amount rule. The US has no federal import VAT; rates differ by country (Germany 19%, UK 20%, etc.). For some destinations such as Brazil, additional state/sales taxes apply and are included in the VAT line.

Under Incoterms 2020 the seller’s obligation boundary rises step by step: EXW — the seller only makes goods available at the factory (quote = goods value); FOB — the seller delivers to the port of shipment (adds China inland freight, export customs and origin handling); CIF — the seller also covers international freight and insurance; DDP — the seller bears all costs to the buyer’s door (adds import duty, VAT, destination handling and delivery). The tool’s main total is always the seller quote for the selected term; costs not borne by the seller are shown as "buyer extra".

Chargeable weight = max(actual weight, volumetric weight), where volumetric weight = volume (CBM) × 167 (IATA convention). Example: 500 units × 0.05 CBM = 25 CBM → volumetric weight 4,175 kg; if the actual weight is 1,000 kg, you are billed on 4,175 kg.

Sea freight (LCL) is billed per CBM; this tool applies a 1 CBM minimum, consistent with international LCL forwarding practice, so small shipments never show a zero freight.

It is a quoting simplification: the common market practice is CIF × 110% (including 10% margin) × rate, and 0.3% is a reasonable industry-average estimate. Actual premiums vary by cargo type (electronics, ceramics, dangerous goods), carrier and insured value.

Under DDP (Delivered Duty Paid) the seller bears everything: goods value, China inland freight, export customs, origin handling, international freight, insurance, import duty, import VAT, destination handling and door-to-door delivery. The buyer only receives the goods, so DDP is the highest quote but the lowest buyer risk.

The tool is for fast quoting and early planning: duty rates are chapter-level estimates, fixed fees are estimates, and it does not include Section 301/232 surtaxes, US MPF and other fees, or live broker charges. For official filing, consult a licensed customs broker and rely on the destination customs authority’s final determination.
