Stopped treating optional customs-broker fees as the only total estimate; marked broker optional; Chinese amountZh; removed wrong 'Per DE filing' period label.
📋 Direct Answer
Import duty is calculated from the customs value and the duty rate for the goods classification (HS code) under the destination customs tariff. Rates and preferences vary by origin and product. Confirm the applicable rate in the official tariff database before quoting landed cost. This page does not assert a single universal duty percentage.

💰 Cost Breakdown
| Item | Cost | Frequency |
|---|---|---|
| Find your HS code | commercial — verify | one-time |
| Look up duty rate | commercial — verify | one-time |
| Calculate duty + import VATTax amount depends on CIF value, duty rate and destination VAT — not a fixed fee | commercial — verify | one-time |

Tariff calculation is additive: Customs Value + Duty + Anti-dumping + Section 301 = assessable value for VAT/GST
Miscalculating one layer cascades errors to all subsequent layers, especially VAT/GST

❌ Misclassifying products with the wrong HS code, leading to incorrect duty rates
💥 Consequence: Wrong HS codes can result in overpaying duties (losing margin) or underpaying (triggering audits, penalties, and retroactive duty assessments).
✅ Fix: Use the World Customs Organization HS nomenclature or your country tariff database to classify products. When in doubt, request a binding tariff ruling from customs authorities.
❌ Shipping without complete customs documentation
💥 Consequence: Missing or incomplete commercial invoices, packing lists, or certificates of origin cause customs delays, storage fees, and potential goods seizure.
✅ Fix: Prepare a checklist: commercial invoice with itemized values, packing list, bill of lading or airway bill, certificate of origin, and any required product certifications.
