Four foundational concepts every cross-border trade professional must understand.
The Harmonized System is an international product nomenclature developed by the World Customs Organization (WCO) since 1988, used by 200+ countries for customs declaration, duty assessment, and trade statistics. The first 6 digits are globally identical. Countries extend with national digits: US uses 10-digit HTS, China uses 10-digit tariff or 13-digit CIQ, most ASEAN nations use 8-digit.
MFN (Most-Favored-Nation) is the baseline WTO-member import tariff, applied by default to goods from fellow WTO members. Lower preferential rates under FTAs or GSP may supersede MFN. General rates (for non-MFN countries) are typically 2-3× MFN. Before export pricing, always verify whether an FTA exists between origin and destination.
Export rebate refunds indirect taxes (VAT, excise) paid during production on goods later exported — an incentive to boost exports. China's State Tax Administration publishes the Export Rebate Library by HS code, with common tiers at 0%, 6%, 9%, 10%, 13%. Rebate rate is strictly tied to HS classification — misclassification can cost rebates or trigger audits.
Import restrictions are destination-country measures beyond tariffs: licensing, quotas, SPS (sanitary/phytosanitary), TBT (technical barriers). Indonesia calls these Lartas, India publishes DGFT schedules, Malaysia's Customs Prohibition Order uses Schedules 1-4. Restrictions matter more than duty — duty is a cost question, restrictions determine whether goods can enter at all. Always verify before shipping.

The HS Code (Harmonized System) is an international product classification maintained by the World Customs Organization (WCO) since 1988, used by 200+ countries. The first 6 digits are globally identical (e.g. 8517.13 = smartphones), while digits 7+ are country-specific extensions: the US uses 10-digit HTS, China uses 10-digit tariff or 13-digit CIQ, most ASEAN countries use 8-digit. HS codes are the basis for customs declaration, duty calculation, and trade statistics.
The first 6 digits (chapter · heading · subheading) are globally standardized by WCO treaty. Digits 7-8 are national subheadings; most countries stop at 8. Digits 9-10 are customs statistical codes: the US HTS uses 10, China's tariff book uses 10. China additionally appends 3 CIQ inspection digits for a 13-digit declaration code.
Three steps: (1) identify the 6-digit international HS — use our AI classifier with a product description; (2) look up the 8-10 digit national tariff in the destination country to get MFN, general, and preferential (FTA) rates; (3) add VAT/GST, excise tax, anti-dumping duties as applicable. We cover 12 countries: US, India, Indonesia, Malaysia, Philippines, Thailand, Vietnam, Japan, Korea, Australia, Brazil, Mexico.
China's export rebate rates are published by the State Tax Administration in the Export Rebate Library, updated multiple times per year, covering all 13-digit HS codes. Common rebate tiers are 0%, 6%, 9%, 10%, 13%. Exporters reclaim VAT previously paid on production inputs. We are integrating China GAC and SAT data sources shortly.
Misclassification leads to wrong duty (under/overpayment), customs delays, cargo holds, and fines. Customs authorities retain post-clearance audit rights (3 years in China, 5 years in the US). Best practices: (1) build an HS archive for recurring SKUs; (2) cross-verify AI classifications; (3) for complex items, request advance rulings (binding pre-classification).
Because the first 6 digits are internationally harmonized, but each country's statistical and tariff needs drive 2-7 digit national extensions. E.g. "men's cotton T-shirts" → US 6109.10.00.04 (10-digit), India 6109.10.00 (8-digit), China 6109100000 (10-digit). When pricing exports, always use the destination country's full local HS.
