Customs & Compliance FAQ
What is an HS code?
Harmonised System (HS) codes classify goods for customs duties and statistics. The first six digits are harmonised globally; countries add further digits. An incorrect HS code can lead to wrong duty rates, audits, or clearance delays.
Who is responsible for import customs clearance?
It depends on the Incoterm. Under DDP the seller handles import clearance; under FOB, CFR, or CIF the buyer typically arranges import customs unless contractually agreed otherwise.
Why do customs hold shipments?
Common reasons include incomplete documentation, valuation disputes, incorrect HS classification, missing licences, physical examination, or outstanding duties and taxes.
How do I find the right HS code for my product?
Start from the product's material composition and function, work through the tariff chapter and heading structure, and check the destination country's national tariff, because codes are harmonised only to six digits and diverge beyond that. Where value or volume is significant, obtain a binding ruling from the customs authority, which converts an interpretation into a decision you can rely on. Misclassification is the most common cause of underpaid duty.
What happens if I declare the wrong HS code?
You may owe underpaid duty plus interest and penalties, and customs can generally reassess retrospectively for several years. Repeated errors can also raise your inspection rate and jeopardise trusted-trader status. If you discover an error, most jurisdictions treat voluntary disclosure far more leniently than the same error found at audit, so correcting it proactively is usually the cheaper path.
Can I claim preferential duty under a free trade agreement?
Only if the goods meet that agreement's rules of origin and you claim preference at entry with valid proof. Origin is not simply where the goods shipped from; it turns on where the last substantial transformation occurred, tested by tariff shift, regional value content, or a product-specific rule. Preference is never automatic, and unclaimed preference is simply lost.
What is an Authorised Economic Operator and is it worth applying?
AEO is a trusted-trader status granted after an audit of your compliance history, record-keeping, financial standing, and security. The benefits are operational rather than financial: fewer inspections, priority treatment when disruptions occur, simplified declarations, and recognition in countries with mutual recognition agreements. It is worth applying if you import or export regularly enough that inspection delays materially affect your supply chain.
