Phytosanitary Certificates and Plant Import Permits Explained
A phytosanitary certificate is an official plant health document issued by the exporting country's national plant protection organization, and the importing country decides when it is needed. This guide covers who issues it, how US import permits fit in, how ePhyto works and what happens to cargo that fails inspection.
Mexican Pedimento, IMMEX and Customs Brokers Explained
The pedimento is the customs declaration behind every Mexican import or export, and IMMEX is the program that lets manufacturers import inputs without paying duty first. This guide explains both, who may file, what changed for 2026, and where the US entry takes over.
UK Import Customs Declarations: CDS, EORI and Postponed VAT Explained
To import goods into Great Britain you need a GB EORI number, a customs declaration made on the Customs Declaration Service (yourself or through an agent), and a plan for paying duty and import VAT. This guide covers each step and what has changed at the border, as of 6 October 2026.
ISF 10+2 (Importer Security Filing) Explained: Who Files, What and When
The Importer Security Filing, known as ISF or 10+2, is the advance data filing US Customs and Border Protection requires for ocean cargo bound for the United States. This guide covers who files, the ten importer elements, the deadline, bonds, penalties and a practical forwarder workflow.
FDA Prior Notice and FSVP: What Food Importers Must File Before US Customs
Food shipped to the United States needs more than a customs entry. FDA wants a Prior Notice filed in advance, a registered foreign manufacturer, and a named FSVP importer, and a gap in any of them can strand the cargo at the port.
The Harmonized System Revision Cycle Explained: Why HS 2027 Became HS 2028
There is no HS 2027. The World Customs Organization pushed its latest Harmonized System revision back a year, and the edition that actually takes effect, HS 2028, enters into force on 1 January 2028. Here is how the revision cycle really works, and what an importer or forwarder needs to check when it lands.
Country of Origin Marking Rules Explained: Marking vs Duty Origin
A product can be legally marked "Made in Vietnam" and still fail to qualify as Vietnamese under a free trade agreement at the very same time, because marking and duty preference are decided by two different legal tests. Here is what the marking rule actually requires, where it does not apply, and what it costs to get wrong.
Inward and Outward Processing Relief: EU and UK Duty Suspension Explained
Inward and Outward Processing Relief are EU and UK customs procedures that suspend or reduce duty before it is paid, not refund it afterwards. Here is what each actually requires, and why the paperwork burden is the part importers underestimate.
Assists, Royalties and Customs Value: What You Must Add to the Price Paid
First sale lowers the price you start from. This is the mirror-image problem: the assists, royalties, resale proceeds, packing costs and commissions the law requires you to add back on top, and when each one actually applies.
Binding Tariff Rulings Explained: EU BTI vs US CBP Rulings
A binding ruling locks in your tariff classification before you ship, but the EU and US run genuinely different systems, and both cover less than importers assume. Here is how BTI and CBP rulings actually work, what protection they give you, and what they never touch.
Section 321 De Minimis and Type 86 Entry: What Changed
The $800 Section 321 exemption is suspended worldwide and Entry Type 86 has not accepted a new filing since August 2025, and neither the Supreme Court IEEPA ruling nor the litigation that followed brought either one back. Here is what CBP actually requires for low-value shipments now, sourced to the Federal Register and CBP guidance.
AES and EEI Explained: How US Export Filing Works
Most US exports need Electronic Export Information filed in the Automated Export System before the cargo moves. This guide covers who files, when, what goes on the bill of lading, and what a wrong filing costs.
ICS2 and the EU Entry Summary Declaration: What Shippers Must Supply
ICS2 is the EU system that collects safety and security data on every consignment before it arrives. As of September 2026 it covers air, sea, road and rail, and the data you give your forwarder decides whether cargo is stopped.

The EU Deforestation Regulation has been postponed twice, and as of September 2026 it applies from 30 December 2026. Here is who carries the legal duty, what a shipper needs ready, and where a freight forwarder fits.
UFLPA Detentions and the US Forced Labor Import Ban Explained
A UFLPA detention starts a 30-day clock, and the burden of proof sits with the importer. Here is how the forced labor ban works, what CBP asks for, and what shippers and forwarders should have ready before cargo is held.
TIR Carnet Explained: International Road Transit Under Seal
A TIR carnet and an ATA carnet get confused constantly, and the difference matters: one covers goods passing through customs territory under seal on their way to a final destination, the other covers goods that will leave again unchanged. Only one of them is meant for permanent imports.
Tariff-Rate Quotas Explained: TRQs and Your Duty Bill
A tariff-rate quota is not a quota in the sense most people mean. Nothing is barred from entering. What changes is the duty rate, and getting the timing wrong on a time-sensitive commodity can mean paying substantially more than you planned.
Pro Forma Invoice in International Trade Explained
A pro forma invoice looks like an invoice but is legally a quotation, and that distinction matters at three separate points: customs entry, a letter of credit, and getting paid. Here is what CBP actually requires when the real invoice is not ready yet, and where treating the two documents as interchangeable causes real delay.
First Sale for Export: Lowering Your Customs Valuation
When goods move factory to middleman to importer, US customs law lets you pay duty on the earlier, lower price instead of what you actually paid, if you can prove it. Here is how first sale for export actually works, what CBP demands as proof, and why Congress is trying to abolish it this year.
ATA Carnets and Temporary Imports Explained
An ATA carnet moves goods across a border temporarily without paying duty or posting a local deposit. The rules changed in 2026: digital carnets went live in 30 territories on 1 June, and Mexico now demands pre-registration. Here is what a carnet covers, what it costs, and when it is the wrong tool.
Customs Post-Entry Amendments: Fixing a Filing Mistake After the Fact
A wrong value, code, or quantity on a customs entry does not have to become a compliance problem, as long as it is corrected the right way and within the right window.
Free Trade Agreement Certificates of Origin: How to Actually Use Them
A certificate of origin under a free trade agreement only saves duty if the product actually qualifies under the agreement's specific rules of origin, not just because it was made in a member country.

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.
