This post may not be music to your ears, and may seem esoteric, but it addresses a very practical feature of international trade that, improperly done, can put a company into hot water. How do you make sure that your product is properly classified for customs purposes? That may not seem like a big thing, but a mistaken classification can mean vastly higher customs duties or taxes that have to be paid by either you or your overseas customer. Either way, the mistake likely comes out of your bottom line. And I’ve seen estimates that products are misclassified between 30% and 50% of the time.
My friends at the Federation of International Trade Associations (FITA is in my links to the right) put out an article this week about how goods are classified for international shipments. I’ll summarize, add some comments from experience and provide an additional link or two you may find useful.

In Brussels since 1953
There is an international scheme for classifying products. There were earlier versions under other names, but the current one is called the Harmonized System and is maintained by the World Customs Organization. The WCO is not to be confused with the WTO, though they work well together on customs and classification issues. I participated in negotiating the WTO’s Agreements on Customs Valuation and on Rules of Origin (a subject we’ll likely take up one day), and WCO oversees technical aspects of both those agreements. WCO is a forum for 176 customs administrations (that means nearly universal membership) to talk out their differences in administration and interpretation of customs-related issues. It’s one of those unseen operations that keeps international trade going as smoothly as possible.
I won’t say that WCO’s work is riveting, but consider what they are up against. Nearly every country levies customs duties and none that I know of has a simple across the board tariff that is the same for all products. That means that each customs administration needs a method for classifying products and differentiating them so that the proper tariff is applied. It used to be that this system was totally different for every country and that exporters often had little idea what to expect when their shipments got to another border. The lack of any standardization meant that each company had to develop expertise in whatever crazy system a target market might use – and they often got it wrong. (Many years ago, for a brief while, I was the U.S. Government’s expert on the foreign trade regulations of Ethiopia and received lots of questions on tariffs and customs classification. Ethiopia had not yet modernized its system, and its tariff schedule had no logical arrangement. Their duties were listed in the chronological order that the government had decided to apply a tariff. A thorough nightmare.) The Harmonized System is a brave attempt to bring order out of such chaos, something at which it has succeeded amazingly well.
Consider the problem. How many thousands of products move in international trade? I have no idea. And classifying these products is akin to the problems faced by scientists in classifying species. You need a system so that everybody knows what is happening. The Harmonized System does this by dividing all products into 96 chapters and then subdividing those chapters to get greater and greater detail. The HS uses a numeric system with each additional digit developing more and more detail. I’ll give you an example: Chapter 95 covers “Toys, games and sports requisites; parts and accessories thereof.“ But that covers a lot and you are preparing a shipment of playing cards, so you look at Chapter 95 to see if you can drill down to what you need. The HS goes to 95.04 – “Articles for funfair, table or parlour games, including pintables, billiards, special tables for casino games and automatic bowling alley equipment.“ That doesn’t quite do it, but you are in luck. The HS goes to six digits and at 95.04.40 you discover your classification: “Playing cards.”
The fun doesn’t necessarily stop there. Most countries use the HS, but for some products they want to break things down even further (perhaps wanting to separate playing cards for children’s games from cards used in a casino), so many countries use eight digits or even more, defined solely by that country. But the HS gets you most of the way there with six digits and allows you to knowledgeably work with the tariff schedules of most countries, discovering what duty your shipment might face. This can be vital to your pricing for a given market, plus it is your responsibility to identify the classification you think your product belongs in. That does not mean that the customs officer looking at your shipment will agree with the classification you find, but it gives you a starting point for the ensuing discussion – especially if you can show a history of using that classification in other markets, too. The whole idea is to make the movement of goods more predictable.
The harmony, however, is not complete. For reasons of their own, some countries choose to use variations on the HS as the foundation of their tariff schedules. The United States, for instance, uses its Schedule B classification system for exports and the Harmonized Tariff Schedule of the United States for imports. The latter is almost identical to the HS, but adds more digits. Schedule B does the same, but they don’t quite match up. You can find a concordance between the two systems here.
There is also an automated on-line system that, for a small fee, helps you identify your HS classification. I have had good luck with it – and the U.S. Bureau of the Census uses it as their on-line search engine for Schedule B. That seems a fair recommendation.
