Would you like to save tens or hundred of thousands

of pounds in shipping fee's each year?


Scitegrity’s powerful tariff coding software is able to determine the relevant import tariff from the chemical structure of your compounds, even for large chemical libraries.

Simply search for, draw or upload a file containing your structures, select your desired country and hit search.  Watch our 90 second demo below to see it in action.

Available as a service, in the cloud, as a webservice or on premises. 




The Harmonized Commodity Description and Coding System, known as the "Harmonized System", "HS" or “Harmonized Tariff Code” was developed by the World Customs Organization (WCO). Over 98% of the merchandise in international trade is classified in terms of the HS.

Chemicals are primarily found in Chapters 28 and 29 and the HS system is used by more than 200 countries and economies as the basis for determining their customs tariffs and international trade statistics for chemicals.

These chapters are around 295 pages long with rules on how to assign duty based on increasingly granular chemical classes, groups, structures and uses and require expert knowledge to identify the lowest applicable duty. Often the wrong duty rate is used, either accidentally, or when larger numbers of compounds need to be shipped, because its not possible to check all of them so instead the highest duty rate tends to be used instead. 

Tariff coder is also able to take into account use and context sensitive information to determine the most appropriate HS code and lowest duty to apply.

Scenario 1

A compound library of 500 chemicals with a value of $250K exported. The supplier cannot manually code this many manually so declares the highest 6.5% import duty rate to prevent risk of tax fraud.

The duty on this is $16,250

However with Scitegrity's Tariff coder the exact duty is calculated at $13,812

A saving of $2,438 for a single shipment

Scenario 2

4 compounds were custom synthesized at the gram scale and shipped to a customer for £110K. The duty was manually determined by the chemist to be 4.8% based on the structures. However she easily missed some relevant parts buried in the 295 pages of the HS rules, additional explanatory notes and country specific rules which allowed the actual duty rate to be declared at 0%.

Scitegrity Tariff coder saved £5,280
