About HS Chapter 28
Chapter 28 of the Canadian customs tariff covers inorganic chemicals. TariffCalc lists 100 10-digit tariff items in this chapter, with MFN (Most Favoured Nation) duty rates ranging from 0.0% to 0.0% (average 0.0%).
100 of 100 items (100%) are duty-free under MFN. Importers from countries with Canadian free trade agreements (CUSMA, CETA, CPTPP, CCFTA, CKFTA, and others) can often import at 0% when rules of origin are met.
Example calculation
| Value for duty (CAD) | $10,000 |
| MFN duty (0.0%) | $0 |
| GST 5% | $500 |
| Total landed (before freight) | $10,500 |

What is HS Chapter 28 in the Canadian customs tariff?▾
Chapter 28 covers inorganic chemicals. It contains 100 10-digit tariff items in the TariffCalc database, with MFN duty rates ranging from 0.0% to 0.0%.
What is the typical duty rate for Chapter 28 imports?▾
The average MFN rate across Chapter 28 is 0.0%. The majority of items (100%) are duty-free (0%) under MFN. Free trade agreements (CUSMA, CETA, CPTPP) may reduce the rate to 0% for qualifying goods.
Do free trade agreements apply?▾
Yes. Most items in this chapter qualify for preferential rates under CUSMA (US, Mexico), CETA (EU, UK), CPTPP (Japan, Vietnam, etc.), and other Canadian FTAs. See each tariff item’s detail page for the full rate-by-agreement breakdown.
How do I calculate import duties?▾
For a CAD $10,000 shipment in this chapter at the average MFN rate (0.0%), duties would be approximately $0, plus 5% GST ($500), for a total of $10,500 before freight. Use the TariffCalc calculator for a precise calculation by tariff item, country of origin, and province.
