Frequently asked questions
Does HS 28444 have one duty rate?
Radioactive elements and isotopes and compounds other than those of subheading 2844.10, 2844.20 or 2844.30; alloys, dispersions (including cermets), ceramic products and mixtures containing these elements, isotopes or compounds; radioactive residues: is an intermediate classification, not a complete eight-digit tariff item. 7 child tariff lines are available. Select the specific child item before determining the duty rate; CBSA classification is authoritative.
Can CUSMA or other preferences apply under HS 28444?
Preference depends on the exact eight-digit tariff item, qualifying country of origin and origin proof or certification. Consult the linked child tariff lines for T2026-2 MFN and preferential rates. Surtaxes and GST/HST/PST must also be checked for the specific item and origin.
