Sodium Sulfate Decahydrate Technical Grade from Japan
Sodium sulfate decahydrate technical grade is a hydrated form of sodium sulfate, often used in heat packs and as a laboratory reagent. It does not meet the specific criteria for Glauber's salt in terms of purity or form, so it is classified as 'other' sodium sulphates under tariff item 2833.19.00. The product is a separate chemically defined compound with added water of crystallization.

Import Tips
• Clearly state the grade (technical) and hydrate form on shipping documents to avoid confusion with pharmaceutical or food-grade products
• If the decahydrate is used in consumer goods like heat packs, ensure labelling meets Canadian consumer product safety requirements
• Verify that the product is not classified as a medicament or diagnostic reagent, which would fall under other headings
