Harkla offers flat-rate shipping for all United States domestic orders. This typically takes 7 to 10 business days to arrive, depending on what part of the United States we are shipping to.
We also offer 3–5 day expedited shipping for an extra charge. This extra fee is determined by the weight of the products.

Please note: Due to the size and weight of our Classroom Kits, customers in Hawaii and Alaska will be responsible for paying the full shipping cost for these products. Standard flat-rate shipping does not apply to Classroom Kits shipped to these locations, and delivery may take up to 14 business days.

Harkla will also cover all return shipping costs associated with returns and refunds. We truly want to make this risk-free for you to purchase and test our products. We are confident you will find them helpful!
