How are customs duties and taxes handled for international shipments of microspheres?

Most of our products (with the exception of density marker beads) are sold as a dry powder prepackaged by weight, volume, or count. Every product code and description specifies the amount of material per unit. Price per unit is for that amount of material. One unit is the minimum amount that can be purchased.

To expedite processing and to offer the best value for our customers, Cospheric has negotiated excellent shippping rates (both domestic and international) with major shipping carriers. As a company policy, we do not ship collect to account. Any exceptions to this rule need to be pre-approved prior to placing an order.

We accept returns of unopened stock products in resalable condition within thirty (30) days of purchase with a 15% restocking fee. Please Contact Us for an authorization prior to returning.

Unfortunately, we cannot accept returns on custom made microspheres or on opened/resealed packages.

We guarantee the quality of our products to specifications listed under product descriptions on the website. The information we provide is correct to the best of our knowledge at the date of publication. It should not be viewed as all inclusive, but as a guide only.

Does Cospheric have international distributors for microspheres?

We ship precision spherical particles worldwide out of our California manufacturing facility and encourage customers to order directly from us.

If you are interested in re-selling our products in your country, you are welcome to do so. However, we do not offer distributor agreements, discounts, custom labeling or packaging.

Are all 2000 SKUs of microspheres, nanospheres, and precision spherical particles in stock?

The website is updated daily with the latest inventory information. However, it is possible that multiple orders for the same product might come in on the same day and a specific product might sell out. This happens infrequently. In that case we will email you and offer a recommendation for a substitute product.
