RE: The tariff classification of Dynabeads M-450 and M-280 from Norway.

Dear Mr. Blyskal:

In your letter dated February 22, 1991 you requested a tariff classification ruling.

The beads (both the M-450 and M-280) are polystyrene spheres that contain an iron oxide salt. The polystyrene bead acts as a solid phase for the attachment of antibodies. There are two groups of products as follows:

Group I types are uncoated beads which allow researchers to attach an antibody of their choice directly onto the bead:

Dynabeads M-450 uncoated Dynabeads M-450 Tosylactivated Dynabeads M-280 Tosylactivated

Group II types are beads coated with either secondary or primary monoclonal antibodies for specific blood fraction isolation:

Dynabeads M-450 Sheep anti-mouse Dynabeads M-450 Goat anti-mouse Dynabeads M-450 Sheep anti-rat Dynabeads M-450 Pan-T Dynabeads M-450 Pan-B Dynabeads M-450 CD4 Dynabeads M-450 CD8 Dynabeads M-280 Sheep-anti-rabbit

The applicable subheading for the Group I Dynabeads will be 3903.19.0000, Harmonized Tariff Schedule of the United States (HTS), which provides for Polystyrene, other in primary form. The rate of duty will be 0.9 cents per kilo plus 9.2 percent ad valorem.
