N343643 · 2025-02-12 — The tariff classification of Deoxyribonucleic Acid Sodium Salt (DNA-Na) from Japan
We referred the information provided to our laboratory for review. We regret the delay. The subject merchandise is deoxyribonucleic acid sodium salt (DNA-Na) extracted from salmon milt, CAS No. 68938-01-2. You state that it will be used as a raw material for chemical synthesis. The applicable subheading for the deoxyribonucleic acid sodium salt (DNA-Na) will be 2934.99.9001, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “Nucleic acids and their salts, whether or not chemically defined; other heterocyclic compounds: Other: Other: Other: Other: Other. The rate of…
N332171 · 2023-05-05 — The tariff classification of pHelper-Kan-OTS DNA Plasmid from the United Kingdom
The subject merchandise is pHelper-Kan-OTS DNA Plasmid, used in combination with separate Rep/Cap and gene of Interest (GOI) plasmids, as a biological reagent for triple transfection of mammalian host cell lines to generate Adeno-Associated Virus (AAV) viral vectors for gene therapy applications. The country of origin and export is the United Kingdom. You opine that classification of both the extracted pure plasmids and the plasmids introduced into bacterial cells should be classified in subheading 3002.49.0000, Harmonized Tariff Schedule of the United States, which provides for “Human blood;…
N319797 · 2021-06-09 — The tariff classification of Synthetic RNA from European Union, United Kingdom, or China
You indicate that the subject merchandise consists of synthetic RNA molecules, which are nucleic acids. The artificially made RNA vary in size and usually have a molecular weight between 6 kg/mol to 1500 kg/mol or 20 nucleotides (nt) to 5,000 nt in length. You state that shipments usually consist of less than 1mg. RNA has many scientific applications, including those used for drug development and discovery or bioengineering. They can be used as a reference material for molecular assays, a probe for detecting/capturing DNA molecules, and an expression template in cellular assays. You indicate…
N313545 · 2020-08-19 — The tariff classification of DNA Oligonucleotides from China
You state that the nucleic acids, subject to this request, consist of DNA oligonucleotides, which are small fragments of single stranded DNA, and plasmids that are bigger fully circular double stranded DNA. All of the synthesized DNA is artificial in origin and has been synthesized “in a GENEWIZ lab.” You indicate that the instant products consist of Deoxyribonucleic Acid (CAS# 9007-49-2). The DNA oligonucleotides are artificially made single stranded DNA molecules. They are indicated to have a molecular weight between 5000-70,0000 g/mol or 16-200 nucleotides in length. They are used for…
N305719 · 2019-08-28 — The tariff classification of Ropidoxuridine (CAS No. 93265-81-7) in bulk powder form, from South Korea
The instant product is a pure organic chemical compound called Ropidoxuridine. It is imported in the form of a bulk powder. It is also known as 1-[(2R,4S,5R)-4-hydroxy-5-(hydroxymethyl) oxolan-2-yl]-5-iodopyrimidin-2-one. It is identified also by CAS No. 93265-81-7. Ropidoxuridine is indicated for use in cancer radiation therapy. It is currently in Phase I clinical trials. The applicable subheading for the Ropidoxuridine in bulk powder form will be 2934.99.9001, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “Nucleic acids and their salts, whether or not…
