HS-6 · Subheading
293355
Heterocyclic compounds; containing a pyrimidine ring (whether or not hydrogenated) or piperazine ring in the structure; loprazolam (INN), mecloqualone (INN), methaqualone (INN), and zipeprol (INN); salts thereof
Heading 2933 — Heterocyclic compounds with nitrogen hetero-atom(s) only
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 293355 when importing or exporting heterocyclic compounds that contain a pyrimidine or piperazine ring, such as loprazolam or methaqualone. For example, a shipment of loprazolam for pharmaceutical use would fall under this code.
This code specifically covers certain nitrogen-containing heterocyclic compounds, including well-known pharmaceuticals like mecloqualone and zipeprol. If you're dealing with similar compounds that do not fit this specific classification, you may need to look at other HS-6 codes under 2933.
Comparatively, HS-6 293354 encompasses heterocyclic compounds with other structures that do not include the pyrimidine or piperazine rings. Understanding these distinctions is crucial for accurate classification and compliance.
When classifying your product, ensure that it matches the chemical structure and intended use outlined in this HS-6. Misclassification can lead to delays in customs clearance and potential fines.
