§ FAQFrequently asked questions

What is the US import duty for HTS 2933.35.00.00?
HTS 2933.35.00.00 (3-Quinuclidinol) has a general (MFN) column rate of 5.8%. No Chapter 99 overlays are currently linked to this line. Final duty is determined by CBP at entry.
Does Section 301 or IEEPA tariff apply to HTS 2933.35.00.00?
No Chapter 99 overlay is linked to this line in our current snapshot. That means no Section 301, IEEPA, or reciprocal additional duty is mechanically attached. Always double-check against the latest Federal Register for proclamations that may not yet be reflected in the HTS export.
Could HTS 2933.35.00.00 be subject to antidumping / countervailing duty (AD/CVD) orders?
Organic chemicals (Chapter 29) see a high volume of AD/CVD orders on specific products and countries. Duty does not evaluate AD/CVD automatically — check the DOC AD/CVD dashboard and CBP messages for your specific product + origin before quoting a landed cost.
Why is HTS 2933.35.00.00 a 10-digit statistical suffix?
The 10-digit format is used for CBP entry reporting to track quantity / form; actual column rates are typically set at the 6- or 8-digit parent subheading, and this page inherits those rates. Use the Chapter breadcrumb above to see sibling tariff lines within the same chapter. This page is marked noindex because the duty-relevant signal lives at the parent level.
Is this the binding duty determination?
No. This page is a reference built on USITC + Federal Register open data. The binding classification and duty amount is determined by CBP at entry. AD/CVD and product-specific exclusions require separate review.
