§ FAQFrequently asked questions
- What is the US import duty for HTS 3918.10.10.20?
- HTS 3918.10.10.20 (Vinyl tile consisting of a rigid solid polymer core) has a general (MFN) column rate of 5.3%, plus 1 active Chapter 99 overlay(s) that may apply depending on origin (for example, Section 301 or IEEPA actions). Final duty is determined by CBP at entry.
- Which Chapter 99 rules are currently linked to HTS 3918.10.10.20?
- The following rules are attached in our snapshot: 9903.88.03 (section301) — section301. Each rule has its own country scope and effective dates — check the rule detail on this page for the additional rate and status before applying it to your shipment.
- Are there material-origin nuances for plastics or rubber under HTS 3918.10.10.20?
- Chapters 39–40 classifications depend heavily on polymer composition, form (primary / semi-finished / article), and end use. A single product line can shift to a very different subheading based on additive content or processing step — double-check the chapter notes before finalizing.
- Why is HTS 3918.10.10.20 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.
