3813

Analysis

Heading 3813 of the Harmonized Tariff Schedule covers preparations and charges for fire extinguishers; charged fire-extinguishing grenades. It has 2 tariff lines.

1 of its 2 lines with a percentage rate are duty-free at the general rate (50%) and 1 are dutiable, from duty-free up to 3.7%. The median line pays 1.85%.

Its lines are 3813.00.10 for consisting wholly of inorganic substances (duty-free) and 3813.00.50 for preparations and charges for fire extinguishers; charged… (3.7%).

Its median rate of 1.85% sits at the 25th percentile of the headings in chapter 38.

By Census's concordance, most of its statistical lines are made by All Other Miscellaneous Chemical Product and Preparation Manufacturing (325998). Those are the NAICS industries a US producer of these goods would report under.

The heading text decides whether a product belongs here at all (General Rule of Interpretation 1); the subheadings and lines below it only apply once that is settled. Section and chapter notes can override the heading wording, so read them for borderline goods.
