A list whose authority is three Treasury Decisions
On this page10
The section does not claim to be the source of its own list
All articles are listed in Treasury Decisions 49690, 49835, and 49896. So the regulation reproduces a list that was settled administratively and points at where it came from.
And it tells a reader how to see what has changed since
A reference different from the foregoing indicates an amendment. Which turns the citations beside individual entries into a change log embedded in the list.
Several entries carry one
Flooring and sawed lumber both cite Treasury Decisions 49750 and 50366(6). Fish hooks cite 50205(3). Works of art cite 66-153. Each of those is an entry that was altered after the original three.
Which is an unusually honest way to publish a list
Most regulations present a list as a single current text and leave the history to the source notes. This one makes the provenance of each entry visible in the entry itself.
The age of the list shows in what is on it
Hairnets. Phonograph records. Bodies, harvest hat. Briarwood in blocks. Effects, theatrical. Covers, straw bottle. Cellophane and celluloid in sheets, bands, or strips.
And that is not a criticism of the list
A list of classes of goods that do not usefully carry a marking ages the way the goods do. The categories that are still commercially live are still on it, and the ones that are not have done no harm by remaining.
The structure is a list of classes rather than of products
Articles of a class or kind listed below. So an entry is a category and the question for any particular article is whether it falls within one, which is a tariff classification question.
Which is why nothing on these pages says anything is on the list
Whether a particular bead, button or brad is an article of a class or kind described in an entry is a determination about tariff classification. A packaging catalog has no standing to make it.
What the pages can do is read the list
Which is worth doing, because the drafting of individual entries is the interesting part: three carry a dimension, five carve something back out, and the rest are bare category names.
