West Coast Packaging Register · Methodology
How West Coast Packaging Register tracks changes
Follow official notices for packaging compliance managers, brand owners and importers in California and Oregon, with source links and retained record versions.
Official sources
We collect official notices and keep the source documents. The latest three free records and the PRO archive link to their sources and include the collection time, any known publication date and a confidence rating.
Rule status and missing details
Proposals are labelled separately from adopted rules. Dates, penalties and affected groups stay unknown unless the source supports them. Read the original notice alongside the summary for context.
What can I check before subscribing?
Read the latest three records free to inspect their summaries and source links. PRO includes older record content, version history and review tools.

Recorded history
History starts when we first collect a document. Later changes are saved as new versions. Earlier records remain available if a source goes offline. A removed document does not mean its rule was repealed.
Profile matching
We compare your saved profile with the categories named in each notice. A matching category includes the notice; a matching exclusion removes it. Notices with uncertain applicability stay visible for review.
Source checks
We check active sources daily. Each register lists its sources, latest successful checks and any pauses or failures on its coverage page.
