Check your CPSC eFiling CSV before the Product Registry rejects it
Paste or open your CSV Template V3 file. 18 rules from CPSC's own User Guide for CSV Upload V3 and code lists run in your browser. Nothing is uploaded or stored.
- Row-level fixes, not a failed batch. Every missing header, blank required cell, bad date, comma and over-length value with its row, column and the CPSC guide page that sets the rule.
- Citation and testing-exclusion codes checked. Each code is matched against the CPSC citation and testing exclusion code list (123 + 53 codes), and NOL labs are checked against exclusion codes only.
- Private by design. The check runs locally in your browser. No upload, no account, no AI.
Check my CSV
Save the CPSC Excel template as CSV first (the Product Registry only accepts CSV). Excel files (.xlsx) are not read.
Is my HTS code on the CPSC eFiling list?
Enter 10-digit HTS codes, one per line. The list has 159 CP2 codes (certificate data is required) and 430 CP1 codes (may be needed). It is not exhaustive: a code that is not listed can still need a certificate.
Need the CSV prepared from your test reports?
Fizz Labs can prepare CSV Template V3 data from your test reports and product documents (English, Korean or Japanese) for your US importer. We do not log into ACE or the Product Registry and we do not file for you.
FAQ
Is this an official CPSC tool?
No. Fizz Labs built it from CPSC's public documents (links on every rule). The CPSC Product Registry is the final validator.
Does my file leave my computer?
No. The page counts that a check ran (with a row-count range and whether errors were found), never the content.
Which template version?
CSV Template for Bulk Upload V3 and User Guide for CSV Upload V3 (December 2025), Citation and Testing Exception Codes (September 2026 Update), HTS list dated 09/30/2026. Checked 2026-11-09.
Can you file for me?
No. We do not log into ACE or the Product Registry. We can prepare the CSV data from your documents on request.
Does a clean result mean my product complies?
No. This is a data format checker, not testing, certification, customs brokerage or legal advice.
