HTS 3815: Reaction initiators, reaction accelerators and catalytic preparations, not elsewhere specified or included
Heading 3815 of the Harmonized Tariff Schedule of the United States has 8 ten-digit statistical numbers. A US entry line in ACE needs the full ten digits, with the quantity in kg.
Check additional duties before you file
- If the goods are made in China, check Section 301 duties under HTSUS heading 9903.88, on top of the general rate, and any exclusions.

Common paperwork mistakes with heading 3815
- The invoice shows the exporter's own code. Only the first six digits are shared worldwide; the US number has ten. Check every line against the list above.
- The quantity is in the wrong unit. These lines report quantity in kg, which may not match the invoice's cartons, sets or pieces.
- The packing list and the bill of lading disagree on cartons or gross weight, which can lead to holds and exams.
- The manufacturer's name and address are missing, so the MID cannot be built from the documents.
Look up any ten-digit number, or read the guide to invoice and packing list mismatches.
Check the whole shipment, not one number
