Check additional duties before you file
- Goods under this heading are often covered by antidumping or countervailing duty orders (steel threaded rod and fasteners). Confirm scope, country and manufacturer in CBP's AD/CVD case search. A missing case number is a common reason for penalties.
- Steel and aluminum articles here may carry Section 232 duties. The entry can need the Chapter 99 number, the metal value and the country where the metal was melted and poured, or smelted and cast.
- 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 7318
- 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
FreightProof reads the invoice, packing list and bill of lading together, validates every HTS number and container, builds the MIDs and flags what does not match — in about two minutes.
