Form Versus Invoice
A consignment arrives with a customs coding form and a commercial invoice. The extracts read as follows.
Coding form: Vendor - Northline Trading Co., Ltd.; Country of origin - Viet Nam; Description - "Ceramic tableware, 1,200 sets"; Quantity - 1,200; Unit price - 12.50; Total value - 15,000.00; Currency - USD; Invoice date - 03/04/2025.
Invoice: Seller - Northline Trading Co. Ltd; Country of origin - Vietnam; Description - "Ceramic tableware (mugs), 1,200 sets"; Unit price - USD 12.05; Total - USD 14,460.00; Date - 04/03/2025; Terms - FOB Haiphong; Freight - USD 900; Insurance - USD 120; Note - "partial shipment: 2 of 3."
The port rule is that a value difference exceeding USD 250 or 2% of invoice value requires a correction before release.
1. Sort the differences into (a) true discrepancies, (b) formatting or ambiguity that you cannot resolve by inspection, and (c) non-differences. Explain each placement.

(a) True discrepancy - one, and it is arithmetic
Unit price 12.50 vs 12.05. Both totals are internally consistent:
- Form: 1,200 × 12.50 = 15,000.00 ✓
- Invoice: 1,200 × 12.05 = 14,460.00 ✓
The form is not mis-added; it is built on a unit price that appears nowhere on the invoice. That is the signature of a transposition (05 → 50), possibly carried across from another file.
Magnitude: 15,000 − 14,460 = USD 540, which is 540 ÷ 14,460 = 3.73%. It exceeds both triggers (USD 250 and 2%).
(b) Ambiguity - cannot be resolved by looking
- Dates 03/04/2025 vs 04/03/2025. Could be the same date in two conventions, or a genuine one-day shift. The document does not tell you which. Ask; do not guess.
- "Partial shipment: 2 of 3." This may mean the 1,200 sets are two-thirds of an order, or that two of three containers shipped. It bears on whether 1,200 is the correct declared quantity, but it is not itself an error.
(c) Non-differences
- "Viet Nam" vs "Vietnam": the same country, two spellings. Do not flag an origin error.
- "Ceramic tableware" vs "ceramic tableware (mugs)": the invoice is more specific, not contradictory. Use the specific description; that is an improvement, not a discrepancy.
- Freight and insurance shown separately under FOB terms: a real feature of the invoice, but irrelevant to the 540 gap - do not use it to explain an error it did not cause.
2. Apply the port rule. State the required action and list, in order, what you would ask the broker to confirm.

Rule applied
Variance of USD 540 is above USD 250 and above 2% (it is 3.73%). A correction is required before release.
Required action
Obtain a corrected declaration matching the invoice, or a written explanation from the broker supported by a revised invoice if 12.50 is in fact correct. Release does not proceed on the uncorrected form.
Why, even though the error runs against the importer
The form overstates value, so the importer would pay more duty, not less - which makes deliberate undervaluation unlikely and supports a transposition. That is a good reason not to treat it as an enforcement matter. It is not a reason to leave it: the declaration must be accurate, and a transposed unit price may mean figures from a different file have been used, which contaminates other fields you have not checked.
Ask the broker, in this order
- Which unit price is correct, and can a corrected invoice be issued if the invoice is the wrong document?
- Does 1,200 sets represent the full order or the "2 of 3" portion - and if the latter, what is the quantity in the remaining portion?
- Which date convention is used (day/month or month/day), so the file date can be recorded correctly?
- Whether the same 12.50 figure appears on other entries prepared by this broker in the same period - a pattern, if present, matters more than the single instance.
Confirm in writing, correct the entry, then release.
