Commercial vs Proforma Invoice for Customs Clearance

The container has landed, the broker has the packing list and the bill of lading, and the only invoice in the shipment folder says "Proforma" across the top. It was the supplier's quotation, sent before the purchase order was confirmed, and the unit price on it is three weeks out of date. The broker files anyway, the entry clears, and two months later the real invoice turns up in accounts payable at a higher price than customs ever saw.

That gap between the document customs relied on and the sale that actually happened is where penalties, bond claims and reassessment notices come from. Knowing which invoice each market expects, when a substitute is acceptable, and what it costs to file on one turns a recurring clearance argument into a checklist step that the trade desk can run before the goods sail.

• What this guide covers: what separates the two documents, the data elements a US entry invoice must carry, when CBP and Indian customs accept a substitute, and how goods with no sale are valued.
• What it adds: a worked entry in dollars and rupees showing the value gap, a timed clearance failure at an inland depot, and a pre-shipment checklist for exporters, importers and brokers.

Proforma or commercial: the document that records an actual sale

A commercial invoice evidences a completed sale between a named seller and buyer at a price actually paid or payable; a proforma invoice is a statement of expected or estimated value. Customs in both the US and India values imported goods from the sale, so the commercial invoice is the default, and a proforma is a substitute that carries extra conditions.

The confusion starts because exporters use the word "proforma" for two different documents. One is the pre-sale quotation sent to the buyer to open a letter of credit or obtain an import licence. The other is the substitute invoice that US regulations describe in 19 CFR 141.85, prepared when no seller's invoice is available. Only the second has a defined place in a US entry, and even then it must be replaced or justified later.

Ten invoice data elements 19 CFR 141.86 expects on a US entry

A US entry invoice must answer ten questions under 19 CFR 141.86(a), and a quotation-style proforma usually fails three of them: the price actually paid, the itemised charges, and the date and place of sale. Checking those three fields before filing catches most substitute invoices that would otherwise slip through as if they were final.

• Port of entry: the US port to which the merchandise is destined, under paragraph (a)(1).
• Sale facts: the time, place and person by whom and to whom the goods were sold or agreed to be sold, or shipped if not sold, under (a)(2).
• Detailed description: the name each item is known by, grade or quality, and the marks, numbers and symbols used by the seller or manufacturer, under (a)(3).
• Quantities: in the weights and measures of the country of shipment or of the United States, under (a)(4).
• Purchase price per item: in the currency of the purchase, under (a)(5); for goods not sold, the value per item in the currency usually used, under (a)(6).
• Kind of currency: a legacy element in (a)(7) that most invoices satisfy by naming the currency.
• Itemised charges: freight, insurance, commission, cases, containers, coverings and cost of packing, each by name and amount, under (a)(8).
• Export rebates: any rebates, drawbacks and bounties allowed on exportation, separately itemised, under (a)(9).
• Country of origin: under (a)(10).

The rest of the section adds requirements that matter during an examination. Paragraph (d) requires the invoice and attachments in English or with an accurate English translation. Paragraph (e) requires the invoice to state what each package contains, which is why a packing list is usually attached. Paragraph (g) requires every discount from list or base price to be shown, and paragraph (j) requires the name of a responsible employee of the exporter who knows the transaction.

US entry invoices are checked by the customs broker against 19 CFR 141.86(a), which lists ten elements including the purchase price per item in the currency of purchase, every charge itemised by name and amount, and the country of origin. A quotation that omits even one of the ten is not a complete commercial invoice.

Paragraph (c) covers goods sold while in transit. The broker must file the original invoice under which the goods began their journey to the United States, plus the resale invoice or a statement of sale. If the original invoice cannot be obtained, a pro forma invoice showing the values and transaction reflected by the original may be filed instead, which is one of the few places the regulation itself invites a substitute.

When CBP accepts a pro forma and the 1.5x bond that comes with it

CBP takes a pro forma invoice in two situations: where 19 CFR 141.83(d) says no commercial invoice is required but a value is still needed, and where the importer cannot produce the required invoice at entry for reasons beyond its control under 19 CFR 141.91. The second route costs money: a bond at one and a half times invoice value, and a deadline.

Under 141.83(c)(1), a commercial invoice must be filed for each shipment not exempted by paragraph (d). Paragraph (d) lists exempt categories, such as merchandise not intended for sale or any commercial use in its imported condition, and says that where no invoice or bill is available, a pro forma or substitute invoice under 141.85 is filed. CBP may also accept a copy of a commercial invoice in place of the original under 141.83(c)(2).

1. Cause beyond control: CBP must be satisfied that the importer could not produce the required invoice for reasons outside its control.
2. Written declaration: the importer files a declaration that it is unable to produce the invoice.
3. Substitute documents: any seller or shipper invoice in its possession, or a pro forma under 141.85, with enough detail for examination, duty estimation and statistics.
4. Bond for production: a bond on CBP Form 301 containing the conditions of 19 CFR 113.62, in an amount equal to 1.5 times the invoice value.
5. Deadline: the required invoice must be produced within 120 days after the entry summary is filed; where it is needed only for statistics, within 50 days after the entry summary was due.

The 141.85 form is more demanding than many importers expect. The preparer must state whether the goods were purchased or agreed to be purchased, the basis on which prices were stated, the unit and total prices in the currency of the transaction, which charges are included, the country of origin, and an undertaking to file immediately any other invoice received. It is signed with the preparer's name, title, firm and date, so it is a sworn statement of value, not a draft.

Shipments with no sale: samples, warranty swaps and repair returns

When nothing is sold, there is no transaction value, so the value on a proforma must come from an alternative valuation method, not from the word "free". Writing "no commercial value" or a token figure on a no-charge invoice is the most common substitute-invoice error, and it is a valuation error rather than a paperwork one.

US law values imports first at transaction value: under 19 U.S.C. 1401a(b)(1), the price actually paid or payable when sold for exportation to the United States, plus packing, selling commissions, assists, royalties and resale proceeds accruing to the seller. A free warranty replacement or a trade-show sample has no such price. The statute then moves through transaction value of identical merchandise, similar merchandise, deductive value and computed value, in that order, before a fallback method.

India follows the same structure from the WTO Valuation Agreement. Rule 3(1) of the Customs Valuation (Determination of Value of Imported Goods) Rules, 2007 makes the transaction value, adjusted under Rule 10, the value of imported goods, subject to Rule 12. Where there is no sale, the officer proceeds sequentially through Rules 4 to 9: identical goods, similar goods, deductive value, computed value and the residual method.

The table is a starting map, not a ruling. Exemptions and partial-duty provisions for repaired or returned goods sit in tariff headings and notifications that differ between the markets, and the importer must confirm the specific provision before relying on any row. What stays constant is the principle: the proforma must explain how its number was reached.

India's bill of entry: declaration, Rule 11 and provisional assessment

An Indian importer signs a declaration of truth on the bill of entry and supports it with the invoice; if the final invoice is not available, the realistic outcomes are a query, a provisional assessment against security, or a rejected value. A proforma alone does not stop the bill of entry being filed, but it moves the risk onto the importer's declaration.

Section 46(4) of the Customs Act, 1962 requires the importer presenting a bill of entry to make and subscribe to a declaration as to the truth of its contents and to produce, in support, the invoice, if any, and other prescribed documents. Rule 11 of the 2007 Valuation Rules then requires a declaration disclosing full and accurate details of value, and any other statement or document the proper officer considers necessary, such as the manufacturer's invoice where goods come through an intermediary.

• Reason to doubt: Rule 12 lets the proper officer ask for further information where there is reason to doubt the truth or accuracy of the declared value, and if the doubt remains, the transaction value is not accepted and the officer moves to Rules 4 to 9.
• Provisional assessment: Section 18 allows provisional assessment where necessary documents have not been produced or further enquiry is needed, on the importer furnishing security for any shortfall between final and provisional duty.
• Wrong declarations: Rule 11(3) applies the Customs Act provisions on confiscation, penalty and prosecution where a wrong declaration, statement or document is furnished.

Indian bills of entry filed on a proforma rest on the importer's Section 46(4) declaration of truth and the Rule 11 value declaration under the Customs Valuation Rules, 2007. Pending a final invoice, Section 18 provisional assessment against security applies, and a later 7% price rise needs reassessment.

India's pre-sale proforma has a second life outside customs. Banks issuing a letter of credit or processing an advance import remittance commonly ask for the supplier's proforma, so the trade desk often already holds one when the goods ship. That convenience is the trap: the document is on file, it shows the right parties and goods, and it is easy to attach to the bill of entry even though the price on it was never the price paid.

Currency, exchange dates and charges both invoices must separate

The invoice currency and the itemised charges decide the rupee or dollar value as much as the unit price does, and a quotation-style proforma often states a lump-sum CIF price with no split. Insist that every invoice itemises freight, insurance and packing, because the US and India treat those lines in opposite directions.

US transaction value excludes the costs of international transport, insurance and related services from the country of exportation to the place of importation, under 19 U.S.C. 1401a(b)(4)(A). India includes them: Rule 10(2), as substituted by Notification No. 91/2017-Customs (N.T.) of 26 September 2017, adds transport, loading, unloading and handling to the place of importation, and insurance, with deemed percentages where the cost is not ascertainable. Our import landed cost guide for India works through those fallbacks in full.

Value gap from filing on a proforma (both markets)

  dV   = Q x (P_final - P_proforma) x ER        (converted value difference)
  dD   = dV x d                                 (duty difference at rate d)
  B_US = 1.5 x Q x P_proforma                   (19 CFR 141.91 production bond)

  Q           = invoiced quantity
  P_final     = unit price on the commercial invoice
  P_proforma  = unit price on the substitute or quotation
  ER          = exchange rate: 1.00 in the US (USD invoice);
                India: rate in force on the bill of entry date (Section 14)
  d           = applicable duty rate (illustrative in this article)

Tolerance rule: hold the entry for review when |dV| / (Q x P_final x ER) > 0.5%

The half-per-cent hold threshold in the block is an internal control choice, not a legal figure. Pick a figure the broker and importer agree on, record it in the brokerage instructions, and apply it whenever the final invoice arrives after release, so that every difference above it leads to a correction request rather than an argument about materiality.

Exchange dates also differ. India converts at the rate in force on the date the bill of entry is presented under Section 46, as Section 14 of the Customs Act provides, using Board-determined rates. The US converts at the rate for the date of exportation, which 19 CFR 159.32 fixes by reference to 19 CFR 152.1(c). A proforma in one currency and a final invoice in another therefore changes the converted value even when the unit price holds.

Worked entries: a priced proforma against the final invoice

A 7% price difference between the quotation and the final invoice produced a duty shortfall in both markets, plus a bond in the US and a security in India, on a modest 600-unit order. The figures below are illustrative, including duty rates and exchange rate, but the arithmetic follows the rules cited above.

The shipment is 600 hydraulic hose fittings. The supplier's proforma quoted USD 36.00 per unit; the commercial invoice, issued after a raw-material surcharge, bills USD 38.50. In the US case an American importer buys from an Indian exporter on FCA terms; in the India case an Indian distributor buys the same fittings from a US exporter, with freight of USD 1,050 and insurance of USD 150 both documented.

The duty gap looks small, which is why it is ignored. The exposure is the declaration, not the $52.50: an importer that routinely files on quotations has a pattern of understated values across every entry, and a customs audit will extrapolate. The consequential IGST on the India side is a credit for most importers, and our guide to IGST on imports and input tax credit covers how it reaches the credit ledger.

Twenty-six hours at an inland container depot over one proforma

A bill of entry filed on a proforma cleared nothing faster; it moved the delay from the supplier's billing desk to the customs queue and added a security deposit. The trace below shows a typical sequence at an inland container depot, with illustrative document numbers.

1. Monday 09:10, filing: the broker files bill of entry BE-4471820 against proforma PI-0417, which states "CIF Nhava Sheva USD 22,800" as a lump sum with no freight or insurance split and a validity date two months past.
2. Monday 13:45, query raised: the assessing officer queries the value, citing the expired proforma and the missing charge split, and asks for the final commercial invoice, the freight certificate and the insurance policy.
3. Monday 17:30, supplier chased: the importer's buyer emails the US exporter; the invoice was issued four days earlier to the AP mailbox as CI-2291 at USD 38.50 per unit and never forwarded to logistics.
4. Tuesday 10:20, reply filed: the broker uploads CI-2291 with freight and insurance documents; the declared value rises by ₹1,32,000 and the importer pays the differential duty, while the depot clock for free storage keeps running.
5. Tuesday 11:15, release and root cause: out-of-charge is granted; the root cause is logged as "commercial invoice received by AP, not linked to the shipment record", and the purchase order goods receipt is held until the invoice price variance is approved.

Invoice checks software can run and decisions a broker must own

Field-presence checks, value comparisons and deadline tracking can run automatically against every entry; deciding whether a substitute invoice is justified, and which valuation method applies to a no-sale shipment, must stay with a licensed broker or the importer's compliance lead. Text extraction speeds up the reading but does not make the call.

Customs brokers screening invoices for US entries and Indian bills of entry can automate the proforma-title check, the 141.86(a) element check and a 120-day production tracker under 19 CFR 141.91. Choosing a valuation method under 19 U.S.C. 1401a or Rules 4 to 9 of the 2007 Valuation Rules remains a licensed person's decision.

Two adjacent workflows share data with this one. Export-side instructions that carry the invoice value into the filing are covered in our shipper's letter of instruction guide, and the post-release match of entry value, invoice and duty paid sits in our CBP ACE entry reconciliation and three-way match article, which starts where this one stops.

Pre-shipment invoice checklist for exporters, importers and brokers

Most proforma problems can be prevented before the goods leave the origin warehouse, by making the commercial invoice a release condition for the shipment rather than a document that follows it. The checklist below assigns each step to a party and gives the evidence that proves it was done.

Start with the lanes where suppliers habitually ship ahead of billing, typically new vendors and urgent spares, and measure the share of entries filed on a substitute each month. When that share stops falling, the remaining cases are usually genuine no-sale shipments, which need a valuation memo rather than a faster invoice. More customs and trade documentation guides are collected on our Logistics and Supply Chain hub.

If your team is choosing broker software or a trade compliance platform that should enforce these invoice checks, our RFP builder turns the checklist above into requirements you can send to vendors and score their responses against.
