How to Compare Two Aluminum Tin Quotes That Are Not Comparable

The normalisation, written out, with the amortisation worked through at two quantities:

Landed cost/pc = Unit price + (Tooling + Set-up + Samples) ÷ Qty + Freight ÷ Qty + Duty + Regulatory cost

A USD 2,000 tooling charge, on its own:
2,000 ÷ 5,000 = USD 0.40 per piece
2,000 ÷ 50,000 = USD 0.04 per piece

Same charge, same supplier, same tool. A tenfold difference decided entirely by a number that frequently is not written on the quotation at all. Everything below is about the other five terms in that formula and the documents that fix them.

Quote Normalisation Reference Chart

Before the detail, the chart. Seven cost lines, where each usually hides, and what to ask for so it stops hiding. Print this and put it beside two quotations.

Cost line	Where it usually sits	What to request	Quote A vs Quote B
Tooling	A separate line, or silently folded into the unit price	The amount, and the quantity it is amortised over	______
Plate / screen set-up	Often omitted, then invoiced at artwork approval	Per colour, per SKU, and whether repeat runs are charged again	______
Samples	Quoted as a small figure with courier extra	Whether the sample is from the production tool, and whether the charge is credited against the order	______
Export packing	Assumed	Carton spec, units per carton, carton dimensions and gross weight	______
Freight	Outside the quote entirely under EXW or FOB	Named Incoterms rule with the named place, and the carton data to price it	______
Duty	Never in the quote	The HS code the supplier will declare, for the tin and for the lid	______
Regulatory	Never in the quote	For EU imports, whether the goods are in CBAM scope	______

The last two lines are the ones that have changed most in the last eighteen months, and they are the two that no supplier will raise unprompted — not out of concealment, but because they are the importer’s costs, not the exporter’s.

Why a Lower Unit Price Can Be the More Expensive Quote

A quotation is a set of numbers whose boundaries the supplier chose. Two suppliers can draw those boundaries differently and both be acting in good faith. The buyer’s job is to redraw them identically before comparing.

7-Line Quote Normaliser

Line	Normalise by	Quote A	Quote B
1. Unit price at a stated quantity	Restate both at the same quantity — a price for 20,000 and a price for 5,000 are different products	______	______
2. Tooling ÷ quantity	Amortise over the quantity you will actually order in year one, not over the tool’s life	______	______
3. Set-up ÷ quantity	Include every colour and every SKU; ask whether repeats are charged again	______	______
4. Samples	Include the charge and whether it is credited; production-tool samples are worth paying more for	______	______
5. Freight ÷ quantity	Price from the carton data, both quotes on the same Incoterms rule	______	______
6. Duty	Apply the rate for the code that will actually be declared, tin and lid separately if invoiced separately	______	______
7. Regulatory	CBAM for EU imports; any other market-specific cost	______	______

Run it once and the two columns usually converge, sometimes reverse. The 7-Line Quote Normaliser takes half an hour and is the only thing in procurement that reliably changes a decision.

One line deserves a note on how it is often used against buyers. When tooling, set-up, samples and export documents are folded into the unit price, the quotation looks simple and becomes impossible to compare — which is frequently the intention. A supplier who will not separate them is telling you something.

Ask both suppliers to restate their quotation at the same quantity with one-off charges on their own lines, before you look at either number again.

Why “FOB” on a Container Quote Is Usually the Wrong Term

Incoterms® 2020, published by the International Chamber of Commerce, is the current edition. It has eleven rules in two families. Seven are for any mode of transport — EXW, FCA, CPT, CIP, DAP, DPU, DDP — and four are for sea and inland waterway only: FAS, FOB, CFR, CIF.

That second family stipulates a delivery point on board a vessel. Containerised cargo is not handed over on board a vessel; it is handed over at a terminal, days earlier, after which the seller controls nothing but still carries the risk. ICC publishes a dedicated free guidance document, INCOTERMS® 2020 FCA and CPT: Best practice for shipping containers through ports, addressing what it calls the frequent mismatch between the chosen rule and the practical realities of shipping goods in containers through ports. The recommendation is FCA at origin with CPT or CIP to destination.

EXW has its own warning, and this one is in ICC’s own training material: “Traders are strongly encouraged to consider using FCA instead of EXW where the goods are crossing a border,” because under EXW the export responsibilities fall on the buyer, who is frequently not in a position to discharge them.

3-Term Incoterms Check

Check	What to verify	What goes wrong otherwise	Agreed
1. Right family	Containerised goods take a multimodal rule — FCA, CPT, CIP, DAP, DPU or DDP — not FOB, CFR or CIF	Duplicated terminal handling charges, disputes over where risk passed, and a seller carrying risk over cargo they cannot see	______
2. Named place	Every rule takes a named place, and the place is as important as the letters	“FCA China” is not a term; the cost and risk boundary is undefined	______
3. Import clearance capability	Under DDP the seller handles import clearance — ICC notes that some authorities require the local importer to do it, in which case DAP is the correct rule	Goods stuck at destination under a term the seller cannot legally perform	______

One difference worth knowing between two rules that look like a pair: under Incoterms® 2020, CIP requires all-risks Institute Cargo Clauses A cover, while CIF still requires only minimum Clause C cover. Buyers who ask for “CIF with insurance” frequently believe they have bought the former.

Check which Incoterms rule is on both quotations before comparing their prices — two different rules make the numbers non-comparable no matter how carefully everything else is normalised.

Why Nobody Owns the Mould Until Someone Writes It Down

We looked for a standard covering tooling ownership so that we could point buyers at it. There is not one.

ISO publishes no standard on mould ownership. The WCO and UNCITRAL publish nothing on it. ICC’s model contract catalogue — the Model International Sale Contract (ICC Pub. 828E, 2024), the Model Subcontract, the turnkey plant and technology-transfer forms, and the rest — contains no tooling or contract-manufacture form and no tooling-ownership clause. The nearest thing from a recognised body is Orgalim’s Model Form of Contract for Commissioned Development, published in May 2024 for development work undertaken by one party and paid for by the other. Everything else in circulation is law-firm commentary and supplier terms.

The practical consequence is blunt: if your purchase order does not state who owns the tool, ownership is whatever the supplier’s terms — or the supplier’s local law — say it is. Paying a tooling charge does not by itself transfer title to anything.

3-Question Tooling Ownership Lock

Question	Get it in writing on the purchase order	Why a chat message is not enough	Answer
1. Who owns the tool after I pay for it?	A named owner, and whether payment transfers title or buys exclusivity of use	These are two completely different arrangements and both are described as “you own the mould” in conversation	______
2. Where is it stored, and can it be moved?	The physical location, and the notice period and conditions for transferring it	Many factories keep the tool and agree not to run it for anyone else — a normal arrangement that has to be written down	______
3. What happens on termination or insolvency?	Who may collect it, against what outstanding balance, and within what period	This is the scenario in which the answer matters, and the one nobody discusses while things are going well	______

None of this is adversarial. A supplier holding a tool and undertaking not to run it for a competitor is a perfectly ordinary commercial arrangement. The problem is never the arrangement; it is that it was never recorded.

Put these three answers on the purchase order before the deposit moves — not in an email thread, and not after the tool is cut.

Why the Lid and the Tin May Clear Customs as Two Different Products

Under the Harmonized System, an aluminium tin sits in heading 76.12: “Aluminium casks, drums, cans, boxes and similar containers (including rigid or collapsible tubular containers), for any material (other than compressed or liquefied gas), of a capacity not exceeding 300 l, whether or not lined or heat-insulated, but not fitted with mechanical or thermal equipment.” Subheading 7612.10 is collapsible tubular containers; 7612.90 is everything else, which is where a rigid tin lands.

A lid presented separately is a different story. Heading 83.09 covers “Stoppers, caps and lids (including crown corks, screw caps and pouring stoppers), capsules for bottles, threaded bungs, bung covers, seals and other packing accessories, and parts thereof, of base metal”. This is not an interpretation: US Customs ruling NY N300151 classified aluminium canisters to 7612.90.10 and the twist-on aluminium lids for them to 8309.90.0000, at two different duty rates. Where the closure is presented with the container it goes with the container — a UK advance tariff ruling classified aluminium collapsible tubes with plastic caps to 7612 on that basis.

And heading 76.15 — table, kitchen and household articles of aluminium — is the wrong heading for a packaging tin, although it is a common misclassification. It matters more than it used to, for a reason in the next section.

4-Code Classification Gate

Gate	What to establish before shipment	Consequence of getting it wrong	Confirmed
1. The tin’s code	Heading 7612, subheading 7612.90 for a rigid tin; the US line is 7612.90.10 for capacities not exceeding 20 litres, at 5.7% general rate	Wrong duty, and potentially wrong trade-remedy exposure	______
2. The lid’s code	8309 if invoiced separately; with the tin if presented together	Two lines on one invoice can attract two rates — a surprise at entry, not at quotation	______
3. Trade remedies	For the US, whether the line is caught by Section 232 aluminium measures and at what rate under the current annex	Since 6 April 2026 the duty applies to the full customs value regardless of metal content, so a model built on an older basis understates it	______
4. Who declares it	The importer of record is responsible for the classification, whatever the supplier wrote	Relying on a supplier’s code is relying on someone with no liability for it	______

Ask both suppliers which HS code they will state on the commercial invoice for the tin and for the lid, and check it against your own broker’s view before the first shipment rather than after it.

Why an EU Buyer’s Landed Cost Now Has a Carbon Line

This is the newest line in the formula and the one most likely to be missing from a comparison made from a 2024 template.

The EU Carbon Border Adjustment Mechanism, established by Regulation (EU) 2023/956, entered its definitive period on 1 January 2026. The Commission’s own sector guidance for aluminium lists the CN headings in scope: 7601, 7603 to 7608, 7609 00 00, 7610, 7611 00 00, 7612, 7613 00 00, 7614 and 7616 — with a footnote excluding CN 7615, certain household articles, and CN 7602 00, aluminium waste and scrap.

Read that list against the previous section and the consequence is immediate: an aluminium tin correctly classified to 7612 is a CBAM good. The same item misclassified to 7615 is not. Classification is now a carbon-reporting question as well as a duty question.

2-Line CBAM Scope Check

Line	What to establish	Where it lands	Your position
1. Is the good in scope?	The CN heading actually declared — 7612 is in scope, 7615 is not	Determines whether CBAM obligations attach at all	______
2. What does the supplier have to give you?	Embedded emissions data for the goods, from the producer	The importer reports; the data has to come from the factory, so it belongs in the supply agreement	______

Two honest caveats. A de-minimis mass threshold was introduced by the 2025 CBAM simplification package, so small importers may fall outside the obligation — check the current threshold against your own annual tonnage rather than assuming either way. And CBAM is an importer obligation: no supplier quotation will include it, which is precisely why it has to be added during normalisation rather than expected to appear.

For EU duty, the Combined Nomenclature splits 7612 90 further — 7612 90 20 for aerosol containers, 7612 90 30 for containers made from foil not exceeding 0.2 mm, and 7612 90 80 for other, which is where a rigid tin normally sits. Confirm the third-country rate in TARIC for the date of import rather than from any article, this one included; rates and measures change by regulation several times a year.

If you import into the EU, add a CBAM line to your landed-cost model this quarter and ask your supplier now for embedded-emissions data — it takes a factory time to produce it for the first time.

Why the Same Cartons Cost 20% More to Fly With One Carrier

Air freight charges on the greater of actual weight and volumetric weight. IATA’s published general rule divides the shipment volume in cubic centimetres by 6,000 to obtain volumetric kilograms. Express carriers commonly divide by 5,000 — DHL’s published UK rule states length × height × width in centimetres divided by 5,000.

For a low-density product such as tins, where volumetric weight almost always exceeds actual weight, that difference is not academic. The same cartons produce a chargeable weight 20% higher against a 5,000 divisor than against a 6,000 divisor, before anyone changes a single carton.

2-Divisor Freight Check

Step	Calculation	Your cartons
1. Carton volume	L × W × H in cm	______ cm³
2. Volumetric weight, IATA basis	Volume ÷ 6,000	______ kg
3. Volumetric weight, express basis	Volume ÷ 5,000	______ kg
4. Actual gross weight	Weigh a packed carton	______ kg
5. Chargeable weight	The greater of step 4 and the relevant volumetric figure	______ kg

Two practical consequences. First, ask which divisor each freight quote used before comparing them. Second, on a volumetric-charged shipment, carton efficiency is worth more than product weight — a carton spec that fits twelve more tins in the same box reduces the bill directly, and it is a conversation to have with the supplier at quotation, not after the first shipment.

For sea freight, the published benchmark is Drewry’s World Container Index, assessed weekly. Cite the index rather than a figure: individual lanes moved by five per cent week on week in the assessments around the time of writing, so any number printed here would be wrong by the time you read it.

Send the carton dimensions and packed gross weight to both suppliers’ freight forwarders on the same day and require them to state the divisor used.

Why the Approved Sample Is a Legal Document

The sample charge looks like the least important line on a quotation. It is the line that establishes what the goods are contractually required to be.

The United Nations Convention on Contracts for the International Sale of Goods, adopted in Vienna in 1980 and in force since 1 January 1988, applies by default to a sale between parties in different contracting states. Both China and the United States are contracting states. Its Article 35(1) requires the seller to deliver goods “of the quantity, quality and description required by the contract and which are contained or packaged in the manner required by the contract”. Article 35(2) then provides that, unless agreed otherwise, goods do not conform unless they, among other things, “possess the qualities of goods which the seller has held out to the buyer as a sample or model” — subparagraph (c) — and are “contained or packaged in the manner usual for such goods or, where there is no such manner, in a manner adequate to preserve and protect the goods” — subparagraph (d).

3-Clause Conformity Lock

Clause	What it makes contractual	What to do about it	Done
Art. 35(2)(c) — sample or model	The approved sample becomes the standard the goods must meet	Approve a sample from the production tool, sign and date it, and retain one at each end	______
Art. 35(2)(d) — packaging	Export packing is a term of the contract, not a detail	Write the carton spec into the purchase order so “usual” is not left to be argued about	______
Art. 35(3) — buyer’s knowledge	The seller is not liable for a non-conformity the buyer knew or could not have been unaware of at contract formation	Raise defects at sample approval, in writing — accepting a known flaw silently forfeits the point	______

This is why the question “is the sample from the production tool or the sample tool?” is the single highest-value question in a sourcing conversation. A hand-made sample tells you nothing about fifty thousand units, and under Article 35(2)(c) it is nonetheless the thing your claim will be measured against.

Pay the higher sample charge for production-tool samples, and sign and date two of them — it is the cheapest legal protection available in this transaction.

Why Two “ISO 9001 Certified” Suppliers Are Not Equally Audited

Certification appears on quotations as a logo. Two things are worth checking behind it.

3-Certificate Scope Check

Check	What to ask for	Why	Verified
1. Scope statement	The certificate itself, and the activities and site named on it	A certificate covering a trading office does not cover a factory	______
2. Standard and edition	ISO 9001:2015 today; ask what the transition plan is for the next edition	ISO’s own page states that ISO 9001:2015 is about to be withdrawn and replaced; the sixth edition was at the “under publication” stage with publication expected in September 2026 — check iso.org for its current status before relying on this sentence	______
3. Packaging-specific scheme	Whether a GFSI-benchmarked packaging scheme applies — BRCGS Global Standard Packaging Materials is at Issue 7, published 28 October 2024, with position statement P708 amending clauses 4.4.1 and 4.8.2 effective 10 August 2026	A food or cosmetic customer’s own auditor will ask for this, not for ISO 9001	______

A note on documentary credits while we are on paperwork. If you are paying by letter of credit, the rules that govern the bank’s examination of documents are ICC Publication 600, the Uniform Customs and Practice for Documentary Credits, 2007 revision, in force since 1 July 2007 and still current, with eUCP version 2.1 in force since July 2023 for electronic presentation. A discrepancy is decided against the documents, not against the goods.

Ask for the certificate itself rather than the logo, and read the scope line — it takes a minute and it is the only part of a certificate that varies.

A Worked Example, From Two Quotations to One Decision

A buyer has two quotations for our 100 g body with a single-colour printed lid, 20,000 pcs, shipped to Rotterdam.

6-Step Landed Cost Trace

Step	Quote A	Quote B	Effect
1. Stated unit price	USD 0.285 EXW	USD 0.310 FCA Ningbo	A looks 8% cheaper
2. Tooling ÷ 20,000	USD 1,800 → +0.090	Existing tool → +0.000	A now 0.375 vs B 0.310
3. Set-up ÷ 20,000	USD 260 → +0.013	USD 300 → +0.015	Near parity on this line
4. Incoterms normalised	EXW → buyer arranges export clearance and inland haulage; ICC advises FCA instead where goods cross a border	FCA at a named place	Restate A as FCA before comparing; the added cost and the added risk both sit with the buyer under EXW
5. Duty and classification	Lid invoiced separately → a second HS line under 8309	Lid presented with the tin → one line under 7612	Two rates on one shipment for A; one rate for B
6. CBAM	Both are CN 7612 and therefore in scope; embedded-emissions data required from the producer		Decided on B, on total cost and on the supplier able to supply emissions data

Note what did the work. The 8% headline gap closed at step 2 and reversed. Steps 4 to 6 did not change the arithmetic much — they changed which supplier the buyer could actually operate with. That is the usual pattern.

For reference, our own commercial terms across all four standard bodies are 5,000 pcs minimum per SKU and 15–20 days production after artwork approval. Both move with print complexity, and both should be confirmed on your quotation rather than assumed from a web page — including this one.

Send both quotations through the 7-Line Quote Normaliser before you reply to either supplier — the questions it generates are also the fastest way to find out which of the two is easy to work with.

2026 Sourcing Pressure: CBAM Is Live and Incoterms 2030 Has Begun

Two things to plan around this year rather than react to.

CBAM’s definitive period started on 1 January 2026 and heading 7612 is inside it. For an EU importer this is a new recurring obligation attached to a product that has always been ordinary packaging, and the data it requires has to come from the factory. Suppliers who have never been asked for embedded-emissions figures will take time to produce them; the ones who already can are worth identifying now.

ICC has begun work on Incoterms® 2030. The ICC 2026 Global Policy Commissions Workplan states, under Commercial Law and Practice, that work will begin on the revision of the Incoterms® rules, laying the groundwork for Incoterms® 2030. No draft text and no publication date have been announced, and Incoterms® 2020 remains the current edition — but long-term supply agreements being signed now will still be running when the next edition lands, which is an argument for referencing the edition explicitly in the contract rather than writing “Incoterms” unqualified.

Write the edition year into every contract term this year — “FCA Ningbo, Incoterms® 2020” rather than “FCA Ningbo” — so that a future revision does not silently change what you agreed.

How the Numbers in This Article Were Calculated

The tooling amortisation figures are straight division of a stated charge by a stated quantity and are illustrative of the method, not quotations. The two-quotation worked example is constructed to show the arithmetic; its prices, tooling charges and set-up figures are invented for that purpose and are not our prices or anyone else’s.

Duty rates are stated as the general rate for the named line at the time of writing and are given to show where they sit in the formula, not as a basis for a landed-cost model. Tariff lines, trade-remedy scope and CBAM thresholds all change by regulation, frequently more than once a year. Take every rate from the current HTSUS or TARIC for your date of import; the applicable Section 232 rate for a specific aluminium line depends on the annex in force and is not reproduced here for that reason.

The volumetric divisors are as published by IATA and by DHL respectively; the 20% difference between them is the arithmetic ratio 6,000 ÷ 5,000 and applies only where volumetric weight exceeds actual weight, which is the usual case for tins but should be checked per shipment using the 2-Divisor Freight Check.

The statement that no international body publishes a standard or model clause on mould ownership is based on a review of the ISO catalogue, the WCO and UNCITRAL instruments, and ICC’s full model-contract catalogue in September 2026. Legal provisions quoted from the CISG are taken from UNCITRAL’s own published text. Nothing here is legal advice; a contract for tooling should be reviewed by a qualified lawyer in the relevant jurisdiction.

Frequently Asked Questions

Is the cheapest quote per piece the cheapest quote?
Usually not, and the gap is normally decided by tooling amortisation rather than by anything visible on the quotation. Divide every one-off charge by the quantity you will actually order in year one, then compare. A tooling charge is ten times heavier per piece at 5,000 units than at 50,000.

Do I own the mould if I pay the tooling charge?
Not automatically. There is no international standard on mould ownership — ICC, ISO, WCO and UNCITRAL publish nothing on it — so ownership is whatever your contract says, and if it says nothing, the supplier’s terms or local law decide. Get the owner, the storage location and the termination position written on the purchase order.

Should I buy FOB or EXW from a Chinese supplier?
For containerised goods, generally neither. FOB belongs to the sea-and-inland-waterway family and stipulates delivery on board a vessel, which does not match how containers move; ICC publishes guidance recommending FCA with CPT or CIP instead. ICC also advises preferring FCA to EXW wherever goods cross a border.

What HS code is an aluminum tin?
Heading 76.12, subheading 7612.90 for a rigid tin. A screw lid invoiced separately falls under heading 83.09 instead, so one shipment can carry two codes and two duty rates. The importer of record is responsible for the classification regardless of what the supplier wrote.

Does CBAM apply to aluminum packaging?
Yes for heading 7612, which is listed in the Commission’s aluminium sector guidance; CN 7615 household articles are excluded. The definitive period began on 1 January 2026, and the embedded-emissions data an importer must report has to come from the producer, so it belongs in the supply agreement.

Why do two freight quotes differ for identical cartons?
Most often the volumetric divisor. IATA’s published general rule divides by 6,000 and express carriers commonly divide by 5,000, which is a 20% difference in chargeable weight for a low-density product before anything else changes. Ask which divisor was used.

Is a sample charge worth paying?
Yes, if the sample comes from the production tool. Under CISG Article 35(2)(c) the approved sample becomes the standard the goods must conform to, so a hand-made sample makes a weak reference point for a claim while still being the reference point.

Getting a Comparable Quotation

Send your quantity for year one, your destination market and how you intend to ship. We will quote with tooling, set-up and samples on separate lines, state the Incoterms rule and named place, give you the carton data your forwarder needs, and tell you which HS code we will declare for the tin and for the lid. If an existing standard body fits your drawing, we will say so — that removes the tooling line entirely.

Send your requirement for an itemised quotation — 5,000 pcs minimum per SKU, 15–20 days production after artwork approval, samples available before bulk. See also our guide to choosing an aluminum tin supplier and our screw-top body specifications.
