Landed Cost 101: The Formula That Decides Whether You Make Money

Two importers buy the identical product at the identical US$10 FOB price. One makes 40% net margin; the other quietly loses money on every unit and doesn't discover it for six months. The difference is a single spreadsheet: the landed-cost calculation. It's the least glamorous document in importing and the most decisive — calculating your costs appropriately genuinely makes or breaks your import.

Landed cost = every dollar it takes to get one unit from the factory floor to your NZ warehouse, ready to sell. Not the supplier's price. Not the price plus freight. Everything.

The quick rule of thumb

For a low-duty destination like New Zealand, a useful first-pass estimate is supplier's FOB price + 20–30% ≈ landed cost. It's good enough for shortlisting ideas on your shopping list — and nowhere near good enough for a purchase order. Before real money moves, you build the full sheet and triple-confirm each line with the actual provider: forwarder, broker, insurer, platform.

Every line item, NZ edition

• Product cost (FOB): the supplier's quoted price, which under FOB terms includes delivery to the Chinese port. Include any export-packaging extras.
• Sea/air freight: mid-2026 indicative rates China→NZ: a 20ft container US$2,250–2,750; 40ft US$4,455–5,445; LCL around US$38/cbm; air freight about US$4.00/kg for larger lots; courier around US$6.71/kg door to door. Rates are volatile — quote, don't assume.
• Insurance: the standard is about 1% of product value. Cheap, and not the line to skip.
• Customs duty: 0% on virtually all Chinese-origin goods with a Certificate of Origin under the NZ–China FTA — make sure the supplier provides it. Otherwise most goods are duty-free anyway, with roughly 5–10% on categories like textiles, clothing and footwear. Confirm your HS code on tariff-finder.govt.nz.
• GST: 15%, calculated on (goods value + shipping + insurance + any duty). If you're GST-registered you claim it back — treat it as cash flow, not cost, but you still have to fund it at the border.
• Goods Management Levies: the new consignment-based border levies from 1 April 2026. Small on any one shipment, but per-consignment — one more reason to consolidate. Check customs.govt.nz for current rates on high-value entries.
• Broker and forwarder fees: customs entry lodgement, handling, documentation. Ask for the all-in quote.
• Inspection: ~US$300 for a third-party pre-shipment inspection. Non-negotiable on real orders.
• Testing and licence fees: lab testing where relevant (a few hundred US dollars), plus the fees suppliers never mention — Bluetooth licensing and Sisvel (MP3/MP4) royalties are the importer's cost, and skipping them risks customs holds or claims from licence holders.
• Domestic costs: transport from the port, storage, fulfilment, and your selling channel's fees when you calculate final profitability.

The worked example

Let's land 1,000 Bluetooth speakers in Auckland. FOB price US$10 each = US$10,000.

• Freight: ~3 cbm shipped LCL at ~US$38/cbm ≈ US$115 with minimums
• Insurance at 1% of product value: US$100
• Duty with NZCFTA Certificate of Origin: US$0
• Inspection: US$300
• Broker, entry and Goods Management Levy: allow roughly US$150 (confirm with your broker)
• Subtotal: ~US$10,665 — about US$10.67 per unit
• GST: 15% on (goods + shipping + insurance + duty) ≈ US$1,532 — funded at the border, claimed back if GST-registered

So a GST-registered importer's true landed cost is around US$10.67/unit — roughly FOB + 7%, well inside the rule of thumb, because this product is small, light and duty-free. Convert to NZ dollars at the day's rate, add local delivery and storage, then selling costs: on a marketplace, budget several percent for fulfilment and payment fees. If that unit retails at, say, NZ$49–59 in NZ, the margin story is obvious — and it was visible before ordering, which is the entire point.

Figure: Landed-cost build-up for 1,000 Bluetooth speakers from FOB price to NZ warehouse, showing each cost layer per unit.

Now rerun the same sheet for a bulky item — a US$20 product at 0.1 cbm each — and watch freight alone add US$3.80+ per unit before GST. Same formula, opposite verdict. That's the formula doing its job: killing bad products on paper instead of in your garage.

One sheet per product, forever

Make the landed-cost sheet a permanent habit: one per product, updated with actual invoiced figures once the shipment lands, so every reorder starts from real numbers rather than estimates. Costs drift — freight moves ~19% in a month during 2026, suppliers nudge prices, levies get reviewed — and your sheet is where drift becomes visible before it becomes losses.

Key takeaways

• Landed cost = FOB + freight + insurance + duty + GST + levies + fees + inspection — every line, triple-confirmed with the actual provider.
• FOB + 20–30% is a shortlist estimate only; for NZ with FTA duty at 0%, small light products often land far below that.
• GST (15% on goods + shipping + insurance + duty) is claimable if registered — cash flow, not cost, but budget to fund it.
• Watch the silent killers: freight on bulky items, licence royalties, and per-consignment levies on fragmented shipments.

Setting Up Right: NZBN, GST Registration and Your Customs Client Code

Here's a mistake we see constantly: a first shipment worth NZ$4,000 arrives at Auckland, and only then does the importer discover they need a Customs client code to clear it — while storage charges tick up daily at the port. The whole setup that would have prevented it takes a few hours, costs almost nothing, and can be done from your couch. Let's get you sorted before your goods are on the water.

There are three pieces of admin that matter: your NZBN, your GST position, and your Customs client code. Take them in that order.

1. Get your NZBN (and choose your structure)

Every NZ business gets a New Zealand Business Number. If you register a company, an NZBN is issued automatically; sole traders can apply for one free. Which structure should you choose? That's a conversation for your accountant, but the practical import angle is this: a company keeps the business's liabilities separate from your personal assets, which matters more for importers than for many other businesses — under NZ consumer law, when the overseas manufacturer has no NZ presence, you effectively carry the manufacturer's responsibilities for the products you bring in. Start as you mean to continue: separate bank account, and every invoice, payment record and supplier email filed from day one. You will need that email from four months ago; everyone always does.

2. Make the GST decision deliberately

GST registration is compulsory once your turnover exceeds NZ$60,000 in any 12-month period. Below that, it's voluntary — and this is where importers differ from most small businesses. When your goods cross the border, Customs collects 15% GST calculated on the value of the goods plus shipping, insurance and any duty. If you're GST-registered, you claim that import GST back in your GST return. If you're not, it's simply a cost.

So should you register early? For most people planning a genuine import business: yes. On a NZ$10,000 landed shipment, that's roughly NZ$1,500 of GST back in your pocket rather than baked into your costs. The trade-offs: you must charge 15% GST on your NZ sales, and you take on filing obligations. If you're doing a one-off toe-dip with a few hundred dollars of stock, staying unregistered is defensible; if you're building a business, register.

One 2026 note: the new Goods Management Levies that replaced the old border fees from 1 April apply to all importers per consignment, GST-registered or not — even small low-value consignments attract a levy of a couple of dollars plus GST. There's no registration status that makes border levies disappear.

3. Get your Customs client code before you ship

For any consignment worth more than NZ$1,000, NZ Customs requires the importer to have a client code — a unique identifier for you or your company — and the shipment also needs a supplier code identifying the overseas supplier. You apply through Trade Single Window (TSW), Customs' online portal, and you'll need your NZBN and identification documents to hand. In practice, your customs broker can apply on your behalf and will usually sort the supplier code at the same time; if you have a broker lined up (you should — see our roadmap post), just ask them.

Do this before your first shipment leaves China, not when it lands. A missing client code doesn't stop goods arriving; it stops them clearing, and delays at the wharf cost real money.

The supporting cast

While you're in setup mode, three more things worth lining up:

• A customs broker and freight forwarder. The broker lodges your import entries through TSW; the forwarder moves the goods. Get both relationships established before you order.
• Accounting software that handles GST returns — reconciling import GST manually gets old fast.
• A document system. One folder per supplier (quotes, certificates, licences), one folder per order (PO, invoice, packing list, Bill of Lading, inspection report). Customs and IRD can both come asking; tidy importers have boring audits.

What this all costs

Almost nothing, which is why there's no excuse: NZBN registration is free, GST registration is free, the TSW client code application is free. Company incorporation costs a modest fee. Compare that with one day of container storage charges plus a rebooked delivery because your paperwork wasn't ready, and setup is the best-value work you'll do this month. For current specifics and forms, go straight to the sources: customs.govt.nz for client codes and levies, ird.govt.nz for GST, and business.govt.nz for structure guidance.

Key takeaways

• Get your NZBN, then decide GST registration deliberately — registered importers claim back the 15% import GST.
• GST registration is compulsory past NZ$60,000 turnover in 12 months; voluntary before that, and usually worthwhile for a real import business.
• Shipments over NZ$1,000 need a Customs client code (via TSW) and a supplier code — arrange them before goods ship, ideally through your broker.
• Set up document discipline from day one: one folder per supplier, one per order.
