Piece Price Is Not Your Cost: The Landed-Cost Stack
A supplier quotes $X per piece. Six weeks later, your finance team asks why the part costs noticeably more than $X by the time it reaches your dock — and both numbers are correct. The difference is the landed-cost stack: everything between the factory gate and your warehouse. Comparing suppliers on piece price alone is one of the most common — and most expensive — sourcing errors in PM procurement.
| Cost Element | What Drives It | How to Pin It Down at Quotation |
|---|---|---|
| Ex-works piece price | Material grade, density, part complexity, volume tier | The quote itself — check what volume the price assumes |
| Tooling amortization | Tooling cost spread over assumed volume | Ask whether tooling is in the piece price or separate; see our tooling ownership guide |
| Export packaging | Weight, fragility, corrosion protection for sea freight (VCI, desiccant) | Ask what packaging the quote includes — and what the upgraded option costs |
| Inland transport (factory → port) | Distance, truckload consolidation | Usually inside FOB price; confirm |
| Ocean freight | Container vs. LCL, route, season; fuel surcharges | [Per-cubic-meter share for LCL / per-container for FCL — get the assumption in writing] |
| Marine insurance | Cargo value, route | Small percentage of value; confirm who places it under your Incoterm |
| Import duty | Your HTS classification and origin — see below | [Duty rate for your HTS code — your broker confirms] |
| Additional duty measures | Trade measures on China-origin goods (e.g., Section 301 lists for the US) | [List status of your HTS code — check with your broker before committing] |
| Port handling, customs entry, brokerage | Fixed fees per shipment | [Per-entry fees — broker quote] |
| Destination inland transport | Port → your dock | [Your domestic freight rate] |
| Quality, rework, and inventory carrying | Reject lots, inspection at receipt, safety stock against sea freight lead time | Easy to underestimate — estimate it explicitly |
The bracketed variables are deliberate: these numbers move with routes, trade policy, and your own logistics contracts, and any supplier who "includes" them in a quote without stating assumptions is guessing on your behalf. What you should demand instead is that every quote states its basis — which is exactly what the comparison template at the end of this page does.
Incoterms for PM Parts: FOB, CIF, DDP Compared
Incoterms (currently the Incoterms 2020 edition) define where costs and risk transfer between seller and buyer. Three terms dominate PM part imports, plus one that looks attractive and usually isn't:
| Incoterm | Risk Transfers | Seller Arranges | Watch Out For |
|---|---|---|---|
| FOB (named port) | When goods are on board the vessel at the origin port | Export clearance, delivery to port, loading | You control freight and insurance — you see the real freight cost, and your forwarder's rates compete |
| CIF (named port) | Same on-board point as FOB | FOB plus ocean freight and insurance | Freight is inside the price — convenient, but the seller's freight markup is invisible; insurance is usually minimal coverage |
| DDP (named destination) | When goods are placed at the buyer's disposal at the named destination, import-cleared | Everything including import duty and clearance | Seller must act as importer of record in your country — often declined or conservatively priced by Chinese PM suppliers; complex for US/EU imports |
| EXW (factory) | At the factory door, not even loaded | Nothing beyond making goods available | Sounds safest, actually the worst of both for China exports: buyer handles export clearance from abroad, and local pickup arrangements are opaque |
The practical pattern for China PM sourcing: experienced importers tend to buy FOB and let their own forwarder control the ocean leg — this exposes the true freight cost and avoids CIF markup. First-time or low-volume importers often start with CIF or door-to-door arrangements for simplicity, then move to FOB as volumes justify it. DDP works for some destinations but expect it to be quoted conservatively or declined for markets where the seller cannot practically act as importer of record; EXW is best avoided for China exports altogether unless you have your own agent on the ground. None of this is judgment about any supplier's honesty — Incoterms are simply a cost-allocation contract, and you should choose the allocation that makes costs visible to you.
Duty and HTS: Where PM Parts Actually Classify
This is where honest sourcing pages get vague, so let's be precise about what can and cannot be said. Import duty in the US and most other markets is driven by the HTS/HS classification of the specific article — and PM parts do not classify as a single "powder metallurgy" category. Classification follows the article itself: a sintered gear generally classifies with gears, a sintered filter element with filtering machinery elements, a sintered bearing with bearings — and within a category, the material (iron/steel, copper, stainless) can change the subheading and the rate. We are a manufacturer, not a customs adviser, and we deliberately do not quote HTS numbers or duty rates on these pages.
What we do recommend:
- Have your licensed customs broker classify the actual part (drawing + material + function) before you finalize sourcing — classification drives both the base duty rate and which additional measures apply.
- Ask about additional measures explicitly. For US imports from China, Section 301 lists add duties to many steel articles; whether your classification is listed materially changes the landed cost. This is a broker question with a document answer, not something to leave to a supplier's guess or an internet search.
- Confirm country-of-origin marking requirements for your market before first shipment — mis-marked goods can be held at port.
- Keep the classification decision documented — if a shipment is examined, you want the rationale on file, not improvised.
Suppliers can help by providing composition and function data; we provide material declarations for our parts precisely so your broker can classify confidently.
Building a Quote Comparison That Doesn't Lie
The fix for all of the above is to compare quotes on a normalized landed basis: rebuild each quote to the same reference point — what one delivered part at your dock costs you. Build the table below for each supplier, where the reference Incoterm is FOB (the cleanest comparison basis) and the landed column is completed with your own freight, duty, and handling numbers:
| Line | Quote A | Quote B | Notes |
|---|---|---|---|
| Piece price at quoted volume | State the volume each assumes | ||
| Tooling: amount and ownership terms | Separate or amortized; title to whom | ||
| Packaging included | Sea-worthy? VCI/desiccant for corrosion | ||
| Incoterm quoted | Normalize non-FOB quotes before comparing | ||
| Payment terms | Financing cost of deposit/credit terms | ||
| Quality documentation included | Certs, dimensional reports — extra or included | ||
| Your freight + insurance to door | Same basis for both columns | ||
| Duty + additional measures (broker-confirmed) | Same HTS assumption, documented | ||
| Landed cost per piece | The number that actually compares |
And the eight questions that make suppliers show their basis: (1) What volume does the piece price assume, and what are the price breaks? (2) Is tooling separate or amortized — and who holds title at what trigger? (3) Which Incoterm is this quoted to, exactly? (4) What packaging is included, and what does sea-worthy upgrading cost? (5) What quality documentation accompanies lots, and is it priced in? (6) What are the payment terms — deposit, balance, currency? (7) Can you provide material composition data for our broker's HTS classification? (8) What is the quoted lead time at this volume, and what governs it? Question 8 connects directly to our guide on MOQ and lead time for custom sintered parts.
For what to send a supplier so the piece-price line itself is comparable, see what to include in a PM quote request — incomplete RFQs produce incomparable quotes before Incoterms even enter the picture. And for who we are on the other side of this table: SinterWorks as a China PM manufacturer, with quotations that state their basis.
Frequently Asked Questions
Is DDP always the most expensive option for PM parts from China?
Not always on paper — but it is the option where pricing is least transparent. The seller must absorb duty, clearance, and destination risks, and rational suppliers price that uncertainty in. DDP can make sense for small first orders where simplicity outweighs cost; for recurring production volumes, FOB with your own forwarder and broker is often the cheaper and more controllable structure.
Why do two suppliers quote the "same" PM part at very different piece prices?
Often because the quotes are not actually the same offer: different assumed volumes, different density or material interpretation of your drawing, tooling treated differently, packaging or documentation included in one and not the other, or different Incoterms. The normalized-comparison table above exists precisely to expose these differences. If after normalization a large gap remains, the next question is what each supplier understood the material and density requirement to be.
Do I need a customs broker for PM parts, or can I self-classify?
For anything beyond trivial value, use a licensed broker — PM parts sit in classifications where function and material both matter, and additional trade measures (anti-dumping, Section 301-type lists) can turn on classification details. Brokers classify against the actual part data; as the manufacturer we supply the material declarations and function data they need. The broker fee is small against the cost of a mis-classified container.
