Excavator Parts HS Codes: How to Classify Pins, Bushings and Teeth
Most excavator parts from China are declared under HS heading 8431, but the six-digit code below that depends on what the part actually is, not what it is called. Bucket pins and bushings made to a machine-specific part number usually sit in 8431.49, while standard bolts, plain bearings and rubber seals fall outside 8431 altogether — and in nearly every country it is the importer, not the Chinese supplier, who carries the liability for a wrong code.
What HS code do excavator parts use?
Heading 8431 covers parts suitable for use solely or principally with the machinery of 8426 (cranes), 8429 (dozers, graders, excavators, loaders) and 8430 (other earthmoving machinery). Within it, two subheadings do most of the work:
- 8431.41 — buckets, shovels, grabs and grips.
- 8431.49 — every other part of the machines in those three headings.
The machine itself is classified elsewhere. A tracked excavator is 8429.52; its bucket pins, bushings, track rollers and idlers are not, because they are parts, not the machine. Mixing the two is the most common classification error on a first shipment, and it is also the easiest to spot at destination.
Why do bucket pins and bushings often land in different codes?
The test customs applies is whether the item has a design feature that fits only that machinery. A bucket pin machined to a specific part number, with a retaining groove or a cross-drilled hole in a fixed position, passes that test and goes to 8431.49. The same pin sold as a plain unthreaded steel bar to a nominal diameter is a general fastener and can fall to 7318.29, or to 7326.90 if it does not fit the fastener description at all.
Bushings split the same way. A steel-backed or bronze bucket bushing bored to a specific housing size behaves commercially like a plain shaft bearing and can be declared under 8483.30. Machined as a numbered boom or bucket component, it goes back to 8431.49. The difference is not cosmetic: duty rates on 8483 and 8431 diverge in most tariff schedules, and so do the origin rules that decide whether a preferential rate is available at all.
What about bucket teeth, adapters and cutting edges?
Bucket teeth and the adapters they pin onto are parts of a bucket, so 8431.41 is the normal entry. Replaceable tips sold separately are treated differently by different administrations — some accept 8431.41, others push them to 8431.49. Rock-drilling tools are a separate world under 8207.19 and should not be mixed into an earthmoving entry. Bolt-on cutting edges and heel shrouds usually follow the bucket at 8431.41, or 8431.49 when they are supplied as a separate wear part rather than as part of a complete bucket.
Where do seals, bolts and bearings sit?
- Rubber seals, O-rings and gaskets — 4016.93, not 8431, when they are standard elastomer items.
- Mechanical seals — 8484.20.
- Track shoe and track roller bolts and nuts — 7318.15 for threaded bolts and 7318.16 for nuts, unless they are supplied as a matched set with a specific track group.
- Bearings — 8482, by bearing type, regardless of which machine they fit.
A single container will often need four or five different codes on one invoice. That is normal. What is not normal is one code covering the whole container because it was the code used last time.
Does the HS code change what you pay?
Yes, twice. First at the duty line: 8431, 8483, 7318 and 4016 rarely carry the same rate. Second at origin: free trade agreements set product-specific rules per heading, so a pin declared under 8431 may qualify for a preferential rate while the same pin under 7318 does not, or the reverse. There is no shortcut here — published rates change, and a rate copied from a blog post or an old invoice is worth nothing at the border. Check your own national tariff schedule for the current figure.
What should the commercial invoice show?
- The six-digit HS code on every line, not one code for the shipment.
- Part number and the machine model it fits, e.g. a 60 × 80 × 60 mm bushing for a Komatsu PC200-6.
- Material and production method — forged, cast, or machined from bar — because several national splits turn on exactly that.
- Net weight per line and country of origin.
- A description that a customs officer can match to the code without a phone call.
How do you avoid a classification dispute?
Ask for the code before the proforma invoice, not after the bill of lading. For any line you import repeatedly, apply for a written advance ruling in your own country — it is free or cheap in most jurisdictions and it moves the risk onto the authority. Keep the drawing or the sample that justified the ruling. And do not let a freight forwarder choose the code by default: forwarders are good at routing, and they are not liable for the duty you pay.
The practical summary: 8431.41 for buckets and teeth, 8431.49 for pins, bushings and track chain parts made to a machine-specific design, and a separate line for anything that is really a fastener, a bearing or a rubber part. Classify what the part is, and the paperwork stops being a gamble.
,000 went viral in Norway this autumn, and behind that video sits hard data: construction machinery exports reached US.373 billion in the first half of 2026, up 21.7 percent year on year according to the China Construction Machinery Association, with compact equipment and micro excavators driving the fastest growth.
What do the H1 2026 export numbers show?
The headline figures reported by Chinese state media in late October, drawn from industry association statistics: excavator exports exceeded domestic sales for the eighth consecutive month, and cumulative excavator exports passed 85,000 units in the first seven months of 2026, up more than 31 percent year on year. Exports to the European Union reached US.626 billion, up 28.9 percent. Industry forecasts put China's compact construction machinery sales for 2026 above 180,000 units, with micro excavators making up more than 60 percent of that, roughly 110,000 machines. Trade commentary attributes the shift to buyers outside the traditional channel: private owners, small farms and tradespeople in Europe and South America discovering these machines through social media and cross-border e-commerce rather than dealer networks.
Why does this matter to parts buyers?
Because every one of those machines is a compact wear-parts consumer. A 1 to 3 tonne excavator still runs bucket pins and bushings, teeth, track rollers and sprockets; it just runs them at smaller envelopes and tighter tolerances than a 20 tonne machine. The parts market for this segment behaves differently from the large-machine market in three ways:
- Volumes are high and per-unit margins are thin, so parts supply consolidates around the same Shandong manufacturing clusters that build the machines.
- Many compact machines are sold direct to first-time owners, so sourcing spare parts is often the owner's first experience with the brand. A parts page that does not answer "which pin fits my machine" loses that buyer instantly.
- Fleet-scale after-sales networks, the normal channel for 20 tonne iron, barely exist for micro machines, which pushes owners toward online parts suppliers and pushes suppliers toward clear part-number discipline.
What does this mean for a Shandong parts maker?
JALE Excavator Parts is a Shandong manufacturer of excavator wear parts, and it sits inside the same industrial cluster that is shipping these machines. Unlike most parts suppliers, it also builds its own compact range, including the JALE08, JALE10-1 and JALE12 mini excavators, so the fit between a small machine and its pins, bushings and undercarriage parts is designed rather than reverse-engineered.
Do compact machines need different parts discipline?
The wear parts are the same families, but the failure pattern is not. A micro excavator's pins and bushings are physically smaller, so a few tenths of a millimetre of wear is a larger share of the original clearance, and the symptoms, play at the bucket ear, grease that will not hold, a knocking sound on direction change, arrive sooner relative to machine hours. Owners who would never inspect a 20 tonne machine weekly can and should walk around a 1 tonne machine weekly: two grease strokes per pin, a visual check that the bucket ears have not bell-mouthed, and a feel for slop at the linkage. The parts themselves are cheap; the deciding factor is knowing the pin diameter and ear spacing before ordering, because a 25 mm and a 30 mm pin look identical in a photo.
One honest caveat: no association figures have been published for compact-segment parts demand specifically, so any claim about its size would be guesswork. What the export data does establish is the installed base: over 100,000 micro and compact machines a year are entering service, largely with owners who have no dealer relationship. Their pins, bushings and teeth will be replaced on wear, on the owner's budget, from whichever supplier answers first with the right dimensions. That is the market segment forming behind the headline number, and it buys the same discipline this site has always sold: correct part numbers, honest steel grades, and hardware that fits the first time.

.31 billion, up 47%, and to Latin America at US.03 billion, up 60.7%. Longer routes make schedule reliability worth more than a few days of inland saving, which is why the port and the carrier matter more than the canal itself.
What it means for a parts order in practice
Production time does not move. Machining, heat treatment and packing run at the same pace whichever port the container leaves from. What a shorter inland leg changes is the buffer a supplier needs between finishing an order and handing it to the carrier, and at the margin how much working capital sits in a container on a truck.
For the buyer, the response is unchanged: plan stock against ocean transit plus clearance, not against the inland leg, and ask for the port and the sailing date rather than a single lead-time number. The parts themselves — bucket pins and bushings, track chains, bucket teeth — are priced by steel grade and machining hours, not by which river they floated down.
.90 billion, up 13.9%; to Europe, US.59 billion, up 4.2%. The growth is elsewhere: Africa at US.31 billion, up 47%, and Latin America at US.03 billion, up 60.7%.
That regional split matters for spare-parts planning. Mature markets in Europe are growing slowly, while the fastest-growing destinations are markets where machines work long hours in abrasive conditions and where the dealer and service network is thinner — exactly the profile that generates high wear-parts consumption. Trade-press analysis attributes a large share of African excavator demand to mining, and mining duty is brutal on undercarriage and on ground-engaging tools.
What should buyers and distributors plan for?
Stock the models that are actually in the field, not the models in the press release. On the evidence of the last few years that means the mainstream 20–30 tonne classes and the household names built around them — PC200 and PC300 class machines, the 320 and 330 class, the EX200 class, the R210 class and the DX225 class — plus the undercarriage groups that fit them. Those are the machines absorbing pins, bushings and track components in volume.
Do not build stock around electric-specific parts yet. At 0.6% penetration there is no volume aftermarket, and the common parts on those machines are the same parts you already carry.
Finally, plan for the replacement cycle, not just the new-machine market. Chinese trade-press analysis puts the domestic replacement cycle at roughly eight years, and with domestic sales now rising on the back of equipment replacement and emission-standard upgrades, a large second and third-owner population of machines is coming into its maintenance-heavy phase. That is the cohort that buys the most wear parts per machine — and it is a diesel cohort.
