Are a spare part and its machine always under different codes?

Not always. Some machine headings state explicitly that they include parts dedicated to that machine, and such dedicated parts may fall under the machine heading; general-purpose items and parts not expressly covered follow other routes. The answer therefore differs by part and must be checked against the tariff, article by article — it cannot be generalised.

How do I decide whether a part is “dedicated”?

Look at design intent and compatibility: was it designed only for a particular model, and does it have a use once removed from that model? A custom part that fits only one model is dedicated; a bolt or bearing used across equipment is general-purpose, even if it is in practice used on just one machine.

How do I declare a consignment mixing machine spares and general-purpose items?

Judge each item and list it on its own line by code. Machine spares follow the dedicated-part route; general-purpose items are classified by their own material and function. Merging everything into one line of “assorted accessories” is the wording most likely to invite a challenge, and it cannot be explained at inspection.

Can I use “accessories for XX machine” as the product name?

Not as a declared product name. It gives no technical property of the part, so the classification cannot be judged. The correct wording is the part name plus dedication information — for example, “hydraulic gear pump assembly dedicated to the hydraulic system of a Model XX machine” — together with material, function and specification parameters.

What happens if a spare part is classified wrongly?

The same as any classification error: overpaid duty, or underpaid duty clawed back, or a regulatory judgement with no basis. Spare parts come in small batches but at high frequency, so an error repeats and accumulates. For parts supplied long-term, a single pre-ruling is worth doing once and for all.

Do spares that come with the machine have to be declared separately?

They must be handled by their actual nature: accompanying spares are listed separately on the invoice with the accompanying relationship noted, and the code follows their own classification logic. Keep them on a separate line from separately purchased spares, because the declaring context differs. Confirm the exact treatment for combining with the forwarder against the rules in force.

Is the classification of a general-purpose item entirely unrelated to its use?

Essentially yes. A general-purpose item is classified by its own material, function and specification — a bolt under its own heading, regardless of whether it is fitted to an excavator or a textile machine. That is the practical point of the dedicated / general-purpose split: a general-purpose item does not need to be classified separately for every machine.

If I export the same parts repeatedly, do I have to re-classify each time?

For an identical part with unchanged parameters the classification conclusion can be reused, but it is better to obtain a formal conclusion through a pre-ruling once and then declare against it. Watch the BTKI version updates and any change in specification: a change of material or model means the judgement has to be made again.

Why Spare Parts and Machines Often Fall Under Different HS Codes

Key figures (free to quote)

Item	Reference figure
Jakarta (Tanjung Priok) standard clearance	2-4 working days (complete documents, no inspection).
Jakarta inspection (yellow line)	3 working days standard + 7 working days inspection.
Jakarta red line	3 working days standard + 10 working days red-line handling.
Import duty (BM)	Typically 0-15% depending on HS code; FORM E / ACFTA brings most lines to 0%.
De minimis for duty	Goods valued under USD 3 are duty free (PPN still applies).
NIB / API processing	NIB 1-2 working days; API import licence 3-7 working days.
LS survey (Laporan Surveyor)	3-7 working days including issuance.
FORM E issuance	1-3 working days (issued by China Customs / CCPIT).

In short

Spare-part classification answers one question first: is it “a part of a particular machine”, or “a general-purpose item”? The two answers lead down completely different routes — and that is the root of why spare parts and complete machines often carry different HS codes.
Dedicated parts may be able to “follow the machine”; general-purpose parts are normally classified by their own nature. But following is not automatic — it depends on conditions the tariff states explicitly.
The most common error when shipping spare parts is declaring a part under the machine’s name. “Accessories for XX machine” is not a code in the tariff; it is a description. A spare part has to speak through its own technical properties.

1. Telling dedicated parts from general-purpose parts

The key distinction. “Dedicated” turns on design intent and compatibility, not on where the item happens to be used. A general-purpose bolt remains a general-purpose item even if it is used on only one machine; a custom part that fits only a particular model remains a dedicated part even if that model is common.

Dimension	Dedicated part	General-purpose part
Definition	Designed for a specific machine; no independent use once removed from it	An item used across many machines and industries
Typical examples	A gearbox specific to one model, a custom fixture	Bolts, bearings, motors, general-purpose valves
Classification route	May follow the machine heading (on the tariff’s stated conditions), or fall under a dedicated parts heading	Normally classified under the general heading for its own material and function
Basis of judgement	Design purpose and range of compatibility	Whether it is widely used across different equipment
Elements to emphasise	The dedicated target and the model it fits	Material, specification, general function

2. The conditions for a part to “follow the machine”

Many machine headings in the tariff state explicitly that they include parts dedicated to that machine — that is the basis for a part following the machine. But it is limited to the cases the heading expressly covers; it is not a general rule.
Parts that do not qualify each have their own destination: general-purpose items under the general heading; certain parts under a dedicated parts heading; parts of certain materials possibly under the chapter for that material. Check code by code — do not fall back on the impression that “they are all accessories”.
The benefit of following the machine is that the regulatory conditions and the rate match the machine; the cost of going the wrong way is a mismatch in rate and regulation. So spare parts must be judged item by item — not all declared under one impression code.
When a machine and its spare parts move on the same shipment, declare them separately: each on its own line under its own code. Do not merge them into a single line of “XX machine and accessories”.

3. The order to judge spare parts in

Step one: dedicated or general-purpose. Ask two questions — does it still have a use once removed from the target machine, and was it designed to fit only a particular model? If both answers agree, the direction is settled.
Step two: for a dedicated part, check whether the machine heading states that it includes parts. Where it does, check the parts subheading under the machine heading; where it does not, look for a dedicated parts heading, or judge by material.
Step three: classify a general-purpose part by its own properties. Material, function and specification fix the code — not who it is for.
Step four: verify the 8-digit position against the Indonesian BTKI. A Chinese code is a reference, not a conclusion — start from the HS lookup tool.
Step five: where it is in doubt, go to a pre-ruling. For large volumes of spare parts supplied long-term, a single pre-ruling solves the long-term problem — see the pre-ruling page.

4. How to write spare-part declaration elements

Element	Recommended wording	Avoid
Product name	“Hydraulic gear pump assembly dedicated to the hydraulic system of a Model XX machine”	“XX machine accessories”, “mechanical parts”
Dedication	“Fits only Brand XX, Model XX equipment; no other use”	“General-purpose accessory” (wrong for a dedicated part)
Material	“Alloy steel, case-carburised surface treatment”	“Metal”
Function	“Transmission assembly that delivers power to the XX position”	“Transmission part”
Specification	Outer diameter, tooth count, mounting hole positions and other checkable parameters	“See drawing” with no written parameters

5. Common errors and their correction

Error	Problem	Correction
Declaring a part under the machine’s name	A part does not have the machine’s function; the classification does not hold	Re-classify by the part’s own properties and dedication
One code for a whole consignment of spare parts	Different parts differ in dedication; the codes should differ too	Judge item by item and split across lines by code
Writing a dedicated part as a “general-purpose accessory”	The two routes can carry different rates and regulatory conditions	State the dedicated target and the model it fits, per the design purpose
Using only a Chinese trade nickname	Nicknames such as “flange” or “blind plate” map to several headings	Add technical parameters and a functional description
Mixing accompanying spares with separately purchased parts	Cargo accompanying a machine and cargo imported alone are declared differently	List separately by actual nature and note the accompanying relationship
