Country-of-Origin Marking for Auto Parts Imported from China
US customs requires every imported part, or its container, to show the English name of its country of origin. What the rules in 19 CFR Part 134 say, when the box is enough, the 10% marking duty, and what to put in your purchase order.
Short answer: under US customs law, every article of foreign origin imported into the United States — or its container, where the rules allow — must be marked "in a conspicuous place as legibly, indelibly, and permanently as the nature of the article (or container) will permit" with the English name of the country of origin, so that the ultimate purchaser in the US can see it. For parts made in China that means "China" (typically "Made in China"). Articles that are not marked as required attract an additional duty of 10% of the final appraised value, unless they are exported or destroyed under customs supervision before the entry is liquidated. The rules are in 19 CFR Part 134.
For private-label buyers this is not a formality: the marking is cheapest and most durable when it is built into the part at the factory, so it has to be in your specification and purchase order.
What do the rules require?
19 CFR 134.11 requires that, unless excepted by law, "every article of foreign origin (or its container) imported into the United States shall be marked in a conspicuous place as legibly, indelibly, and permanently as the nature of the article (or container) will permit, in such manner as to indicate to an ultimate purchaser in the United States the English name of the country of origin of the article."
On the method, 19 CFR 134.41 says that "as a general rule, marking requirements are best met by marking worked into the article at the time of manufacture", and suggests that on metal articles the country of origin be "die sunk, molded in or etched". The marking must "survive normal distribution and store handling", and the ultimate purchaser "must be able to find the marking easily and read it without strain."
For auto parts, that translates into practical choices you should make with the factory:
- Cast or forged parts (rotors, drums, calipers, control arms, brackets) — cast or stamp "MADE IN CHINA" into the part.
- Machined or stamped steel parts — laser-etch or stamp.
- Rubber and plastic parts (hoses, boots, bushings, lamp housings) — mold the marking in.
- Small parts sold in a retail box — mark the box, and check whether the part itself also needs marking (see the exceptions below).
Who is the "ultimate purchaser" for a car part?
19 CFR 134.1(d) defines the ultimate purchaser as "generally the last person in the United States who will receive the article in the form in which it was imported". The regulation gives examples: if an article "is to be sold at retail in its imported form, the purchaser at retail is the 'ultimate purchaser'"; if a manufacturer substantially transforms the imported article, the manufacturer may be the ultimate purchaser; but if the manufacturing process "is merely a minor one which leaves the identity of the imported article intact", the consumer or user who gets the article afterwards is the ultimate purchaser.
For a replacement brake pad, sensor or bearing sold through distributors and repair shops, the part keeps its identity all the way to the shop or vehicle owner, so the marking has to be visible to them — not just to your warehouse.
When is marking the container enough?
19 CFR 134.32 lists general exceptions to marking the article itself. Among them: articles "incapable of being marked", articles that "cannot be marked prior to shipment ... without injury", articles that can only be marked "at an expense economically prohibitive of its importation", and articles "for which the marking of the containers will reasonably indicate the origin of the articles". When an exception applies to the article, the container still has to be marked unless it is excepted too (19 CFR 134.11).
19 CFR 134.33 also has a "J-List" of article classes excepted from marking. Two entries touch auto parts: "Bolts, nuts, and washers" and "Bearings, ball, 5/8-inch or less in diameter". Even for J-List articles, the outermost container in which the article ordinarily reaches the ultimate purchaser must be marked.
Do not assume an exception applies to your part. Exceptions are decided by CBP; ask your broker, and if the volume justifies it, ask CBP for a binding ruling.
What wording is acceptable?
19 CFR 134.45 requires "the full English name of the country of origin", unless CBP has specifically authorized another marking. Abbreviations are acceptable only if they "unmistakably indicate the name of a country". "Made in China" or "China" is the safe choice; do not rely on an abbreviation or a Chinese-language marking.
What if my brand or packaging mentions the US?
This catches many private-label programs. Under 19 CFR 134.46, if "United States", "American", "U.S.A.", the name of any US city or location, or the name of another country appears on the article or its container and could mislead the ultimate purchaser about origin, the country of origin must appear "legibly and permanently in close proximity to such words ... and in at least a comparable size", preceded by "Made in", "Product of" or similar words.
So a box that says "Engineered in Detroit" or a part stamped with a US company address needs "Made in China" next to it, at comparable size.
What happens if parts arrive unmarked?
Under 19 CFR 134.2, articles not marked as required "shall be subject to additional duties of 10 percent of the final appraised value unless exported or destroyed under Customs supervision prior to liquidation of the entry". The 10% applies both to failure to mark and to failure to include words required to prevent deception. Ask your broker in advance how a marking problem would be handled at entry for your parts — the cheapest fix is always the one made at the factory.
Can parts be routed through another country to change their origin?
Not by repacking or minor processing. 19 CFR 134.1(b) defines country of origin as "the country of manufacture, production, or growth", and further work in another country only changes the origin if it effects a "substantial transformation" (for goods of a USMCA country, the Part 102 rules apply instead). Relabeling Chinese parts in a third country does not make them that country's product — and for goods under an antidumping order, such as tapered roller bearings, Commerce's deposit instructions already reach non-Chinese exporters supplied by Chinese producers (see how to source wheel bearings and hub assemblies).
What should go in the purchase order?
- Marking text — "MADE IN CHINA", in English, at a stated minimum character height.
- Method and location for each part number — cast, stamped, etched or molded; on which face; visible after installation where practical.
- Container marking — the inner box and the master carton, including any retail packaging you supply artwork for.
- Brand artwork review — any US place names, "USA" or "American" in your branding, with the origin marking placed next to them at comparable size.
- Photo approval — photos of the marking on pre-production samples and on the first production lot, before the balance payment.
