A tight weight margin and a wide size miss can sit on the exact same box.
The box against Jamaica's own numbers
USPS's Individual Country Listing for Jamaica, read on pe.usps.com 2026-08-21, holds Priority Mail International to 22 lb of weight, 42 inches of length, and 79 inches of combined length and girth. Set a boxed front bumper cover for a Honda Civic, packed to 56 × 20 × 12 in at 20 lb, next to those three lines and only the weight survives.
| Measurement | This box | USPS limit to Jamaica | Where it lands |
|---|---|---|---|
| Weight | 20 lb | 22 lb | Clear, by 2 |
| Length | 56 in | 42 in | Over, by 14 |
| Length plus girth 56 + 2×(20+12) | 120 in | 79 in | Over, by 41 |
A 2 lb margin on weight and a 41-inch miss on girth sitting inside the same box is the sharpest split this site has measured on any country's listing so far. It is a reminder to check every line separately: a part light enough to pass the scale can still be shaped entirely wrong for the carton this postal product allows.
No parts-specific ban, but paperwork on the other end
Jamaica's listing, read end to end on 2026-08-21, names no automotive part, battery or fuel item anywhere, so for a part small enough to meet the numbers above, size and weight are the whole story rather than a hidden prohibition. One other line in the same listing is worth flagging before anything ships, though.
Authorization sits with the recipient
The listing states that many categories of merchandise need an import authorization, obtained from the Trade Administrator's office in Kingston, and that this falls to the person receiving the box, not the person sending it.
Confirm before, not after
A part sent ahead to a relative or a shop in Jamaica can arrive needing paperwork nobody applied for yet. Checking with the recipient before the box ships avoids a shipment stalled at the other end.
Fluids still matter
Nothing in Jamaica's listing waives the general rule that a part still wet with fuel or oil does not belong in a box. Drain it dry the same as for any other route.
Priced live: the Miami leg, on record
A part bound for the Caribbean usually splits its trip: one domestic label to a forwarder, then whatever export or courier arrangement carries it over the water. Miami carries a heavy concentration of forwarders serving Jamaica, and this site quoted the identical box on that exact route earlier the same day for our companion international car-parts guide, so the figures below are that same capture rather than a second run of the same box on the same lane.

These rows stop at the Florida coast and change nothing about the ceilings above — they exist so the first of the two bookings carries a captured number rather than an assumption. What the forwarder or courier charges for the actual crossing into Jamaica, and whether the recipient's import authorization is already in hand, are separate questions this table does not answer.
Where these rules come from
- USPS, Individual Country Listing: Jamaica — the 22 lb, 42 in and 79 in Priority Mail International limits, and the import authorization note. Read 2026-08-21.
- Price: our own capture against SMKlog production checkout on 2026-08-21, from Berkeley Heights, NJ 07922 to Miami, FL 33101 — the same box and lane priced for this site's international car-parts guide, reused rather than re-run. Live checkout output, not a rate card.
USPS revises country listings without notice. Everything above traces to the single date this page names, 2026-08-21, and re-reading the listing before a shipment actually moves costs nothing.
Common questions
Can you ship car parts from the US to Jamaica?
Jamaica is not among the four countries SMKlog's checkout sells online (those are Canada, the UK, Germany and Australia), so the crossing itself is priced by whoever handles the Jamaica leg, not by us. What we can quote is the domestic run to a Miami forwarder: our own boxed bumper cover ran $101.87 to $183.45, captured 2026-08-21.
Does a boxed car part clear USPS's weight limit to Jamaica?
Barely. USPS's country listing for Jamaica, read 2026-08-21, caps Priority Mail International at 22 lb - the tightest weight ceiling this site has found for a Priority Mail International destination. Our 20 lb bumper cover box clears it, but by only 2 lb, a margin thin enough that a slightly heavier part in the same size box would fail it.
What about the box's length and girth?
Both fail, by a wide margin. Jamaica's listing sets a 42-inch maximum length and a 79-inch combined length-and-girth ceiling, read 2026-08-21. The same 56 x 20 x 12 in box that squeaked past the weight line runs 14 inches over on length and 41 inches over on length plus girth - the largest girth miss this site has measured against any country's Priority Mail International listing.
Is there a rule against mailing auto parts specifically to Jamaica?
No. The listing, read end to end on 2026-08-21, names no automotive part, car battery or fuel item anywhere. The size ceilings above are what actually stop this particular box; a smaller, lighter part would still meet Jamaica's general rules on its own merits.
Does the recipient need paperwork on the Jamaica side?
Often, yes. Jamaica's listing states that many categories of merchandise need an import authorization, and that it is the addressee, not the sender, who has to obtain it from the Trade Administrator's office in Kingston before the shipment arrives.
