Balikbayan box weight & size limits, by courier

Box dimensions and weight caps are set by each courier and differ by tier and route, so a single chart goes stale. The check that lasts: confirm these, in writing, with your courier before you pack.

Confirm with the courier before packing

• Exact internal dimensions for each box tier they sell (small / medium / large / jumbo)
• Maximum weight per box tier — and the fee if you go over
• Whether they price by tier or by actual weight on your route
• Oversize / overweight surcharge and how it’s calculated
• Single heaviest-item limit, if any
• Whether the contents list / declared value must match what’s inside

The ceiling that applies to every courier is the customs one, and that part is sourced:

Two limits, and you can hit either one first

A balikbayan box has two independent ceilings, and they are not measured in the same unit:

• The courier limit is physical — the box’s dimensions and its weight, capped per tier. Exceeding it triggers a surcharge or a refusal at drop-off.
• The customs limit is financial — the declared value of the contents, capped by the Bureau of Customs at ₱150,000 per box, with the privilege availed up to three times per calendar year, regardless of which courier carries it.

These are not the same line. A jumbo box of pillows and clothing can be at the weight cap while nowhere near the value ceiling. A small box of phones and tablets can be well under every courier limit and still blow past ₱150,000 in declared value. Whichever you hit first is the one that bites — which is why packing to only one of them is how the other one surprises you.

Why a single size chart goes stale

Courier dimensions are not an industry standard. They are set per courier, often per tier name that does not mean the same thing between couriers, and sometimes per route. A “medium” at one courier is not a “medium” at another, and a published table of those numbers is wrong the moment a courier revises a tier or a route. That is the reason this page does not carry courier dimension figures it cannot attribute to the courier’s own page: an uncited measurement that looks authoritative is worse than a clear instruction to confirm it, because the reader packs against the wrong number with full confidence. The confirm-first checklist is not a placeholder for missing data — it is the answer that stays correct when the courier’s table changes.

Why each confirm-line matters

The checklist is not generic diligence — each line maps to a specific way a box goes wrong:

• Internal dimensions per tier decide whether the goods physically fit the tier paid for; the wrong tier is repacking at drop-off, not a small overage.
• Weight cap and the overweight fee are where an under-priced tier becomes an expensive one — the cap matters less than what crossing it costs.
• Tier-priced vs actual-weight on the route changes the whole strategy: a tier-priced route rewards filling the box; a by-weight route penalises it.
• Surcharge basis is the line that turns a quoted price into the real price; how it is calculated matters more than that it exists.
• Single heaviest-item limit catches the dense one-item box (tools, a small appliance) that passes total weight but fails an item cap some couriers set.
• Contents list / declared value matching the box is the customs line, not a courier one: the declared value is what counts against the Bureau of Customs ₱150,000 ceiling, and a contents list that does not match what is inside is a customs problem regardless of which courier carried it.

That last line is why size and weight cannot be packed in isolation — the declared value travelling with the box is a third limit, and it is the only one of the three that is fixed and sourced.

How to read this

Couriers cap weight and size; customs caps value. They are separate limits and either can be the binding one. The sourced part of this page is the customs value ceiling, attributed to the Bureau of Customs; the courier dimensions are deliberately left as a confirm-with list rather than guessed numbers. The durable answer is the confirm-first checklist plus the sourced ceiling, kept current at least quarterly.

For how box pricing is built on top of these limits, see courier rates compared. For what is allowed inside the box at all, see what you can and can’t pack, and for packing a first box end to end, see the first-box checklist.
