Balikbayan box weight & size limits, by courier

A balikbayan box is measured against three separate ceilings, in three different units, and only one of the three belongs to the courier. The courier sets the box tier — its dimensions and its weight cap. Customs sets a volume cap (200,000 gross cm³ per box, CAO 01-2018 §3.2) and a value cap (₱150,000 per sender per calendar year, §4.2). The tier is not automatically inside the customs volume figure: several couriers post Large and Jumbo tiers above it. The two facts sit side by side below.

The check that lasts is not a chart of tier dimensions, because those change: 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 limits that apply at every courier are the customs ones, and that part is sourced:

Three limits, and any one of them can bind first

The three ceilings are counted over different things, so a box can pass two and fail the third:

• The courier limit is the tier: its internal dimensions and its weight cap. Exceeding it triggers a surcharge or a refusal at drop-off. Weight is the courier’s limit alone — no weight cap appears anywhere in CAO 01-2018, and LBC’s US sea-freight page posts box sizes but no maximum weight (checked 2026-09-06).
• The customs value limit is financial, and ₱150,000 is applied twice — to a single box’s contents (§7a) and to everything one sender ships in the calendar year (§4.2, §7b) — alongside the three-availment cap (§4.1, §7c), regardless of which courier carries it.
• The customs volume limit is the one most often missed, because customs is usually described as caring only about value. §3.2 defines a balikbayan box as “a corrugated box or other container or receptacle up to a maximum volume of two hundred thousand (200,000) gross cubic centimeters without regard as to the shape of the container or receptacle” (master copy on customs.gov.ph, checked 2026-09-06). That is about 7 cubic feet, and the comparison table above shows it sitting below the boxes several couriers post as their Large and Jumbo tiers.

So the customs volume figure is not a distant outer boundary that every courier tier fits inside. A 24×24×24-inch “Large” works out to about 227,000 gross cm³, above the §3.2 figure; the larger jumbo tiers run higher still. Comparing a posted box size to §3.2 is arithmetic — it is not a ruling that any particular shipment is over the limit, which is the Bureau of Customs’ determination on the shipment in front of it. What the comparison does is show that the tier a courier sells and the volume the order defines are two different measurements, and the bigger tiers cross the second.

Going over has two separate consequences in the order, and they are not alternatives. §3.1 is the assessment rule for the overage: “Any amount in excess of the allowable non-dutiable and non-taxable value shall be subject to the applicable duties and taxes.” §7 is the eligibility gate, written in different terms: the shipment is excluded from the duty-and-tax exemption and the simplified clearance procedure. One prices the excess value, the other decides whether the shipment gets the exemption and the simplified route at all, and both operate on the same shipment rather than one replacing the other (master copy on customs.gov.ph, checked 2026-09-06). What happens to an excluded shipment beyond that is not set out in the order, and is the Bureau of Customs’ determination.

Courier dimensions vary by tier and route

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. LBC’s US sea-freight page posts a Small at 24×18×9 in and an Extra Large at 24×18×24 in (checked 2026-09-06); Highlight Express posts a “Large” at 24×24×24 in (checked 2026-09-04) — a bigger box than LBC’s Extra Large. 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. The dimensions on this page are each courier’s own posted figures on the date checked; confirm the current numbers before packing.

What each confirm-line covers

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 two separate numbers and the courier sets both: the cap is the tier’s ceiling, the fee is what applies once a box crosses it. A tier can read cheaper on the posted rate and land higher on the invoice, so both figures come out of the same confirmation.
• 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 invoiced one. A flat charge per box, a per-pound rate on the overage, and a bump to the next tier’s price are three different calculations off the same extra weight, so the basis is a separate question from the amount.
• 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 this box adds to the sender’s ₱150,000 for the calendar year (Bureau of Customs, CAO 01-2018 §4.2), 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 the courier tier cannot be packed in isolation — the declared value travelling with the box is a limit of its own, and value and volume are the two that are fixed, sourced, and identical at every courier.

How to read this

Couriers cap weight and their own tier dimensions; customs caps value (§4.2) and volume (§3.2). Three limits, three units, and any one of them can be the binding one — including a courier’s own Large or Jumbo tier landing above the §3.2 volume figure, which the comparison table shows by arithmetic. The sourced part of this page is the customs side, attributed to the Bureau of Customs, plus each courier’s own posted dimensions on the date checked; the weight caps and surcharge bases are a confirm-with list. The tables are kept current at least quarterly.
