Office supplies tend to be heavily import-dependent for Shopify merchants, and a large share of the category is sourced from China, which is part of why tariffs can weigh on them more than the modest base duty alone would suggest. Paper goods, binders, organizers, and writing instruments are often low-margin commodity items where a few points of added duty can erase the spread, and many of these SKUs may carry Section 301 China tariffs and other add-on actions on top of the ordinary rate. When your sell price is set by a crowded market and you cannot easily raise it, an increase in landed cost tends to come out of contribution margin rather than the customer's wallet.
Representative 2026 estimate stacking base MFN duty (USITC HTS 2026 Rev.10), Section 301 on China-origin goods (USTR), Section 232 on autos and steel/aluminum/copper articles (CRS IN12545), and the 10% Section 122 surcharge that expires 2026-07-24 and is under appeal (Skadden). Your exact per-SKU duty depends on the precise HS code, which MarginGuard resolves from the live HTS schedule once connected. Not legal or customs advice.
Cambodia is a long-standing low-cost manufacturing base whose exports to the US now carry a reciprocal-era tariff load on top of the normal HTS base duty set by each product's classification. That stacking matters for landed cost: the country-specific load can apply on top of the base rate across many categories, so the duty you pay may no longer be just the historic base rate for your goods, though the exact treatment still depends on your product's HS code. Cambodia has no comprehensive US free trade agreement, so there is no across-the-board duty preference to fall back on, and the representative stacked rate in the box above reflects the current-era treatment. Because rates in this era are set largely through policy action and have been adjusted on short timelines, the number can change between order cycles, so treat it as a snapshot rather than a fixed input.
Cambodia is a genuine China alternative for apparel and footwear and a common first stop when diversifying out of China, but it is not a duty-free escape hatch. It carries its own reciprocal-era load, so the right comparison is Cambodia's stacked rate against China's stacked rate for your specific HS codes, not Cambodia against a pre-tariff baseline. The catch is twofold: the country load is set at the national level, while the duty you actually pay still tracks each product's HS classification, and rules of origin decide whether goods count as Cambodian in the first place. If fabric, components, or major assembly trace back to China, transshipment and substantial-transformation scrutiny can negate the benefit, and any preferential program you hope to use depends on meeting its origin rules. Treat Cambodia as a way to reduce, not eliminate, tariff exposure, and validate the landed-cost delta per SKU before committing volume.
That's a single SKU. Across a full catalog the tariff hits every imported product differently depending on its cost and price — which is exactly why margin damage hides until a quarter closes light.

For a $20 desk organizer from Cambodia at a 12% stacked rate, that means charging $16.80 to hold a 40% margin. Round to a clean price point and test it; the point is to stop selling underwater.
Duty on these goods is driven first by what the item is actually made of and what it does, not by the label "office supplies." Paper and paperboard products (notebooks, pads, envelopes, file folders) generally sit in HTS Chapter 48; printed paper goods like dated planners and calendars often fall in Chapter 49; plastic desk accessories, organizers, and binders frequently fall under Chapter 39; metal items like staplers, clips, and shelving tend to land in Chapter 73 or 83; and writing instruments (pens, markers, mechanical pencils) typically sit in Chapter 96. The attributes that move the rate include material composition, whether the item is "printed" versus blank, and any mechanical or electronic function. On top of the base MFN rate, a significant swing for many merchants is country of origin, since China-origin office goods can pick up Section 301 and other add-on tariffs that can add substantially to the underlying duty. The exact per-SKU number depends on the precise HS code and where the item was made; treat the representative rate on this page as a starting point, not your specific rate.
A common pitfall is "sets" and combination products. A desk organizer kit, a stationery gift set, or a planner bundled with sticky notes and a pen is not automatically classified by its dominant part; under the General Rules of Interpretation, a retail set is generally classified by the component that gives it its essential character, and mixed sets that cannot be resolved that way may default to the heading with the highest duty rate. Merchants also sometimes misclassify "printed" paper goods (such as a dated planner or a printed calendar that may fall in Chapter 49) as plain notebooks (Chapter 48), or treat a plastic-bodied item as paper because of its paper inserts, which can change both the chapter and the rate. Because the correct code turns on these details, confirm the classification of bundled and printed items rather than reusing the code from a single-piece version of the product. This is general guidance, not customs or legal advice; for a binding classification, work with a licensed customs broker.
Because a meaningful part of the office-supply tariff burden can be China-specific add-on tariffs rather than the base rate, a high-leverage step is verifying true country of origin and testing alternate sourcing. Countries such as Vietnam, India, and Indonesia may be worth pricing for paper goods and plastic stationery, and Mexico can be worth quoting for bulkier items where freight is a large share of landed cost. Be careful with "substantial transformation": simply repackaging or shrink-wrapping Chinese pens or paper in a third country generally does not change origin, since customs looks at where the goods were actually manufactured. For lighter SKUs, also confirm how recent changes to low-value (de minimis) duty-free entry may affect your model, since they can raise costs on small-parcel and dropship-style flows that previously fell under the threshold. This is general guidance, not customs or legal advice.
Why might my office-supply duty be higher than the base rate I looked up?
The base MFN rate is typically only the floor. Many office supplies are made in China, where Section 301 tariffs and other add-on actions can stack on top of the ordinary duty, so the effective rate can be substantially higher than the base. The actual total depends on your precise HS code and country of origin, which is why two similar-looking SKUs can land at very different rates. Use the representative rate on this page as a starting point and confirm your own code.
My products are notebooks, pens, and plastic organizers in one shipment. Do they share one duty rate?
Usually no. Each item is classified by its own material and function, so paper notebooks (often Chapter 48), pens (often Chapter 96), and plastic organizers (often Chapter 39) can each carry a different rate and different add-on tariffs. Applying a single blended rate to a mixed shipment can misstate your landed cost. Break the duty calculation out by SKU using each item's specific code.
Would moving my supplier out of China lower my landed cost?
It can, depending on the item and where it is genuinely made, because much of the office-supply burden can be China-specific add-on tariffs rather than the base duty. Sourcing the same goods from countries such as Vietnam, India, or Indonesia may drop those extra layers, though you would still pay the ordinary MFN rate. Make sure the goods are genuinely manufactured there, since relabeling or repackaging Chinese product in a third country generally does not change its origin for customs purposes.
Is sourcing from Cambodia cheaper than from China after tariffs?
Often, but not automatically. Cambodia carries its own reciprocal-era load on top of the base HTS duty, so the saving comes from the gap between Cambodia's stacked rate and China's stacked rate for your exact products, not from any duty-free status. Run the landed-cost math per HS code, since the answer can flip for some categories. This is general guidance, not customs advice.
Does Cambodia qualify for duty-free treatment into the US?
Do not assume so. Cambodia has no comprehensive US free trade agreement, and any preferential program is conditional on meeting its rules of origin, which depend on where materials and processing actually originate. Consider confirming eligibility for your specific goods with a customs broker before pricing a duty-free landed cost. This is general guidance, not customs advice.
Could goods I source from Cambodia be treated as Chinese for tariff purposes?
Possibly, if origin is not genuinely Cambodian. Customs generally looks at substantial transformation, and apparel and footwear typically have category-specific origin rules. If fabric or key components come from China and only light finishing happens in Cambodia, the goods may be treated as Chinese or flagged for transshipment, which can wipe out the intended saving. Keep supplier documentation that supports the country of origin you declare, and confirm the specifics with a customs broker. This is general guidance, not customs advice.
